Choose number for walkie-talkie? Is it better to simulate?

Nowadays, more and more novice enthusiasts prefer digital walkie-talkies when they purchase machinery and equipment. Of course, they don’t even know what a digital walkie-talkie is. They will say that digital walkie-talkies are dual-purpose, and digital walkie-talkies are better than analog wireless walkie-talkies. What's the good thing?

Digital walkie-talkies have been popular for a long time, and enthusiasts often quarrel about which equipment to choose. If you are a new enthusiast, you must have already considered how to choose. This article can help you.

Analog radio and data radio

Analog radio is traditional. It has existed for decades and has made outstanding contributions to human society. It entered commercial use in 1933. Of course, it had been used in national defense for more than 20 years before that.

At that time, radio greatly improved the efficiency of information transmission, and the business process of communication equipment was developing rapidly. At that time, radio was the best communication method and all fields depended on it.

After decades of development trend of analog radio, it has already entered its shortcomings and the development trend has reached its peak. Therefore, experts have created and invented more advanced data radio systems.

There is nothing that analog radio can continue to expand, and data radio is completely different. It uses a better encoder, which can improve the sound quality to a certain level, and can also transmit data while talking. Naturally, the price is relatively expensive.

The emergence of data radio has made the field of wireless communication have a leapfrog development trend and analog comparison, mainly:

1. Larger coverage area;

2. Improve the quality of video and voice communication;

3. Various and colorful background management functions.

This kind of data-only radio is part of the many advantages relative to analog. As everyone knows, analog radio also has some distinctive benefits. For a long time, analog radio has been the main method of communication network, and it is also the only method.

Even if the existing digital technology is becoming more and more popular, most amateur radio enthusiasts are still using analog radio technology for communication. However, with the continuous development of digital technology, more and more technical professional radios have already begun to be converted into data radios. , Digital walkie-talkies provide many new functions for commercial service customers, such as data information transmission, data encryption, and one-to-one communication.

At the very beginning, mobile phones used analog radios, but I didn't know that because more and more people started to use mobile phones, communication operators had to switch to data methods, which showed greater capacity and new functions.

The key to what features you can get depends on how much money you are willing to spend, that is to say, the well-known brand and model specifications of the wireless walkie-talkies you buy. For example, DMR digital walkie-talkies can increase the battery life by at least 30% compared with analog walkie-talkies. The function is very easy to use.

When the standard analog wireless walkie-talkie is close to the edge of the data signal, it will just begin to attenuate the coefficient. At this moment, you can hear a lot of noise, even the data signal is intermittent, while the digital walkie-talkie, no matter how far you get rid of, as long as the data signal is covered Within the area, the quality of the digital signal is almost the same. Of course, if you step out of the coverage area, the data signal will quickly decline.

Most contemporary wireless walkie-talkies use FM radio broadcasting. System simulation is easier to install and operate than data. This determines that it is more cost-effective than digital walkie-talkies. However, due to the impact of data system software, simulation has become more and more serious. unwelcome.

Digital walkie-talkies transmit analog signals, and digital walkie-talkies can add many algorithms to eliminate noise, which means that the application of data radio system software will be clearer and more powerful than analog.

Advantages of analog radio

You may think that the data is very good. Simulation technology is a very long-established technology. Simulation will be eliminated immediately. Although it is being eliminated, it still has many advantages.

First of all, analog wireless walkie-talkies are easier to use. There is no need to write these complicated operations. Data requires complicated settings and logic such as time slots, color codes, groups, etc. In addition, if most of your local enthusiasts will use analog at this stage , You don’t need to add numbers.

The flaws of analog radio

There is no software development platform available for analog wireless walkie-talkies, such as ID restriction, remote killing, etc. If some people deliberately trick electromagnetic interference, it is not easy to find out who it is.

Advantages of digital walkie-talkie

Data and analog comparison have many advantages. DMR dual time slot can allow two additional calls on one frequency. ID, remark name information, GPS can be attached to data calls, digital walkie-talkies save network bandwidth, and analog relay The equipment can be modified to have data functions and clearer voice. Most digital walkie-talkies adapt to analog.

Defects of digital walkie-talkies

Although digital walkie-talkies are getting more and more popular, they still have some problems. The settings are complicated. It takes a long time for novices to understand the writing frequency. In addition, digital signals are very susceptible to frequency radiation. If a region is affected, Digital signals will get worse and worse. In addition, data machines and equipment are much more expensive than analog because they use vocoders that have to pay a patent annual fee.

The difference between data and simulation

The big difference is how they transmit radio signals. Digital walkie-talkies convert analog signals into digital format to transmit sounds, which is a string of 0s and 1. Analog radios use currents of similar sound wave frequencies to transmit sounds to the signal receiver.

The digital walkie talkie is more power-saving, which means it can work for a longer time, the longer the analog signal is separated, the worse the data signal, which means that at the coverage edge, the data signal will become more and more completely unrecognizable, digital walkie talkie The quality is not easy to change significantly in the coverage area.

The coverage area of the digital walkie-talkie is smaller than that of the analog, and the digital walkie-talkie can transmit data, such as short messages. Digital walkie-talkies can have GPS, which allows bosses to monitor their employees at all times. Digital walkie-talkies provide a stronger safety factor. Simulating machinery and equipment is cost-effective, cost-effective, and cost-effective.
