无线通信英语:Wireless communication)是指多个节点间不经由导体或缆线传播进行的远距离传输通信, 利用收音机、无线电等都可以进行无线通信。

无线通信包括各种固定式、移动式和便携式应用,例如双向无线电、手机、个人数码助理及无线网络。其他无线电无线通信的例子还有GPS、车库门遥控器、无线鼠标等。

大部份无线通信技术会用到无线电,包括距离只到数公尺的Wi-fi,也包括和航海家1号通信、距离超过数百万公里的深空网络。但有些无线通信的技术不使用无线电,而是使用其他的电磁波无线技术,例如光、磁场、电场等。

Radio 无线通讯

Radio communication.  Information such as sound is converted by a transducer such as a microphone to an electrical signal, which modulates a radio wave sent from a transmitter. A receiver intercepts the radio wave and extracts the information-bearing electronic signal, which is converted back using another transducer such as a speaker.
An audio signal (top) may be carried by an AM or FM radio wave.

Radio is the use of radio waves to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
