After a first introduction of the requirements of a wireless transceiver, the main characteristics of ultra-low power radio will be analyzed.

在首次介绍无线收发器的要求之后，我们会首先分析超低功率无线电的主要特性。

Ambient radio waves have largely been ignored as a potential power source until recently, because the power of a broadcast radio signal rapidly decreases with distance.

直到最近环境无线电波才格外受到重视成为一种潜在的电源，这是因为广播电台的无线电信号发电随着距离的增加而锐减。

Although radio power has changed little over the decades, the power of lasers has grown exponentially.

尽管在过去的几十年里无线电功率几乎不变，但是激光的功率则呈指数增长。
