Today, communication has increasing influence on our daily life. Wireless data communication services allow people to access the data network without a physical connection.
IEEE 802.11 is being proposed to provide wireless connection for local area network
(LAN) using spread spectrum techniques in the Industrial, Scientific, Medical (ISM) bands
and baseband infrared techniques. In this project, we want to design and build a real
wireless LAN system operating at 902-928 MHz of the ISM bands. The physical layer of
this network has been designed to perform direct sequence spread spectrum processing and
RF transceiving. A variable data transmission strategy is employed in this system so that
we are able to configure the physical layer dynamically based on the medium access control
(MAC) layer’s control frame.
