ABSTRACT:
A transceiver in an ad hoc network may use a rate adaptation module to select an optimal data rate for a given wireless environment. The rate adaptation module may use a measured RSSI (Received Signal Strength Indicator) from a receive section and a retry count from a transmit section to determine the optimal data rate.
