The WAP specifications remain 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. The WAP is an open, worldwide specification that
empowers mobile users with wireless devices to easily access and interact with information and
services instantly.

Task Analyze what type of devices will use WAP? Explain with examples.
The core purpose of WAP is to enable easy fast delivery of relevant information and services to
mobile users. Handheld digital wireless devices such as mobile phones, pagers, two-way radios,
smart phones, and communicators can use WAP.
WAP was created after largely unsuccessful efforts of several companies to arrive separately at
a viable technology delivery format. These companies included Nokia, Motorola, and Phone.com.
The problem for network operators was the selection of a wireless data infrastructure supported
by the many different mobile handset makers. No such infrastructure existed at the time.
The wireless industry came up with the idea of WAP. The point of this standard was to show
internet contents on wireless clients, like mobile phones.
 WAP stands for Wireless Application Protocol

 WAP is an application communication protocol
 WAP is used to access services and information
 WAP is inherited from Internet standards
 WAP is for handheld devices such as mobile phones

 WAP is a protocol designed for micro browsers
 WAP enables the creating of web applications for mobile devices.
 WAP uses the mark-up language WML (not HTML)
 WML is defined as an XML 1.0 application

Did u know? Which wireless networks does WAP work with?
WAP is designed to work with most wireless networks, such as CDPD, CDMA, GSM, PDC,
PHS, TDMA, FLEX, ReFLEX, iDEN, TETRA, DECT, DataTAC, Mobitex and GPRS.
The Wireless Application Protocol is targeted to offer the following:

 A global wireless service specification to be adopted by appropriate standards bodies
which would be independent of the network infrastructure system in place.
 An advanced service and Internet content to digital cellular phones and terminals.

 A common standard means with the potential for realizing economies of scale, encouraging
cellular phone manufacturers to invest in developing compatible products, and cellular
network carriers to develop new differentiated service offerings as a way of attracting
new subscribers.
