access point’s configured SSID. Wireless clients can read the
SSID from the beacon, and automatically reset their SSID to

Orthogonal Frequency Division Multiplexing (ODFM)
OFDM/ allows multiple users to transmit in an allocated band by
dividing the bandwidth into many narrow bandwidth carriers.
RTS Threshold
Transmitters contending for the medium may not be aware of
each other. RTS/CTS mechanism can solve this “Hidden Node
Problem.” If the packet size is smaller than the preset RTS
Threshold size, the RTS/CTS mechanism will NOT be enabled.
Service Set Identifier (SSID)
An identifier that is attached to packets sent over the wireless
LAN and functions as a password for joining a particular radio
cell; i.e., Basic Service Set (BSS).
Session Key
Session keys are unique to each client, and are used to
authenticate a client connection, and correlate traffic passing
between a specific client and the access point.
Shared Key
A shared key can be used to authenticate each client attached to
a wireless network. Shared Key authentication must be used
along with the 802.11 Wireless Equivalent Privacy algorithm.
