Wap Architecture
Abstract
WAP bridges the gap between the wireless mobile world and the internet. The Wireless Application Protocol (WAP) , is a collection of protocols and transport layers which allow mobile and portable communication devices such as mobile phones and Personal Digital Assistants (PDA’s), to receive information over the airwaves such as personal computers users obtain information over the internet. . WAP is simply a protocol- a standardized way that a mobile phone talks to a server installed in the mobile phone network.

Introduction
WAP is a hot topic that has been widely hyped in the mobile industry and outside of it. It has become imperative for all Information Technology companies in Nordic countries and beyond to have a WAP division. Many advertising agencies and "dotcoms" have announced WAP services. From the user's perspective, using WAP is
much like surfing the net on a personal computer; the mobile device is fitted with a small, or not so small, display which can be used just like a desktop browser. Information sources can be selected which are then downloaded and their content is displayed. Hyper Text links and buttons can then be pressed to move around from page to page in a very simple way. In this respect, there is very little difference between WAP browsing and desktop surfing, but, behind the scenes there are considerable differences because of the medium through which the information must travel, over radio waves rather than along hard-wired or telephone lines.

Importance of WAP
•
It provides a standardized way of linking the Internet to mobile phones, thereby linking two of the hottest industries anywhere.
•
Its founder members include the major wireless vendors of Nokia, Ericsson and Motorola, plus a newcomer Phone.com.
Compared to the wired networks there are many constraints in this wireless world. * Less band width * More latency * Less connection stability * Less predictable availability
