Abstract In the upcoming years (expected 2020), 5G technology is going to deploy all around the world. Presently a lot of researches and project on the fifth generation mobile communication system are finalized and tested successfully in the research labs. Within two to three years, 5G technology is going to replace the present technology and many mobile gadgets are coming with 5G support. The main focus of this technology is to provide better spectrum utilization, ultra speed communication, QoS, etc. In this article, the comprehensive analysis of next-generation mobile communication system is provided and it includes technologies employed for 5G. This work will give a detailed investigation and discussion on the features of 5G technology.
