A Survey on Millimeter Wave Mobile Communications for 5G Cellular Networks

Abstract: The Present era has experienced an exponential growth in wireless mobile communication. This requires a huge bandwidth, which has motivated the utilization of millimeter wave (mm-wave) frequency spectrum to be deployed for future broadband cellular networks. Fifth generation (5G) cellular networks are being developed to satisfy the increasing data traffic among mobile devices. 5G cellular networks are expected to have much higher network capacity and provide multi-gigabits-per-second data rate for each user to support multimedia applications with stringent quality of service (QoS) requirements. Millimeter-wave communication is a promising technology for future 5G cellular networks to provide very high data rate (multi-gigabits-per second) for mobile devices. Enabling Device to Device communications over directional mm wave networks is of critical importance to efficiently use the large bandwidth to increase network capacity. Basically in the traditional wireless cellular networks devices were communicating with each other through base stations, whereas the fundamental network architecture of 5G networks has the hybrid combination of 4G and mm wave communication.
