In this paper, the authors analyzed that the Millimeter wave Mobile Broadband (MMB) system for 5G mobile communication provides higher bandwidth. The propagation characteristics of the millimeter wave has been simulated and analyzed. Through system simulations it is shown that the basic MMB system employing Multiple Input and Multiple Output-Orthogonal Frequency Division Multiple access (MIMO-OFDM) is capable of delivering an average cell throughput and cell-edge throughput performances which are 10-100 times better than the current 20MHz LTE-Advanced (LTE-A) systems.
