摘要: An adaptive power control used on a radio network and method for adaptively controlling the transmit level of member stations network. exemplary (12) includes plurality (10a through 10f) between which signal propagation conditions are subject to change. Each station transceiver (21) having transmitter (26) receiver (28) section. The is controlled by variable gain circuit (48) in response produced (34). A uses determined reference database signal-to-noise ratio (SNR) data defining quality each communication link levels last pair stored. If transmission an initial frame not received next frame, (server) incrementally increases its PD successive frames, until either or has failed respond at maximum level, Pmax. indicates that with SNR excess predetermined margin, server reduces ensure minimum used.
