Abstract
The huge demand for wireless data transmission is never met. Many generation of mobile communication systems have been stepped over and some of the main challenges that need to be address are yet unsolved. Increasing demand for large area coverage, over one Trillion of mobile user equipments (UEs) capacity, high data rate, low latency, high quality of service and low energy consumption are the target for the future technology. This paper presents overview of previous wireless technologies and today wireless communication network. And due to exponential increase in the demand of present UEs there is needed to move beyond 4G as the theoretical 4G specifications have been reached. The paper addressed challenges that will be encountered by future wireless communication, proposed techniques and the promising imaginations of the future 5G for 2020 and beyond.
