Occupational health effects linked to terrestrial trunked radios (TETRA)

Tetra has been the main stay for the Emergency services for over 10 years and it has been a used by other industries for longer than that. There has been plenty of time for health concerns to be brought up and as the technology is similar to mobile phone, which has been around for 20+ years and radio communications (walkie talkies) for much longer than that, and no really hard evidence has ever been brought that either of these two cause health issues, this article probes the possibilities of TETRA causing health concerns, see what they uncover below.

The use of terrestrial trunked radios (TETRAs) has raised concerns about health and sickness absence. Jackie Cinnamond looks at the evidence for a precautionary approach.

The British police and the other emergency services use a communication system involving technology called TETRA (terrestrial trunked radio), which is halfway between a mobile phone system and a walkie-talkie.

At one NHS trust during the autumn of 2013, it was noted that there seemed to be a correlation between increasing levels of sickness absence in ambulance staff and the recent introduction of TETRAs.

This assumed association was based upon clinical presentations of cases being seen in occupational health practice involving ambulance service employees, who maintain that their portable radio handsets are causing them to experience adverse health effects.

TETRA is the leading public safety radio communications system worldwide, and serves to enhance the function of almost 500,000 police, ambulance and firefighting employees (Airwave solutions, 2012; Motorola, 2007).

The Government commissioned TETRA in 2005 at a cost of £3 billion. It did so in response to concerns raised by the Police Federation regarding the use of a two-way radio communication system and its link with breast cancer in female operatives (Police Federation News, 2005).

The use of TETRAs was contentious due to similar health fears raised by the Health Protection Agency and its working group of 2001. Consequently, the Airwave Health Monitoring Study started in 2009 and the findings are due to be released in 2018 (Imperial College London, 2009). This long-term, observational study is investigating health outcomes of TETRA users within the police force.

Initial concerns were raised by Lancashire police after it was introduced, when almost 200 police officers began to experience symptoms of nausea, malaise, head pain, insomnia, skin complaints and two cases of oesophageal cancer (Farrell, 2002; Police Federation News, 2005).

Comparably, these symptoms correlate with reports of symptoms experienced by the ambulance employees within this trust, soon after the TETRA system was purchased, and which could be associated with electromagnetic radiation emitted by this technology.

Technical issues related to TETRAs

Radiation is a source of energy produced during atom separation. The process of ionisation results in the addition, or removal, of one or more electrons from an atom or molecule.

The force of the electromagnetic energy waves released during separation are categorised as either non-ionising, where the energy released is insufficient to ionise matter, or ionising radiation, where adequate energy is present to ionise matter (Tillman, 2007).

Ionising radiation is associated with the X-ray process; and non-ionising radiation is associated with the transmission and receipt of mobile telecommunication signals (IEGMP, 2000).

Electromagnetic fields are quantified by their wavelength, and the frequency at which the wave pulsates (Sanchez, 2006).

The wavelength frequencies are expressed in Hertz (Hz) and oscillate within a spectrum where one Hz is one oscillation per second, and one kiloHertz (kHz) is 1,000 Hz. Radios using 16-17Hz should be avoided as these frequencies are known to adversely affect health. TETRAs operate at a frequency of 17.6Hz

Potential implications for health

Mobile telecommunication devices are a cause of contention. The health effects associated with their use remain unproven (Kundi, 2009). Human stem cells are more susceptible to electromagnetic fields compared with differentiated human primary cells. The constraining influences of electromagnetic fields upon DNA regeneration in human stem cells could manifest itself in the development of abnormalities within the DNA replication process. Consequently, the initiation of cancer may result (Valberg et al, 2007).

With an estimated 500,000 emergency service employees currently using TETRA systems, if a causal relationship between the use of portable radio handsets and cancer development was subsequently established, then this could present a significant OH and public health challenge (Health Professionals Council, 2011; Dhani, 2012).

