The phenomenal global demand for wireless communication links with greater bandwidths is motivating engineers world over to come up with alternatives communication links. One of such system that has received a great deal of attention and has shown evidence of a promising future is infrared optical communications.This project explores the fundamental aspects involved in designing and building a transmitter and a receiver as part of an infrared optical wireless link for indoor use. It is mainly concerned with extracting as much bandwidth as possible from the circuit designed. The system built in this project is capable of data transmission of over 20Mbits/second but this is however nowhere near the limit of the systems as will be discussed in the dissertation. Optical communication links have been developed which are capable of data transfer rates of 1.25Gbits/second (Jeganthan, 2001).The work done in this project and that which have been done by others present a compelling argument as to why infrared optical wireless communications is a formidable form of wireless communications and as a matter of fact a worthy alternative to the well known radio frequency (RF) systems
