The Hytera TETRA iBS Base Station operates across 50 kHz.
Receiver sensitivity is –120 dBm (BER 4%). Sensitivity states how weak a signal the radio can still decode, and a lower number is better. At the edge of coverage it determines range as much as transmit power does — communication usually fails not because the other party cannot hear, but because the radio cannot decode a weak signal.
Ingress protection is IP66. IP67 and above means the device withstands immersion in one metre of water. The rating only holds if the fitted battery and the accessory jack cover carry the same class; a standard battery lowers the protection of the whole assembly.
Operating temperature range is –40°C ~ +60°C.
Location support is GPS. Where position reporting will be used, the antenna has to be chosen for it as well: fit an antenna that does not cover the GPS band at 1575 MHz and the radio will communicate perfectly while showing no position on the dispatch screen.
