Unit 1: Understanding WAP (Wireless Application Protocol)

WAP bridges the gap between the mobile world and the Internet as well as corporate intranets Notes
and offers the ability to deliver an unlimited range of mobile value-added services to
subscribers—independent of their network, bearer, and terminal. Mobile subscribers can access
the same wealth of information from a pocket-sized device as they can from the desktop.

1.1.2 History of WAP

WAP is a global standard and is not controlled by any single company. Ericsson, Nokia, Motorola,
and Unwired Planet founded the WAP Forum in the summer of 1997 with the initial purpose of
defining an industry-wide specification for developing applications over wireless
communications networks. The WAP specifications define a set of protocols in application,
session, transaction, security, and transport layers, which enable operators, manufacturers, and
applications providers to meet the challenges in advanced wireless service differentiation and
fast/flexible service creation. There are now over one hundred members representing terminal
and infrastructure manufacturers, operators, carriers, service providers, software houses, content
providers, and companies developing services and applications for mobile devices.

Did u know? What is the purpose of WAP?

To enable easy fast delivery of relevant information and services to mobile users.
Present Day Scenario

All players in the vertical benefit form the common development format:
 Handset manufacturers
 Access providers
 Network infrastructure

 Content providers
 Mobile consumers
Carriers will be able to develop gateways that work with a variety of phones and all applications
and content. Handset manufacturers can develop high volume, low cost handsets for all carriers.

The WAP specifications formulate a group of protocols in application, session, transaction, security,
and transport layers, which aid operators, manufacturers, and application providers to cope with
the challenges in advanced wireless service differentiation and fast/flexible service creation.
There are now over one hundred members representing terminal manufacturers, infrastructure
providers, operator carriers, service providers, software houses, content providers and companies
developing services and applications for mobile devices.
WAP also defines a Wireless Application Environment (WAE) aimed at enabling operators,
manufacturers, and content developers to develop advanced differentiating services and
applications including a micro browser, scripting facilities, e-mail, World Wide Web (WWW)–
to-mobile-handset messaging, and mobile-to-telefax access. WAP also formulates a wireless
application environment (WAE) aimed at activating operators, manufacturers, and content
developers to develop advanced differentiating services and applications including.
 Micro browser
 Scripting facilities

 E-mail