Current research

The incessant proliferation of wireless telecommunications technology use has intensified public fears and generated international debate regarding the chances of cancer developing as a direct consequence of exposure to electromagnetic fields emitted from devices such as mobile phones (Kundi, 2009).

Research findings accumulated over the past decade suggest a causal relationship between electromagnetic exposure through the use of wireless telecommunication systems and cancer development (Levis et al, 2011). Conflictingly, current research results conclude that there is insufficient evidence, or none at all, to suggest that acceptable electromagnetic frequencies emitted through mobile phone use can cause adverse health conditions or cancer (Kundi, 2009).

However, the majority of current research studies are sponsored by the telecommunication industry and, therefore, findings tend to significantly underestimate cancer risk. The overall accumulation of research findings, regardless of study design imperfections and financial bias, leans towards the opinion that there is an increased likelihood of a causal relationship between mobile phone use and cancer (Kundi, 2009; Levis et al, 2011).

Legislation related to TETRAs

Although most technology poses some level of risk to human health, such threats must be measured precisely and dependably (Levis et al, 2011). Presently, two international organisations – the International Commission on Non-Ionising Radiation Protection (ICNIRP) and the National Radiological Protection Board (NRPB) – have produced guidelines for limiting exposure to electromagnetic fields within the UK and the European Union (EU).

The ICNIRP (1998) recommendations have been integrated into the European Council Recommendations (1999) and have subsequently been incorporated into statute in Germany (WHO, 2011).

Limits for human exposure to electromagnetic fields have been set accordingly by the ICNIRP and the NRPB (1993) at between 10 and 300 GHz. However, the ICNIRP guidelines have established an upper limit for occupational exposure that is five times higher in employees than it is in the general public (IEGMP, 2000). The exposure limit values are referred to as “basic restrictions” and are based upon specific absorption rate (SAR), which equates to the rate at which the body absorbs energy in relation to each unit of body tissue (WHO, 2011).

Precautionary principles for TETRA use

In the absence of accurate guidance and methods for measuring exposure levels, the robust research evidence that establishes a causal link between electromagnetic exposure and cancer should be acknowledged and precautionary principles implemented (Hardell et al, 2005).

Precautionary principles with regard to electromagnetic radiation are defined by Valberg et al (2007) as implementing a safety-conscious approach prior to a significant causal link between electromagnetic fields and cancer development being established. The idea behind introducing precautionary principles is to try to reduce the degree of public concern regarding the potential health implications of exposure to electromagnetic fields (Wiedeman and Schutz, 2005).

However, the implementation of precautionary principles would be subjected to a cost-benefit analysis and, therefore, would be measured against what the populace deems financially equivalent to the cost of similar risks to society (Australian Radiation Protection and Nuclear Safety Agency, 2001).

Furthermore, their implementation may adversely increase the publics perception of risk and induce a psychosomatic-related development of adverse health problems and proceed to over burden already stretched resources unnecessarily.

However, the Bioinitiative Working Group (2012) contends that the public health approach to addressing exposure to electromagnetic fields should be viewed in the same regard as passive smoking and established on the current scientific evidence accessible.

Implications for OH

Despite the health risks associated with electromagnetic field exposure, the National Policing Improvement Agency continues to emphasise to its employees that the only adverse health effects of electromagnetic fields are established through tissue heating at significant levels.

It also discredited the accounts of the symptoms experienced by employees as psychosomatic conditions (Farrell, 2002; Police Federation News, 2005).

However, Kundi (2009) affirms that the carcinogenic effects of electromagnetic fields over a prolonged latency period are equivalent to the same intensities for smoking-related cancers. Furthermore, the latency period for cancer development is estimated to be 10-30 years. This raises concerns regarding the increased age of retirement, because occupational health departments could potentially have to adapt to accommodate older workers who have been subjected to long latency periods of electromagnetic exposure and its associated health conditions.

The Global Occupational Health Network (2006) advocates that staff undertaking occupational roles with a potential carcinogenic risk should be properly educated and instructed about the appropriate precautionary measures for working with carcinogens, in accordance with health and safety protocols.

