Indoor optical free space networks - reflectivity of light on building materials

Abstract

Over the past decade rapid development happened in the field of communication technologies based on optical fibers. Over the past decade rapid development happened in the field of communication technologies based on an optical fibers. These technologies become dominant in the field of the last mile networks as well (WDM-PON, GePON, EPON, etc.). As an alternative to the last mile networks can be considered the socalled free space optical networks (FSO). Currently, diffusion systems make an interesting concept into the future. They use secondary sources - building materials inside the room. Therefore it is necessary to pay attention to an issue of the light reflectivity on building materials.
