5G Technology Evolutions

5G technology has number of existing generations of wireless technologies in terms of their portal, efficiency, effectiveness, and cost-benefit analysis. The paper puts a focus on the evolution and development of various generations of mobile wireless technology along with their significance and advantages of one over the other. From past several decades, mobile wireless technologies have experience 4 or 5 generations of technology revolution and evolution, namely from 1G to 4G. The Current research in mobile wireless technology concentrates on promoting the implementation of LTE technology and 5G technology. At present, the term is not officially used. In 5G, the research on the development of World Wide Wireless internet access (WWW), Dynamic adhoc Wireless Networks (DAWN) and Real Wireless World. In this paper, we focusa new network architecture for the next-generation of mobile networks, 5G. In this architecture, the mobile device will have the ability to get to the Radio Access Technology - RAT based on certain user-defined criteria.
