Do you know the 8 ranges of use of walkie-talkies

Date:Jan 11, 2021

The walkie-talkie is a wireless communication tool like a mobile phone, but compared with a mobile phone, the walkie-talkie can communicate not only one-to-one, but also one-to-many, and there is no call charge during the call. In the past, walkie-talkies were mostly used in public security, military, medical and other public utilities. Later, commercial places such as hotels, security, and construction sites also began to introduce walkie-talkies as the main communication tool.


Nowadays, many ordinary users buy walkie-talkies for self-driving tours, hiking, mountain climbing and other recreational activities. There are more occasions for use, and there are more and more types of walkie-talkies. Generally speaking, there are 8 categories:



Professional walkie-talkie

    Professional walkie-talkies usually refer to walkie-talkies with a transmission power of 4-5W and a frequency range of 136-174MHz or 400-480MHz. The biggest feature of this type of walkie-talkie is that the communication distance is relatively long, which can reach 3- 8 kilometers. Professional walkie-talkies are generally used in construction sites, property management, factory workshops and other occasions. The operation is relatively simple. There are no digital buttons and only two knobs to control the number of channels, power and volume.



 Commercial walkie-talkie

    Commercial walkie-talkies refer to walkie-talkies with a transmission power of 0.5-4W and a frequency range of 400-800MHz, and the talk distance is between 800 meters and 8 kilometers. Compared with professional walkie-talkies, commercial walkie-talkies are lighter in appearance and can be connected to headphones. They are mostly used in restaurants, shopping malls and other occasions.



Civil walkie-talkie

    Civilian walkie-talkies refer to walkie-talkies with a transmission power of 0.5-1W and a frequency range of 409MHz. This type of walkie-talkie has a short talk distance, is compact, and the price is much cheaper than professional and commercial walkie-talkies, usually 300-500 yuan can be won, suitable for individual users.



 Amateur walkie talkie

    Amateur walkie-talkies refer to walkie-talkies in the frequency range of 144-146MHz and 430-440MHz. They are designed for amateur radio enthusiasts. They are small in size and easy to operate. The disadvantage is that the call distance is generally relatively small.

Explosion-proof walkie-talkie

    There are few brands of explosion-proof walkie-talkies, and the only three brands that can be found in the domestic market are MOTO, Vitex and Hoyitong. The so-called explosion-proof means that the walkie-talkie can be used in flammable and explosive environments, such as coal mines, gas companies, gas stations and other places.



Railway walkie-talkie

    Railway walkie-talkies refer to walkie-talkies designed for the work requirements of the railway sector. The transmitting power is generally 4-5W and the frequency range is 440-470MHz. Because the noise is very loud when the train is running, the audio output of the railway walkie-talkie is very demanding, and the voice will be compressed and expanded to make the call sound quality clearer.



 Police walkie-talkie

    Police walkie-talkies are special equipment for public security systems. The frequency range is 350-370MHz or 370-390MHz. No one can steal or embezzle them in any way. Therefore, when users choose walkie-talkies, they should pay attention to the transmission frequency range of the walkie-talkies to be 400-420MHz or 450-470MHz to avoid unnecessary trouble.



Mobile radio

    The working voltage of the car intercom is 12.5V, and the voltage of the car is generally 12V or 24V, so when the car intercom is to work in a car with a voltage of 24V, a transformer needs to be installed between the car and the intercom. The transmission power of the vehicle-mounted walkie-talkie is relatively large, generally 25-50W, and the signal transmission is far away, but it cannot be moved at will, and can only be used in the car.
