    In this paper, a multi-band, namely co-channel microwave and 60 GHz millimeter-wave bands, enabled femtocell base station (FCBS) architecture (MBFA) is proposed to address non-uniform and asymmetric traffic in 5G cellular mobile networks. All femtocells are deployed in a multi-storage building. For the co-channel microwave band, the interference between FCBSs and the macrocell base station is avoided using almost blank subframe based enhanced inter-cell interference coordination techniques. The coexistence of both bands architecture is studied, and the outperformance of millimeter-wave over co-channel microwave bands is shown in terms of system capacity and spectral efficiency. We analyze the use of MBFA to address non-uniform traffic and asymmetric traffic from splitting uplink/downlink as well as control-plane/user-plane. Finally, the outperformance of MBFA over the single band enabled FCBS architecture in terms of energy efficiency, system capacity, and spectral efficiency is shown.
