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 ne tworks 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 y ears’ development, bi-national interoperability 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.”

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 fo r 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 d eployments 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 infrastruct ure 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 no t 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 ent ertain 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.

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?

Offering workers hearing protection options

Much Like Protecting your sight or looking after your health, your hearing should also be protected, this article tackles hearing protection within the workplace and what type of earplugs are best, Enjoy.

OSHA regulations dictate we offer a “variety” of hearing protectors to noise-exposed workers. What is best practice for providing a variety while keeping inventory to a minimum?

Per CFR 1910.95(i)(3), “Employees shall be given the opportunity to select their hearing protectors from a variety of suitable hearing protectors provided by the employer.” But does “variety of suitable hearing protectors” mean two or 10, earplugs or earmuffs, different colors or different sizes?

The wrong approach is to choose a variety based on factors that have no effect on protecting hearing, including the published noise reduction rating. Some safety managers offer several different large foam earplugs that are yellow, green and orange â€" mistakenly assuming they meet the “variety” requirement and not realizing that a significant portion of their workforce will never achieve an adequate fit with a large foam earplug. In those cases, their supposed “variety” actually limits the number of workers adequately protected.



This bad assumption is often codified into company safety policies that require a minimum NRR: “Approved hearing protectors must have an NRR of at least 32 decibels,” or similar criteria. By definition, that typically means a large foam earplug. Despite the higher NRR based on 10 laboratory test subjects, workers with smaller ear canals will never achieve an adequate fit with those large foam earplugs to stop noise-induced hearing loss.

What are the factors that affect good fit of an earplug?



  • Size: Like a cork in a bottle, an earplug that is too large or too small will never achieve an acoustic seal to protect hearing. Offering a variety of sizes significantly improves the percentage of employees obtaining a good fit.


  • Shape: Ear canal openings may appear round, oval or slit. A foam earplug often fills an oval or slit opening better than pre-molded earplugs.


  • Ease of insertion: Some workers have difficulty rolling or inserting foam earplugs due to lack of mobility. For these workers, an earplug with a stem may be easier to insert.




Based on thousands of fit tests administered to workers in the field, the following four earplug styles provide a selection that would adequately protect nearly every worker:



  • Large foam earplug


  • Smaller foam earplug


  • Large reusable earplug


  • Smaller reusable earplug




The good news is that offering a variety does not necessarily increase cost. Buying 1,000 earplugs of one style or 250 earplugs of four different styles is fairly equivalent in cost. But the bigger variety significantly increases the probability that more workers will be adequately protected.

Many worksites adjust their inventory based on results of their fit-testing of hearing protectors. By reviewing which earplugs repeatedly provide the best fit, these companies identify the gaps or duplications in their offering and can adjust accordingly. Sometimes, this means adding a smaller-size earplug, but many times companies find they can remove some less-effective earplugs from their inventory. It’s not necessary to carry a dozen different earplug styles.

Finally, any offering of hearing protection needs a hands-on training component. How can a workers determine whether their ear canal is large or small, round or oval? It’s impossible to view your own ear canal opening in a mirror. A quick glance by a safety trainer can be of tremendous benefit in helping workers select the right earplug the first time.

How 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 sound 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 right 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 full 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 get 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.
