How to distinguish digital intercom and analog intercom?

Introduction: Briefly analyze the difference and development trend of the two models of walkie-talkies.
1. How to distinguish digital intercom and analog intercom?
In the technical field of design level, radio interphones can be divided into analog intercoms with analog communication technology (that is, traditional radios that are commonly used by everyone) and digital interphones that use digital technology to carry out design levels.
In recent years, the market demand for digital walkie-talkies in the global arena has also been increasing, especially in government security departments. Existing walkie-talkies that directly use a digital signal processor are regarded as real digital walkie-talkies. In recent years, walkie-talkies that commonly use digital control data signals (such as walkie-talkies for cluster devices) do not belong to the category of digital walkie-talkies.
Digital walkie-talkies have many advantages, but the premise is that they can make better use of the spectrum market. Similar to cellular digital technology, digital interphones can carry more users on the same specific channel and continuously improve spectrum utilization. This is also a solution to deal with too crowded frequencies and has a long-term benefit. Compared with the same integrated analog voice system and data system, the digital radio can provide better data processing methods and page usage, so that more and more data applications can be integrated into the same two-way wireless communication. In the framework of base stations, the integration of voice and data services is more mature and simpler.
Second, the analog is premature in the era of digital interphones
Even though the development prospect of the digital walkie-talkie market is very optimistic, the analogue technical ability of the walkie-talkie technology is now particularly mature, and it will still serve the design of the walkie-talkie for a long period of time. The digital walkie-talkie cannot completely replace the analog walkie-talkie in a short period of time. ——In the on-site interview, many manufacturers harbored this concept, and this concept has also been recognized by experts.
Digital walkie-talkies are very good, but the price is relatively expensive. There is still a lot of way to go to replace the analog phones in the mainland of China or other parts of the world (except Europe and the United States). Only when the production cost of digital walkie-talkies is substantially Reduced, its technology is also understood by more and more manufacturers. When various digital walkie-talkies of different grades are received or replaced by different customer groups, all will be determined by the professional market of walkie-talkies. It is the customer's decision.
