60 GHz intermediate frequency over fiber using a passive multipoint-to-multipoint architecture

60 GHz radio coverage is extended using a Radio over Fiber (RoF) multipoint-to-multipoint architecture. Two hops in the air are realized, transposition at Intermediate Frequency is performed for propagation over multimode fiber, and low-cost photonic components are used. This transparent RoF architecture has to allow a large optical budget for the NxN optical splitter sharing the media between the different Access Points. Finally, a real-time transmission between two commercial WirelessHD devices at 3 Gbit/s is achieved.
