Free space optics - extension to fiber-networks for the "last mile"

Optical wireless is an excellent nomadic broadband solution (high bandwidth) for connecting the backbone to the users (last-mile-access). This technology must be seen as supplement to conventional radio links and fiber optics. At the moment our main work in this field is to increase the reliability and availability. In that case we are evaluating wireless hybrid (optical microwave) links at our department. First results show a availability of 99.9991% of such a hybrid system.
