A Multistandard and Multiservice Radio over Fiber System for Next Generation Networks

Next generation Optical Networks become a topical issue that requires much researcher's interest especially the improvement of last miles of the optical networks (access network). Radio over fiber technology fulfills with heterodyne optical networks needs since it answers to wideband applications requirements and meets high capacities networks. The association of RoF systems and futuristic optical access networks provides flexible high capacities networks. In this paper, we propose a RoF system architecture able to support muli-service (WiFi, WiMAX and mm-wave), multi-band (2.4, 5.2 and 60 GHz), multi-modulation schemas (BPSK, QPSK and 16QAM) and multi-data rates up to 5 Gbps. The selected transmission technique and service will depend on cell capacities, applications requirements and mobile user concentration. To validate the RoF system performances, we have simulated mm-wave Error Vector Magnitude (EVM) and constellation for different services.
