Abstract:In this letter the use of hybrid WiMedia-defined Ultra-Wideband (UWB) and IEEE 802.16d WiMAX radio-over-fibre is proposed and experimentally demonstrated for multimode based in-building optical networks with the advantage of great immunity to optical transmission impairments. In the proposed approach, spectral coexistence of both signals must be achieved with negligible mutual interference. The experimental study performed addressed an indoor configuration with 50 μm multi-mode fibres (MMF) and 850 nm Vertical-Cavity Surface-Emitting Lasers (VCSEL) transmitters. The results indicate that the impact of the wireless convergence in radio-over-multi-mode fibre (RoMMF) is significant for UWB transmissions mainly due to MMF dispersion and electrooptical (EO) devices with limited bandwidth. On the other hand, a WiMAX transmission is feasible for a 300 m MMF and 30 m wireless link in presence of UWB, with -31 dBm WiMAX EVM.

Abstract-Radio over Fiber (RoF) system has attracted much industry and research interest to extend the wireless cell coverage and reduce the cost by using the distributed remote antenna units (RAUs). However, the effective transmission fiber length in the RoF systems would be limited due to the time division duplex (TDD) mode used in the practical WiMAX access. Here, we study the transmission limitations and performances of the standard WiMAX signal for RoF systems. The throughputs and packet-losses at different fiber lengths are also investigated and analyzed. Besides, in order to increase the emitting power of the RAUs, a robust TDD switching mechanism is proposed in each RAU for RoF system.

“…Nevertheless, OFDM-UWB and QAM-WiMAX modulation formats require higher linearity on the radio over fiber (RoF) distribution system [16] than less complex modulations, such as on-off keying (OOK) modulation. UWB and WiMAX coexistence on low-cost multi-mode fiber (MMF) was reported in [17] for indoor applications. In this case, a single wavelength signal without any polarization multiplexing technique was employed.…”

Abstract-In this paper, the feasibility of the joint distribution of ultra-wideband (UWB) and WIMAX wireless using polarization multiplexing as a coexistence technique is proposed and experimentally demonstrated within the framework of passive optical networks (PON). Four single-and orthogonal-polarization multiplexing schemes are studied targeting to reduce the mutual interference when UWB and WiMAX are distributed jointly through standard single-mode fiber (SSMF) without transmission impairments compensation techniques and amplification. Experimental results indicate successful transmission up to 25 km, in SSMF exceeding the range in typical PON deployments. The radio link penalty introduced by optical transmission is also investigated in this paper.Index Terms-Integrated optical-wireless access, optical fiber communication, polarization division multiplexing, radio-overfiber, ultra-wideband radio, WiMAX radio.
