The popularity of user demand for data services and intelligent terminal

resulting in 4G network in capacity

speed

load spectrum and etc. can not meet people’s demand on the network. Therefore

5G network along with the tide of history the oncoming. Begins with a review of the development history of mobile communication in recent years

summed up in line with the application of 5G network structure

including wireless access cloud

intelligent open cloud control

high efficiency and low cost of forwarding cloud three domains

the modified architecture has large capacity

high rate

low latency advantage; second again mechanism on the basis of discussing 5G of four potential technology: coverage enhancement technique

frequency effect lifting technology

spread spectrum technology and energy efficiency promotion technology

at last

summarize the advantages of 5G technology are described

and future research challenges.
