Abstract
Bandwidth hungry services are developing rapidly in home networking and needs for gigabit home 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 home. Some wireless standards, such as ultra wideband (UWB), are able to provide Gbps data rate but with a limited coverage. To extend the coverage of this system to the scale of the house, some possible architectures are presented. Among them, we focus on a multipoint-to-multipoint (MP2MP) radio-over-fibre (RoF) architecture based on a N × N optical splitter that is very promising. 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.
