"Wireless Application Protocol (neelam) is an open international standard for applications that use wireless communication (for example, Internet access from a mobile phone). WAP was designed to provide services equivalent to a web browser with some mobile-specific additions, being specifically designed to address the limitations of very small portable devices. It is now the protocol used for the majority of the world's mobile Internet sites, otherwise known as wap-sites (WAPsites, WAP sites, wapsites, etc.)."
