摘要
5G时代,绝大部分的应用将发生在室内场景,室内覆盖将是5G深度覆盖和容量吸收的重要手段,而5G信号穿透墙体更加困难,室内将更加依赖室分覆盖。目前绝大部分普通楼宇、隧道等场景的覆盖普遍选择成本较低、速率和容量受限的传统无源室分,为了提升无源室分的速率和容量,针对5G分布式MIMO做了深入的研究和应用,对推动5G低成本无源室分的建设有着重要意义。
In 5G era,most of applications occurs in indoor scenario,the indoor coverage is an important means for deep coverage and enrolling capacity.It is difficult for 5G signal to penetrate walls,so indoor signal is more dependent on indoor distributed antenna system.Now most of common building,tunnels scenarios usually select low-cost,limited throughput and capacity traditional passive indoor distributed antenna system(DAS).In order to improve its throughput and capacity,it launches in-depth research and implement for 5G distributed MIMO,which is of great significance to promote 5G low-cost DAS construction.
