APs transmit a beacon management frame at fixed intervals. To associate with an access point and join a BSS, a client listens for beacon messages to identify the access points within its range. The client selection of which BSS to join is carried out in a vendor independent manner. A client may also send a probe request management frame to find an access point associated with the desired SSID (service set identifier. Multiple infrastructure BSSs can be combined via their uplink interfaces to form a single sub network referred to as an ESS topology. It is thus possible to expand the wireless network with a number of AP’s utilising the same channel or utilise different channels to boost aggregate throughput.
