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。

Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor.

The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones.
