We are seeing a monumental movement in the radio communication industry, as this very technical article shows the transition from hardware to software within the radio communication industry is just around the corner. With 3G and 4G providing Data and Voice Comms covering large distances, RF communication will find it hard to compete, the simple answer seems to be Tetra, but is that long term? There will always be a need for point to point communications, but larger comms infrastructures could possibly be managed in a different way.

With the evolution of digital electronics the radio market and communication technologies have evolved a lot. Though the concept of software defined radio (SDR) is not new, in the recent years, this market has undergone many changes in terms of technology and uses. SDR is a type of radio communication system where communication is carried out by the use of software on embedded system or personal computer instead of implementing hardware such as filters, amplifiers, mixers, detectors, demodulators and modulators, among others. SDR are capable of transmitting and receiving a wide spectrum of frequency. When the data from a source is converted into digital format, the remaining activities involved in radio communications are carried out with the help of software driven automated functions.

SDR optimizes the tactical information system as embedded software used in SDR helps in the dynamic selection of the communication channel. The number of digital service users is increasing resulting into the improved adoption rate of software defined radio. Public safety, military and commercial use are the three major end-use applications of SDR systems. The demand for SDRs in expected to increase in coming years owing to efficiency and cost effectiveness offered by them. The industry has undergone transformation from analog to digital. Thus, the advance capabilities of digital radio are expected to drive the growth of SDR market. Multiple regulations govern the SDR market and this affects the market growth and trends. For instance, the Federal Communications Commission (FCC) legally created a newer class for equipment of SDRs that had streamlined equipment authorization procedure.

Military modernization programs being carried out by several countries such as South Korea, India, Germany, Japan and the U.S and the interoperability provided by SDR are major driving forces for SDR market. The issues faced in the integration of the various sub systems pose a challenge to the SDR market. Further, the development of software platforms, technologies and tools, which allow flexible specification, design and implementation of radio systems, is another significant challenge. Players in software defined radio market have potential opportunity in technical advancements of SDR technology such as resolving the problem of frequency congestion, wide frequency range (spectrum) and improved broadcasting services in future.

Software defined radio market is segmented on the basis of type, end-user application and geography. On the basis of type of SDR, the market is segmented into ideal software defined radio, baseband software defined radio (BBSDR) and high frequency software defined radio (HFSDR). On the basis of end-user industry, SDR market is segmented into defense industry, telecom industry, manufacturing plants, public safety vendors and personal use. U.S. Canada, Japan, France, Brazil, South Korea, India, Germany and Italy have emerged as the leading countries for software defined radio market.

Some of the key vendors in software defined radio market are BAE Systems PLC, Elbit Systems Ltd., IndraSistemas, L3 Communications Corporation, Raytheon Co., Rohde & Schwarz GmbH & Co KG, Thales Group, Viasat Incorporated, SAAB AB, Rockwell Collins, Northrop Grumman Corp., ITT Corporation, Harris Corporation and Datasoft Corporation, among others.

Motorola have always been a brand we have looked up to, in our eyes they produce some of the best equipment on the market, sometimes they don’t sell as well as they should do. The business has been split and sold several times over the last year, but they are now on the rise and business is going well, as this article shows.

2014 saw Motorola’s ownership change hands from the west to the east. Lenovo acquired the company off Google on January 29, 2014 but it was not until 2016 that the fruits of Lenovo’s ownership started showing up.

The year started off with Motorola in a slightly vulnerable position with the relative failure of both the Moto X Style and Moto X Play. The Moto X line was fading and even the third generation Moto G had failed to impress.

These first devices under Lenovo’s ownership however, had been in the pipeline much before Lenovo took over and it was not until the Moto G4 and the Moto Z in 2016 that we saw what the new Motorola could deliver.

Moto G4 series: Ushering in a renaissance

The Moto G4 Plus was one of two variants of Motorola’s fourth generation Moto G, the firm’s bestselling smartphone range ever. This was the first time Motorola (now owned by Lenovo) launched more than one smartphone in the G range, with the Moto G4, Moto G4 Play and the Moto G4 Plus.

At a starting price of Rs 13,499, the Moto G4 Plus made for a compelling buy, and continued the G series of smartphone’s tradition of providing good smartphones at an affordable price. With a superb display, a fast and accurate fingerprint sensor, stock android and great performance, it ticked all the right boxes for a mid-range device.

In comparison to the regular Moto G4, the Moto G4 Plus featured an improved 16MP rear camera with phase auto detection, laser autofocus and a dual LED Flash and also came with a fingerprint sensor.

Motorola also released the Moto G4 Play which was the cheapest device in the G4 lineup at Rs 8,999 and packed a 5-inch 720p HD display, a 2,800mAh battery, 2GB of RAM and 16GB of expandable internal storage.

The Moto G4, G4 Plus and G4 Play were critical as well as commercial hits and announced the comeback of Motorola in the smartphone game. The Plus in particular, presented a fantastic blend of features and affordability that saw it shoot up the sales charts.

Moto E3 Power: The odd one out

Lenovo also unveiled the Moto E3 Power in India which was a more powerful version of the third generation Moto E3. In a surprising move, the company decided against releasing the regular Moto E3 in the country.

The Moto E3 Power came with a massive 3,500mAh battery, 2GB of RAM, a 5-inch HD display and nearly stock Android Marshmallow.

At Rs 7,999, the Moto E3 Power found itself in as odd situation with the much more capable Moto G4 Play priced at just a thousand rupees more.

The attack of the Modular smartphones

Motorola then cemented its position in the smartphone world by releasing the striking Moto Z, the company’s most exciting smartphone in years.

The Moto Z came packed to the gills with a Qualcomm Snapdragon 820 SoC, 4GB of RAM, a 13MP rear camera with OIS and 4K recording, a 5MP front shooter and a 2,600mAh battery along with TurboCharging support.

The ‘World’s thinnest premium smartphone’ came with a 5.5-inch QuadHD display protected by corning gorilla glass, a sleek and suave metal/glass body and unlimited feature expansion through the Moto Mods.

The distinguishing feature of the Moto Z were the ‘Moto Mods’: snap-on accessories that could be attached to the back of smartphone through magnets in order to increase its functionality.

Alongside the flagship Moto Z, Motorola also launched its younger brother, the Moto Z Play which came with a 5.5-inch 1080p Super AMOLED display, a downgrade from the QuadHD resolution of the Moto Z and the largest battery Motorola ever put in any of its smartphones. Just like the Moto Z, the Moto Z Play also supported the innovative Moto Mods.

The Moto Z and Moto Z Play helped bring Motorola back into the spotlight. The Moto Mods in particular were greatly appreciated and were hailed as one of the best implementations of the modular concept in recent years.

The stunning all-metal Moto M

The end of the year saw Motorola launching the stunning all-metal Moto M in India.

The Moto M’s full metal unibody design with antenna bands on the top and bottom edges was a complete departure from the design language of previous Motorola smartphones and was again an indication of the company’s new ownership.

This is what Sudhin Mathur, Executive Director, Lenovo Mobile Business Group, India had to say about the company’s performance in 2016:

“The Moto G franchise continues to be much loved and we witnessed an extremely high conversion from early Moto G buyers opting for the new Moto G 4th Generation. But, our real game changer and technological breakthrough was the Moto Z and Moto Mods series that redefined the evolutionary progress of the smartphone industry. The Moto Z and Moto Mods system is designed to provide connected, intelligent and mobile consumer experiences in a seamless fashion and the power to transform your (Moto Z) smartphone in a snap is revolutionary. We started with four Moto Mods and are continuously working with multiple partners to develop more Mods for smartphone users in 2017.”

What’s next?

2017 will be a crucial year for the company as it prepares to build upon the success of the G4 and Z range. It is pivotal for Lenovo to make sure that it retains the essence of the company while at the same time push new boundaries of design and innovation.

When the army are on the battlefield, the equipment that they carry and the weight of it is paramount. Most two way radios are one of two things, light and easily breakable, with limited power, meaning limited range or heavy and the opposite to the above, Robust and able to transmit at a lengthy distance. The current development for a 2 channel that’s able to receive and transmit voice and data is an interesting concept. This article, that can originally be found here, give you more of the story.  

Nearly two years after the award of the Rifleman Radio contract, I made an appeal for new thinking by both the defense acquisition corps and the defense industry that now bears repeating.

