Airbus to display resilient PMR communications infrastructures and solutions at ShieldAfrica 2017

ShieldAfrica was started in 2013 and is a security conference for institutional and private operators to meet with companies to promote products and ideas, this years (2017) main theme is Safe Cities, component of Smart Cities, driving investment and economic development to the concept of connected and safer cities. Airbus are turning up to this years exhibition and they are showing off their PMR infrastructures, the source of the article is here, but you can read the whole lot below

To support the economic development of African societies and governments in a challenging security context, Airbus Defence and Space will show its latest radiocommunications technologies at the exhibition “ShieldAfrica” in Abidjan, Ivory Coast, in la te January 2017.

Police, firefighters, and rescue services in Africa are increasingly in demand of more advanced and secured mobile communication tools. “ShieldAfrica” serves as a platform to discuss security applications which require sophisticated Professional Mobile Radio (PMR) technology on the continent.

Secure communications infrastructures

“Government organisations, such as police and emergency first responder services, need secure communications infrastructures for the whole of their national territory and also for critical sites, such as airports, ports and stadiums,” says Philippe Devos, Head of Strategic Campaigns and Government Affairs of Secure Land Communications at Airbus. “We can offer the needed communication means in Africa based on our profound experience as a world-leading PMR provider.”

African security and defence sectors

“Shieldafrica” is a key event f or the African security and defence sectors and hosts the major players in this field, for instance African governments, the global security and defence industry and representatives of diplomacy. Besides showing newest achievements in mission critical communications, Airbus will also showcase the following solutions:



  • Tetra digital radio systemsassociated with modern command and control applications and handheld radios can support effectively shared network deployment models. With these systems at hand, dispatching positions of vehicles or persons can be managed easily by geolocalising Tetra subscribers or groups.


  • The Tactilon Agnetapp brings Tetra push-to-talk to an LTE smartphone. It allows users of commercial LTE networks to communicate securely within mission-critical Tetra networks.


  • The Tactilon Dabat, a smartphone and full Tetra radio in one device, enables users, suc h as police or firefighters, to operate securely with multimedia functions.




Providing interoperability



For more than 25 years, Airbus has equipped various governments around the world with resilient PMR communications infrastructures and solutions. The company has a proven track record of nationwide deployments providing interoperability to all security users organisations.

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.

Motorola Solutions’ digital two-way radio technology enhances mission-critical communications at Munich airport

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

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

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



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

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

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

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

Introducing Ursa Straps – the Perfect Addition to the Radio Microphone Box

Now it’s not the usual field that we cover, but it hit our radar. How many times have you seen an enthusiastic presenter or an excited contestant on TV drop their radio mic and crawl around on the floor, trying to pick it up! Well when a costume designer and a sound man get together then things get designed, and why this hasn’t be invented before is beyond us, but it looks like an idea that could take off. Read the full article here.

Sound recordist Simon Bysshe and costumier Laura Smith have combined their knowledge and expertise to create URSA Straps, a unique range of low profile body worn straps designed to conceal radio microphone transmitters.

Introducing Ursa Straps â€

Officially launched this month and now available in the UK and Europe, URSA Straps are made from a specially developed bonded fabric that is ultra-slim and provides excellent stretch, comfort and breathability. Each strap incorporates a pouch to keep the transmitter locked in place and a cable pocket for managing excess microphone cable. URSA Straps are available in black, beige and brown skin tone colours and can be worn around the ankle, thigh or waist.

Bysshe and Smith developed URSA Straps after listening to numerous artists express discomfort while wearing radio mic straps. Traditional thick neoprene or elastic straps can irritate the skin, become soaked in sweat and are often impossible to disguise under figure hugging costumes.

“It was obvious that a better way of discreetly securing transmitters was required,” Simon Bysshe explains. “As a boom operator I had worked with many artists who disliked wearing transmitter packs because their associated straps could restrict movement and become uncomfortable. In some cases they had simply refused to wear them.”

Laura Smith’s knowledge of costume making proved invaluable as she was able to construct prototypes and identify the exact fabrics required to suit the needs of costume, artists and sound departments.

