Abstract

一种有源分布式天线系统及其中继端机，中继端机包括至少两个接入单元、第一合路器以及光单元；与第一合路器对应数量的第一射频开关、第二射频开关、第二功分器；第二合路器、第一功分器；每个第一合路器一端与至少一个接入单元相连接，另一端与第一射频开关的动端相连接；第二合路器一端分别与各第一射频开关的第一不动端相连接，另一端与第一功分器相连接；第一功分器另一端分别与各第二射频开关的第一不动端相连接；每个第二射频开关的第二不动端与相应的第一射频开关的第二不动端相连接，动端与一个第二功分器相连接；每个第二功分器的另一端与至少一个光单元相连接。本发明中继端机兼容SISO模式和MIMO模式，网络建设成本低。

Description

有源分布式天线系统及其中继端机 技术领域
本发明涉及移动通信领域，特别是涉及一种有源分布式天线系统中继端机、有源分布式天线系统。
背景技术
随着移动通信的网络建设和客户应用需求的快速发展，室内信号的覆盖需求和质量要求日益旺盛，有源室内DAS(Distributed Antenna System，分布式天线系统)逐渐成为实现室内高质量、深度覆盖的优选方案。在4G LTE(TD-LTE和FDD-LTE等LTE网络制式的统称)网络的部署过程中既存在SISO(single input single output，单输入单输出)的覆盖方案，也存在MIMO(Multi-input Multi-output，多输入多输出)的覆盖方案。部分地区先进行SISO覆盖，后续进行MIMO覆盖方案升级。但是目前DAS中继端机仅支持SISO模式或者MIMO模式其中一种，不可配置。客户在进行4G(第四代移动通信技术)网络建设时，需要根据不同的方案选用不同的DAS中继端机，如果需要由SISO升级为MIMO，只能进行设备替换，大大增加了网络建设成本。