Twenty-two months ago, the need for the Rifleman Radio was obvious as it is today. It provides infantry units with a relatively small and lower cost software-defined radio capable of transmitting voice and data, such as maps, images and texts. The technology that defines this “workhorse” tactical radio was continuing to mature, resulting in today’s Rifleman Radio being far more reliable and capable than the LRIP-ordered radios from even three years ago.

This maturation process was being driven by ongoing investments in radio technology made by the defense industry, including Thales and Harris Corporation, the two companies selected by the Army to build the Rifleman Radio.

At that time, I noted that success in the Defense Department’s new “Non-Developmental Items” or NDI strategy for the Army’s HMS program would require three things:

  • People. Bringing the right people together from three key groups for meaningful engagement: those defining the capabilities; those acquiring the capability for the government and industry; and those who have to deliver the capability to the Warfighter.
  • Dialogue. Creating ethical opportunities for face-to-face discussions with industry (not RFI dialogues) about the state of technology innovation and what is feasible to provide in a reasonable time and at a reasonable price.
  • Strategy. Building a shared understanding that this new NDI marketplace for tactical radios that requires industry to invest their own money to develop products will be one that delivers greater and greater capabilities over time, in other words, iteratively.

Where are we now? 

The Army is currently working to develop requirements for a 2-channel variant of the Rifleman Radio, a significant step in the Rifleman’s continuing evolution. The fundamental 2-channel communications capability — whether handheld or manpack variants — represents the future of tactical communications.

Two-channel capabilities for the small-unit leader radio like the Rifleman will meet the Army’s evolving tactical communications needs, with its ability to receive and transmit voice and data simultaneously, passing data to and from command to the unit.

The 2-channel Rifleman Radio will provide new capabilities without adding weight from extra radios and batteries. In short, it will provide the capability of two radios without burdening troops with lugging around two radios.

Viewed from a technical perspective, however, a 2-channel handheld radio represents an exponential leap in terms of complexity — it bears no relationship to the notion of “fusing two 1-channel radios together.”

Even the 2-channel HMS Manpack represents a tremendous technological leap forward, though it came with fewer space, size, power and weight limitations than the much smaller handheld Rifleman undoubtedly will. In short, the 2-channel Rifleman Radio will be a tall mountain to climb.

The future Rifleman 2-channel

The 2-channel Rifleman is an achievable reality, however, and speaking for Harris, we’re already well on the way to delivering this capability. The U.S. Special Operations Command (SOF) Tactical Communications (STC) 2-channel handheld radio being developed by Harris for special operations forces is leading the way to this future.

The STC radios are able to operate in the harshest environments and are specially designed to meet rigorous requirements. The STCs are small, lightweight, multiband and multifunction, with multi-mission capability to enable SOF teams to communicate over multiple channels simultaneously.

The Harris STC will provide the ability to receive ISR full-motion video and signals-based threat information. These handheld radios also will have built-in backward interoperability to communicate over legacy networks, and will be upgradable to integrate new capabilities as requirements evolve.

Although the Army’s requirements are still coming together, the 2-channel Rifleman most likely will trade fewer features for less cost. That said, there are many technical attributes related to the 2-channel capability that are likely to be applied from the Harris STC to the next iteration of the Rifleman.

The important takeaway here is that the Army’s continued commitment to evolving tactical communications has led industry to sustain its investment in advancing capabilities — and that formula has brought the 2-channel handheld much closer to reality.

Whether it is the STC or 2-channel Rifleman, the coming wave of new communication capabilities are the result of persistent innovations in myriad radio components: chip design, software, battery life, power consumption and antennas, to name a few.

As I pointed out in January 2015, the development of the Rifleman Radio would represent just the first iteration in the Army’s modernization of tactical radios ― a commitment that would deliver even more revolutionary capabilities over the next decade. But this will only happen if the Army maintains its end of the bargain by assuring industry that ongoing investments would be rewarded with purchases of the end products.

If BBP 1.0, 2.0 and 3.0 continue to be nurtured and “take root,” these radio technology capabilities will continue to evolve with each measured investment making possible continuing progress. Such an active NDI marketplace will ensure industry remains committed to R&D — and the beneficiary of this healthy dynamic is the warfighter.

Radio frequency (often abbreviated as, RF), can be described as any frequency within the electromagnetic spectrum with radio wave propagation that lie in the range extending from about 3 kHz to 300 GHz; this includes the frequencies that are used for communications or the radar signals. That said, you should know that RF generally refers to electrical rather than the mechanical oscillations.

RF communication utilizes radio waves rather than wires to exchange signals, and this is where the term “wireless communication,” comes from. RF modules generally use frequencies to distinguish the different radio signals, therefore, in order for the RF modules to communicate, they have to be operating on the same exact frequency. That said, you should know that radio frequency is normally measured in units known as hertz (abbreviated as Hz), which represent number of cycles/second when the radio wave(s) is transmitted. 1 hertz (Hz) equals 1 cycle/second, and 1 megahertz (abbreviated as, MHz) equals 1 million cycles/second.

A radio frequency (RF) signal basically refers to the wireless electromagnetic signal that’s utilized as a form of communication, when talking about wireless electronics. As mentioned earlier, radio waves are a type of electromagnetic radiation which have identified radio frequencies which usually range from about 3Hz to 300 GHz. Not every radio wave is the same; they can be small or big, or they can be far apart or close together. On the radio stations we normally listen to, every station uses waves which are on a slightly different frequency from the other stations. Whenever you happen to switch from one radio station to another, your radio picks up and then plays waves of that particular frequency.

Frequency normally refers to the oscillation rate of the radio waves. It can also refer to how close together or far apart the waves are. When the radio waves are too far apart, that is known as low frequency, and when the radio waves are close together, that is known as high frequency. That said, you should know that radio frequency propagation happens at speed of light, and doesn’t need any medium (such as air) in order for it to travel. Radio frequency waves occur naturally from lightning, the sun flares, and even from stars which radiate radio frequency waves as the get older. However, people usually communicate with man made radio waves which oscillate at various select frequencies.

The man made radio frequency waves are produced by oscillating current for a certain number of times, and radiating it off the conductor (which is referred to as the antenna), into an empty space (this is the space that’s occupied by air and not the outer space), as electromagnetic radio waves. The RF signals are received and sent using conductors via the phenomenon that’s called the skin effect, where radio frequency current latches itself and then flows through the conductors’ surface; this effect is actually the basis and the core of radio technology.

The best thing about RF communication, is that it’s omnipresent (that is to mean it’s all around us). It plays a crucial role in many of the communications systems which we depend on a daily basis, such as fire and police radio systems, TV and radio broadcasts, and satellite communications. Cordless phones, cellphones, Wireless internet (Wi Fi), and Bluetooth also operate in the radio frequency spectrum. In addition to that, there are other appliances outside of the communications field that use RF. They include; microwave ovens, garage door openers, among others. Some wireless devices such as TV remote controls, cordless computer mice, computer keyboards, and even 2 way radios also operate using RF frequency.

Two way radios are based on the RF frequency and they perform group communication using minimum radio frequency channel resources. This is to mean that if all the users are in the same location or area (most of the time), you will only need a single channel resource in order to talk to them. By using RF, two way radios have the capability of facilitating “one to many” group communication (which is also known as a group call), very efficiently. By efficient, I mean that 1 user can communicate/talk to 1, 5, 10, 100 or even 1000’s of users at a go. The 2 way radio user doesn’t need to keep on repeating the same message if he/she needs to convey to many users.

We are very excited about 5G, we have already reported on how the UK emergency services are moving over to a LTE network, and inevitably 5G is the next step for better, faster and more capable communications.  Not planned to be deployed until the next decade, we believe that 5G will allow us to communicate better with our Walkie talkies. The original article can be found here.

With faster and more reliable connections, we look at what the next generation of communications could mean for business

From smart cities to the internet of things (IoT), virtually every aspect of the modern world is becoming closely connected.

The extent to which we rely on our devices and the exchange of information means new systems are needed that not only handle far greater bandwidth, but that are capable of being deployed to cover areas that were previously unreachable.

The potential benefits for business are huge, with faster and more reliable connectivity not only enhancing how firms interact with customers and each other, but also lending itself to greater flexible working among staff.

The arrival of 5G

One development that many industry observers believe could be revolutionary is 5G. Following on from 4G, the fifth-generation mobile network is in its early stages of development and is expected to be rolled out between 2020–25.

