系统侧耦合模块、第二滤波模块、第二变频模块、第二放大模块、模数转换模块和接口。
系统侧设备把从BBU接收的下行数字信号进行数模转换、放大、滤波，变频为中频信号f1(低于100MHz)，通过电力线传递给终端侧设备。
同时，把终端侧传递过来的上行模拟信号f2进行滤波、变频、放大和数模变换，通过接口把上行模拟信号传递给BBU。
参照图5所示，对应上述应用于终端侧设备的信号的传输方法，本发明还提供了一种终端侧设备，包括：
终端侧耦合模块400，配置为接收电力线传输的系统侧设备发送的下行模拟信号；
终端侧处理模块500，配置为将下行模拟信号转换为长期演进LTE信号或4G信号支持频率的下行无线信号；
通讯模块600，配置为将下行无线信号发送出去。
其中，通讯模块600包括双工器和天线。
为了实现将下行模拟信号转换为LTE信号或4G信号支持频率的下行无线信号，终端侧处理模块500包括：
第三滤波模块，配置为对下行模拟信号进行滤波处理，得到第七信号；
第三变频模块，配置为对第七信号进行变频处理，得到频率LTE信号或4G信号使用频率的第八信号；
第三放大模块，配置为对第八信号进行放大处理，得到下行无线信号。
终端侧设备还配置为接收移动终端发送的上行移动信号，并将上行移 动信号转变为上行模拟信号发耦合至电力线内。
为了实现这个目的，通讯模块600，还配置为接收移动终端发送的上行移动信号；
终端侧处理模块500，还配置为将上行移动信号转换为上行模拟信号；
终端侧耦合模块400，还配置为将上行模拟信号耦合到电力线上进行传输。
为了实现将上行移动信号转换为上行模拟信号，终端侧处理模块500还包括：
第四滤波模块，配置为将上行移动信号进行滤波，得到第九信号；
第四变频模块，配置为对第九信号进行变频处理，得到频率低于第二预设频率值的第十信号；
第四放大模块，对第十信号进行放大处理，得到上行模拟信号。
其中，第二预设频率值为100MHz。
终端侧设备把系统侧设备传递的下行模拟信号变频为运营商运营的4G信号或LTE信号频率的信号，然后通过天线发射出去，完成下行覆盖。
同时接收手机等移动终端发出的上行移动信号，将上行移动信号变频到中频，通过电力线发送给系统侧设备。
参照图6所示，终端侧设备的硬件架构，主要包括上行通路和下行通路两部分。
下行通路，将系统侧设备耦合至电力线中的无线信号发射出去，下行通路包括：终端侧耦合模块、第三滤波模块、第三变频模块、第三放大模块、双工器和天线。
上行通路，将移动终端发送的上行移动信号变频后耦合到电力线中传输，上行通路包括天线、双工器、第四滤波模块、第四变频模块和第四放大模块。
终端侧设备把系统侧设备通过电力线传输的下行模拟信号滤波，去除干扰，变频为运营商实际4G信号或LTE信号频率的信号，然后经过放大后，通过天线发射出去，完成下行覆盖；
终端侧设备同时把接收的移动终端发送的上行移动信号滤波，变频为中频信号，放大后，通过电力线发送给系统侧设备。
参照图7所示，以1800MHz的LTE信号为例，来详细介绍本发明的终端侧设备和系统侧设备通过电力线的传输过程中LTE信号的频率变化。
系统侧设备首先把1800MHz的LTE信号变频到50MHz，在电力线中传输，完成第一次变频；
终端侧设备再把50MHz的LTE信号变频为1800MHz，完成第二次变频。和1800MHz信号直接在电力线传输相比，双变频技术可以使覆盖距离增大300％以上。
参照图8和图9所示，传统电力线传输设备都是采用TDD制式，即信号发射和接收使用相同的频率，采用时分模式共享带宽。
本发明中，系统侧设备和终端侧设备传输采用FDD制式，信号发射和接收使用不同的频率，和TDD制式相比，FDD制式的理论系统容量增加一倍。
系统侧设备把4G信号或LTE信号引入建筑物内部的电力线，信号经电力线传输到建筑物内部的每一个角落。对于需要信号覆盖的地方直接在电力线插座上插一个终端设备即可，方便快捷，无需布线，运营商设备投资小。终端设备为家庭级，体积小，价格便宜，是否使用决定权在用户手里，不存在居民担心电磁辐射反对问题。
