Solution of common antenna of 4G/5G in 5G Era by Yongchang YU, Dian ZHANG, Mingling DING

“…During the 4G construction period, there were problems such as lack of antenna coverage resources at the base station site, and difficulty in coordination with residential property management.In 5G era, it is difficult to add poles at existing sites.Therefore, it is urgent to propose a solution of common antenna of 4G/5G, and to deploy quickly.The solution of 4G/5G common antenna was discussed, and a suitable solution for China Telecom’s single pole network construction was proposed.It can reduce the cost of the tower renting and network operation.At the same time, it can prove the convenience and efficiency of 5G network deployment.…”

4G/5G low-cost wireless coverage scheme based on tapping the potential of existing networks by Dan YANG, Jing ZHANG, Peijin LV, Yun LU, Zhanchun YANG

“…Relevant research data shows that, the cost of China's 5G network deployment is expected to be about three times that of 4G.The network architecture, key technical principles and source hardware characteristics of the existing 4G and 5G networks were analyzed and studied.Three ideas for tapping the potential were proposed, which are using that how to use the old 4G resources in the construction of 5G networks, releasing 4G resources through 5G network deployment and maximizing use of 4G/5G sources, thereby reducing the investment cost and upgrade difficulty of the network.…”
