Abstract [en]

Mobile positioning combined with an application with restaurants and other businesses pinpointed on a map, have been identified as a killer application for Wireless Application Protocol (WAP), services. CitiKey today has a mobile city guide with maps, restaurant information, hotel information and a lot more information about events and service. The goal of CitiKey is to provide these services on all mobile digital devices. Currently CitiKey is available on Windows CE and Palm OS based platforms, and as a WAP service.

In conjunction with the WAP service a GSM mobile positioning system would make CitiKey’s WAP service a killer application. In the future positioning could also be added to the CE and Palm devices, but then they would need additional hardware, which for now, is undesirable.

There is a wide range of companies manufacturing positioning systems, and there are an equal number of approaches of how to determine a position of a cellular phone.

This report examines some of these systems, but are in particular investigates Ericsson’s Mobile Positioning Service (MPS), because this system is standardized by ETSI (European Telecommunication Standards Institute), and is very flexible, which means that the programming interface can be used even for the other systems. Furthermore this system is going to be deployed in the very near future.

This report examines different techniques of determining the position of a cellular phone, and takes a look at their accuracies now and in the future.

I have also integrated the positioning system into CitiKey WAP services. And in the process I have created some new services such as: “What’s nearby?” and “Where am I?”

In the report I will briefly discuss some security and “big brother”/privacy issues. At the end here are some thought about future applications, and exciting features which I haven’t had time to examine further.
