摘要:

室内覆盖是5G网络部署中的重点和难点。通过分析5G大规模天线系统的技术特点以及对室内覆盖的性能提升,提出室外宏基站仍是室内浅层覆盖的重要解决手段,并根据外场测试结果对理论分析进行佐证。同时根据覆盖需求使用有源室分和小基站等手段,构建完整的室分解决方案。

关键词: 5G, 室内覆盖, 大规模天线, 有源室分

Abstract:

Indoor coverage is a very important and difficult problem for 5G network deployment.By analyzing the technical characteristics of 5G massive MIMO systems and solutions to improve the performance of indoor coverage.The most important way which the outdoor macro cells were still for basic coverage was proposed,proved by theoretical analysis based on the field test results.By the meantime using digital indoor distribution system and small cells according to scenarios requirement can provide an all-round solution for indoor coverage.

Key words: 5G, indoor coverage, massive MIMO, digital indoor distribution
