Introduction

This unit gives you an idea about what micro browsers are and why are they important for WAP
applications. In this unit you will learn some tips about how one can go about designing a
simple and well-structured design of WAP applications and what the common pitfalls are one
should avoid while designing. Lastly with an example of a WAP network you will see how
communication takes places and what are some of the uses WAP has enabled on mobile devices.

2.1 WAP Micro Browsers

To fit into a small wireless terminal, WAP uses a Micro Browser. A Micro Browser is a small
piece of software that makes minimal demands on hardware, memory and CPU. It can display
information written in a restricted mark-up language called WML.
Mobile devices use special browsing software, sometimes referred to as “microbrowsers” due
to their size and capacity, to request and display information from a network. As on the Web,
not all WAP browsers are created equal. Older devices with outdated browsers are still in
circulation, and what works on one device may not work on another at all.
