5G millimeter wave (mmWave) communications

5G communication system is attracting researches attention throughout the world for providing seamless user experience in 5G network which can accommodate large number of users in Internet of Things (IoT) environment with a gigabit-per-second (Gbps) data rate in mmWave communications with the consideration of Big-Data (BD). In 5G environment several billions of user devices will be connected seamlessly among each other in mmWave communications along with secure connections. 5G Millimeter Wave (mmWave) communications system proposes mmWave signal transmission along with low latency connection which will offer gigabit-per-second (Gbps) speed. This paper discusses 5G applications and services along with 5G vision and challenges. There are many challenges with the proposed mmWave communications system. 5G mmWave communications system will be revolutionizing for the users.
