Chelton has the largest installed base of airborne TETRA in the world. We started by supplying the UK, but today have international users of our TETRA systems as it gained foothold in Europe and continued to become a worldwide standard. Our TETRA radio is adapted to allow it to be used across different regions and public safety sectors, all of which are still in use today in the UK, US and in many other countries around the world.
All good things must come to an end and although reliable, TETRA is limited in its capability and ageing. While durable and consistent, TETRA is not able to solely deliver the high standard of voice as well as multimedia data communications to emergency services. Most other countries, especially in Europe, are continuing to use TETRA but those who don’t currently use TETRA are investigating other technologies such as LTE.
Great Britain is one of the countries moving to integrate 4G LTE into the Emergency Services Network (ESN).
4G LTE, or Long Term Evolution, was not originally conceived to be a mission critical communications platform but is the leading candidate to fill the void of the design and bandwidth limitations of TETRA and P25. You are probably already aware that 4G LTE is fast with your mobile but what does that mean for public safety users? Essentially, it provides a smartphone-like capability to users for quicker uploads and downloads, increased coverage and better data transmission whilst also supporting Mission Critical Push to Talk (MCPTT) voice functionality.
And we're on contract with the UK home office to supply it! Read more.
