U
UNII Bands: Unlicensed National Information Infrastructure. In contrast to the ISM
bands, these are a group of frequency bands set aside by the FCC for WLAN type
communications only. Users must accept interference from other legal WLAN users, but
the other sources of interference problems are, or legally should be, missing.

W
WEP64 and WEP128: Wired Equivalent Privacy, 64 bit and 128 bit (64 bit is sometimes
referred to as 40 bit). This is a low-level encryption technique designed to give the user
about the same amount of privacy that he would expect from a LAN. It is extremely
important to understand that WEP is not some CIA-proof supercode! It performs as
intended, giving the user a simple level of data security and protection from casual
electronic eavesdropping. Use of the 128 bit option at all possible times is recommended.
Remember that 802.11 devices transmit (broadcast) in all directions, and that it is
possible, with very complex software, to copy and decode WEP transmissions. The task
is not trivial, but it is possible. If your data is extremely sensitive, you should consider
some form of secondary protection, such as strong passwords and an additional level of
encryption. Suitable software packages are available from reputable suppliers. Although
not intended by the original architects, WEP also helps prevents unauthorized access to
your system by an outsider. Hackers have been known to access systems from outside a
building, and to then to access the Web for a leisurely session, all at the system owner’s
expense.

Wide Area Network (WAN): A wide area network (WAN) is a voice, data, or video
network that provides connections from one or more computers or networks within a
business to one or more computers or networks that are external to such business.
network that provides connections from one or more computers or networks within a
business to one or more computers or networks that are external to such business.
Wireless: A microwave transceiver system.
Wireless LAN (WLAN): Wireless LAN is a type of local-area network that uses high-
frequency radio waves rather than wires to communicate between nodes. WLAN is a
flexible data communication system used as an alternative to, or an extension of a wired
LAN.

Wireless Node: A user computer with a wireless network interface card (adapter).
