In a wireless network, such as an 802.11 conformant wireless LAN, a wireless station selects an access point, e.g., during power-up or roaming, based on the received signal strength indicator (RSSI) and channel loading information. The RSSI information is measured by the receiving station when the beacon or probe response frame is received, and the channel loading information is communicated to the station through the beacon or probe response frames. The channel loading information is a percentage of time the access point is busy transmitting or receiving data during a reporting interval. By using both RSSI and channel loading information, performance is increased when the access point with the strongest signal is also the busiest. In this case, this access point would not be selected for association with the wireless station.
