beacon, and automatically reset their SSID to allow immediate connection 

to the nearest access point.

Orthogonal Frequency Division Multiplexing: OFDM allows multiple users to 

transmit in an allocated band by dividing the bandwidth into many narrow 

bandwidth carriers.

Service Set Identifier: 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 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.

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 Time Protocol: SNTP allows a device to set its internal 

clock based on periodic updates from a Network Time Protocol (NTP) 

server. Updates can be requested from a specific NTP server, or can be 

received via broadcasts sent by NTP servers.

Temporal Key Integrity Protocol: A data encryption method designed as a 

replacement for WEP. TKIP avoids the problems of WEP static keys by 

dynamically changing data encryption keys.

Trivial File Transfer Protocol: A TCP/IP protocol commonly used for software 

downloads.

Virtual Access Point: Virtual AP technology multiplies the number of Access 

Points present within the RF footprint of a single physical access device. 

With Virtual AP technology, WLAN users within the device.s footprint can 

associate with what appears to be different access points and their 

associated network services. All the services are delivered using a single 

radio channel, enabling Virtual AP technology to optimize the use of limited 

WLAN radio spectrum.

WPA employs 802.1X as its basic framework for user authentication and 

dynamic key management to provide an enhanced security solution for 

802.11 wireless networks.
