郑州市二七商圈4G电力无线专网建设方案研究

Research on Development Scheme of 4G Power Wireless Private Network in Zhengzhou Erqi Commercial Circle

随着郑州市二七商圈的不断发展,存在通信光缆敷设困难导致部分电力业务终端只能借助公网进行通信的问题。文章根据郑州市通信网、通信通道现状和专网业务终端接入带宽需求,通过对230 MHz与1.8 GHz频段的对比分析,提出了基于1.8 GHz频段的TD-LTE4G电力无线专网解决方案,介绍了整体系统架构和终端接入方案。通过系统仿真结果,验证了方案的可行性和有效性。

With the continuous development of Zhengzhou Erqi commercial circle, there is a problem that some power terminals can only use the public network to communicate because of the diffi culty in laying the communication cable. According to the status quo of communication network and communication channel in Zhengzhou, and the demand of access bandwidth of private network service terminals, through the comparison between 230 MHz and 1.8 GHz, a solution of TD-LTE 4G power wireless network based on 1.8 GHz is proposed, the system architecture and the access scheme of terminals are described. Through the result of system simulation, the feasibility and effectiveness of the scheme are verified.
