The signal – transmission distance of a walkie – talkie is affected by various factors, such as transmission power, environmental conditions, and antenna performance. The following is a detailed introduction:
- Hand – held Walkie – talkies6
- 0.5W – 1W: A 0.5W walkie – talkie can reach a communication distance of about 1.5 kilometers in an ideal state, that is, without any obstacles and electromagnetic interference. In an urban environment, the actual communication distance is usually between 200 meters and 800 meters. A 1W walkie – talkie performs slightly better, with a communication distance of 500 meters to 1 kilometer in the urban area and 1 to 2 kilometers in open areas.
- 2W – 3W: In the urban environment, the communication distance is generally 1 to 3 kilometers. In open areas, it can be extended to 3 to 5 kilometers.
- 4W – 5W: In the urban environment, the communication distance can reach 2 to 5 kilometers. In open suburban or field environments, the communication distance can reach 8 to 10 kilometers.
- Vehicle – mounted Walkie – talkies1
- Usually, the power of vehicle – mounted walkie – talkies is between 25W and 50W. In the urban environment, the communication distance can reach 5 to 15 kilometers, and in open areas, it can reach 10 to 25 kilometers.
- Repeater Stations5
- The power of fixed repeater stations is generally within 100W, and most of them are used at a lower power (approximately within 20W). The communication distance is related to the height of the installed antenna. The higher the antenna is installed, the farther the communication distance is. Under compliant conditions, it can reach 30 kilometers, and when used in conjunction with an IP network, it can even reach 100 kilometers or more.
- Marine Walkie – talkies4
- Since marine walkie – talkies are mostly used at sea with almost no obstacles, the communication distance is generally more than 10 kilometers, or even farther.
- Public – network Walkie – talkies
- The transmission power of public – network walkie – talkies is ≤0.5W. When the operator’s network coverage is sufficient, they can achieve national – wide communication.
