Abstract: Beginning with the introduction of WiMAX, this paper studies the 4G broadband wireless work (BWAN),
the international standard of roaming or nomadic users with connection to access service, and the latest 4G wireless
communication technology. At last, it conducts that munication protocols to cut down IP lookup mechanism and the crucial
technical mechanisms to solve the fast switching in 4G work..
