Security/hotel wireless intercom system

From the perspective of power, walkie talkies can be basically divided into: 0.5W civilian walkie talkies, 2.5W conventional walkie talkies, and 4W professional walkie talkies. The power level will directly affect the communication distance of the walkie talkie.

0.5W civilian walkie talkie

0.5W civilian walkie talkie: The manufacturer's stated communication distance is usually 1 to 3 kilometers, but after testing, the communication distance is generally within 1.2 kilometers in open areas and 300-500 meters in urban areas.

The 0.5W civilian aircraft is mainly suitable for small restaurants, eateries, or occasional family outings. This power level walkie talkie, after testing, can only reach a communication distance of about ten floors in a regular building. If the actual communication range requirement is only within 1 kilometer, it is recommended to purchase a 0.5W walkie talkie.

Professional walkie talkies above 4W

Professional walkie talkies with a power of over 4W: The manufacturer usually indicates a communication distance of 3 to 15 kilometers. After testing, it has been found that the communication distance of these machines is usually around 7 kilometers in open areas and 3-4 kilometers in urban areas. The reason is that the manufacturer marks the theoretical communication distance, while the actual communication distance is greatly discounted due to environmental factors. According to tests conducted in the electronic laboratory, a 0.5W civilian walkie talkie has a theoretical communication distance of 30-40 kilometers on the sea surface; A 2.5W conventional walkie talkie has a theoretical communication distance of 300-500 kilometers on the sea surface; 4W professional walkie talkie, with a theoretical communication distance of 800-1000 kilometers on the sea surface; This is also the reason why a walkie talkie with a theoretical communication distance of 16-22 kilometers has a communication distance of several hundred meters when purchased.

Professional models above 4W are widely used in construction sites, building security, logistics deployment, port operations, factory support, workshop operation deployment, and so on. This power level can be considered as the machine with a long communication distance among handheld models. If you have a wide range of applications, you naturally choose a 4W professional machine.

2.5W regular walkie talkie

2.5W regular walkie talkie: The manufacturer's stated communication distance is usually 3 to 9 kilometers, but the actual communication distance is in open areas, usually within 3.5 kilometers, and in urban areas, the communication distance is generally 1.5-2 kilometers.

Conventional machines with a power of 2.5W have a high cost performance ratio, stronger functions than civilian machines, and lower prices than professional machines.

Domestic and imported walkie talkies

Although there is a significant price difference between domestically produced walkie talkies and imported walkie talkies, machines of the same power are indistinguishable in terms of communication distance. The difference between domestic walkie talkies and imported walkie talkies mainly lies in sound quality, workmanship, and stability. If used every day: After using domestic walkie talkies for a year, 80% of the machines will have various malfunctions; After 10 years of use, 80% of imported machines can still function normally. If you only use it occasionally, it is recommended to buy a domestic machine. The price is very cheap and the communication distance is similar to that of an imported machine. If you want to use it every day and the environment is very harsh, you should choose imported walkie talkies. Imported walkie talkies have good workmanship, loud sound, and good stability.
