A
generic 802.11 AP, at the simplest level, is nothing more than an 802.11
MAC-layer radio that bridges WLAN clients to a wired network based on
association to a Basic Service Set Identifier (A)
The 802.11 standard extends the single AP concept (above) to allow multiple APs to provide an extended service set (ESS), where multiple APs use the same ESS identifier (ESSID, commonly referred to as an SSID) to allow a WLAN client to connect to a common network via more than one AP (B)
A key component of the LWAPP protocol is the concept of split MAC, where part of the 802.11 protocol operation is managed by the LWAPP AP, while the remaining parts are managed by the WLC. (C)
