Wireless Application Protocol (WAP)

WAP was the first widely deployed set of standards for the Web on mobile. WAP is actually a suite of standards that cover both the page markup format (WML) and the protocols used to serve it (WTP, WTLS etc.) The WAP standards suite is managed by the Open Mobile Alliance (OMA).
There have been two major evolutions of WAP.

WAP 1.0 was the dominant standard in the earlier days of the Mobile Web and nearly all mobile service providers and mass-market mobile phones in North America and Europe retain support for at least WAP 1.0.

WAP 2.0 is the current version of the standard. One of the major goals of WAP 2.0 was to bring mobile devices closer to the desktop by adopting the following changes:

• Support for the standard Internet communication protocols such as TCP/IP and HTTP rather than the proprietary protocols used by WAP 1.0.
• Adoption of XHTML-MP as the primary markup language.
