The SSID, BSSID and MAC address are all
essential unique identifiers for a wireless network. The Service Set
Identifier (SSID) is the human readable name associated with an 802.11
wireless network. It is often called the wireless “network name” and can
be shared by multiple access points. The Basic Service Set Identifier
(BSSID) uniquely identifies a specific access point and is in the same
format as a MAC address; thus, most commonly, it is the MAC address of
the access point. The Extended Service Set Identifier (ESSID) can
essentially be thought of as a group of BSSIDs that share the same Layer
2 network and the same SSID.