Any tech that contributes towards the next phase of mobile connectivity is covered by the term 5G. And although there are still no set standards or specifications, the GSMA – a trade body that represents global mobile operators – has outlined eight key criteria, stipulating minimum requirements for speed, capacity and energy in order for something to be considered 5G.

According to Ofcom, once operational 5G could provide between 10–50 Gbps (gigabit per seconds) in download speeds (as compared to the 5–12 Gbps of 4G), and although most experts expect it to be at the lower end of the range, that would still mean you could download an HD movie in seconds.

But rather than simply being faster than the current 4G, it will also allow more devices to access the web – an essential requirement if the IoT is to take off – meaning it could be transformative for business.

Raj Sivalingam, executive director of telecoms for techUK, the trade association for the tech sector, says: “The potential of the IoT, particularly in the enterprise environment, has been hugely debated but its impact is almost certainly still undervalued.

“Mass deployment across sectors will boost efficiency and safety with pre-emptive fault correction; enable automatic reporting of accidents and allow real-time asset tracking, reducing crime and increasing productivity, to name just a few benefits.”

One potential bottleneck for 5G is spectrum availability – or lack of it. Radio frequencies for both 3G and 4G are already overcrowded. The provision of a new bandwidth will require widespread cooperation between operators, manufacturers and governments.

Infrastructure is also an issue, says Sivalingam. “Making the leap to 5G mobile services and getting more fibre into the fixed telecommunications networks will require substantial amounts of investment.

“We need the government and industry stakeholders to work to shift the UK from good levels of connectivity to great levels so that we continue to attract investors and startups, and to foster innovation from within the UK.”

Cognitive radio

One possible solution is cognitive radio. An adaptive radio and network technology, it can sense and respond to its operating environment and automatically tune itself to the best available frequencies, this makes it more reliable in extreme locations where signals are weak, potentially providing dependable, robust connections that are not hampered by interference or geography.

Finland-based KNL Networks has developed a system using the technology that uses short wave radio to transmit internet access to sites in remote locations ranging from oil rigs to polar research stations. KNL Networks CEO Toni Linden says: “We can provide similar connectivity to those from satellites but with a terrestrial radio system. Our radios receive the whole spectrum all the time, so rather than scanning, real-time broadband receiving is going on. Thus we can see and measure everything that’s going on in the spectrum and we can maintain the network connectivity that way.”

The tech opens up the possibility of providing seamless connectivity anywhere, giving business reliable online access to markets in parts of the world that have otherwise been unreachable. It could also enable media and other companies to broadcast without the need for expensive satellites.

Quantum key distribution

It’s not just data transmission, speeds and connectivity that pose challenges in the future, but the safety of that data too. Cybercrime is ranked alongside terrorism as among the most serious threats to the UK [pdf], and with data now the lifeblood of modern business, securing that data is of paramount concern. One technology that could provide the answer is quantum communications.

Conventional encryption relies on sending a decryption key alongside your secret data. The receiver then uses that key to decode your secret information. But problems arise because hackers can also copy this key and steal your data.

Quantum key distribution (QKD) is different because it encodes this key on light particles called photons, and an underlying principle of quantum mechanics means that a hacker trying to read or copy such a key would automatically alter its state, effectively leaving a hacker fingerprint so the sender and receiver know their information security had been breached.

China recently launched a quantum satellite to further research into this technology, with the hope of developing an uncrackable communications network.

In the UK, the Quantum Communications Hub is part of a national network of four hubs led by the universities of Birmingham, Glasgow, Oxford and York. Director Tim Spiller says: “We are developing quantum communications technologies along a number of different directions, notably short-range free space QKD, where the transmitter could be in future mobile phones, and chip-to-chip QKD through optical fibre, where the chips could be in future computers and other devices.”

With two thirds of British business falling victim to cybercrime in the past year the need for better encryption is clear.

Several companies currently offer commercial quantum key distribution systems include ID Quantique, MagiQ Technologies, QuintessenceLabs, SeQureNet and Toshiba, although its high cost and limited range means mainly banks and governments are its main users, with mainstream adoption still some way off.

Spiller added: “Certainly it would be desirable to improve the size, weight, power and cost points of current technologies and our work in the hub and elsewhere is addressing all these factors.”

Paul Lee, head of technology, media, and telecommunications research at Deloitte, highlighted a number of improvements which he expected to see coming down the line, including improved mobile antennae and base stations, as well as improvements to fixed networks such as G.fast that would enable copper cable to operate at much higher speeds.

“As they get steadily faster, new services emerge to exploit these greater speeds, which then requires the deployment of even faster networks. This tail chasing has been going on for decades and won’t stop in 2017.”

Motorola solutions are a company well known for their robust two way radios and for building world class communication structures. Improving on the current TETRA system with an IP dispatch console and piloting the WAVE system, that allows a phone app to connect to the radio system, for communicating of site. You can read more about what Motorola are doing for Munich below and you can find the original article here.

Motorola Solutions has received an order to implement a comprehensive update and extension of its existing TETRA digital two-way radio system at Munich Airport.

The newly modernized communications infrastructure ensures greater connectivity, interoperability and collaboration between various business and operational functions at Germany’s second largest airport. Motorola Solutions will also provide services for ensuring smooth operations.

Within the framework of the TETRA radio network refresh, Motorola Solutions is equipping the airport with a new MCC 7500 IP Dispatch Console. The comprehensive, scalable solution enhances the IP architecture to ensure optimum call set up and availability. It will also allow Munich Airport to expand its communications infrastructure in the future without interrupting existing services. As well as this, Motorola Solutions will implement two TETRA base stations for improved TETRA radio coverage in the terminal buildings.

Alongside the improvements to the TETRA system, the airport has started a pilot project for the potential introduction of Motorola Solutions’ broadband push-to-talk (PTT) platform WAVE. The goal of the installation is to ensure that airport staff can communicate, no matter which device or infrastructure is being used. The powerful PTT solution WAVE™ Work Group Communications provides airport authorities with secure and reliable communications beyond TETRA radio – including broadband devices and networks – to enable greater workforce connectivity, interoperability and collaboration. WAVE connects the TETRA system used by administrative staff with service management employees who join the broadband platform via smartphones, computers, other radios or telephones, meaning that staff across the airport can communicate with one another from virtually any location.

“We have been working with Motorola Solutions’ TETRA two-way digital radio system since 2007,” said Michael Zaddach, head of the IT service division at Flughafen München GmbH. “The update of our TETRA infrastructure enables us to further improve our communications in airport operations and make our processes even more efficient.”

“We are collaborating closely with Munich Airport to provide a future-proof TETRA digital two-way radio network,” said Klaus-Dieter Drossel, sales director for key accounts, Motorola Solutions Germany GmbH. “We are also pleased that Munich Airport is testing our broadband push-to-talk platform WAVE, and we are certain that it will enable airport staff to work together more closely, no matter which device or network they use.”

Theoretically, you can use an unlimited amount of walkie-talkies on the same channel (although in practice you might experience a few problems if you took that suggestion literally). Basically, there isn’t really a set limit. You could use as many as you like provided they are set up correctly. Anybody set to the right channel and in range at the time of transmission would then be able to pick up the signal and respond to it.

Most radios have access to 8 channels. These channels each have 38 separate ‘identification tones’. The user sets his/her channel up with the desired tone and then only other users who know the channel/tone will be able to hear the transmissions. As a result, there are, in any given area, about 304 different combinations, so signal interference is unlikely to affect you.

Please do not interpret this answer as saying that your radio has access to 304 possible channels. It does not. It will likely only have access to 8. Some less reputable manufacturers tend to falsely imply access to 304 channels; this is simply not the case. You will have access to 304 possible tone/channel combinations, that’s all.

To better explain the CTCSS codes and how they work; we’ll include a little information from Amherst.co.uk’s FAQ page.

“CTCSS stands for “Continuous Tone Coded Squelch System”. These codes are also often called “Privacy codes” If a CTCSS tone is selected; a CTCSS sub-audible tone is transmitted along with the regular voice audio by the transmitting radio. The receiving radio, set to the same CTCSS tone, will only receive audio if it contains that sub-tone. Interference from other users on the same frequency is therefore rejected (unless they are also on the same sub-tone). This is a way of allowing groups of users of walkie-talkies on the same channel to avoid hearing messages from other nearby users”.

