These three characteristics make digital walkie-talkie an inevitable trend in the development of future walkie talkie technology. In the 1970s, Motorola took the lead in introducing digital technology into the walkie talkie system design. In 1975, it produced a digital voice encrypted DVP walkie-talkie. In 1980, it developed a digital data communication system. In the 1991 "Desert Storm" operation, 35,000 digital walkie-talkies are used. Obviously, with the development of radio communication technology, people's requirements for wireless communication quality and spectrum resources are increasing, and digital walkie-talkies will definitely have a huge market demand. However, no matter how widely used digital walkie-talkies are, analog technology, which is already very mature in walkie-talkie technology, will continue to provide design services for walkie-talkies for a long period of time. Development direction to meet the different needs of communication users. Digital walkie-talkies cannot replace analog walkie-talkies in a short time. These two walkie-talkies will develop together with their own characteristics.
