Abstract:
1. A method, said method comprising: setting an adjustment timer; receiving, by a transmitter, a report from at least one associated client, wherein said report includes data indicating received signal strength, client transmit power level, and at least one of link margin and receiver sensitivity; setting a downlink transmit power level for each of the at least one associated client responsive to said report; using said downlink transmit power level for data transmissions to each of the at least one associated client; upon expiration of said adjustment timer, determining a downlink data loss rate using a number of retransmission requests in a time interval set by said adjustment timer; if said downlink data loss rate is greater than a threshold, adjusting said downlink transmit power level responsive to said downlink data loss rate for each of the at least one associated client; and using a data loss measurement window to maintain status of most recent data transmissions for each of the at least one associated client.
