Glossary
Open System
A security option which broadcasts a beacon signal including the access point’s configured SSID. Wireless clients can read the SSID from the beacon, and automatically reset their SSID to allow immediate connection to the nearest access point.
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.
Simple Network Management Protocol (SNMP)
The application protocol in the Internet suite of protocols which offers network management services.
