WAP

A suite of protocols and specifications designed to enable mobile devices to access internet content and services. WAP defined standards for how mobile devices communicate with web servers, including markup languages (WML, XHTML-MP) optimized for small screens and limited bandwidth. While largely superseded by modern mobile browsers capable of rendering full HTML5, WAP was historically significant in establishing that mobile web access required specific consideration of device constraints — the same constraints that overlap substantially with accessibility requirements for users of assistive technologies.
