Model for indoor wireless optical link

Abstract

In the last few years, there has been a growing interest in optical wireless communications for indoor and outdoor applications. Infrared technology is the best option for indoor environments due to it is immune to radio interferences, the spectrum is freely available and infrared components are inexpensive, small and consume little power. This thesis deals with the structure of indoor optical wireless communications and with their possible applications. Optical transmitters, optical receivers and lenses are the basic elements of optical links and their characteristics and parameters are described. The beam in an indoor optical wireless link reflects on walls and various objects. This thesis presents a power budget of the link and includes the reflectivity of the surfaces where the beam is reflected
