Diffuse optical wireless communications for domotic indoor networks

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.'.
