ABSTRACT:
A high data rate communication system that employs an adaptive sectored antenna is disclosed. The high data rate communication system includes an antenna subsystem for receiving and transmitting data. The antenna subsystem is adapted to be spatially steered. A radio frequency transceiver that is coupled to the antenna subsystem and that selectively generates a bit error rate (BER) signal and a receive signal strength indication (RSSI) signal based upon a received antenna training sequence is also provided. The system also includes a beam steering state machine that is coupled to the radio frequency transceiver and that selectively generates a BER.sub.-- PASS signal and an RSSI.sub.-- PASS signal based upon whether the BER signal is in a first logical relationship with a predetermined BER signal and the RSSI signal is in a second logical relationship with a predetermined RSSI signal. An antenna controller is coupled to the antenna subsystem and the beam steering state machine and selectively generates antenna control signals to spatially steer the antenna subsystem based upon the BER.sub.-- PASS signal and the RSSI.sub.-- PASS signal.
