摘要
为达到利用现有4G高铁覆盖站址快速实现5G 2.6 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8TR RRU与2TR RRU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。
In order to achieve the goal of using the existing 4G high-speed railway coverage sites to quickly realize 5G 2.6 GHz band high-speed railway coverage,referring to the test results of 5G trial network,through theoretical estimation,compare the coverage,capacity and cost of the two coverage methods using 8TR RRU and 2TR RRU.Through comprehensive comparison,it is concluded that 8TR RRU has no advantage over 2TR RRU,which can be used as a reference for technical selection of 5G high-speed railway 2.6 GHz band coverage projects.
