Terrestrial Trunked Radio, or TETRA, is a standard for radio communications. Until recently, designing and operating a trunked system based on this standard was prohibitively difficult without using a dedicated commercial base station. Such equipment was often expensive and difficult to acquire.
Building on research and developmet work by MidnightBlueLabs, new projects have been released and TETRA has become much easier to deploy and use.
In this talk we will introduce some of the basic concepts of radio communications, digital communications, share our experience with developing software for radios using TETRA, some of the legal hoops we had to go through, and we will even have a short demo.
This talk will cover a lot of technical subjects, but no previous experience is expected.
