This document provides an overview of the Wireless Application Protocol (WAP) which enables delivery of internet content and services to mobile devices. WAP uses open standards like HTML, XML and TCP/IP adapted for wireless networks through specifications for WML, WMLScript and WTAI. A key component is the WAP Gateway that connects the wireless domain to the internet and compresses content using a binary version of HTTP called WSP. The Wireless Markup Language (WML) is used to develop optimized mobile applications that can be efficiently encoded for transmission. WAP enables core mobile services like banking, shopping and messaging through standardized access across different wireless networks and devices.

2. Introduction
 WAP – Wireless Application Protocol
 The WAP is the leading standard for information
services on wireless terminals like digital mobile
phones.
 The WAP standard is based on Internet
standards (HTML, XML and TCP/IP).

3. What is the purpose of WAP?
 To enable easy, fast delivery of relevant
information and services to mobile users.
 It consists of a WML language specification, a
WMLScript specification, and a Wireless
Telephony Application Interface (WTAI)
specification.

6. WAP Gateway
 WAP Gateway/Proxy is the entity that connects
the wireless domain with the Internet. We
should make a note that the request that is sent
from the wireless client to the WAP
Gateway/Proxy uses the Wireless Session
Protocol (WSP). In its essence, WSP is a binary
version of HTTP.

9. WML
 A markup language - the Wireless Markup
Language (WML) has been adapted to develop
optimized WAP applications. In order to save
valuable bandwidth in the wireless network,
WML can be encoded into a compact binary
format. Encoding WML is one of the tasks
performed by the WAP Gateway/Proxy.

11. WAP - WML Script
 WMLScript (Wireless Markup Language
Script) is the client-side scripting language of
WML (Wireless Markup Language). A scripting
language is similar to a programming
language, but is of lighter weight. With
WMLScript, the wireless device can do some
of the processing and computation. This
reduces the number of requests and

14. Advantage
 The advantages that WAP can offer over these other
methods are the following: open standard, vendor
