We have projected and verified a bidirectional intra-/inter-radio-access-technology carrier-aggregation method for next-generation heterogeneous mobile network supported Filter-bank multi-carrier. Successful transmission of intra/inter-band carrier-aggregation between five broadband FBMC signal and three bands 4G-LTE-A signal over 50-km SMF plus 10-m free-space are successfully broadcasted by employing incoherent light-injection scheme in downlink. In uplink, two intra-bands carrier-aggregated WLAN IEEE 802.11g signal is carried over the equal distance. High receiver sensitivity, low EVM, clear constellation diagrams show successful delivery of different wireless services for different consumers. Therefore, proposed hybrid-system should become potential solution for future mobile-fronthaul network because of its low latency and high-capacity.
