Term	Definition
	spectrum of frequency bands with very low power for a short distance. Ultra
	wideband broadcasts very precisely timed digital pulses on a carrier signal across
	a very wide spectrum (number of frequency channels) at the same time. UWB can
	carry a huge amount of data over a distance up to 230 feet at very low power (less
	than 0.5 milliwatts), and has the ability to carry signals through doors and other
	obstacles that tend to reflect signals at more limited bandwidths and a higher
	power.
virtual private network (VPN)	A network that uses a public telecommunication infrastructure, such as the
	Internet, to provide remote offices or individual users with secure access to their
	organization's network. A VPN ensures privacy through security procedures and
	tunneling protocols such as the Layer Two Tunneling Protocol ( L2TP ). Data is
	encrypted at the sending end and decrypted at the receiving end.
voice over WLAN (VoWLAN)	A method of routing telephone calls for mobile users over the Internet using the
	technology specified in IEEE 802.11b. Routing mobile calls over the Internet makes
	them free, or at least much less expensive than they would be otherwise.
wideband code-division multiple	Officially known as IMT-2000 direct spread; ITU standard derived from Code-
access (W-CDMA)	Division Multiple Access (CDMA). W-CDMA is a third-generation (3G) mobile
	wireless technology that promises much higher data speeds to mobile and
	portable wireless devices than commonly offered in today's market.
Wi-Fi	A term for certain types of WLANs. Wi-Fi can apply to products that use any 802.11
	standard. Wi-Fi has gained acceptance in many businesses, agencies, schools,
	and homes as an alternative to a wired LAN. Many airports, hotels, and fast-food
	facilities offer public access to Wi-Fi networks.
WiMAX	A wireless industry coalition whose members organized to advance IEEE 802.16
	standards for broadband wireless access (BWA) networks. WiMAX 802.16
	technology is expected to enable multimedia applications with wireless
	connection and, with a range of up to 30 miles, enable networks to have a wireless
	last mile solution. According to the WiMAX forum, the group's aim is to promote
	and certify compatibility and interoperability of devices based on the 802.16
	specification, and to develop such devices for the marketplace.
wired equivalent privacy (WEP)	A security protocol specified in 802.11b, designed to provide a WLAN with a level
	of security and privacy comparable to what is usually expected of a wired LAN.
	Data encryption protects the vulnerable wireless link between clients and access
	points; once this measure has been taken, other typical LAN security mechanisms
	such as password protection, end-to-end encryption, virtual private networks
	(VPNs), and authentication can be put in place to ensure privacy.
wireless	Describes telecommunications in which electromagnetic waves (rather than some
	form of wire) carry the signal over part or all of the communication path.
wireless abstract XML (WAX)	Describes telecommunications in which electromagnetic waves (rather than some
	form of wire) carry the signal over part or all of the communication path.
wireless application service	Provides Web-based access to applications and services that would otherwise
provider (WASP)	have to be stored locally and makes it possible for customers to access the service
	from a variety of wireless devices, such as a smartphone or personal digital
	assistant (PDA).
wireless ISP (WISP)	An internet service provider (ISP) that allows subscribers to connect to a server at
	designated hot spots (access points) using a wireless connection such as Wi-Fi.
	This type of ISP offers broadband service and allows subscriber computers, called
