A combined wireless and optical channel for multiband orthogonal frequency division multiplexing (MB OFDM) ultra-wideband (UWB) radio transmission has been investigated both experimentally and theoretically. The channel consists of a directly modulated vertical cavity surface emitting laser (VCSEL), wireless channel, ultra-wideband (UWB) antenna, multimode optical fiber (MMF) and a p-i-n diode as a photodetector (PD). It has been shown both experimentally and theoretically the advantages of the MB OFDM transmission through MMF. The transmission distance increases in such a case up to 750 m. Numerical simulations carried out in the framework of the developed model show a good accord with the experimental data.