So, in conclusion, you can probably use as many walkie-talkies as you like on the same channel. As long as the units in question are of the same type (either VHF or UHF) and have the same CTCSS setup, then you simply shouldn’t have a problem. You also shouldn’t suffer from signal interference due to other users (although you may still experience signal loss/interference/degradation from other sources). We have talked about combating signal loss elsewhere, so please see the other questions if you have any problems in this area.

Apparently using a two way radio during an American football game is frowned upon over in the good old US of A, This article is about a game between the Giants and the Cowboys. During a Game the coaching staff and Quarterback are not allowed to communicate if there is 15 seconds or less on the clock, this rule might have been broken with the use of a walkie talkie.

The NFL is investigating the Giants’ potentially rule-breaking use of a two-way radio during the team’s recent 10-7 win over the Dallas Cowboys.

The use of a two-way radio by a coach during a game is strictly against league rules, according to ESPN.

In the fourth quarter of the Cowboys game, Giants head coach Ben McAdoo was spotted using a walkie-talkie to communicate play calls with Eli Manning after his headset malfunctioned.

In the fourth quarter of the game, Giants head coach Ben McAdoo was spotted using a walkie-talkie to communicate play calls with Eli Manning after his headset malfunctioned.

The Cowboys issued a formal complaint to the league over the radio use, but the NFL’s investigation was already underway by the time Dallas contacted them.

The NFL has a rule against coaches using two-way handheld radios because the league cannot control when both parties are communicating.

A coach using a walkie-talkie makes it harder for the NFL to monitor a league rule that states communication from the sideline to the quarterback must end when 15 seconds are left on the play clock.

With headsets, the NFL has the power to shut off communication at will with a “cutoff switch operator,” ESPN reported.

The Giants had no comment when reached Thursday night.

McAdoo used the walkie talkie in question, however, for about four or five plays on the Giants’ fourth-quarter drive that ended in an Eli Manning interception on a pass intended for Victor Cruz.

McAdoo’s normal equipment malfunctioned and as the Giants worked to fix it, the coach was handed the walkie talkie temporarily because its signal was reaching Manning’s helmet.

As the Giants worked to correct McAdoo’s equipment, Odell Beckham Jr. could be seen running to the sideline to bring plays back to the huddle and Manning was heading over to the sideline, as well.

There is no evidence in reviewing the game film that demonstrates McAdoo was on the walkie talkie for longer than the allowed 15 seconds of communication with his quarterback.

There is also, of course, no evidence that the Giants gained any advantage even if he was. The drive ended in a turnover and the Giants’ offense stunk most of the night.

It is surprising how in a crowded, noisy environment you can still create your small world. This is one of the most amazing changes that have been made by headphones. Small devices with a big impact on the world are the only way to describe headphones. In the past, the only way to listen to music was through devices that allowed everyone to listen to music at the same time. With the introduction of headphones, you don’t have to bother everyone with your music; you can create your space and enjoy listening to what you like directly to your ears.

How headphones have changed over time

Early headphones were mainly used for communication purposes. The birth of headphones in early 19th century was purely for communication and professional uses. It is strange how the creator of headphones Nathaniel Baldwin didn’t have the musical concept in mind. The uses of headphones at this time were purely for professional uses by people in the army and also church coordination.

Discovery of stereo phones for music was a big break in the mid-19th century, the whole perspective of headphones changed from professional use and they were given a musical touch. The musical evolution changed the concept of headphones, and this gave birth to the stereo phone technology to cater for musical fanatics. This was when headphones specifically for music were created, but they were expensive.

Light weight portable headphones were discovered in the 1980s there was a big break after everything went mobile. The headphones now become lighter, and you could see youngsters carrying them around. The growth of the pop culture at this time might have had a huge impact on how people wanted to listen to their music and this made headphones grow more. The sound quality becomes better at this time.

Modern fashion statement headphones are now common to bring out personality and social standards. The headphones that we have now are bringing the fashion statement in mind. The unique design and the big brand names like Beat by Dre are bringing a new perspective on the way we view headphones. The technological advancement is sound quality is now improving due to latest technological innovations.

Benefits of headphones in the modern world

Good sound quality and faithfulness is one of the main benefits of headphones. We all agree listening to music through headphones feels good compared to listening through loudspeakers. The reason for this is quite listening simply. Music from headphones has no interference from external forces and especially if you are listening to music through quality headphones.

The concentration at work is now better with headphones. With the use of headphones, it is now possible to get peace of mind and keep up concentration whilst working. It is surprising how music takes us to a new world where we can be able to reflect and focus on the work we are doing. This is the reason why you will find people working in jobs that need a high level of concentration using headphones all the time.

Peace of mind and calming stress is a major reason why many people use headphones. Music is therapeutic, and it works wonders in relieving stress and restoring peace of mind. Listening to music through external speakers is good for entertainment but not necessarily for healing. There is something special about listening to music through headphones because it brings calmness and brings back peace of mind.

Privacy is one thing that many people seek in the crowded and noisy world. If you want to maintain privacy, then you can easily escape in your headphones and get the privacy that you need. People around you will understand that you need privacy and allow you to have your solitude.

Who uses headphones?

The uses of headphones are now limitless, and they go beyond just for the sake of entertainment and communication purposes.

Music lovers get lost in their headphones for hours listening to music without interrupting the rest of the world with the type of music that they love. Using headphones, music lovers can get the sound effect that they want from the headphones through sound effect settings.

Transcribers who translate audio content into text need headphones to be able to listen to what they are typing. This is one of the most common professional use of headphones. Other people like pilots, recording artists and also the military use headphones in their job.

This is an interesting article debating the different types of communication that can be used over a long distance, and as they distance moves further and further, the different types of communication drop off or become part of an infrastructure. As engineers battle with this problem, knowledge of how radio frequencies and applications becomes paramount.

As offshore windfarms are built further and further from land, alternatives to conventional VHF communications are going to be required

A cornerstone of any major project is clear communication between all parties. As we move windfarm construction further offshore, maintaining efficient voice and data communications becomes essential. With many projects now being constructed beyond the range of VHF radio and cellular telephone, such as a Gemini or Dudgeon offshore windfarms, crew transfer vessel (CTV) operators and their clients are experiencing challenges achieving practical and affordable offshore communications. My experience on two far offshore projects in the last 15 months has shown that creative thinking can work together with existing equipment such as TETRA radio to reduce the risks and stress that poor communications can generate.

Communication solutions on offshore windfarms depend on the phase that the operation is in, the size of the project and the distance from shore. Many smaller, older windfarms rely on VHF radios to communicate between shore and vessel and shore/vessel and work team on the turbines. However, VHF is limited in range being a line-of-sight system, and the signal has trouble penetrating structures such as wind turbines due to the Faraday cage effect. Conventional cellular telephone coverage is also possible on nearshore sites, with some windfarms installing a cellular mast within the windfarm. Vessels at anchor off the Dutch port of IJmuiden can thank the windfarm industry for good connection when waiting for a pilot if they have contracts with the provider KPN.

When moving further offshore, luxuries such as a cellular mast will not be installed during the construction phase, and it is most likely that VHF radios will not be sufficient. It is common for the developer to install a TETRA radio network – similar to those used by national emergency response services such as police and fire departments.

TETRA, or terrestrial trunked radio as it is properly termed, is a secure network allowing one-to-one, one-to-many and many-to-many communications. This means that the marine controller can speak directly and privately to one party or to the entire offshore spread depending on what is needed. It transmits on a lower frequency than VHF so covers a greater range. This still is not enough to cover the distances experienced on far offshore windfarms. If multiple base stations are used, each base station can then automatically rebroadcast a message thus expanding the network coverage. On a recent construction project, it was found that there were communications blackspots in the area of the sea passage from the base port to the site. This was later eliminated by fitting full base station units rather than just handheld transceivers on the CTVs. The CTVs then became vital links in the communications network and ensured the blackspots were reduced or eliminated altogether.

TETRA has many other advantages, including the ability to penetrate the tower of a wind turbine, and calls are not dropped when moving between base station carriers due to the network configuration. This is especially important if vessel-carried base stations are relaying far offshore. The network is also secure, which ensures that commercially sensitive information cannot be intercepted. With the one-to-one mode, it also means that managers can have detailed conversations on sensitive subjects.

