WAP: Wireless Application Protocol
The Wireless Application Protocol (WAP) refers to a group of related technologies and protocols widely used as a de facto standard protocol in providing Internet access to mobile phones or other thin-client devices. Typical use of the WAP protocol involves a website transmitting scaled-down versions of normal web pages specifically optimized for use by wireless telecommunications devices. When used with Wireless Markup Language (WML), for example, hyperlinks can be accessed by the numbers of 0 through 9 in addition to assigned hotkeys on a user's phone.
