Term Definition

W-CDMA Officially known as IMT-2000 direct spread; ITU standard derived from

Code-Division Multiple Access (CDMA). Wideband code-division multiple

access (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.

WEP Wired equivalent privacy (WEP) is 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 network In a Wireless LAN (WLAN), laptops, desktops, PDAs, and other computer

peripherals are connected to each other without any network cables.

These network elements or clients use radio signals to communicate with

each other. Wireless networks are set up based on the IEEE 802.11

standards.

WISP Wireless ISP (WISP) refers to 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 stations, to

access the Internet and the Web from anywhere within the zone of

coverage provided by the server antenna, usually a region with a radius of

several kilometers.

wireless service provider A company that offers transmission services to users of wireless devices

through radio frequency (RF) signals rather than through end-to-end wire

communication.

WLAN Wireless local area network (WLAN) is a local area network (LAN) that the

users access through a wireless connection.