“After many months of research we decided to create our own unique hybrid fabric by fusing two stretch fabrics together,” Bysshe explains. “This resulting fabric is just 1mm thick and much lighter and softer than any other fabric of its kind. Crucially we incorporated a hook Velcro compatible outer surface that allows the straps to be securely attached to themselves at any point.”

Introducing Ursa Straps â€

Bysshe tested the new straps while working on the second series of Sky Atlantic’s The Tunnel. Lead actress Clémence Poésy was an immediate convert and provided valuable feedback to help develop the product. Bysshe has subsequently used URSA Straps on the third series of Peaky Blinders. The USRA Thigh straps were particularly popular with the cast members who found them secure, light and comfortable. The fact they can be worn around the thigh as opposed to the waist made them invaluable for use with the period costumes.

“With URSA Straps we have created such a comfortable low-profile solution that artists often forget that they are wearing them. Now we have to make sure that actors remember to take them off before they leave!” Bysshe adds. “The straps can be washed and re-used every day for many months. Our Thigh straps are particularly popular as they are designed to not slip down the leg. We achieved this by bonding on a strips of Polyurethane gripper to the inside of the straps.”

Outside film and television, URSA Straps are also proving popular with dancers who need to receive audio cues during a live performance. Using waist or thigh straps the sound team can easily conceal a receiver pack on their bodies without restricting movement or compromising the look of their costumes. URSA Straps have also developed a Double-Pack strap allowing artists to wear two packs on one strap.

Oscar-winning production sound mixer Simon Hayes was an early adopter of URSA Straps and describes them as a total game changer for his team.

“URSA Straps allow us to rig radio mics on costumes previously thought to be unmicable. Tight dresses, sportswear, stunt harnesses â€" they can all be easily miked using low profile URSA Straps. These straps are so popular with the actresses I work with that many have asked to keep theirs at the end of the production.”

URSA Straps are suitable for a variety of wireless transmitters including Lectrosonics, Zaxcom, Wisycom MTP40 and Sennheiser 5212. Two different pouch sizes are available to ensure optimum fit. Three different waist sizes are available: small, medium and large.

“Initially Laura and I were making the straps by hand in our garage,” Bysshe says. “When we realised their potential we scaled up production by taking on two experienced manufacturing firms in Leicester. Our launch has been a huge success with orders coming in from all around the world! We are now on our third large production run and expanding our market into Theatre, Concerts and Outside Broadcasts.”

Motorola Solutions announces new mobile radio, enhancements to its P25 platform

Motorola Solutions are busy re-modelling their business at the moment and are under pressure from many other radio manufacturers, that are stealing away their market share. They are moving towards creating equipment that can use the LTE, essentially competing with the mobile phone market. This will be seen by many as a move away from the essence of two way radios, but it is an inevitable progression. This new radio will use current motorola earpieces, chargers and batteries. We brought you this article from the urgentcomms websites

Motorola Solutions today will unveil a new P25 mobile radio that operates on its ASTRO 25 systems and will highlight key features enabled by the 7.17 release of ASTRO 25 software today at APCO 2016.

One of the key features of the APX 8500 all-band mobile radio is its ability to leverage LTE connectivity from a VML750 modem installed in the public-safety vehicle, if the ASTRO 25 data capability is interrupted by continuous voice transmissions during a busy incident, according to Anatoly Delm, Motorola Solutions’ director of global infrastructure marketing.

“Let’s say that you have a major incident, everybody’s talking all the time and the ASTRO network is being used all the time, it can [offload] some of the data communications, like GPS, to broadbandâ€"public-safety LTE or commercial LTE, depending on what the modem is operating on,” Delm said during an interview with IWCE’s Urgent Communications.

“So, you’ve got this combination of the best of both worlds, where your voice communications are continuing over the ASTRO network, and your data communicationsâ€"if the ASTRO network is too busy, because of a major incidentâ€"can be carried on by an LTE network from the same car.”



Meanwhile, the 7.17 release of ASTRO 25 software will provide system users and operators with features that are designed to improve the reliability and usability of the P25 network, Delm said.

One enhancement is a more efficient way to execute over-the-air software updates, Delm said.

