SSID
Service Set Identifier, a 32-character unique identi-
fier attached to the header of packets sent over a
WLAN that acts as an identifier when a mobile
device tries to connect to the BSS. An SSID is also
referred to as a network name because essentially
it is a name that identifies a wireless network.
The SSID differentiates one WLAN from another, so
all devices attempting to connect to a specific
WLAN must use the same SSID. A device will not
be permitted to join the BSS unless it can provide
its unique SSID. Because an SSID is present as
plain text in the packets, it does not supply any
security to the network.
