4 (26)1. INTRODUCTIONThis Service Developer's Guide for the Nokia 9110i Communicator provides information and practicalexamples for developers who want to develop WAP services for Nokia 9110i. 9110i Communicator is anadvanced communications device with a feature-rich WAP services application. The document willhighlight the possibilities, limitations and requirements of service development and provides a goodintroduction to the Nokia style of designing user interfaces.The Wireless Application Protocol (WAP) will enhance the functionality of mobile handsets throughreal-time interactive services. The protocol has been designed specially for small screens and lowbandwidth, and it offers a wide variety of wireless services over the Internet using handsets. However,in 9110i especially the WAP services screen size differ a lot from common handsets and should betaken into account when designing services that are both fast and easy to use, and offer the usermaximum enjoyability. In addition to 9110i-specific issues, many of the instructions in this documentcan be used to maximize interoperability and ease of use on various other browsers.This guide is not written for service developers only, but essentially for anyone involved in creating thewireless information society and who needs to know more about service creation on small mobileterminals. It can be used in conjunction with the Nokia WAP Toolkit.The Toolkit offers developers an environment for creating, testing and demonstrating WAP applications.This allows service providers to evaluate the usability of wireless applications and services togetherwith their end-user organization.We at Nokia are very proud of our user interfaces and we have spent a lot of effort in constantlyimproving them. In this guide we have collected a lot of what we have learned to help developersimprove their services. We believe that good usability will increase use and satisfaction andsubsequently revenues for service providers.This guide is not intended to be a detailed WAP document and it is not meant to replace any WAPspecification.1.1 ReferencesUser's guide for the Nokia 9110The Nokia WAP Toolkit can be downloaded from http://www.forum.nokia.com/Wireless Application Specifications http://www.wapforum.org/Information about Nokia products can be obtained from http://www.nokia.com/1.2 Contact informationDeveloper support can be obtained through Forum Nokia web-page http://www.forum.nokia.com/
