La description
Helios® Public Safety Digital Single Band 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.
Helios® Public Safety equipment helps to extend the coverage of Public Safety and Critical secure Communications Networks. Helios offers complete and integrated solutions for TETRA, DMR, PMR, P25 and LTE Networks to ensure coverage of major public infrastructure; such as police stations, garages, power plants, exhibition halls, airports, sports arenas, road and rail tunnels, hotels, convention centers, shopping malls, office towers, parking lots etc.
