<p>This report is the written part of a bachelorthesis on the computer engineering program at</p><p>University of Halmstad. The project was a cooperate project that where done together with</p><p>Free2move Holding AB. Free2move is a company with eight employees in Sweden and four in</p><p>Malaysia. The company is today developing Bluetooth modules and RFID chips. The market for</p><p>this kind of products is growing very rapidly, last year it grew 71 percent. The most important</p><p>market for Free2move is to provide other developers with Bluetooth modules.</p><p>Free2move has recieved some inquiries from previous customers about a system that would allow</p><p>communication between two or more persons. After recieving this, Free2move started to evaluate</p><p>the grounds for such a protocol and also how the transmisison time slots should be distributed</p><p>among the parties. The result was planned to manage an infinite number of users and the possibility</p><p>for two users to talk simultaneously.</p><p>The goal of the project was to develop a prototype of a reciever with functionality according to a</p><p>specification and protocol developed by Free2move. One part of the project where to do a research</p><p>of the market to find suitable hardware for the reciever, at least a tranciever/reciever and a processor</p><p>with DA-converter. Factors such as pricing, power cousumption and size should be take in</p><p>consideration during the researchphase.</p><p>Free2move had explicity said that they where intrested in a microprocessor from Texas that had low</p><p>power comsumption and that we should concider takingthat one. The PIC microprocessor from</p><p>Micrichip was one of the other candidates. Since the specification of the protocol demanded a DAconverter</p><p>with 16 bit resouliton an external codec was neccesary to be implemented in to the</p><p>construction.</p><p>During the project negotiations about the structure and functionality of the protocol where still not</p><p>finished. This resulted in a turn in what the goal of this project was, and a new goal where set. The</p><p>goal where now to develop and construct a reciever and a transmitter and make a research of how</p><p>well diffrent kind of protocol would perform.</p>