The duty of care under s.2 of the Health and Safety at Work etc Act (1974) requires employers to implement what is reasonably practicable to safeguard the health and safety of their employees through the establishment of safe systems of work, and to ensure that staff are adequately informed regarding any potential hazards.

The Independent Expert Group on Mobile Phones maintains that a precautionary approach to the use of mobile phones be adopted until more detailed and scientifically robust information on any potential health effects becomes apparent.

Conclusion

Telecommunication technology will continue to evolve and may be associated with future health risks. In the absence of any substantial research evidence to conclusively prove that exposure to electromagnetic fields does not pose a risk to health, precautionary measures should be implemented.

The emphasis of these measures should include policy changes that keeps pace with technological developments. This goes hand in hand with evidence-based practice and processes that educate employers and employees, aimed at minimising the potential health risks associated from prolonged electromagnetic field exposure. The findings of the airwave health monitoring study are eagerly awaited.

NFL investigating Giants for using two-way radio during game against Cowboys

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.

WiFi Enabled LTE Small Cell Gateway Market to Register a Strong Growth By 2021 – PMR

On paper, connecting walkie talkie radios to a Wifi networkis is the most obvious method of controlling and communicating within a business. But the reality is that there aren’t many radios on the market that have the capability to do this and many wifi networks aren’t robust enough to manage lots of radios, this article predicts that this technology will be a growth market, we will wait and see.

WiFi enabled LTE small cell gateway is a type of a base station. Base station uses cellular wireless network for communicating with mobile phones or terminals. Base station connects mobile phones to a wireless carrier network and offers local coverage for a wireless network. The area of coverage varies from several miles to few city blocks. Each base station is typically owned by one carrier or wireless company and gives coverage only for that company’s network. It may also offer roaming coverage for other networks in case carriers have agreement for roaming and technology is compatible. Base station comprises of an electronic cabinet which connected by means of cables to a group of antennas. The antennas may be mounted on an existing structure or on dedicated tower structure including top of a building, church steeple or smoke-stack and water tower.

In radio communications, base station refers to wireless communications station implemented at a fixed location and used to communicate as wireless telephone system including cellular GSM or CDMA cell site, part push-to-talk two-way radio system, terrestrial trunked radio and two-way radio. A single location often operates several base stations owned by a different carrier. Smaller types of base stations or small cells include picocells, femtocells and microcells. WiFi enabled LTE small cell gateway is promising network element. A wide variety of base station deployments are in a small cell configuration. It has WiFi interface at end-use device and LTE interface at the carrier network.

Small cell is low-powered radio access nodes (operator-controlled) that operate in carrier-grade Wi-Fi (unlicensed) and licensed spectrum. Small cells normally have a range from 10 to numerous hundred meters. Small cell base stations are expected to play vital role in expanding the capacity of wireless networks due to increasing mobile data traffic. Mobile operators are increasingly looking forward to this technology in order to meet the rising demands for data, video and application access generated due to smart phones and other devices. Small cells aid mobile service that detect presence, interact wand connect with existing networks. Small cells offer increased quality of service and flexibility at an affordable cost. Small cell infrastructure implantation is an environmentally friendly approach as it reduces the number of cell towers and offers a cleaner signal using less power.

Rising numbers of wireless carriers or companies are taking dedicated interest in this industry owing to the proliferation of embedded WiFi features in fixed and mobile devices. Growing demand for more advanced handheld devices such as smart-phones and tablets is expected to create demand for technologies with high internet speed. This in turn, is expected to drive the growth of WiFi enabled LTE small cell gateways.

