Abstract:4G-LTE technology has the advantages of fast target rate,wide channel spectrum and open interface,and can carry out multi-network transmission in the mobile internet environment. In this context,this paper describes the specific application of 4G-LTE technology in mobile communication engineering by analyzing the 4G-LTE communication network architecture. Practical research shows that in the aspect of mobile communication transmission rate,4G-LTE technology can improve the broadband transmission rate through carrier aggregation transmission. At the same time,it can also effectively solve the problems of the wireless optical fiber equipment in a specific node transmission too decentralized,transmission node data less and other issues,effectively improving the level of intelligent management of mobile communication engineering.
Keywords:4G-LTE technology;mobile communication;engineering intelligence
