Diffuse optical wireless communications for domotic indoor networks

Abstract

In this paper, rhe use of optical wireless cornmirnication.s,for D0motic.s is analyzed in depth. This sriidv shows the capabilities and limitations uf /his technique as an alternative of RF .for home device interconnection. The success of IEEE 802. I I and Blrretoolh standardy-based devices ,for home applications can become a potential problem due to the reduced number af ,frequencies ./or channel allocarion. Infrared communication is constrained by walls and ,firrnitirre, reducing rhe size of commtrnications picocells to the room size, avoiding co-channel inteiference problem. This prototype is designed to lest ./id1 diffusc intereonnecrion withoiit pointing at commercial data rates (as usiia1l.v domestic devices do not need transmission rates over hundred uf Kbytes). For theorerical and experimental testing we have selected a hasic I Mb/s channel, hiit this haid rate can be easily increased if it is needed.for,fiirther applications.'.
