Wireless ATM network (W-ATM) was a concept of using wireless as physical layer to transmit ATM cells. This concept never took off.

is the length of one complete wave of an alternating or vibrating phenomenon, generally measured from crest to crest or from trough to trough of successive waves.

Wireless Bitmap (WBMP) is WAP graphic format optimized for mobile computing devices. A WBMP image is identified using a TypeField value, which describes encoding information (such as pixel and palette organization, compression, and animation) and determines image characteristics according to WAP documentation.

Wideband Wideband-Code Division Multiple Access(W-CDMA or WCDMA), also known as UMTS in Europe, is a 3G standard for GSM in Europe, Japan and the United States. It's also the principal alternative being discussed in Asia. It supports very high-speed multimedia services such as full-motion video, Internet access and video conferencing. It uses one 5-MHz channel for both voice and data, offering data speeds of up to 2 Mbps.

Wireless Data Forum (WDF) is an industry group based in New Zealand dedicated to promote and educate New Zealand companies on many options and solutions available to them through the use of Wireless Data.

The Wireless Datagram Protocol (WDP), a protocol in WAP architecture, covers the Transmission Layer Protocols in an Internet model. As a general transport service, WDP offers to the upper layers an invisible interface independent of the underlying network technology used. In consequence of the interface common to transport protocols, the upper layer protocols of the WAP architecture can operate independent of the underlying wireless network. By letting only the transport layer deal with physical network-dependent issues, global interoperability can be acquired using mediating gateways.

Wireless Ethernet Compatibility Alliance (WECA) is the former name of the Wi-Fi Alliance of vendors promoting 802.11 wireless networking standards and compatibility.

Wireless Distribution System (WDS) is a technology that enables access points to communicate with one another in order to extend the range of a wireless network. WDS is appearing in 802.11g-based access points.

Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b, that is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN. WEP is based on a security scheme called RC4 that utilizes a combination of secret user keys and system-generated values. The original implementations of WEP supported the so-called 40-bit encryption, having a key of length 40 bits and 24 additional bits of system-generated data (64 bits total). Research has shown that 40-bit WEP encryption is too easy to decode, and consequently product vendors today employ 128-bit encryption (having a key length of 104 bits, not 128 bits) or better.

WiBro, standing for Wireless Broadband, is a wireless broadband internet technology being developed by the Korean telecoms industry. In February, 2002, the Korean government allocated 100 MHz of electromagnetic spectrum in the 2.3 GHz band, and in late 2004, WiBro Phase 1 was standardized by the TTA (Telecommunications Technology Association) of Korea.
