Radio walkie-talkies are the first wireless mobile communication equipment used by humans, and have been used as early as the 1930s. In 1936, the American Motorola Company developed the first mobile radio communication product. Subsequently, in 1940, it developed the first handheld two-way radio AM walkie-talkie weighing 2.2 kg for the US Army Signal Corps, with a communication distance of 1.6 km. In 1962, Motorola introduced the first handheld wireless walkie-talkie HT200 weighing only 935g.

After nearly a century of development, the application of walkie-talkies has become very common. It has moved from specialized fields to general consumption, and expanded from military to civilian use. It is not only a professional wireless communication tool in mobile communication, but also a consumer tool with the characteristics of consumer products that can meet the needs of people's lives. The walkie-talkie is a terminal device for point-to-multipoint communication, allowing many people to communicate with each other at the same time, but only one person can talk at the same time. Compared with other communication methods, the characteristics of this communication method are: instant communication, one-to-one response, economical and practical, low operating cost, no call costs, easy to use, and also has functions such as group call broadcast, system call, confidential call, etc. . In dealing with emergencies or dispatching and commanding, its role cannot be replaced by other communication tools. Most of the traditional walkie-talkies use simplex analog communication methods, some walkie-talkies use frequency division duplex analog communication methods, digital walkie-talkies are used more in trunking communication, but most of them are frequency division duplex methods. The market positioning of radio walkie-talkies and other wireless communication tools (such as mobile phones) is different, and it is difficult to replace each other. The radio walkie-talkie is by no means an outdated product, it will be used for a long time. With economic development and social progress, people pay more attention to their own safety, work efficiency and quality of life, and the demand for radio walkie-talkies will also increase. The mass use of walkie-talkies by the public has promoted radio walkie-talkies to become a communication tool that people love and rely on.
