Definition
The Wireless Application Protocol（WAP）is a set of open, global protocols for developing applications and services that use wireless networks. The WAP protocols are mainly based on already existing Internet protocols, but are optimized for mobile users with wireless devices.
History
Ericsson, Nokia and many others began developing standards independently of each other, but soon they realized that it would make more sense to focus development around a common standard.They all wanted to establish a common format for Internet transfers to mobile telephones, without having to customize the Internet pages for the particular display on every different mobile telephone or personal organizer.With WAP Forum they were able to find such a protocol.
