WAP Service Developer's Guide for Nokia Series 40Version 1.0Copyright © 2002. Nokia Corporation. All rights reserved. 41 INTRODUCTIONThis WAP Service Developer's Guide provides information and practical examples fordevelopers who want to optimise their existing WAP services for the Series 40 phones. Series40 is a UI category for Nokia 128 x128 pixel screen resolution. It comprises a passive matrixcolour screen with two soft keys. The current Nokia handsets that belong to this category areintroduced in Chapter 3. This document highlights the possibilities, limitations, andrequirements of service development, and provides a good introduction to the Nokia style ofdesigning user interfaces.The Wireless Application Protocol (WAP) enhances the functionality of mobile handsetsthrough real-time interactive services. The protocol has been designed especially for smallscreens and low bandwidths, and it offers a wide variety of wireless services over theInternet for handsets. It was also designed to allow content to be delivered over any bearerservice, even when delivery of the services is enabled over GPRS, 3G or any other type ofnetwork. WAP over GPRS opens up new possibilities for application development, and thereare also some optimizations in GPRS, that can be done by service developers.Chapter 2 describes some general usability issues concerning WAP service development.Chapter 3 introduces the browser user interfaces elements, keys, display and browsingconventions. Chapter 4 outlines some general WML elements, which are mandatory featureson WAP 1.2.1, according to WAP Forum specifications. Chapter 5 introduces some optionalWAP 1.2.1 features that are supported in most of the WAP1.2.1 compliant phones.This guide is not written for service developers only, but essentially for anyoneinvolved in creating the wireless information society and who needs to know moreabout service creation on small mobile terminals. It can be used in conjunction withthe Nokia Mobile Internet Toolkit.The Nokia Mobile Internet Toolkit offers developers an environment for creating,testing, and demonstrating WAP applications. This allows service providers toevaluate the usability of wireless applications and services together with their end-user organization. In this guide, we have collected a lot of what we have learned tohelp developers improve their services. We believe that good usability will increaseuse and satisfaction, and thus increase revenues for service providers.This guide does not purport to describe WAP in detail, and it is not meant to replaceany WAP specification.1.1 ReferencesUser's guide for Nokia 7210WAP Characteristics list can be found at http://www.forum.nokia.com/The Nokia Mobile Internet Toolkit can be downloaded fromhttp://www.forum.nokia.com/GPRS related documentation could be found at http://www.forum.nokia.com/