How To Look After Your Two Way Radio

Buying two way radio equipment is a very beneficial investment, but in order for you to get the most out of your money you should ensure that the equipment is well cared for. If you use and maintain your two way radios with proper care, they will function at their optimum capacity and you can expect them to last for many years. While no two way radio can last forever, there are some simple practices which can help extend the life expectancy of your 2 way radios and ensure they function at their very best. In this article, we are going to take a look at some of the top care tips for your 2 way radios;

Storage

You should always store your radio(s) correctly so as to keep it in a tip top condition. The ideal environment for storing your radio involves a cool and dry (ideally at room temperature, which should be about 72 degrees Fahrenheit) with limited exposure to the extreme weather conditions like excessive cold or heat, and such other elements of water and sunlight. Excessive temperatures can easily damage the batteries; the moisture may end up corroding the batteries. Also, when storing your two way radio, you should make sure that it’s turned off and batteries are removed.

Charging Your 2 way Radio

First of all, you should know that 2 way radios are usually slightly different, so you need to familiarize yourself with the specific charging instructions of your radio. That being so, it is important to note that nearly all of the manufacturers will advise that you to turn off your radio while it’s charging. If you do not, your radio will be drawing current and also charging at the same time, and this can end up shortening the lifespan of the battery.

Overcharging your radio batteries can also cause numerous problems and will have a negative impact on its’ overall battery life, so you should make sure that when it’s charged fully you unplug its’ charger; do not leave it charging all through the night if its’ likely to remain fully charged for a long period of time while its’ still being charged. When you buy new batteries its’ the only time you can leave the radio charging overnight before you start using them for the 1st time; it’ll help you get the maximum battery capacity.

Day to Day Use

Every 2 way radios user should be very mindful of their daily use. Although there are some 2 way radios which are designed to be quite robust, like the explosion proof and waterproof radios, they should still be treated with great care, always. Even if you have a waterproof or explosion proof radio, do not subject it to extreme temperatures.

You should also avoid grabbing your two way radio by its’ antenna, as this will eventually have a negative impact on your radio’s reception and transmission quality. In addition, you should also avoid drops so as to maximize the long term functionality of your radio; consider using 2 way radio belt clips so as to reduce the chances of your radio getting dropped and subsequently getting damaged. Protecting the exterior of your radio helps protect its’ interior, thus minimizing the repairs and the replacing of the equipment.

Another important tip to note when it comes to the day to day use of 2 way radios, is you should never expose your radio to any solvents (unless it has been designed to be used in the harsh conditions); this includes any cleaning fluids and alcohol. Also, try and stick with the accessories which are designed specifically for your particular type of radio; this is especially important when it comes to your radio battery, charger and adapter. Using an incompatible accessory can end up shortening your radio’s lifespan and can even destroy it.

Cleaning Your two way Radio

You should regularly clean your radio to keep it in good working condition. The most effective and efficient way of cleaning your two way radio also happens to be one of the easiest ways as well; strong chemicals or intensive cleaning isn’t necessary. The only supplies you’ll need include some water and a microfiber cloth. The microfiber cloth will effectively wipe away the smudges and dirt without causing any damage to your radio. As for the more stubborn marks and stains, you can use a damp cloth and then wipe until the radio is clean. Remember, never immerse your 2 way radio in water to clean it.

Conclusion

two way radios are among the most versatile and toughest communication solutions, often lasting for many years before needing any repairs or replacement. However, in order to extend the lifespan of your two way radio even further, it is best to employ the above tips for 2 way radio care to fully secure your investment. Protecting your 2 way radio will not only increase its’ longevity, but it also ensures that you will always have reliable communications. Well, as you can see above, taking care of two way radio is relatively easy, and the amount of maintenance required is minimal. A simple cleaning now and then, proper handling, maintenance and storage is all you need in order to extend the lifespan of your 2 way radio and keep it in a great working condition.

Maplewood-based 3M launches ‘smart’-hearing protection for hunters, civilian shooters

We all understand the difference between active headset and passive headsets? Active is able to block external sound when it reaches a certain decibel level. This is great in most situations, but for hunters and people that work around guns this sometimes isn’t as protective as it could be, But now 3M have launched a new ‘smart hearing’ Headset

Determined to expand its consumer safety offerings, 3M Co. has introduced a “smart” hearing-protection headset for hunters and shooters that automatically measures and cancels out specific gun noises while simultaneously amplifying voices and phone conversations.

