Abstract: Transmission (Tx) power variation mitigation for Received Strength of Signal Indicator (RSSI) location may be provided. RSSI data for a station may be received from a plurality of Access Points (APs). The RSSI data may include a RSSI value determined from a Block Acknowledgement (BA) packet and a Starting Sequence Number (SSN) and a bitmap of the BA packet. The plurality of APs may be clustered into one or more clusters based on a combination of the SSN and the bitmap. One or more APs having a same combination of the SSN and the bitmap are clustered into one cluster. A probable location of the station may be determined in each of the one or more clusters based on RSSI values received from the one or more APs of each of the one or more clusters. A final location of the station may be determined based on merging probable locations from the one or more clusters.