However, anecdotal information received from vessel crews in the field appear to indicate that TETRA, although a good system, is not foolproof. One vessel master reported that, after 15 months on site, they still had blackspots with TETRA and sometimes have to use the cell phone application WhatsApp to request that turbines be started or stopped so that he can land a team.

TETRA does not solve the operational problems experienced by vessel-operating companies who require frequent voice and data communication with the CTVs to ensure a smooth delivery of service. As most sites far offshore are outside of cell phone coverage and clients demand that daily reports are issued on time, creativity is needed. There is a simple solution that could solve all of the communication problems far offshore – installing VSAT satellite communications on each CTV, which allows instant telephone and data transfer.

However, the practicalities of chartering in today’s windfarm industry eliminates this option, as the client will not want to pay for installation and operation, and a vessel owner cannot afford such a luxury. Charterers therefore need to make a decision: either they assume responsibility and the costs for practical workable satellite communications on their vessels or look for practical alternative solutions to deliver what is needed far offshore.

One practical solution to maintain communications between the marine co-ordination centre and vessels is to step back a generation and use medium frequency/high frequency single side band radios, which are common equipment on larger CTVs and is standard on service operation vessels (SOVs) or installation vessels.

When used in conjunction with the digital selective calling (DSC) function of the GMDSS standard, voice communications can be maintained at long distance without operating cost. Unfortunately, current guidance for the marine co-ordination in windfarms as found in the G9 Good practice guideline: The safe management of small service vessels used in the offshore wind industry does not yet consider marine co-ordination and communications in far offshore windfarms.

Another practical solution to improve data communication is to install powerful WiFi antennas on the decks of SOVs and other major offshore assets to allow CTVs to have internet access when they are in close proximity. CTVs can then download passenger manifests and weather reports and upload the daily progress report and synchronise planned maintenance and email systems.

CTVs spend considerable time in close proximity to the SOV during passenger transfer, bunkering or waiting for the next assignment, and it is relatively easy to set up the computers to connect and synchronise without operator input, thus reducing the risk of distraction. SOVs should be designed with space for CTV crews to use as a secure office so that laptops can be left connected to the network. In this way, crews can have two computers and prepare work when on shift, transfer via a data stick and upload when they go off shift.

One of the most effective tools that we have identified is WhatsApp, which seems to require very low signal strength to connect and transfer brief messages. On recent projects, we have found that most vessel/office communication occurs in this medium, including fault finding and incident reporting and investigation. Crews have found it quicker to video a CCTV system playback and send via WhatsApp than download the CCTV video and send it via a file transfer service. As synchronising an electronic planned maintenance system offshore is very time consuming, our superintendents have taken to sending the worklists via WhatsApp to the vessels who then confirm back with text or images when a job is complete. The superintendent then does the PMS administration from their office with the advantage of high speed network connections. Experience with WhatsApp has led me to believe that agile, low data applications will form part of the future of offshore communication.

Far offshore projects have moved from planning and dreaming to reality. However, effective and cost-efficient communication solutions have not moved with them. Like most challenges with far offshore windfarms, there is no single solution, but experience has shown that, with creativity and flexibility, projects can communicate with their teams and operators can manage their vessels.

Better equipment earlier on in the construction phase, such as MF/HF radios in the MCC and on the vessels, TERA base stations on the vessels and open deck WiFi on construction assets will all assist in improving safety and reducing stress while ensuring that unnecessary costs are not incurred.

VR is the Buzz word for this year, every technology company clambering to get their headset out on to the market. Much of the market needs to catch-up though, the power of home computing needs to improve and removing the inevitable extra cabling and wires that come with current headsets. Luckily this article is about the future technology of VR headsets, see what we can expect as this technology grows.

If you want to use one of today’s major VR headsets, whether the Oculus Rift, the HTC Vive, or the PS VR, you have to accept the fact that there will be an illusion-shattering cable that tethers you to the small supercomputer that’s powering your virtual world.

But researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) may have a solution in MoVr, a wireless virtual reality system. Instead of using Wi-Fi or Bluetooth to transmit data, the research team’s MoVR system uses high-frequency millimeter wave radio to stream data from a computer to a headset wirelessly at dramatically faster speeds than traditional technology.

There have been a variety of approaches to solving this problem already. Smartphone-based headsets such as Google’s Daydream View and Samsung’s Gear VR allow for untethered VR by simply offloading the computational work directly to a phone inside the headset. Or the entire idea of VR backpacks, which allow for a more mobile VR experience by building a computer that’s more easily carried. But there are still a lot of limitations to either of these solutions.

THE MOVR PROTOTYPE SIDESTEPS TETHERED VR ISSUES

Latency is the whole reason a wireless solution hasn’t worked so far. VR is especially latency-sensitive, along with the huge bandwidth requirements that VR needs to display the level of high-resolution video required for virtual reality to work. But the MIT team claims that the millimeter wave signals can transmit fast enough to make a wireless VR headset feasible.

The issue with using millimeter wave technology is that the signal needs a direct line of sight, and fares poorly when it encounters any obstacles. MoVR gets around this by working as a programmable mirror that can direct the direction of the signal to the headset even while it’s moving to always make sure the signal is transmitting directly to the headset’s receivers.

For now, the MoVR is simply a prototype, with the team hoping to further shrink down the system to allow for multiple wireless headsets in one room without encountering signal interference. But even as a proof-of-concept, it’s an interesting perspective on how virtual reality could one day work.

Smart earpieces are the next frontier for the smart generation, we have all seen the earpiece that can translate instantly But that is just the start, as we can see from this article about this Xperia Ear wireless earpiece, it updates you from your phone when you put it in your ear. It won’t be long before we won’t need a smart phone everything will be in our ear.

Sony has revealed its ‘smart personal assistant’ that include a bluetooth earpiece will go on sale in November.

At the IFA show in Berlin today, the firm confirmed it will launch this November ‘starting in select markets,’ although its price has still not been revealed.

The Xperia Ear wireless earpiece can update you with any missed calls or messages as soon as you slot it into your ear.

The firm also showed off a Xperia Agent, a robot measuring just over one foot tall, that also works as a PA.

‘It will navigate you to where you want to go and make your life eye-free and hands-free,’ said Sony Mobile’s President and boss, Hiroki Totoki of the ‘her’ earpiece when it was unveiled at the MWC show earlier in the year.

‘It is also powered by Sony’s voice technology and will respond to a number of commands.’

The firm says the smart earpiece ‘is a next-generation wireless ear-piece that brings a new way of communicating, without compromising on enjoying the world around you.’

It reads users information such as your schedule, weather and the latest news to keep you up-to-date on the go.

Powered by Sony’s voice technology, it responds to verbal commands, so you can ask it to make a call, perform an internet search, dictate a message or navigate to a certain location.

It connects to an Android smartphone via NFC or Bluetooth and talks to a host application, where you can customise settings, including the info you need when you first connect in the morning, touch commands and app notifications.

‘Its lightweight and comfortable soft silicone ear-bud is built for continuous wear, with IPX2 water-protection and all-day battery life3,’ Sony said.

It’s available in Graphite Black and the innovative case doubles as a charger, so you can simply pop it in when you need to recharge.

It also unveiled the Xperia Eye, a wearable camera that acts as your personal sidekick, capturing everyday life moments with a 360 degree wide-angle lens.

Unveiled at Mobile World Congress (MWC) in Barcelona, the Xperia Eye can be attached to clothing or worn around the neck.

It forms part of a suite of connected gadgets designed to free people up from their phones.

Sony said the Xperia Eye is ‘a vision for a personalised assistant’ and joins three other smart gadgets that are connected to a Sony smartphone that acts as a hub, feeding information to them such as notifications.

These are Xperia Agent, Xperia Project and Xperia Ear.

Xperia Agent is a security camera-style device which acts as a home monitoring system, keeping an eye on what’s going on around it and projecting notifications fed to it from a Sony smartphone onto surfaces around it.

‘It will provide you with useful information, communication assistance and home appliance controls,’ Sony said.

Xperia Project projects an interactive interface onto any clear surface, meaning you can manipulate images, webpages and screens you would usually find on your smartphone, onto a hard surface.

Sony claims this projected image will respond to touch, voice and gestures just as someone would interact with your smartphone screen.

The Xperia Ear is a wireless earpiece that will update you with any missed calls or messages as soon as you slot it into your ear.