3M’s device, the Peltor Sport Electronic Hearing Protector, was introduced last week with positive reaction at the National Shooting Sports Foundation’s SHOT Show in Las Vegas.

The technology is designed to offer superior hearing protection to hunters, firing-range hobbyists and other civilian sports shooters.

While 3M is well known for making ear plugs and other hearing protectors for factories, farms and the military, the new Peltor product is expected to greatly expand its reach into the civilian shooting market.

It is also 3M’s first foray into the adjustable or “smart” hearing-technology arena, officials said.

For the first time, 3M’s new devices can measure the energy coming from each specific gunshot in the area and automatically adjust to suppress each noise for the right amount of time.

Such automatic adjustments protect the hearing, no matter if shooters who are nearby are firing small .22-caliber firearms or automatic rifles, said Lindsay Adams, 3M’s marketing manager for the Peltor Sport line.

The new Peltor Sport headsets also filter out sound from fans, wind and other background noises while amplifying voices.

Shooters don’t need to remove headsets to talk on a cellphone or to hear the people around them. Instead, the technology attempts to make ear protection seamless and constant even if the shooter’s environment changes from inside to outside.

“Hunters need to be able to hear their surroundings,” Adams said.

It took 3M more than a year and eight electronic and mechanical engineers and marketers to produce the new products.

If successful, the Peltor Sport headsets will double and triple 3M’s current protection sales from the hunting and shooting consumer market.

3M has a solid footing in hearing protection in the construction market via channels such as Home Depot and Lowes.

Now, 3M hopes for similar success as it launches the new smart Peltor Sport line in Gander Mountain and Bass Pro Shops and on Walmart.com and Amazon.com.

3M launched two versions of its new Peltor headset at the SHOT show. Attendees were able to borrow 3M’s headsets and test them during the preshow firing range event and gave rave reviews.

Unlike previous models, the Peltor Tactical 500 model is Bluetooth capable and offers a noise-reduction rating of 26. The Tactical 300 model is compatible with other mobile devices and offers a noise-reduction rating of 24.

Noise reduction ratings generally range from 0 to 34. The higher the number, the better the noise cancellation.

The new products are expected to sell for roughly $149.99 and $199.99.

“We really feel like these, along with the products we developed in the last two years, round out our portfolio and put us in a competitive position to gain market share,” Adams said.

Both new electronic hearing protectors also feature foldable vented headbands that can release heat and increase comfort.

They sport low-profile cups with rubber bumpers and durable recessed microphones to reduce wind noise.

3M officials declined to reveal the cost to bring the new product to market.

The company does, however, expect the investment to pay off.

Industry analysts agreed, noting that the Maplewood based maker of Scotch tape, respirators, ear plugs, goggles and harnesses has its sight set on a growing market.

Global Industry Analysts Inc. predicts that U.S. hearing-protection sales will grow on average 6 percent a year and reach $714 million by 2020.

Some of that growth will be fueled by regulations and changing hearing-protection needs in workplaces such as factories, oil fields and farms.

If correct, that bodes well for 3M and Honeywell Inc., the two largest players in the nation, followed by SensGard, Westone, Moldex Metrics and David Clark Co. Inc.

How Many Walkie-Talkies Can Operate on the Same Channel?

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.

Spy Earpiece: A Micro Earpiece That Will Help You Through Presentations, Interviews, Speeches + More

When you think of a spy earpiece, the first thing that comes to mind is inspector gadget or Mission impossible, well it does for us anyway. But there are real world applications for these earpieces are wide. As this article explains, when you need a little help with prompts on a big presentation or you need to receive instructions during a lecture, then a micro earpiece could be the answer.

