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.
