Helios’ Digital TETRA Repeaters employ Software Defined Radio (SDR) technology based upon our FPGA & DSP Platform. This achieves high out- of-band rejection and high intra-Carrier interference compared to traditional Analog IF SAW filters. It also enables on-the-fly filter change/upgrade by software without an expensive hardware upgrade.
Our TETRA Repeaters help to extend the coverage of Public Safety and Critical Communications Networks. Helios offers complete and integrated solutions for TETRA Networks to ensure coverage of major public infrastructure; such as exhibition halls, airports, sports arenas, road and rail tunnels, hotels, convention centers, shopping malls, office towers, parking garages, wind farms, etc.
