Sepura Contributes to Success of World’s First Cross-border TETRA System

We take it for granted that when we move around the country our mobile phones connect to the nearest mast, or we go abroad and our phones automatically connect to the network, with tetra, this is not as easy, but this article is about a test that Sepura completed connecting two TETRA networks in Norway and Sweden, interesting stuff.

Sepura radios have successfully participated in interoperability trials for the world’s first cross-border TETRA communication system, linking RAKEL and Nødnett, Sweden and Norway’s public safety networks.

More than 350 first responders were involved in the trials, which took place in Meråker, close to the Swedish border, in a crisis response exercise involving public safety users from both countries.

The cross-border system utilises TETRA Inter-System Interface (ISI) functionality to connect networks together, effectively allowing users to roam to another network. This allows first responders to use their radios in both countries â€" vital for smooth collaboration in emergency situations.

The initiative to strengthen co-operation between national emergency services started in 2013 with the EU-funded Inter-System Interoperability project, designed to improve the ability to respond to natural disasters and security threats. The RAKEL and Nødnett networks are scheduled to be ready for bi-national operational use in early 2017.



Sepura’s STP9000 hand-portable radios and SRG3900 mobile radios were used by both Swedish and Norwegian emergency services during the exercise, although all Sepura radios â€" including the new flagship SC20 range â€" meet the technical requirements of the ISI system.

“This is one of the most advanced multinational radio communication projects in Europe,” said Tariq Haque, Product Manager for Sepura.

“After two years’ development, bi-national i nteroperability has become a reality, bringing cross-border mission critical communications to Sweden and Norway.

“We are extremely pleased to have played a part in this ground-breaking event.”

How To Take Care Of 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 two 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 two 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 a nd 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 2 way radio, you should make sure that it's turned off and batteries are removed.

Charging Your two 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 two 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 shoul d 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 ac cessory can end up shortening your radio's lifespan and can even destroy it.

Cleaning Your 2 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 two way radio in water to clean it.

Conclusion

2 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 2 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 two way radio and keep it in a great working condition.

What Is The Best Way To Select The Right Radio Earpiece

When choosing a radio earpiece, there are several factors that should be considered. A radio earpiece should not only aid in communication it should also protect the user’s ear against cumulative ear damage that may eventually result in ear loss. Below are the factors that you should consider when buying a radio earpiece;

1) Clarity of communication

The most important reason as to why you have a radio is for clear communication and this is what your radio earpiece should enhance. Although there are several radio earpieces out there, many of them use bone conduction when transmitting the user’s speech meaning that they heavily rely on vibrations of one’s skull as they talk. This does not help much in ensuring that the communications are clear especially when one is on the move.

You should therefore go for a system whose in-ear microphone does not use bone conduction and this will enhance the soun d clarity. Such a system can even transmit speeches when one is whispering and this comes in handy especially when in an environment where secrecy is very crucial.

2) Comfort

It is very important to select a system that you feel comfortable with most importantly when you are to wear it on your head. Note that, you will probably be wearing the gear for long hours and that is why it should be of lightweight and should not in any way interfere with your eye wear or helmet.

Avoid heavy, sweaty and coiled tube earpieces that are very uncomfortable and will cause ear fatigue. Instead, go for a radio earpiece whose microphone is built into the earbud itself. Such earpieces come in various shapes and sizes and can even be customized to fit the specific needs of a user. Note that, military-grade materials are specifically designed to be of lightweight.



3) Durability

Durability is a very important factor that should be considered when choosing a radio earpiece. You obviously don’t want to be wasting your time and money going back to look for another earpiece just because the one you chose did not last. This is why it is very important to select a system that is durable and has been tested for rugged use of a soldier or a SWAT officer. Go for one whose manufacturer is experienced in manufacturing earpieces that can withstand water, dirt, shock and even extreme temperatures.

4) Ease of use

Your radio earpiece should be easy to use because you can’t afford to mess up with the push-to-talk or the on & off buttons especially when on the move. Your gear should immediately fit into your actions with minimum effort. Look at the operational and the ergonomic features of the various radio earpieces and make sure that all its features are both of the r ight sizes and in the right places.

5) Hearing protection

Claims related to hearing loss and its related disabilities is on the rise among police & military veterans and this has led to the need for hearing protection for officers. Note that, hearing loss occurs cumulatively over time and it is irreversible. This is in addition to the fact that it has been associated with cognitive decline and that is why even the minor hearing loss can have a huge impact in the course of time. Select a radio earpiece that not only ensures effective communication, but also the hearing safety of the user.

