The walkie-talkie is a wireless communication tool like the mobile phone, but compared with the mobile phone, the walkie-talkie can not only communicate 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 also buy walkie-talkies for self-driving tours, hiking, mountain climbing and other recreational activities. There are more occasions to use, and there are more and more types of walkie-talkies. Generally speaking, there are 8 categories:

1. 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, but only two knobs to control the number of channels, power and volume.

2. 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, with a talking distance between 800 meters and 8 kilometers. Compared with professional walkie-talkies, commercial walkie-talkies are lighter in appearance and can be connected to earphones. They are mostly used in restaurants, shopping malls and other occasions.

3. 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, suitable for individual users.

Note: PMR 446MHz 0.5W walkie talkie for EU market.

4. Amateur walkie-talkie

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

5. Explosion-proof walkie-talkie

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.

6. Railway walkie-talkie

Railway walkie-talkies refer to walkie-talkies designed for the work requirements of the railway sector. The transmission 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 compands will be used to make the voice quality clearer.

7.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 choosing a walkie-talkie, the user should pay attention to the transmission frequency range of the walkie-talkie to be 400-420MHz or 450-470MHz to avoid unnecessary trouble.

8. Vehicle Radio

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