Belgian emergency and security services once again rely on Airbus Defence and Space’s Tetra.

With a huge amount of information on the internet about Walkie talkie’s it can be hard to discover the top and largely truthful information. here is a piece of writing from a good site that i believe to be factual, do not quote me on it but please read and enjoy
 Astrid continues to invest in Tetra technology to guarantee users uninterrupted network performance and quality service
A consortium composed of Airbus Defence and Space and Belgacom has been awarded a major renewal contract for the Belgian nationwide Tetra network. It aims to strengthen crucial components of the core network and will provide more efficient system management and additional security. The network, called Astrid, currently serves about 56,000 users from all public safety and security services (police, fire, health and ambulance services), and several utility and transport companies in Belgium.
 
To guarantee its users uninterrupted network performance and quality service, the network operator, also called Astrid, has drawn up the renewal plan, which will start with the replacement of the core network infrastructure and monitoring systems. The contract covers the exchange of eleven provincial switches (DXT), the optimisation of the architecture, and the evolution of the technology to IP (Internet Protocol). As the brain of the radio network, the switches handle the routing of all Walkie talkie communications and identify the radio position.
 
Daniel Haché, Director of External Relations at Astrid, highlights the importance of the contract: “Belgian emergency and security services rely heavily on the communications systems provided by Astrid. For us, Tetra remains the very best technology for mobile voice communications in the public safety sector. This renewal contract clearly shows that besides the launch of the 3G data service via Blue Light Mobile, Belgium will continue to work with Tetra and is still investing in this technology.”
 
Nicole Lecca, Head of Secure Land Communications at Airbus Defence and Space, said: “This new contract with our longstanding customer Astrid illustrates that Tetra will remain an essential asset for mission-critical voice communications in the next decade. We are continuing our development efforts in this technology as an integral part of our solutions portfolio for secure communications.”

I recently started watching NASCAR and I was wondering how the drivers communicate with the pit crew

Article of the Day………ok so i don’t have a piece of writing seven days a week, but when i get a chance I’ll post articles I find fascinating. Lucky enough here’s one of those articles that I read and needed to share. Should you enjoy it as much as me, please add one of the special social media likes, you know the one which tells everybody that you enjoyed something, rather then you sat on your arse and watched Television!

two way radio appNASCAR drivers use a unique radio system that is built in to their crash helmets. These are occasionally customized to suit the individual wearer. In addition to this, there is a push-to-talk button (exactly like the one found on a walkie-talkie), which is situated in the steering wheel. A wiring harness connects the various components together and a separate battery operates the whole thing. The signal is broadcast via a whip antenna that is attached to the roof of the car. In this fashion, NASCAR drivers are able to communicate with pit crews.

In addition to this, most cars are outfitted with a spare Motorola two-way radio that is within easy reach of the driver.

A firm out of Atlanta, Georgia named ‘Racing Radios’ provides the vast majority of the radios used in NASCAR races. Racing Radios have provided equipment to NASCAR races for 30 years or so; they are a trusted firm, creating all the standard NASCAR radio technology and also providing custom radios/peripherals for individual drivers.

According to Racing Radios spokesperson Tony Cornacchia, the majority of NASCAR drivers prefer to buy their own specialized equipment from the firm.

Because so many teams are racing and so many people are working on the race overall, it is not uncommon for NASCAR events to feature 100 FCC licensed radio broadcasts at any given time.

Racing Radios is the company that programs the individual frequencies, not only for drivers and pit crews, but also for staff, officials and security personnel. RR do such a good job, that neither drivers nor pit crews suffer regularly from interference or dead spots. Now that’s something.

According to Terry Boyce of ‘HowStuffWorks’, “Many teams outfit their entire pit and support crews with custom-engineered, hand-built headphones and Walkie Talkies ordered through Racing Radios. Multi-car teams may choose to connect even more people through their radio communications network. Active Noise Reduction (ANR) technology helps to cancel out distracting background noise. Exceptional communication is one of the reasons a 21st century NASCAR pit crew can change four tires and refuel a race car in around 13 seconds — and do it 10 or more times in a single race”.
