Table 88: List of Terms Term W-CDMA Wi-Fi WEP wireless wireless network WISP wireless service provider WLAN Definition 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. 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. 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. Describes telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path. 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. 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. A company that offers transmission services to users of wireless devices through radio frequency (RF) signals rather than through end-toend wire communication. Wireless local area network (WLAN) is a local area network (LAN) that the users access through a wireless connection.
