Appendix A. Wireless Application Protocol (WAP)

Introduction

The Wireless Application Protocol (WAP) is a set of protocols that allows the development of
applications and services for use with mobile phones and other mobile devices. The WAP Forum
maintains these protocols and their related standards and specifications.
The WAP Forum consists of a number of high-tech companies from the information technology,
software, and telecommunication industries. The objectives of the WAP Forum are to:
Bring Internet content and advanced data applications to digital mobile phones
Create a global wireless protocol specification that works across different wireless network
technologies
Enable the creation of content and applications that scale across a wide range of bearer
networks and device types
Embrace existing standards and technology wherever possible

WAP Architecture

WAP and Internet architecture

In order to apply as much leverage to the existing Internet standard as possible, the WAP stack closely
follows the Internet model. This is illustrated in Figure 1A.

This layered architecture allows applications to use the features of the WAP stack through well-
defined interfaces. This close link to the Internet architecture allows developers to use their existing
knowledge and expertise when developing applications for mobile terminals.
