What's the longest talking distance of walkie-talkie?
Take the distance between walkie-talkie and car radio as an example. The transmitting power of 7W is 2-4 kilometers in the urban area and 4-7 kilometers in the open space. 5 W /4 W transmission power, urban area 1-3 km, open area 3-5 km.
From here, we can see that the distance of walkie-talkie is influenced by some factors, but for ordinary walkie-talkies, the distance of walkie-talkie will be around 10 km.
Influencing factors of walkie-talkie distance
The walkie-talkie is realized by radio wave transmission in the communication process, and the radio wave transmission will be affected by some obstacles, thus affecting the transmission effect and transmission distance of radio waves, just as the telephone may be affected by bad signals during the call, which will reduce the call quality, so the communication distance of the walkie-talkie using radio wave transmission will be affected by some factors.
There are three factors that affect the communication distance of walkie-talkie, namely the system parameters of walkie-talkie, the influence of environment and other factors.
As for the factors affecting the system parameters of walkie-talkie, the walkie-talkie can use antenna gain to ensure long communication distance. As for the influencing factors of environmental factors, they are mainly influenced by the path. Density of trees, weather conditions and electromagnetic interference, etc. As far as other influencing factors are concerned, such as wireless matching and insufficient power, they can all affect the communication distance of walkie-talkies.
