A standard for providing cellular telephones, pagers, and other handheld devices with secure access to e-mail and text-based Web pages. Introduced in 1997 by Phone.com, Ericsson, Motorola, and Nokia,
WAP provides a complete environment for
wireless applications that includes a
wireless counterpart of TCP/IP and a framework for telephony integration, such as call control and telephone book access.
WAP features the
wireless markup language (WML), which was derived from Phone.com’s HDML and is a streamlined version of HTML for small-screen displays. It also uses WMLScript, a compact JavaScript-like language that runs in limited memory.
WAP also supports handheld input methods, such as a keypad and voice recognition. Independent of the air interface,
WAP runs over all the major
wireless networks in place now and in the future. It is also device-independent, requiring only a minimum functionality in the unit to permit use with a myriad of telephones and handheld devices.
