Many customers want to know “How far radio can walkie talkie reaches?”In fact, the question is hardly answered because many factors affect communication range, and communication environment and the technical specifications are main factors

Communication Environment

The communication environment determines the communication distance of the walkie-talkie, so the exact communication distance cannot be accurately determined. Environmental factors mainly include paths, density of trees, environmental electromagnetic interference, buildings, weather conditions, and terrain differences. These factors and other parameters directly affect the field strength and coverage of the signal.

When used in cities, obstacles are the most important factor affecting the signal propagation distance of the walkie-talkie. Electromagnetic interference and noise will also affect the actual communication distance of the walkie-talkie. For example, a professional walkie-talkie with a power of 5 watts, the actual talking distance in the city is generally only 2 to 5 kilometers and a 10Watt power walkie talkie, in open area, may can reach to 8kms

In high ground, many buildings or relatively sealed rooms, the communication distance will be shorter. However, when supported by the system base station, the talk range of the walkie-talkie can reach ten kilometers or even dozens of kilometers.

Maritime communication is an ideal communication environment for walkie-talkies on the earth. There are generally no obstacles and minimal interference, but in fact, handheld walkie-talkies at sea can only pass about 10-20 nautical miles. Also, if the antenna is higher, the talk distance of the walkie-talkie will be farther.

Technical Specifications 

Such as the walkie talkie output power, receiving sensitivity, the gain of the antenna and whether the antenna is damaged, these will have a certain impact on the communication distance. The higher the power, the farther distance of the communication range, Chierda walkie talkie 10W output power can reach much farther than low power walkie talkie.

Whether the user uses it correctly will also affect the maximum communication distance of the walkie-talkie to a certain extent. For example, if the battery power is low, the communication quality will deteriorate and the talking distance will reduce. So when the walkie talkie gives low battery warning, then please fully charged the battery before use. And also the walkie talkie must be installed with matched antenna. If the antenna impedance does not match, will seriously affect the communication distance. For the user, pay attention to tightening the antenna when changing to the antenna. In addition, it is not allowed to use an antenna that is not provided by Chierda or an antenna that does not conform to the frequency of the walkie talkie.

So if you want to buy suitable walkie talkie for your purpose, please contact us, we are professional in recommending suitable models for you.
