Unit 1: Understanding WAP (Wireless Application Protocol)

 A varied choice for consumers in advanced mobile communication applications and Notes
services.

 An advanced services and Internet content to digital cellular phones and terminals.
Consumer benefit through more and varied choice in advanced mobile communication
applications and services.

 Offer operators, infrastructure and terminal manufacturers, and content developers a
common environment that will enable development of value-added service for mobile
phones.
All the applications of the protocol will be scalable with a variety of bearer transport. The WAP
protocol 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).
It consists of a WML language specification, a WML Script specification, and a Wireless Telephony
Application Interface (WTAI) specification. WAP is published by the WAP Forum, founded in
1997 by Ericsson, Motorola, Nokia, and Unwired Planet. Forum members now represent over
90% of the global handset market, as well as leading infrastructure providers, software developers
and other organizations.

The WAP specifications continue to be developed by contributing members, who, through
interoperability testing, have brought WAP into the limelight of the mobile data marketplace
with fully functional WAP–enabled devices (see Figure 1.1).

Based on the Internet model, the wireless device contains a micro browser, while content and
applications are hosted on Web servers.

1.1.3 Objectives of WAP

WAP considers the consumer viewpoint: of not only they enjoy the benefits of the Web but also
using it to pass time during, say, commuting. The concept is very lucid: someone with a cell
phone, pager, or PDA should be able to do limited Web surfing.
