|WAP, Wireless Applications Protocol|
A set of network and application protocols including a datagram protocol (WDP), Transport Layer Security (WTLS), Transaction Protocol (WTP), Session Protocol (WSP), and Application Environment (WAE), which use carrier-based gateways to enable wireless devices to access Web resources.
WAP specifies an application framework and network protocols for wireless devices such as mobile telephones, pagers, and PDAs. The architecture requires a proxy between the mobile device and the server. The WAP protocol stack is layered over a datagram transport service. Such a service is provided by most wireless networks; for example, IS-136, GSM SMS/USSD, and UDP in IP networks like CDPD and GSM GPRS. The core of the WAP protocols is a binary HTTP/1.1 protocol with additional features such as header caching between requests and a shared state between client and server.
