5G evolution and need: A study

Due to exponential increase in wireless access bandwidth that is commercially available to the end user, the 4^th generation wireless technologies have been deployed in many countries. Even 4G systems cannot effectively address issues such as spectrum crisis and high energy consumption due to an explosion of wireless mobile devices and services. In order to address these issues, 5G research is being made on development of World Wide Wireless Web (WWWW), Dynamic Adhoc Wireless Networks (DAWN) and Real Wireless World and is expected to be deployed by 2020. In this paper, we have discussed some aspects of 5G communication some challenges and requirements.