This device originally developed for covert operations is now made available for the public to use. Each earpiece kit can provide a way for you to transmit and receive audio information without anybody in the room knowing. Whether you want to receive pre-recorded messages or information from another party to assist you during your presentation / interview or speech, the earpiece can be set up with your phone, audio recorder, radio, or MP3 player to send the message to your earpiece , placed in your ear channel so that it is undetectable .. All kits also include a built in microphone so that you can engage in 2 way conversation should you wish

So how does it work?

The key is the inductive transmitter that will transmit audio from a phone / mp3 player to the earpiece. The transmitter itself is available in many forms. For example the transmitter may be included within a neckloop to be worn around the users neck, this may connect to your phone or mp3 player via its earphone socket. Or you may have a Bluetooth are often included in everyday objects such as a pair of glasses, a Pen or even a bluetooth watch. The transmitter acts as the aerial for reception and signal transmitter from phone to earpiece. At the same time, output sound picked up by the tiny microphone attached to the neckloop / pen / glasses is sent through your phone just as if the user is talking directly into it.

How to Use The Spy Earpiece?

Depending on what kind of information you wish to receive the earpiece can be set up to suit. For example during a presentation or speech you may wish to pre-record your speech or presentation on an mp3 player, then play it back to yourself during the presentation / speech. Or simply record a simple prompt for each point you would like to make. You could then connect up your mp3 player to an inductive neckloop included in most earpiece kits, and wear a spy earpiece. So long as the battery is inserted into the earpiece you will hear the audio from your mp3 player in the earpiece.

Alternatively you may prefer to have a team prepped in another room to assist you during your speech. This can be achieved by simply starting a mobile phone conversation with your team just before the speech starts. You would then need to either connect an inductive neckloop to the headphone output of your phone, or pair your phone with a bluetooth induction neckloop / pen / glasses. Insert the earpiece into your ear making sure the battery is inserted correctly. Your team should be able to hear your speech in real time over the phone, and can give you tips in your earpiece along the way. The same may apply in an interview situation, you may wish to have a third party issue you advice during your interview.

Each Inductive transmitter whether it be a neckloop or a bluetooth device like a pen, glasses or bluetooth neckloop, will also include a built in microphone so you can also talk back to your colleagues should you wish during your speech / presentation or interview.

Lets not forget the original intention of the Spy Earpiece which is for security and covert surveillance. The Spy Earpiece excels in these situations where the requirement is for a security operative to communicate covertly.

The key to success is in the careful planning and preparation so that everything runs smooth.

The way I see it, when the challenge is great and the results mean everything, why not try the Spy Earpiece and take the risk out of the equation?

MIT’s new method of radio transmission could one day make wireless VR a reality

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.

Imtradex Aurelis Handheld Microphones Future Proof to fit all Purposes

We call these Remote Speaker Mics (RSM) and they have come in all different shapes and sizes over the years. Normally a staple of the emergency services, but we have seen a upsurge in general radio users using RSM’s. So it comes as no shock to us that a pro-active company like Imtradex has designed one to suit the needs of the masses.

What was originally developed as a handheld microphone for digital radios, has blossomed over the past few years to an essential equipment accessory for digital radio standards of emergency service: The Aurelis hand microphone from Imtradex.

Meanwhile with the Aurelis, the specialist for critical communications, have a whole series of hand microphones on the market, all adapted to the specific challenges of the communication in critical applications of security agencies, fire departments, dispatch and emergency services. The Aurelis series addresses the different needs of the user: based of the basic model Aurelis Base, Imtradex manufacture customized versions that are specially tailored to the range of functions that meet the customer’s requirements.

All the Aurelis hand microphones have a send button, a microphone and high quality speakers. “All devices contain a cable attachment and also the possibility to connect external audio accessories” adds Ralf Kudernak, CEO of Imtradex. Depending on the radio, different data applications can be integrated, so can ex. on the model Aurelis AudioDis, information be displayed on the LCD display.

“The youngest member of the family is the Aurelis USB handheld microphone, which is designed for connection to computer-based communication system, especially for control centers” informed Ralf Kudernak. “The USB interface gives the easy integration and can be connected independently to each operation system and used with existing hardware.
