rotocol) A standard for providing cellphones, pagers and other handhelds with secure access to email 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.
