摘要

通过对POI的结构定向设计

对FDD制式的信号区分上下行

对TDD制式的信号不再区分上下行

并采用高性能的物理器件对干扰信号进行抑制

最大限度的抑制和规避不同系统间的干扰

实现双缆方式建设TDLTE MIMO双流。已建成的隧道内4G专网覆盖指标均满足预期

实现了TD-LTE MIMO双流良好覆盖。

Abstract

In order to suppress or avoid the interference of different systems and make the TD-LTE dual stream realized

the structure of POI was designed directionally. In the structure of POI

the uplink and downlink of FDD were designed separately and the TDD were on the contrary. In the test on tunnel scene built by this POI

all the indicators meet our expectations and a good coverage of TD-LTE MIMO Dual was realized.
