Abstract [sv]

The purpose of this project was to design and evaluate prototypes for wireless speech transmission on the unlicensed ISM band. It will be a one-way communication, where a transmitter will be able to broadcast speech to many receivers. The project is performed by order of Free2move, which is a company that design wireless communication products. Free2move has given specification for the project. The prototypes are supposed to be as small as possible, maximum power consumption of 40 mA and the sound will have telephone quality. The project included hardware design and software design. To begin with, a block scheme was made to identify the different parts in the system. Various components was compared and evaluated such as radio-chip, microcontroller (MCU) and amplifiers. During the design of the prototype cards, a coupling scheme was drawn up and after that it was routed in a layout program. The software design consisted of programming the microcontroller which controls the RF- Transceiver. The project resulted in two working prototypes, a transmitter and a receiver together with belonging software.
