摘要

为达到利用现有4G高铁覆盖站址快速实现5G2.6 GHz频段高铁覆盖的目的

参考5G试验网测试结果

通过理论估算

对比使用8TRRRU与2TRRRU两种覆盖方式在覆盖、容量和造价3个方面的差异

经综合对比得出8TR RRU较2TR RRU并无优势

供高铁5G 2.6 GHz频段覆盖工程项目技术选型参考。

Abstract

In order to achieve the goal of using the existing 4 G high-speed railway coverage sites to quickly realize 5 G 2.6 GHz band high-speed railway coverage

referring to the test results of 5 G trial network

through theoretical estimation

compare the coverage

capacity and cost of the two coverage methods using 8 TR RRU and 2 TR RRU. Through comprehensive comparison

it is concluded that 8 TR RRU has no advantage over 2 TR RRU

which can be used as a reference for technical selection of 5 G high-speed railway 2.6 GHz band coverage projects.
