TKPIL:

Transceiver: A commonly used term that describes a combination transmitter and receiver. Both

802.11a and 802.11b devices would be properly described as data transceivers.

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.

WECA: The Wireless Ethernet Compatibility Alliance...

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 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):

Wireless: A microwave transceiver system.

Wireless LAN (WLAN):

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