In terms of design technology, radio walkie-talkies can be divided into analog walkie-talkies designed with analog communication technology (also known as traditional walkie-talkies) and digital walkie-talkies designed with digital technology. What is the difference between digital walkie-talkie and analog walkie-talkie?
Retevis analog walkie talkie
The traditional analog walkie-talkie is a communication mode in which voice, signaling, and signals are modulated to the transmission frequency of the walkie-talkie in a continuous wave mode, and optimized processing such as amplification. It has the advantages of mature technology, complete system, and relatively low cost.

Digital walkie-talkies are designed using digital technology to digitize the voice signal, using a specific digital encoding method and a specific baseband modulation form, and using a digital signal processor to optimize the data communication mode, which means that the digital two-way radio transmission frequency All modulations are digital. Digital walkie-talkies can make better use of spectrum resources, improve voice quality, improve and improve voice and data integration, change the weakness of control signals that decrease with the increase in communication distance, and provide better data processing and interface functions.
Compared with traditional analog walkie-talkies, digital walkie-talkies have significant advantages such as strong voice anti-interference ability, high confidentiality, narrower channel bandwidth, and stronger data transmission capabilities.
1. Clear voice quality and better confidentiality are required.
2. Not only requires a complete scheduling function, but also a complete data transmission function.
3. There is a long-term plan and sufficient budget funds.
The difference between analog walkie-talkie and digital walkie-talkie is actually like the previous analog TV and digital TV. With the development of radio communication technology, people’s requirements for wireless communication quality and the increasing frequency of spectrum resources, digital walkie-talkies will have a huge Demand market. 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 services for the design of walkie-talkies for a long period of time. It will be small, low-cost, powerful, and more commercialized. 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 respective characteristics.
At present, DMR has matured in the global market. More and more companies, especially security-related companies, such as security departments, security companies, etc., choose digital walkie-talkies, not only because of the good confidentiality of digital walkie-talkies, but also because of the uniqueness of digital walkie-talkies. Trunking function, GPS function, more convenient management, with the economic development, the market for digital walkie-talkies will become broader and more application scenarios
