Bandwidth hungry services are developing rapidly in horne networking and needs for Gigabit Horne Networks will appear shortly, following the introduction of Gigabit optical access networks. In addition, ubiquitous wireless connectivity is required by users to connect multiple multimedia devices inside the horne. Some wireless standards, such as Ultra Wide Band (UWB), are able to provide Gbitls data rate but with a limited coverage. In order to extend this coverage, we propose a multi point to multipoint (MP2MP) radio over fibre (RoF) architecture based on a NxN optical splitter. The UWB MAC layer is able to control the system and no optical MAC layer is required, so that the optical path becomes a "transparent tunnel".Simulations and experimental investigations demonstrate the technical feasibility of this innovative MP2MP RoF architecture.
