Why do different industry use different walkie-talkies?

The walkie-talkie distinguishes from the power, and can be basically divided into: 0. 5W civilian walkie-talkie, 2. 5W conventional walkie-talkie, 4W professional walkie-talkie. The power level will directly affect the talk distance of the walkie-talkie. 0. 5W civilian walkie-talkie


1. 0. 5W civilian walkie-talkie: The call distance specified by the manufacturer is usually 1 to 3 kilometers, but after testing, in the open area, the call distance is generally within 1.2 km, and the call distance in the urban area is generally 300-500 meters.


2. The 0.5W civilian machine is mainly suitable for small restaurants, restaurants, or family members who occasionally go out to play. The power level of the walkie-talkie, after testing, in the ordinary building, the call distance can only reach the height of about ten floors, if the actual call range is only within 1 km, it is recommended to buy 0. 5W walkie-talkie. Professional walkie-talkie above 4W


3. Professional walkie-talkies above 4W: The call distance specified by the manufacturer is usually 3 to 15 kilometers. After testing, such machines, the call distance is usually about 7 kilometers in the open area, and the call distance in the urban area is usually 3-4. Kilometers. The reason for this is that the manufacturer marks the theoretical call distance, and the actual call distance is greatly reduced due to environmental impact. According to the test of the electronic laboratory, the 0. 5W civilian walkie-talkie, the theoretical call distance on the sea is 30--40 km; 2. The 5W conventional walkie-talkie, the theoretical talk distance on the sea is 300--500 km; 4W professional walkie-talkie, at The theoretical talk distance on the sea is 800-1000 km; this is also the reason why the walkie-talkie with a theoretical talk distance of 16--22 km is bought, why is there a few hundred meters of talk distance?

4. Professional models above 4W, more applied to all construction sites, building security, logistics deployment, port operations, plant support, workshop operation, etc. This power level can be regarded as far away from the handheld model. The machine, if you say that the scope of your use is relatively large, choose a professional machine that is naturally 4W. 2.5W regular walkie talkie


5-2. The distance of the call in the urban area is generally 1. 5-2. The distance of the call is usually within the range of 1. 5 km. Kilometers.


6. 2. 5W power conventional machine, this type of machine has a higher cost performance, the function is stronger than the civilian machine, and the price is lower than the professional machine.
