    In this paper, we present numerous small cell base station, i.e. femtocell base station (FCBS), architectures based on the number of transceivers (e.g., single or dual transceiver) and operating frequency bands (e.g., microwave and millimeter wave bands) existing in a FCBS for serving control-plane and user-plane (C-/U-plane) traffic in indoor environments under both traditional C-/U-plane coupled architecture (CUCA) as well as prospective C- /U-plane separation architecture (CUSA). With a system level simulation of a multi-tier network, we evaluate the performances of these FCBS architectures in terms of control-plane, user-plane, and an aggregate C-/U-plane traffic capacities. The simulation results show that because of serving only U-plane traffic by a FCBS in CUSA, CUSA outperforms CUCA for a single transceiver based FCBS in terms of user-plane traffic capacity irrespective of operating frequency. However, the presence of dual bands at a dual transceiver based FCBS results in higher aggregate C-/U-plane traffic capacity than that of a single transceiver based FCBS. Finally, we discuss a number of strengths and weaknesses, viability challenges, and open issues of these FCBS architectures.
