Compared with 4 G

5 G has larger network capacity

faster peak rate and more connections.Millimeter wave can meet the needs of 5 G continuous large bandwidth frequency with its rich spectrum resources.This paper analyzes the advantages and disadvantages of millimeter wave in wireless communication

introduces the application scenario of millimeter wave in 5 G

and finally proves the feasibility of using millimeter wave to improve the system speed and capacity through the test conclusion.
