A wireless intrusion prevention system (WIPS) operates at the Layer 2 (data link layer) level of the Open Systems Interconnection model. WIPS can detect the presence of rogue or misconfigured devices and can prevent them from operating on wireless enterprise networks by scanning the network’s RFs for denial of service and other forms of attack.

Consumer electronics industry special interest group set up to define a next-generation standard for a wireless digital interface for streaming high-definition (HD) content among source devices and HD displays. The first version of WiHD aims to achieve 4 Gbps data rates using the unlicensed 60GHz frequency band.

Certification mark issued by the Wi-Fi Alliance to certify that a product conforms to the 802.11b, g and a standards for WLANs.
Industry:Technology
Now known as the Wi-Fi Alliance. See Wi-Fi and Wi-Fi Alliance.
Industry:Technology
Enables WAP to be bearer-independent by adapting the transport layer of the underlying bearer service and presenting a consistent data format to the higher layer of the WAP protocol stack.
Industry:Technology
Wireless Data Communication is a form of communication that uses the radio spectrum rather than a physical medium. It may carry analog or digital signals and may be used on LANs or WANs in one- or two-way networks.
Industry:Technology
Mobile wireless broadband service for handsets and laptops first offered commercially in South Korea in June 2006 by KT and SK Telecom. WiBro was originally intended as a South Korean standard, but it has been harmonized with the IEEE 802.16-2005 mobile WiMAX standard. WiBro emerged from a South Korean MIC-sponsored project to develop a standard for high-speed portable Internet (HPi). The former MIC had hoped that HPi would lead to new global opportunities for South Korean industry, similar to those arising from its early adoption of CDMA.
Industry:Technology
Vendor that provides hosted wireless applications so that companies do not have to build their own sophisticated wireless infrastructure.
Industry:Technology
Open, global specification that enables users of wireless devices to access and interact with wireless information services and applications. WAP specifications are based on Internet standards, with extensions to reflect the wireless device environment. Specifications in WAP architecture are arranged in a protocol stack consisting of application, session, transaction, security and transport layers. The application layer includes WML and WMLScript for content and Wireless Telephony Application Interface (WTAI) for telephony service capabilities.
Industry:Technology
A server-based gateway that provides wireless access to enterprise applications. WAGs plug into the enterprise’s application infrastructure, separating the data from the presentation layer and avoiding redundant development efforts. Leading WAGs provide secure access to any data source and the ability to render the data to any device (e.g., PDA, wireless telephone, pager or desktop). A WAG server can be deployed either as an internal platform installed within the enterprise, or as an outsourced platform hosted by a third party operating as a service bureau.