‘It will navigate you to where you want to go and make your life eye-free and hands-free,’ said Sony Mobile’s President and boss, Hiroki Totoki.

‘It is also powered by Sony’s voice technology and will respond to a number of commands.’

The wearable camera is the first time Sony has shrunk its image sensing and camera technology into such a small device.

Hytera have a wide range of radios in their catalogue now, and this is a new addition. The PD98X is for the professional communicator, a radio that has more added extras than a lot of smart phones. A couple of questions we would like to ask are:

We are seeing a new era in communications at the moment, the move from tetra and RF to the mobile network. The uk’s emergency services will be moved over to EE’s ESN system slowly until 2020 using Motorola kit designed particularly for the technology. The natural evolution is 5G, which we won’t see for many years, but Ericsson have taken the baton and are running with it.

  • World’s first commercial 5G New Radio (NR) radio for massive MIMO and Multi-user MIMO coming in 2017
  • New additions to Ericsson Radio System address key requirements of 5G, in today’s networks
  • Pioneering Industrialized Network Rollout Services solution facilitates complete rollout from configuration to verification in a single visit

Ericsson (NASDAQ:ERIC) is commercializing the world’s first 5G NR radio for massive MIMO, with the first deployments coming in 2017. Together with the Ericsson 5G Plug-Ins announced in June and Ericsson’s already commercially available Radio System Baseband 5216, which currently powers Ericsson’s award-winning Radio Test Bed, Ericsson is first to deliver all components of a 5G access network.

Tom Keathley, senior vice president, Wireless Network Architecture and Design, AT&T, says: “As we accelerate toward 5G, it’s beneficial to have a flexible radio platform that can be deployed not only for LTE, but also versions of future 5G NR standards.”

AIR 6468 combines advanced antennas with a large number of steerable ports to enable 5G technologies of beamforming, Massive MIMO and — building on that — Multi-user MIMO, initialized as MU-MIMO. These capabilities improve user experience while enhancing the capacity and coverage of the network and reducing interference. The new radio provides LTE support as well, so it is applicable in today’s networks.

Huang Yuhong, Deputy Head, China Mobile Research Institute (CMRI), says: “Massive-MIMO, also known as 3D MIMO, is an important milestone in China Mobile’s technology roadmap from 4G to 5G. We are very happy that Ericsson’s new radio product is coming to market soon to meet our needs and enable us to integrate 5G technologies into our existing networks.”

A host of new additions to the Ericsson Radio System are also coming that address key 5G requirements, in today’s networks.

Daniel Staub, Head of Joint Mobile Group, Swisscom, says: “On the road to 5G, we will continue to invest in LTE advancements that will become part of our 5G networks. For us, it is key that Ericsson has chosen to focus on advances that will support us in this evolution. These enhancements will further improve the customer experience.”

Additional new Ericsson Radio System gear addresses 5G concepts

  • Three new radios support Gigabit speeds for LTE and provide further flexibility in design: Radio 4407 and Radio 4412 enable 4×4 MIMO in one radio unit for FDD and TDD mode respectively, and Radio 8808 for advanced TDD beamforming applications
  • Addressing both the need for unlicensed spectrum options and the growing emphasis on small cells is the Radio 2205, a micro solution on unlicensed spectrum that is fully integrated in Ericsson Radio System, using the same baseband and network management
  • Two new baseband units support the growing need for densification: the outdoor micro Baseband 6502 and macro Baseband 6303 with Ericsson Rail System mounting for flexible site builds
  • Addressing interference issues in dense builds, Baseband P614 enables new band activation on challenging sites by mitigating Passive Inter Modulation, referred to as PIM mitigation, from static and dynamic sources both inside and outside the antenna system
  • Spectrum optimization is a growing need and Uplink Spectrum Analyzer is an Ericsson-unique software solution to remotely identify external interference without the need for costly measurement equipment and site visits
  • Exclusive to Ericsson is instant power sharing, used in the wideband Radio 2242. This capability allows power to be instantly shared between carriers, standards and bands, optimizing the use of radio resources
  • Cloud RAN will be an important 5G network architecture and Baseband C608 provides high-performance switching in Elastic RAN deployments

Peter Jarich, Vice President, Consumer and Infrastructure Services, Current Analysis, says: “Mobile operators, today, are clearly focused on the race to 5G commercialization, while also continuing to invest in their existing LTE networks. With a new 5G radio and LTE offerings which echo key 5G concepts – small cells, licensed-unlicensed band combinations, Cloud RAN, network densification, spectrum optimization – Ericsson’s new portfolio additions and Ericsson Radio System innovations provide a compelling way forward.”

To support new network builds, Ericsson has created the industry’s first Industrialized Network Rollout Services solution. The Network Deployment Delivery Platform coupled with Ericsson’s pioneering process facilitates the complete configuration, installation, integration, shakedown and handover of a fully verified site, ready in a single site visit.

Arun Bansal, Head of Business Unit Network Products, Ericsson, says: “Ericsson has driven innovation in every generation of mobile technology and now we are set to over-deliver on an aggressive promise. We are introducing the new hardware that 5G Plug-Ins, announced in June, will run on, so that the first operators can start to deploy 5G infrastructure.  And, we are also launching innovations that improve both the performance and efficiency of today’s networks using concepts that will evolve into 5G.”

This article is the transcript of an interview with Igal Golva, CEO of Axum earphones, wireless earphones with secure fittings, designed for people doing exercise. A really interesting article about why these earphones are different to others on the market and what their plans are for the future of the company.

Mobile audio has always been a difficult balancing act. The need for great audio on the go has never been more prevalent. With smartphones now a staple for most people’s daily commute, exercise and fitness, the need for an audio solution that can be portable while still sounding good is the holy grail.

Apple, with the iPhone 7 has also forced people’s hands. The headphones they used to use are no longer as easy to pull out and plug in without the use of a dongle. This is where Bluetooth audio options come into play, and where the Axum wireless headphones are planning to make a splash. Currently on Indiegogo, the Axum are aiming to give people great audio, while ensuring they maintain that mobile, ultraportable feel. Currently at 528% funded, the Axum is proving to be a product many people want to get their hands on. We had a chance to talk to Igal Golvan, CEO at Axum, about what the headphones can do for audio and fitness and how they hope to change the way people view Bluetooth audio.

Axum: The Future of Wireless Audio 1

CGMagazine: Could you tell us a little about what Axum does and how these new headphones stand above the competition?

Igal Golvan: First of all, we not only offer four hours playtime (while others offer 1.5-2 hours) you can also get an additional four with the portable charging case. We achieved it by eliminating any unnecessary features. We are aiming to reach fitness junkies like us that need three things: fit, sound and battery life.

Our designers made a unique design that will fit you during the most extreme sport activities. In the last months all we did was test the earphones in every sport activity you can imagine .This included cycling, running, CrossFit , snowboarding and even sky diving .

The issue with True Wireless Earbuds is that all our competitors see this product as the latest technology in the headphones industry and as such they’ve aimed the technology at early adopters. Unlike them we understand the real potential of the product to become the mainstream earbuds of athletes, as the lack of cables is something so comfortable no one can even imagine, only when doing sport activities and listening to Axum earphones will you really understand the definition of freedom!

Axum: The Future of Wireless Audio 2

CGM: Could you go over what M-voiD® sound technology brings to the table?

IG: Sure. M-voiD stands for Multidisciplinary virtually optimized industrial Design. It’s a technology for the realistic simulation of audio systems using CAD data. It is a sophisticated technology that paves the way to reproduce outstanding sound performance to let consumers discover that earphones deliver the emotions and excitement comparable with a concert.

Realistic and predictive simulations by means of a fully coupled multiphysical electrical-mechanical-acoustical simulation model are the heart and driving backbone of M-voiD® technology. The major advantage of M-voiD® is that acoustic problems can be identified and resolved in the virtual domain before any prototype is being built.

Sound characteristics are virtually measurable and assessable and can be optimized on the virtual model. It is not just limited to the graphical reproduction. M-voiD® listens to the virtual sound of the earphone already on the computer by means of a special reproduction technique (called auralization), enabling improved sound. Bottom line, while even the largest companies out there can test 100 or maybe 10,000 prototypes to check and improve the sound quality before releasing the final product, we had the ability to test sound quality from over 10 million prototypes.

