Driven by the booming amount of wireless devices, novel ways need to be found to combat radio spectrum congestion and interference between the devices in order to maintain an adequate quality of communication. In a building, radio-over-fibre techniques enable to create wireless pico-cells, which provide high capacity to the users, operate at reduced always-on power levels, and diminish the interference levels. Moreover, connections between devices in different pico-cells can be realized via the fibre backbone network. Using the Optical Frequency Multiplying technique, radio signals can be generated and transported with high capacity and with low dispersion penalties in both multimode and single-mode fibre networks. By using multiple wavelength channels, different pico-cell interconnection patterns can be established simultaneously via these fibre backbone networks. The patterns can be reconfigured by means of wavelength conversion and wavelength-routing in a centralized radio-over-fibre optical crossconnect, while not affecting the radio signal format. Such techniques can enlarge the application of wireless ad-hoc communication, by creating a flexible extension of the reach of the ad-hoc wireless links.
