W-CDMA
Wideband Code Division Multiple Access, one of two 3G standards that makes use of a wider spectrum than CDMA and therefore can transmit and receive information for faster and more efficiently. Co-developed by NTT DoCoMo, it is being backed by most European mobile operators and is expected to compete with cdma2000 to be the de facto 3G standard.

W-TDMA
Wideband-Time Division Multiple Access, a technique based on time division transmission which is similar to that used by GSM but provides a much higher transmission rate. It was submitted as a solution for UMTS radio interface, but was rejected.

W3C
World Wide Web Consortium. World Wide Web Consortium - Web Standards

WAE (Wireless Application Environment)
WAE specifies an environment that allows operators and service providers to build applications and services that can reach a wide variety of different platforms. WAE is part of the Wireless Application Protocol.

Walsh code
Is one of 64 chip patterns which are 64 chips long. CDMA channels are differentiated by which Walsh code they use. They are carefully chosen to be orthogonal to each other.

WAN
Wide Area Network. A general term referring to a large network spanning a country or around the world. The Internet is a WAN. A public mobile communication system is a WAN.

WAP (Wireless Application Protocol)
WAP is a family of protocols allowing mobile devices to access wireless services.. The development of WAP is being driven by the WAP Forum, initially founded by Motorola, Nokia, Ericsson and Unwired Planet. WAP is a technology designed to provide users of mobile terminals with limited access to the Internet. It offers information in text form on the screen of your phones, but it’s hardly the World Wide Web.

WAP Forum
WAP Forum, an organization of several big Internet and telecom companies, develops the WAP protocol. WAP Forum

WAP Gateway
A WAP gateway is two-way software. Its main function is to offload the WAP mobile device from a lot of computational layers.

WAP Server
A WAP server is a web server. The computer programmers use WML instead of HTML.

WCDMA (Wideband Code Division Multiple Access)
A technology for wideband digital radio communications of Internet, multimedia, video and othersWideband Code Division Multiple Access, one of two 3G standards that makes use of a wider spectrum than CDMA and therefore can transmit and receive information for faster and more efficiently. Co-developed by NTT DoCoMo, it is being backed by most European mobile operators and is expected to compete with cdma2000 to be the de facto 3G standard.

WCDMA-DS
see DS-WCDMA

Whip
The vertical portion of the antenna assembly, which acts as the radiator of the radio frequency energy.

Wideband
A classification of the information capacity or bandwidth of a communication channel. Wideband is generally taken to mean a bandwidth between 64kbits/s and 2Mbit/s.

Wireless
A new all-encompassing “buzzword” which describes what used to be called “radio”, but which typically also implies some of the newer cellular or digital radio technologies as well.

Wireless Access
A terminal access to the network that uses wireless technology.

Wireless Telemetry
Wireless Machine-to-Machine (M2M) communication, not including traditional data or voice-centric devices. Examples of wireless telemetry applications include: asset tracking, point-of-sale, vending, arcade games, supervisory control and data acquisition (SCADA

Wireless Transceiver
A wireless device, typically a modem, which transmits M2M data from the unit being monitored to a control room where it can become useful information.

Wireline
Wireline and Non-Wireline are terms used to distinguish between the two cellular carriers in a CGSA. Originally, the “wireline” carrier was an affiliate of a telephone company providing conventional landline telephone service within the area of the CGSA; the “non-wireline” carrier was the other cellular operator. In recent years, the terms simply denote whether the carrier uses the “A” block of cellular frequencies (non-wireline) or the “B” block (wireline). All cellular telephones sold in the United States must be able to use both A and B block cellular channels.

WISP
Wireless Internet Service Provider.

WLAN
Wireless Local Area Network. A short-range computer-to-computer wireless data communications network.

WMAN
Wireless Metropolitan Area Network. A regional wireless computer or communication network spanning the area covered by an average to large city.

WML
Wireless Markup Language. Wireless Markup Language is a markup language developed specifically for wireless applications. WML is based on XML.

WML Card
A WML card must exist inside a WML deck containing one or more cards.

WML Deck
A collection of WML cards.

WMLScript
Scripting language for WAP devices. Based on JavaScript, but less powerful.

WPAN
Wireless Personal Area Network - Bluetooth Technology

WSP (Wireless Session Protocol)
Provides the upper-level application layer of WAP with a consistent interface for two session services, a connection-mode service that operates above a transaction layer protocol, and a connectionless service that operates above a secure or non-secure datagram transport service.

WTLS (Wireless Transport Layer Security)
WTLS is the “equivalent” to SSL (Secure Sockets Layer) widely used in the HTML world - although not identical in functionality.

WTP
Wireless Transaction Protocol

WWAN
Wireless Wide Area Network. WWAN uses various devices - telephone lines, satellite dishes, and radio waves - to service in area broader than can be covered by a WLAN, although typically with lower bandwidth.

WYSIWYG
What You See Is What You Get.

XML (Extensible Markup Language)
W3C’s standard for Internet Markup Languages. WML is one of these languages.

Yagi
A directional, gain type of antenna that utilizes a number of parasitic directors and a reflector. Named after one of the two Japanese inventors (Yagi and Uda).

Zone
Refers to one or more sectors of one or more cells. It is an administrative category in CDMA. Movement within a zone does not require the phone to reregister. The phone has to register if it crosses a zone boundary.