Besides that, Konzept-X also helped us with the driver design itself to maximize the results after we’ve changed the internal design.

Axum: The Future of Wireless Audio 3

CGM: With your Indigogo doing so well, do you foresee this will delay the final release?

IG: Exactly the opposite. We planned to wait until the funding period is over to head into mass production, but now that we understand the demand we’ll start doing it ASAP.

CGM: Why the choice to go with Indigogo over an option such as Kickstarter?

IG: We thought about KS, however the Indiegogo team was much more supportive and offered lots of relevant information on how to succeed with crowdfunding . We are product people and don’t understand crowdfunding, so a supportive team was something very important for us.

CGM: Do you plan to offer a retail version of these headphones?

IG: Of course, but first we’ll ship everything to our backers and then we’ll think about retail.

CGM: For the gamer on the go, will these offer anything beyond what is already in the wild?

IG: The perfect fit of Axum earbuds is something like you’ve never experienced before, you can see the bulky design of other brands such as Samsung and Motorola The last thing you want to do is wear those gigantic things all day long.

Axum: The Future of Wireless Audio 4

CGM: How do you think these headphones will do with the fitness crowd beyond just the music listener?

IG: We believe that beside the sound quality, the fit and comfort is something they’ll be addicted to. We noticed the reaction of the people while testing them out in the gym and we guarantee that once you try Axum earbuds you’ll never be able to use wires again!

CGM: Are there any obstacles you will need to overcome to bring these to market?

IG: Yes, there are many obstacles of unawareness from the customers. Many people are not familiar with this concept and think of it as a regular mono Bluetooth ear piece, so we are heading to a long journey of explaining our product and turning it into mainstream.

Axum: The Future of Wireless Audio 5

CGM: How do you feel these headphones will do with a crowded market? What sets Axum apart?

IG: We have full confidence in our product. First of all we know 100% that no matter how good your BT earbuds are, if they are not True Wireless they can’t compete with us. As for other True Wireless companies out there, based on their design they’ve never thought about athletes as their potential customers and it’s a shame as this concept is perfect for fitness and exercising. So we already have a huge advantage on them.

Many business and factories are very well aware of their legal obligations when it comes to occupational deafness, and here in the UK we have the Control of Noise at Work Regulations 2006. Many of the headsets that are listed on Headsetonline.co.uk are designed exactly for these types of industries, with their experience they are a leader in radio headsets and hearing protection equipment. But as the article below explains the protection has to personalised to everyone, so as to make sure that the individual is catered for and protected adequately. The original source of this article can be found here.

Hearing loss is preventable. Why, then, is it still so common? NIOSH notes that occupational hearing loss is one of the most common work-related illnesses in the United States. And according to OSHA, approximately 30 million people in the United States are exposed to hazardous noise on the job.

“Noise-induced hearing loss is generally a gradual and painless process, so many workers don’t consider it a hazard … until it’s too late,” said Katie Mielcarek, marketing manager for Cleveland-based Gateway Safety Inc. Mielcarek went on to say that workers don’t wear hearing protection for many reasons, including discomfort, poor fit and problems with compliance monitoring and trouble inserting earplugs.

Here, industry insiders discuss what’s new and offer advice on hearing protection.

What’s new

“Electronic muffs contain the latest technology designed to protect against environments with impulse noises,” said Eric Moreno, market manager for Cranberry Township, PA-based MSA. “The technology amplifies weak sounds while compressing dangerous noises to a predetermined safe level of 82 dB or lower.” Moreno said this allows face-to-face communication and lets workers hear important sounds, such as warning signals.

Gary Klee, product manager for above-the-neck products at Latham, NY-based Protective Industrial Products Inc., pointed to a “level-dependent system” available with electronic earmuffs. This system has microphones in both ear cups to help limit sounds reproduced through the internal speakers to a safe level, which “allows communication with others while remaining protected against impulsive or hazardous noise,” Klee said.

Advice

Ricardo Allamelou, COO for Miami Lakes, FL-based Cotral Lab Inc., said providing every worker with the exact same type of hearing protection doesn’t make sense. “The protection has to be personalized since overprotection is as dangerous as no protection at all,” he said.

According to Moreno, “Overprotecting can actually increase the danger to a person’s life because this can hinder their ability to hear relevant noises such as warning signals, moving vehicles, other workers, etc.” To reduce the chance of overprotecting, Moreno recommends thoroughly understanding the level of noise in every area of the workplace to determine what level of protection each area needs.

Additionally, be sure your hearing protection is independently, third-party tested to verify noise reduction ratings, Mielcarek said. “This helps communicate quality in an industry where many manufacturers simply mark their products with a standard or a rating, without the testing to back it up.”

It is quite a common thing that musicians and artists that are exposed to loud noise, will eventually suffer from hearing damage. We have seen many artists suffer from this career threatening damage, the likes of Phil Collins, Eric Clapton and Ozzy Osbourne and the tinnitus that is effecting Chris Martin from Coldplay, this is a problem that many more will be affected by. This article from the BBC talks about Chris Goldscheider and his pursuit of damages over his hearing damage. Rightly or wrongly it’s an interesting tale.

A renowned viola player is suing the Royal Opera House for ruining his hearing and his career during rehearsals of Wagner’s Die Walkure.

Chris Goldscheider claims his hearing was irreversibly damaged by brass instruments put immediately behind him.

The Musicians’ Union says hearing damage is a major problem for musicians playing in orchestras.

The Royal Opera House denies it is responsible, but around a quarter of its players suffer hearing illnesses.

In court documents seen by the BBC, Goldscheider claims that in 2012 his hearing was “irreversibly damaged” during rehearsals of Richard Wagner’s thunderous Die Walkure “from brass instruments placed immediately behind him” in the famous “pit” at the Royal Opera House.

The sound peaked at around 137 decibels, which is roughly the sound of a jet engine. The court documents say the noise “created an immediate and permanent traumatic threshold shift”.

Image captionChris Goldscheider played the viola with some of the world’s greatest orchestras

Goldscheider says this amounts to “acoustic shock”, one effect of which is that the brain hugely amplifies ordinary sounds.

Music has been in most of Goldscheider’s life: “For the last quarter of a century I’ve been a professional musician. Music was my income. It was my everything,” he says.

The son of a composer, from the age of 10 he spent in excess of six hours a day practising and rehearsing. He played the viola with the Royal Liverpool Philharmonic and BBC Symphony orchestras, before joining the prestigious Royal Opera House orchestra in 2002.

Career highlights have included performing live with the famous Three Tenors to 100,000 people at the Barcelona Camp Nou football stadium, and with Kylie Minogue on MTV. He has also recorded with artists including the band 10cc.

Goldscheider says the effects of the hearing damage have been devastating.

“Ordinary sounds like banging cups and glasses together is a very painful noise,” he says.

“My newborn daughter last year was crying so much I actually got noise-induced vertigo because of my injury and I ended up in bed for three weeks.”

The musician says he has lost the career he loved and his mental health has deteriorated as he struggles to cope with the impact and effects of his hearing problems.

Life has changed dramatically. To carry out ordinary every day tasks such as preparing food, Chris has to wear ear protectors. Especially upsetting is that he had been unable to listen to his 18-year-old son Ben – one of the country’s outstanding young French horn players.

“Ben is a fantastic musician. I haven’t been able to listen to him play or practice since my injury. I’ve missed him playing concerts and winning competitions. I can’t even bear him practising in an upstairs room when I am downstairs in the house,” he says.

At the time of his injury, Goldscheider was provided with hearing protection capable of reducing the noise by up to 28 decibels, but his lawyers claim this was insufficient. They say he was not given enough training in how to use it and protect himself, and that the noise levels should not have been so dangerously high.

The Royal Opera House does not accept the rehearsal noise caused Goldscheider’s injury, and denies that is responsible.

In a statement it told the BBC: “Mr Goldscheider’s compensation claim against the Royal Opera House is a complex medico-legal issue, which has been going on for some time and is still under investigation.

“All sides are keen to reach a resolution. The matter is now the subject of legal proceedings, and in the circumstances it wouldn’t be appropriate to comment any further at this stage.”

And according to Goldscheider’s solicitor Chris Fry, part of the Royal Opera House’s defence breaks new legal ground.

“Essentially what is being said is that the beautiful artistic output justifies damaging the hearing of the musicians performing it,” he says.

