本申请实施例的能量发射设备200和无源电子设备100：
1、是国内业界首个真正意义上解决了长达几十年通信行业里一直困扰的方案；在安全发射功率下、一部分通过热能消耗散发浪费掉的，将有效的转化为微能源收集存储利用起来，达到了既能通信，又能传输电能的双重利好。
2、完全可兼容实践突破解决了射频通信发射端的室内应用和0-3米以内的有效性。比方说，家庭路由器在小型房间内就可以给小型的电子设备实现无线供电和可持续永久续航。
3.各项技术要求完全符合国家无线电管理委员会及国际通用标准组织的规范，可以很好的兼容以往设备和未来的标准延续性，做到通用通配。

获取预设频点的、发射功率随时间和空间中至少一个参数适应性变化的激励信号；向天线模块提供该激励信号，以使天线模块向外传输无线信号或者微能量或者微能源。
可以理解的是，该预设频段可以但不限于为433MHz、915MHz，2.4GHz。可以理解的是，发射功率随时间和空间中至少一个参数适应性变化，以使得该发射功率可以在0dB-27dB动态调节转换。例如，在允许的公共频率点433MHz、915MHz，2.4GHz等三种频段下，分别将发射功率随着时间和空间的变化，自适应动态调节0dB-27dB转换，以达到所规定的有效距离内的微能量输出。
可以理解的是，本申请实施例的无线传输方法或者多频段射频能量动态无线传输方法可以应用于上述任一实施例的能量发射设备200、通信系统10。当然，该方法也可以应用于其他能实现该方案的模块、装置、存储介质、电子设备中，本申请实施例对此不进行限定。
可以理解的是，本申请实施例的无线传输方法或者多频段射频能量动态无线传输方法，可以通过发射模块210、控制模块220、调节模块230和天线模块240的相互配合实现获取预设频点的、发射功率随时间和空间中至少一个参数适应性变化的激励信号；向天线模块提供该激励信号，以使天线模块向外传输无线信号或者微能量或者微能源的方案。其具体的实现方式可以参见前述能量发射设备200的实施例，在此不再进行详述。
