Protocols for wireless applications

Wireless data networks present a more constrained communication environment compared to wired networks. Because of fundamental limitations of power, available spectrum, and mobility, wireless data networks tend to have less bandwidth than traditional networks, more latency than traditional networks, less connection stability than other network technologies, and less predictable availability.

Mobile devices have a unique set of features that must be exposed in the Web, in order to enable the creation of advanced telephony services that include location-based services, intelligent network functionality, including integration into the voice network, and voice/data integration.

The Wireless Application Protocol (WAP) architecture provides a scalable and extensible environment for application development for mobile communication devices. The WAP protocol stack has a layered design, and each layer is accessible by the layers above, and by other services and applications. The WAP layered architecture enables other services and applications to use the features of the WAP stack through a set of well-defined interfaces. External applications can access the session, transaction, security, and transport layers directly.
