5G低成本建设方案研究

Research on 5G Low-cost Construction Schemes

900 MHz网络的大规模建设,给运营商带来了极大的成本压力,低成本建设成为运营商的迫切需求。首先对5G站点的成本组成进行分析,得出影响建设成本的主要因素为主设备价格,影响维护成本的主要因素为租金、电费,通过分场景设备选型及900 MHz室分等方式达到降低主设备投资的目的,通过直供电改造、天馈整合、落实免租免电政策等方案降低租金、电费等维护成本,同时分析了低成本方案可能对网络覆盖、网络质量及网络容量等方面造成的影响。

The large-scale construction of 900 MHz network brings great cost pressure to operators,and low-cost construction becomes an urgent need for operators.It first analyzes the cost components of 5G base stations,and concludes that the main factors affecting the construction cost are the price of the main equipment of the base station,and the main factors affecting the maintenance cost are rent and electricity.Secondly,the purpose of reducing the investment in the main equipment is achieved through the selection of equipment in different scenarios and 900 MHz indoor distribution system.Through direct power supply renovation,antenna feed integration,the implementation of free rent and free electricity policy and other means,the maintenance costs such as rent and electricity bills are reduced.At the same time,the impact of these low-cost means on network coverage,network quality and network capacity is analyzed.
