WAP

(1) (Wireless Access Point) See access point.

(2) (Wired Access Point) See wired access point.

(3) (Wireless Application Protocol) A standard for providing cellphones, pagers and other handhelds with secure access to e-mail and text-based Web pages. Introduced in 1997 by Phone.com, Ericsson, Motorola and Nokia, WAP provides an environment for wireless applications that includes a wireless version of TCP/IP and a framework for telephony integration such as call control and phone book access. Supporting keypad and voice recognition, WAP is independent of the air interface and runs over all major wireless networks. It is also device independent and can be used in any mobile device.

WML, WMLScript and XHTML
WAP introduced the Wireless Markup Language (WML), a streamlined version of HTML, and WMLScript, a compact form of JavaScript that runs in limited memory. WML later evolved into mobile versions of XHTML, which, along with all WAP protocols, are governed by the Open Mobile Alliance, the successor to the WAP Forum (see OMA).

WAP and SMS = MMS
The multimedia messaging system (MMS) uses both the SMS text messaging and WAP protocols to transmit graphics, audio and video to cellphones (see MMS). See WTLS, XHTML, HDML, Openwave and i-mode.