“That’s never been tested by the courts. We don’t think the court is likely to uphold that, in particular where it’s clear steps could be taken to maintain the beautiful sound and protect hearing at the same time.”

Hearing damage suffered by rock musicians is well documented. Years ago The Who’s Pete Townsend went public about his hearing loss and famously said a doctor had told him: “You’re not actually going deaf, but I’d advise you to learn to lip read.”

Brian Johnson of AC/DC and Ozzy Osborne have also been affected. But what is far less well known is that it is a significant problem in the more sedate and sophisticated world of classical music.

There are around 100 players in the orchestra at the Royal Opera House. The BBC has learnt more than a quarter report occasional or mild hearing illness, and that in the 2013/14 season, there were seven cases of sickness absence related to noise problems and a total of 117 weeks of sick leave taken. That’s not music to anyone’s ears.

Morris Stemp of the Musicians Union says there are many reasons for the hearing damage suffered by classical musicians.

“Conductors are allowed to ride roughshod over health and safety considerations,” he says. “They put players on the stage where they will be in harm’s way. And instruments are now louder than they ever were before because of the materials they are now made from.”

Add to that the increased number of live concerts prompted in part by the drop in income from CD sales, and there is a mix of elements that can put the hearing of orchestra players at serious risk.

Chris Goldscheider’s case casts light on a little known or discussed problem, and will be watched closely by all those in the classical music world.

 

This is an interesting review of a paid article, depicting which is represent by a drawing, painting, or other art form can be used as a form of communications, the type of depicting is described here in many different forms and that is where we will allow the article to take up the story.

When we think of language, we usually think of words, phrases, and sentences–strings of abstract symbols. In research over the past 50 years, cognitive and social scientists have developed extensive accounts of how people communicate with these symbols. But when people are face to face, they also communicate with actions that depict people, objects, and events. They create these depictions with their hands, arms, head, face, voice, and entire body, sometimes with other props but often without.

In an article recently published Online First in Psychological Review, Herbert Clark argues that spontaneous depictions like these are missing from general accounts of how people communicate, and that is a major failing. Why? Because depicting is common in everyday conversation and depicting things is fundamentally different from describing things. Also, a great many utterances are “composites” of depicting and describing.

Clark’s point is nicely illustrated in a report, from the New Yorker, of Hollywood director WG telling correspondent TF about having to stop filming in New York because of some falcons nesting on the ledge of a building:

“In L.A., they would have–” He leveled a finger at some imaginary nestlings and made a gun-cocking sound.

As Clark notes, WG could easily have described the scene with the phrase “shot those falcons.” What he did instead was depict the scene with his finger, hand, head, eyes, and voice. The result included a depiction (leveling a finger and making a gun-cocking sound) in place of the phrase “shot those falcons.” Traditional accounts are unable to handle composites like this.

What is depicting? In the theory developed in this paper, to depict something is to stage a scene. When WG leveled his finger at the imaginary falcons, he enacted a shooter in L.A. aiming a rifle at some falcons. And he did that so that his listener could imagine the scene vividly. Depicting is much the same as putting on a play in the theater or engaging in make-believe play.

Depicting, according to Clark, is largely complementary to describing. To begin with, many ideas that are impossible to put into words are easy to depict. Tennis coaches don’t describe how to hold a racket or do a backhand return. They demonstrate it, and in living detail. Music teachers often correct their students by playing or singing what the students should have played or sung. And although it takes years for children to tell coherent stories, they have little trouble depicting stories in make-believe play. They readily enact Cookie Monster, Mother, cops and robbers–and play out what they do.

Depicting is also effective for emotion, excitement, and empathy. In telling stories and passing on gossip, people not only describe, but dramatize what the protagonists said and did, often with passion and attitude. And in apologizing, people not only say “Sorry” but add facial gestures that depict their regret.

The idea, then, is that depicting is a method of communication. Without depictions, talk would be flat, lifeless, and sometimes even impossible.

This article is from the well trusted tetra-applications.com website This story is about the Belgian tetra system, called ASTRID, running close to full capacity during one of the biggest disaster events that Belgium has seen. The system had a few stuttering moments, but with the unpredictable surge in traffic after the event, this is to be expected. To learn more read below and see what they are planning to do…..

During last week bombings, ASTRID, the Belgian Public Safety TETRA network encountered a huge increase of traffic which resulted in a temporarily capacity problem.

ASTRID, the TETRA radio communications network in Belgium, used by the security forces, has not functioned as desired, after the attacks of last week Tuesday, several media announced. Also the GSM network was down and therefore in some cases WhatsApp had to be used by the security forces.

Commissioner General Catherine De Bolle has requested an investigation. Several media mentioned that for many hours the system would not have worked. Therefore, the rescue operations of the police at the airport were much more difficult and more chaotic than it should be. Spokesman Peter Dewaele of the federal police admits that some things did not run as planned.

Astrid responds

“After analyzing the situation, Astrid requested all user organizations to sit around the table in order to examine the communication after the attacks of 22 March. Meanwhile, concrete action and specific recommendations were specified,”

According to ASTRID, the exceptional nature of the emergency caused that some masts of the radio network could not be reached for a short period of time, because of the enormous increased traffic. Therefore communication was not possible, Astrid announced.

“From across the country emergency and security services were asked to provide assistance, which led to an extraordinary radio traffic. On specific requests of many of these organizations Astrid registered hundreds of extra radios to the network. Also the failure commercial mobile phone networks has led to a significant increase in radio traffic.”

“Not flat, or capacity”

Astrid points out that the control rooms/emergency centers were particularly busy in Brussels and Flemish Brabant, but they continue to function properly. Also the alarm system for calling the volunteer fire brigade received extra traffic, but the system worked without any problem. Astrid also installed a mobile-transmission tower in order to strengthen the radio network in the Brussels area.

On a nationwide level, the radio network was still operational, but especially in the Brussels region there were severe capacity challenges,” Astrid notes. “Shortly after the attacks the nearby Astrid masts reached their maximum output, which resulted in difficult communication during some crucial hours. Some users had no access to their talk groups.”

“On Friday March 25th we discussed the situation with the End User Advisory Committee. Concrete action points and recommendations for the use of the radio network and training were determined,” concludes Astrid.

One question that is frequently asked by people interested in buying two way radios is that can you mix brands of two way radios . To answer this question properly, it is imperative to understand first how the devices work. It should be known that whether you have a small business or a large warehousing facility, UHF band radios never communicate with the VHF band radios. Therefore, if you are looking to buy a radio, make sure to buy additional units of the device of similar bands. In this way be it a UHF band radio or a VHF band radio, if set to the same frequency can work with all brands. However, some considerations have to be put in its place beforehand.

Functionality

Two way radios imply that it can both send as well as receive radio messages. They are transceivers that are battery powered. The radios operate on a half-duplex channel system. This system implies that the radio will be able to transmit a signal on a single channel that can be received on many devices at the same time. Normally these radios are designed to transmit short-range signals. Almost all of the two way radios function on the same principle. They all include a microphone, an antenna, a speaker, and the Push to talk Button. These radios are designed to function on different frequencies.

Frequency types

The general public use frequencies are the Family radio service frequency or the FRS and the general Mobile radio Service frequency or GMRS. Both these frequencies work on a 460 MHz rage. The UHF frequency or the ultra-high frequency is ideal for the two way radios as they can easily penetrate the interference in the form of building and trees. The two way radio with a long UHF antenna will push through the concrete and will do your work efficiently. On the other hand, VHF antennas on the radios are much longer than the ones in the UHF radios. These are ideal to use in the outdoors as they usually can transmit signals over very large distances.

Types of radios

There are normally two types of radios, that are used in businesses and that are used in consumer situations. The consumer radios normally work on the FRS or the GMRS frequencies. Regardless of the number of channels in the radio, the two way radios can be mixed with other brand radios. Only the radios have to be set to the same privacy code, the channel number, and the same frequency. Alternatively, there are several different types of frequency in the business two way radios category. The radios use the UHF, VHF and the 800/900 MHz type frequency. Just by choosing, the radio with the same frequency may not be compatible with the radios of other brands bought beforehand. While buying the radio, the dealer may have programmed a special customized frequency into the radio beforehand. In order for the business, two way radios to work efficiently with the radios of different brands it is essential to completely figure the type of band that the radio uses, the pre-set frequency on the radio from the dealer.
