Architectural Shift from 4G to 5G Wireless Mobile Networks?

Due to the ever increasing user demand for higher data rate and seamless communication through their mobile devices the current wireless mobile networks need to be upgraded to support such high requirements. The current fourth generation wireless mobile network (4G) based on All-IP Network architecture provides high data rates, low latency and low-cost implementation. But there are few specific user applications that require very high data rate and uninterrupted access to the internet. A sophisticated modern mobile technology termed the fifth generation wireless mobile network (5G) is proposed for the future. 5G will make use of Flat-IP Network architecture which will not only provide very high data rates but also provides increased spectrum efficiency, average cell throughput and supports ubiquitous computing. In this paper we discuss this evolution of wireless mobile network technology specifically the shift in the architecture from 4G to 5G to achieve a full real wireless world.
