Over the last three decades, interest in Infrared (IR) technology
as a medium to convey information has grown considerably. This is
reflected by the increasing number of devices such as laptops,
PDAs, and mobile phones that incorporate optical wireless
transceivers and also by the increasing number of optical wireless
links available for indoor and outdoor use. The popularity of IR is
based on the advantages it has over radio including unregulated
bandwidth, immunity to radio interference, and inherent security.
Optical Wireless Communications examines some of the most important
features of optical wireless communication systems. It considers
the benefits and limitations of IR as a medium conveying
information wirelessly and compares the advantages and
disadvantages of infrared to microwave and other radio systems. It
also details the evolution of IR communication systems and
describes atmospheric and other types of data transmission
limitations. The book presents design fundamentals of optical
concentrators, as well as a review of some of the most important
receiver optical front-ends (containing imaging or non-imaging
concentrators and optical filters), including an explanation of the
different sources of infrared noise and an introduction to eye
safety. It also describes optical wireless transmitter and receiver
design issues, typical modulation, coding, and multiple access
techniques, and introduces IrDA protocols and wireless IR
networking.
