Mobiledating
Abstract
The purpose of the project has been to investigate which method of wireless communication is more
suitable for a mobile dating application. How two units can find each other in a limited area and
uphold communication channels and finally, to verify whether it is possible or not by building a
prototype.
A number of requirements were established for the application: Range is at least 20m, application
must be autonomous, developed in a widely supported programming language, free communication
must be supported. The three compared methods were IrDA, “Internet alternatives”, and Bluetooth.
Of the listed requirements, IrDA supported 4/5, Internet supported 3/5 and Bluetooth supported
almost 5/5.
After examining the results from the investigation, we chose Bluetooth to be used in the
development of the prototype. The prototype was developed both as server and client (peer-to-peer)
since it has to be independent. This lead to that additional time was consumed because of lack of
experience in the project group. Bluetooth turned out to be a slow technology, it took a long time to
find other units and the transfer from “Sun Wireless Toolkit Emulator” to a real life mobile phone
did not work completely.