“Ordinarily, what happens is that the software update has to travel to one radio at a time. If you’ve got a large enough fleet, it could take days or possibly weeks [to complete the software update for all radios],” he said. “In this case, the software is being continuously broadcast, kind of like on repeat. In the meantime, all of the radios continue to function as normalâ€"you can talk on them, and none of the functions are disrupted.

“Once a radio has received all of the packets that it needs, it can then give the user the [a notification] that the update is ready and asks whether the user wants to install it. If they say ‘Yes,’ then the radio is updated. This means you can reduce your update time to maybe a few hours, depending on the size of your fleet. But you certainly don’t have to do it one at a time.”

Other new capabilities included in the latest ASTRO 25 software release include personnel accountabilityâ€"often used for roll-call functionality on a fireground or other incident sceneâ€"over trunked systems, Delm said. Previously, this capability existed only in conventional mode.

The demand for the Wellies increased significantly when World War I started. This is because the army believed that the boots were very durable and they provided ample protection for the soldier's feet even on rough terrain and pilot language translator. After the war, the civilians also began to see the durability of the Wellies and they became more popular not just with the military. Today, it is very common to see at least a pair of Wellies in every household.

If you are lucky, enough to speak two languages from childhood, then you have conquered much of the work that many translators go through. Most have to go to school at least four years to gain an intimate knowledge of their chosen primary language. Some choose to live in a relevant country to gain even more knowledge about the language and culture. For those that have that knowledge from childhood, education is still relevant however. While you may speak a language well, you need to have an intimate knowledge of the written language as well. Many people speak two languages but may only write in one fluently. That many people start their careers with a bit of an advantage.

The sound quality of this gadget is excellent. Also, you get a pair of in-extreme conditions demand extreme responses in the box. Improved S-Pen Stylus is something that you definitely cannot miss out in this phone. It comes with a lot of added features like auto-correct, art package etc. which makes using stylus even easier.

Music From Your Sunglasses? Zungle's Founders Crowdfund $2M For Shades With Bone-Conduction Speakers

Anything with bone conducting technology, we will jump upon and love the hell out of! When we heard about Sunglasses that had speakers with bone conducting inside, to allow you to make calls and listen to music whilst on the move we thought what a great idea. This crowd-funder is looking to raise $50,000 but $1 million would be a good start. See more on this here.

One of the latest hot crowdfunding campaigns is for dark sunglasses called the Zungle Panther with bone-conduction technology that allows them to be used to listen to music and make phone calls. Jason Yang, Zungle’s 30-year-old CEO and co-founder, came up with the idea because he was annoyed with trying to wear an earpiece and sunglasses to listen to music while wakeboarding.

“We all love extreme sports, and Jason is a huge fan of wakeboarding,” says Sean Bang, 30, Zungle’s chief marketing officer and co-founder. “He’ll have sunglasses on, but eventually the earphone doesn’t work with the sunglasses, and he felt that it was inconvenient and uncomfortable. So we decided to get rid of the inconvenience.”

With Zungle’s sunglasses, wearers can listen to music or make phone calls while skiing, biking or wakeboarding without worrying about an additional earpiece. Bone-conduction technology, in which you hear sound through vibrations to your skull rather than through your ears, isn’t new. But the idea of putting it into relatively inexpensive consumer products, like sunglasses, has been gaining traction recently.

So after fiddling with the product for nearly a year, in June, the two friends, who had worked together at marketing firm Innocean Worldwide in South Korea, along with two other cofounders, Chris Hong and Injun Park, turned to Kickstarter with a stated goal of $50,000 for their high-tech sunglasses. As with many crowdfunding campaigns, that $50,000 number was a lowball one; Yang says “about $1 million” was their actual goal. The Zungle Panther has a similar look to Oakley’s shades, and retails for $150. Backers who chipped in $89 could get them in a choice of colors as a “reward.” “When we started, we didn’t have enough money to create this product,” Bang says. “We chose Kickstarter because we can target everyone around the globe.”



By the time the campaign ended, in mid-July, Zungle had raised more than $1.9 million, putting it among Kickstarter’s top 100 campaigns of all-time.