6) Situational awareness

An earpiece is basically meant to keep you focused and keep your hands free. You should be aware of what is happening in their surrounding and that is why a radio earpiece should allow one to hear sounds that are outside, to stay alert with their surroundings.

In order to have f ull communications (just like one would have without anything in their ears), it is wise to choose a radio earpiece that has an external microphone. There are systems that even enable you to adjust volume of the external microphone and this ensures that you are aware of the happenings in your surroundings.

7) Modularity & Compatibility

There are several systems that are available out there and you should look for one that fits your requirements. As mentioned above, some of them can be customized to fit an individual user’s specific needs so you can never run out of options.

A radio earpiece that has a modular connector is good as you can change it to match even a different radio without having to replace the entire system. Some systems can even go with both earbuds and over-the-ear earpieces so depending on your needs, select the appropriate system.

8) Affordability

Many years ago radio earpieces cost £100 and upwards, these days you can ge t a D-ring earpiece for less than £15 and an acoustic tube for about £25. Bone conductor earpieces that were previously and expensive piece of technology, can be yours for about £40.

AXUM: THE FUTURE OF WIRELESS AUDIO

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.

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.

Virtual Reality Coming to Your In-Flight Entertainment?

2016 was the year of the Virtual reality headset, we are seeing the first versions of a technology that can, and possibly will, change our lives, much like the smart phone has. VR has the potential to improve our Games, TV programmes and Movies and allow us to experience things and places better. This article is about how your in-flight might be improved by a VR headsets.

No one likes flying during the holidays. Between having to leave two hours ahead of time and getting through security, just getting to your flight feels like a trip in itself. And then you get on the plane and have nothing to do for three hours except watch reruns of Friends on the little TV in front of you.

That’s probably about to change, thanks to VR. For a little while, of course, passengers can plug into their own Samsung Gear VR sets and tune out, but airlines might be offering their own complimentary variety so you can forget you’re stuck on an airplane.

A French start-up, SkyLights, is developing the tech. It’s a headset with a six-hour battery life, and it comes with noise-cancelling headphones. The headset looks pretty sleek and simple, because they’re made to be: There’s none of the neater interactions you get with an Oculus or Samsung headset. It really is just a movie beamed right into your face. You’ll be able to watch the newest 2D and 3D movies, and the set comes with 128 GB of storage â€" about 40 movies. Weighing only slightly more than half a pound, it’s easy to visualize the headset propped on the back of the seat in front of you, and after paying the fee, you can flip it on and enjoy hi-def movies right in front of your face.

The headsets are being tested in France right now: XL Airways became the first headset to offer a commercial version of the headset to passengers last week, for $16 per flight. SkyLights has also partnered with AirFrance and Airbus. Content-wise, there are partnerships in the works with 20th Century Fox and Dreamworks.



The general lack of viable in-flight entertainment has been plaguing the airline industry for a while; broadband Internet is an extra cost (roughly $10 per flight, depending on your airline), and the movies and TV they show are typically outdated.

It wasn’t until recently that airlines began attempting to match the broadband speed you’d find on the ground. (As of last year, you’d get speeds of around 3.1Mbps, as opposed to the roughly 30Mbps that smartphones on the ground are capable of). Since so many people use their own devices for entertainment, airlines are in desperate need of upping their Wi-Fi speed. But they also need ways to entertain their customers in an inexpensive manner, without the heavy screens and cables that come with TVs. Virtual-reality headsets â€" light, not-too-costly, and wireless â€" could offer a way for airlines to draw their customer base back in. But there are challenges: VR headsets are a relatively new and untested technology.

“Airlines are difficult players to deal with because they are risk-averse and slow to innovate,” David Dicko, SkyLight’s CEO, told the Times.

One potential problem for in-flight VR in your face is the nausea it causes. VR (even if it’s just a film) can be very disorienting, and it’s not hard to imagine people getting sick from it on a moving plane. Oculus’ health and safety documentation is a laundry list of potential concerns, from warnings of dizziness and nausea to seizures and sweating.

Another potential issue could be that hundreds of folks tuned out to a VR movie with noise-cancelling headphones have, at the least, limited awareness of the outside world. That means slowness to react in plane emergencies â€" another potential lawsuit on an airline’s hands.

For now, we’re skeptical that VR headsets will take off as in-flight entertainment in the U.S. anytime soon. Early adopters might be eager to try them â€" but they also have their own headsets that they can use for free. Customers would have to pay over the price of a movie ticket, the technology is unstudied when it comes to users’ health, and everyone has their own phone or tablet to entertain themselves. We love the idea, but, as Dicko noted, the airlines are a pretty risk-averse industry. They should prioritize Wi-Fi bandwidth first (and make it at least cheaper), which is what the majority of customers undoubtedly want.

