Wireless Application Protocol (WAP) is a wireless protocol that allows mobile devices to use data service and access the Internet. WAP can work with a variety of different wireless technologies, each of which connects at the bottom of the WAP stack as a bearer. Bluetooth simply provides another possible bearer beneath the WAP stack.
In the same way that Bluetooth has the SIG which defines standards and helps to ensure interoperability of Bluetooth devices, WAP has the WAP forum. The WAP forum brings together companies from all parts of the wireless industry to define WAP standards and to help ensure interoperability between WAP products. WAP standards can be downloaded from the WAP forum Web site at
