无线通信系统的一个主要特征即是使用高频(无线电)信号来传递消息。无线的方法最能发挥高频电路的使用。虽然各种无线通信系统在所传递消息的方法、办公方法以及设备系统构成等方面有很大差异,但设备中生成、接收和查看高频信号的底层电路大都是相同的。

(A key feature of wireless communication systems is the use of high frequency (radio) signals to communicate messages. The wireless method makes the most of the use of high-frequency circuits. Although various wireless communication systems differ greatly in the method of message transmission, office method, and equipment system configuration, the underlying circuits in the equipment to generate, receive and view high-frequency signals are mostly the same.)
