secure transmission and authentication is particularly important to users unknown to each other. The 
authentication capability defined in the specification enables a secure access control mechanism for the 
service providers and for mobile users not utilizing VPN connections. 

Wi-Fi Protected Access in "Mixed Mode" Deployment 

In a large network with many clients, a likely scenario is that access points will be upgraded before all the 
Wi-Fi clients. Some access points may operate in a "mixed mode", which supports both clients running 
Wi-Fi Protected Access and clients running original WEP security. While useful for transition, the net effect 
of supporting both types of client devices is that security will operate at the less secure level (WEP), 
common to all the devices. Therefore, organizations will benefit by accelerating the move to Wi-Fi Protected 
Access for all Wi-Fi clients and access points. 

WiMAX 

An IEEE 802.16 Task Group that provides a specification for fixed broadband wireless access systems 
employing a point-to-multipoint (PMP) architecture. Task Group 1 of IEEE 802.16 developed a 
point-to-multipoint broadband wireless access standard for systems in the frequency range 10-66 GHz. The 
standard covers both the Media Access Control (MAC) and the physical (PHY) layers. Ratification is 
expected in second half of 2004. 

Wireless Multimedia (WMM)

WMM (Wireless Multimedia) is a subset of the 802.11e standard. WMM allows wireless traffic to have a 
range of priorities, depending on the kind of data. Time-dependent information, like video, audio, or voice 
will have a higher priority than normal traffic. For WMM to function correctly, wireless clients must also 
support WMM. 

Wireless Networking 

Wireless Networking refers to the infrastructure enabling the transmission of wireless signals. A network 
ties things together and enables resource sharing. 

WLAN (Wireless LAN) 

Also referred to as LAN. A type of local-area network that uses wireless or high-frequency radio waves 
rather than wires to communicate between nodes.
