What is a two way radio? June 2,2023.

    Two way radio is a wireless motor consisting of a transmitter and a receiver. Like a mobile phone, it can talk to distant objects through it. Because the complex terminal of the same channel can receive signals at the same time, it is widely used in the construction site where one-to-many communication is needed. Maybe some people think that since they are talking on the phone, they can use the mobile phone; But there are other advantages, such as instantaneous operation without the need to enter a phone number, which simplifies the communication process and improves efficiency. 

    In addition, except for some models, two way radios can also communicate outside the cell phone's service area. It can be used even in desolate mountains, where radio waves cannot reach, or in areas where lines are congested during disasters, and it is not necessary to pay for mobile phones because it does not use telephone lines. The key points of two way radio purchase will first explain one by one the key points of two way radio purchase. The types of two way radios can be divided into several types. The communication distance and license requirements vary. You are advised to make a preliminary selection based on the purpose of use. Low power type: License free, suitable for general simple use

    Amateur low power two way radios have an effective radiated power of less than 1W. They can be used without a license and are usually relatively affordable and easy to use. However, its communication distance is short, up to 500 meters, and when it is used in the house, it may cause unstable communication through the wall, so it is only recommended for simple situations such as ordinary activities. Amateur model: can be used in large-scale activities

    The transmitting power of this kind of two way radio is about 5W at most, and the distance can reach about 5km, which is much more than the low-power radio mentioned above. It can be used in a wide range of stable communication, so it is very convenient to use both indoors and outdoors. On the other hand, such products usually have larger body sizes and consume power faster, and they also require a license to use. 

    Network radio: Just like a mobile phone, it is not limited by distance

If you don't want to be limited by the distance of communication, the network radio may be a good choice, as long as the phone service area, anywhere. 

    Moreover, the machines, which use lines from various telecoms companies, are generally cheap, have relatively long battery life, and are light and do not require a license, making them easy for anyone to use. However, when the phone is outside the service area, it cannot be used due to lack of signal. If the line is clogged due to disasters, it will be affected as well as mobile phones. And like 3G radios, when the company stopped the service will also be unable to use, compared with the other two types, do not rely on the strength of the signal advantage, so some people think it is better to use mobile phones.
