Abstract:
1. A method for performing a relative signal strength indicator (RSSI) training process, the method comprising: determining a packet transmission rate for transmitting an available packet; transmitting the packet at the determined transmission rate; performing an RSSI training process based on the transmitted packet; based on a condition that an acknowledgement (ACK) message is received in response to the transmitted packet, determining an RSSI level of an RSSI measurement of the ACK message and incrementing a count of total packet transmissions for the RSSI level; and based upon the count of total packet transmission ACK messages, updating a preferred packet transmission rate for the RSSI level; based on a condition that an ACK message is not received in response to the transmitted packet, increment a count of errors for the RSSI level, update a preferred packet transmission rate for the RSSI level, and adjust the transmission rate for packets by using a vector configured to trigger a rate decrease by a predetermined number of transmission rate levels.
