以下为对上述各实施例的示例性介绍。
作为一种示例，下行指令信号先于CW信号发送。
时序一：设备在初始入网时或在结束上行传输之后需要将与天线连接的开关预置至接收机以便接收未来的下行指令信号，如图2A或2B所示，第一开关1016预置至定向耦合模块的输入端1a。充能储能模块1013的第二开关1017预置至定向耦合模块的耦合端口2a，以保证指令信号到来时，系统能快速激活工作。
时序二：当设备收到下行指令后，开始向网络发送对应的响应或者进行相应的上行操作时，当设备发送信号1时，与天线连接的第一开关1016切至1c，使CW节点提供的CW信号被反射回网络。当设备发送信号0时，与天线连接的第一开关1016切至1b与此同时充能储能电路的第二开关1017切换至2b，使CW节点提供的CW信号被电路吸收用于充能。
时序三：当上行通信结束时，将与天线连接的第一开关1016复位至定向耦合模块的输入端1a，充能储能模块1013的第二开关1017复位至定向耦合模块1015的耦合端口2a。
作为另一种示例，CW信号先于下行指令信号发送。
时序一：设备在初始入网时或在结束上行传输之后需要将与天线连接的第一开关1016预置至充能储能模块1013以便CW信号到来时开始充能使系统快速激活，如图2A或2B所示，第一开关1016预置至匹配网络的输入接口1b，充能储能电路的第二开关1017预置至匹配网络的输出端口2b。
时序二：设备激活后，将与天线连接的第一开关1016切至定向耦合,模块1015的输入端1a，充能储能模块的第二开关1017切至定向耦合模块的耦合端口2a，等待接收下行指令。当设备收到下行指令后，开始向网络发送对应的响应或者进行相应的上行操作时，当设备发送信号1时，与天线连接的第一开关1016切至1c，使CW节点提供的CW信号被反射回网络。当设备发送信号0时，与天线连接的第 一开关1016切至1b，与此同时充能储能模块1013的第二开关1017切换至2b，使CW节点提供的CW信号被电路吸收用于充能。
时序三：当上行通信结束时，将与天线连接的第一开关1016复位至匹配网络的输入接口1b，充能储能模块的第二开关1017复位至匹配网络的输出端口2b。
在上述各个示例中，指令信号与CW信号可以工作于同一载频点Fc，此时匹配网络1018可内置于充能储能模块中。指令信号与CW信号也可以工作于不同的频点Fc1和Fc2，此时匹配网络10181和10182分别匹配于Fc1和Fc2。
