the delivery of last mile wireless broadband access as an alternative to
cable and DSL."
Wireless router
A stand-alone wireless hub that allows any computer that has a wireless
network adapter to communicate with another computer within the same
network and to connect to the Internet.
WLAN (Wireless
Local-Area Network)
A type of local-area network that uses high-frequency radio waves rather
than wires to communicate between nodes.
WPA* (Wi-Fi
Protected Access)
This is a security enhancement that strongly increases the level of data
protection and access control to a wireless network. WPA is an interim
standard that will be replaced with the IEEE's 802.11i standard upon its
completion. WPA consists of RC4 and TKIP and provides support for
BSS (Infrastructure) mode only. WPA and WPA2 are compatible.
WPA2* (Wi-Fi
Protected Access 2)
This is the second generation of WPA that complies with the IEEE TGi
specification. WPA2 consists of AES encryption, pre-authentication and
PMKID caching. It provides support for BSS (Infrastructure) mode and
IBSS (ad hoc) mode. WPA and WPA2 are compatible.
WPA-Enterprise
Wi-Fi Protected Access-Enterprise applies to corporate users. A new
standards-based, interoperable security technology for wireless LAN
(subset of IEEE 802.11i draft standard) that encrypts data sent over radio
waves. WPA is a Wi-Fi standard that was designed to improve upon the
security features of WEP as follows:
 Improved data encryption through the temporal key integrity
protocol (TKIP). TKIP uses a hashing algorithm to scramble the
encryption keys and adds an integrity-checking feature to ensure
that the keys have not been tampered with.
 User authentication, which is generally missing in WEP, through
the extensible authentication protocol (EAP). WEP regulates
access to a wireless network based on a computer's hardware-
specific MAC address, which is relatively simple to be sniffed out
and stolen. EAP is built on a more secure public-key encryption
system to ensure that only authorized network users can access
the network.
WPA is an interim standard that will be replaced with the IEEE's 802.11i
standard upon its completion.
WPA-Personal
Wi-Fi Protected Access-Personal provides a level of security in the small
network or home environment.
WPA-PSK (Wi-Fi
Protected-Access Pre-
Shared Key)
WPA-PSK mode does not use an authentication server. It can be used
with the data encryption types WEP or TKIP. WPA-PSK requires
configuration of a pre-shared key (PSK). You must enter a pass phrase or
64 hex characters for a pre-shared key of length 256-bits. The data
encryption key is derived from the PSK.
