Abstract
In this paper we demonstrate a novel multiservice wired/wireless integrated access architecture of cloud radio access network CRAN based on radiooverfiber passive optical network RoFPON system which utilizes scalable multiple frequency millimeterwave MFMMW generation based on tunable optical frequency comb TOFC In the baseband unit BBU pool the generated optical comb lines are modulated into wired RoF and WiFi/WiMAX signals respectively The multifrequency RoF signals are generated by beating the optical comb line pairs in the small cell The WiFi/WiMAX signals are demodulated after passing through the band pass filter BPF and band stop filter BSF respectively whereas the wired signal can be received directly The feasibility and scalability of the proposed multiservice wired/wireless integrated CRAN are confirmed by the simulations
