THE WIRELESS APPLICATION PROTOCOL
The wireless application protocol (WAP) is a collection of protocol standards whose purpose is to enable communication between handheld wireless devices and Internet-based service providers. Mobile devices vary greatly in capability. Some are compact, but fully powerful, computers. These are not the subjects of this chapter. WAP exists to accommodate the limitations of very small devices, generally mobile phones. Limited amounts of memory, both RAM and ROM, impact the performance characteristics of these devices. Applications and utilities, including security elements, must be optimized for the restricted environment. The service providers include Web servers providing content formatted especially for small wireless devices and other service providers who target the wireless devices exclusively.
This set of standards builds on existing standards, reusing or modifying where necessary to address the special ...
