This report is the written part of a bachelorthesis on the computer engineering program atUniversity of Halmstad. The project was a cooperate project that where done together withFree2move Holding AB. Free2move is a company with eight employees in Sweden and four inMalaysia. The company is today developing Bluetooth modules and RFID chips. The market forthis kind of products is growing very rapidly, last year it grew 71 percent. The most importantmarket for Free2move is to provide other developers with Bluetooth modules.Free2move has recieved some inquiries from previous customers about a system that would allowcommunication between two or more persons. After recieving this, Free2move started to evaluatethe grounds for such a protocol and also how the transmisison time slots should be distributedamong the parties. The result was planned to manage an infinite number of users and the possibilityfor two users to talk simultaneously.The goal of the project was to develop a prototype of a reciever with functionality according to aspecification and protocol developed by Free2move. One part of the project where to do a researchof the market to find suitable hardware for the reciever, at least a tranciever/reciever and a processorwith DA-converter. Factors such as pricing, power cousumption and size should be take inconsideration during the researchphase.Free2move had explicity said that they where intrested in a microprocessor from Texas that had lowpower comsumption and that we should concider takingthat one. The PIC microprocessor fromMicrichip was one of the other candidates. Since the specification of the protocol demanded a DAconverterwith 16 bit resouliton an external codec was neccesary to be implemented in to theconstruction.During the project negotiations about the structure and functionality of the protocol where still notfinished. This resulted in a turn in what the goal of this project was, and a new goal where set. Thegoal where now to develop and construct a reciever and a transmitter and make a research of howwell diffrent kind of protocol would perform.