Anyway, it’s hard to imagine a more Black Mirrorâ€"esque image than a hundred people, arranged into rows, their heads leaning back, eyes hidden behind a headset, plugged in to a world that isn’t there.

What exactly is a walkie talkie headset

A Walkie Talkie is a handheld receiver or portable radio. Walkie talkies come in a pair and they communicate quietly with one another using radio waves, on a single shared frequency band.

Almost all of us grew up with walkie talkies. As children, and especially before the age of mobile phones and technology, we all had a pair and played with them in our gardens.

Walkie talkies have made a comeback. Or maybe they never really went out of style but now they’re sophisticated.

Each unit is battery powered and has an antenna for sending and receiving radio wave message. There is a transmitter / receiver and a loudspeaker. The loudspeaker doubles up as a microphone. There is a button that you push to talk, pretty much the same way that an intercom works. Some more sophisticated walkie talkies have separate loudspeakers and microphones; it just depends on what you need the walkie talkie for.

Walkie Talkies with noise cancelling headsets

Technology has changed so much and become so much more sophisticated. In the old days, think of the crackles that came with walkie talkies. It was often very difficult to hear what the other person was saying. But a pair of noise cancelling walkie talkie headsets will reduce or remove any unwanted sounds by using active noise control. Note that this is very different from passive headphones which use technique such as soundproofing. Noise cancelling is not soundproofing.

Our worlds are busy and we become bombarded and overwhelmed by everything around us. We need to listen to some things, but we want to cut out others. Noise Cancelling allows us to do this, while still allowing us to listen to the things we want to listen to at the volume we want them.

Pros of a walkie talkie headset?

Remember when we used to listen to music really loud so we could block out all the other external noise? You don't need to do this anymore. walkie talkie headsets will block out most excess or excessive sound, or the ones you want blocked out anyway. You can now listen to your music at the volume you want, which does not need to be crazy, and the other external sounds (baby crying, man snoring next to you) will be blocked out anyway. Finally, you can listen to and enjoy music in the way you want to enjoy it, at a natural volume. You can hear the fabulous music, have a rich listening experience, and still not be disturbed by chatter around you.

Noise cancelling headphones are fabulous for when you travel or commute. You may be the kind of person who gets on a plane and train and chats to everyone around you. But you may be more solitary and want to sit down and zone out. You can do this easily with a walkie talkie headset. The beauty is that on a plane you won’t hear the noise of the aircraft or its passengers, but you will still hear the safety announcements.

It’s really easy to work in a noisy environment with noise cancelling headphones. You can focus easily without being disturbed and can make use of any space, productively. You can even go and study your history while at a party or in a restaurant. It is also a good idea to use them at home, while studying for exams or so; they cut out the excess noise and you can focus totally on your work.

Students used to turn up the volume of their earphones in order to cut out the outside world’. But with a walkie talkie headset they are finding it is easier to study when music is at a lower volume and when the outside distractions have been eliminated.

Cons to noise cancelling headphones?

There are always cons to everything. Some parents may say they would prefer no headphones at all. They like their children to be available and to engage more and talk more, but we know this is the way of the world. Everyone uses headphones; parents included/ Use them in moderation of course, but still be sociable and take time out in the day, be headphone free, and engage.

Noise cancelling headphones are not very cheap and are in fact possibly even ten times more expensive than ordinary headphones. However, like anything that costs money, they will last for a long time and are super reliable. They may cost more money but will ultimately give a much better noise-free experience.

Lots of research has gone into the design of these special noise cancelling headphones. Each set consists of inner components that cancel out the disturbing external sounds. Ordinary headphones do not have these components, i.e., you cannot cut out the outside sounds. It is quite obvious then, why noise cancelling headphones are more expensive.

These internal components also use up a lot of power. The power can come from internal replaceable batteries or they can be rechargeable. The walkie talkie headset that carry their own power supply means they are heavier than ordinary headphones. Not all sets carry their own power supply. The ones that are rechargeable are lighter, but they can drain the devices they need to plug into for power.

The quality of sound when using a noise cancelling walkie talkie headset can be compromised. It is unusual though and it is only the most sensitive of ears that would pick this up. There have been very few complaints of a tinny almost mechanical sound, but these complaints are few and far between.

Not all sounds are blocked out by a walkie talkie headset, although we did mention this under pros as well. It is never possible to cancel out all external sounds, but we still need to be able to hear police sirens, pilot announcements or the high pitched screaming of your next door neighbor. All every day external sounds though are muffled and definitely much quieter, and the sounds that you don't need to hear, are gone.
