The multipath dispersion in a non-directed line-of-sight (LOS) indoor optical wireless communications (OWC) channel limits the transmission bandwidth. In this study, we improve the transmission bandwidth by employing a TEM_{00} mode laser beam and an alignment-free light shaping diffuser (LSD). We derive a new expression for the radiation field distribution of the diffused Gaussian beam (DGB) and...
Achieving high data-rates in optical wireless involves theoretical limits and practical constraints. In this paper we discuss these, with reference to two system examples. A 1.25 Gigabit/s demonstrator that has been fabricated as part of the European Community Framework 7 project OMEGA is described, and a 280Mbit/s demonstrator that is currently under development as part of the same project. In each...
Indoor Gigabit optical wireless communication systems have the potential to offer multiple high-speed data services that can be delivered to homes via an optical fibre cable in the near future. In this paper we will discuss the challenges involved in the design of such systems and future possible advances. Results from a recent cellular Gigabit prototype link will also be presented and discussed.
