Products Detail
Products call distance
The call distance of the handheld phone can reach 6 kilometers in a flat and open barrier-free environment, but because the transmission of radio waves will be affected by obstacles (such as buildings and trees); likewise, some external factors often weaken the call signal, and the call range will also change. When there is network support, the call distance of the walkie-talkie can reach tens of kilometers. The factors that affect the call distance and effect of the walkie-talkie include the following aspects:
1. System parameters:
The stronger the transmitter output power, the greater the coverage of the transmitted signal.
The higher the reception sensitivity of the communication machine, the farther the communication distance will be.
The gain of the antenna, when the antenna is matched with the machine, usually, the antenna height is increased, and the receiving or transmitting ability is enhanced. The antenna used in handheld walkie-talkies is generally a spiral antenna, which has a smaller bandwidth and gain than other types of antennas and is more susceptible to human influence.
2. Environmental factors:
Environmental factors mainly include path, tree density, environmental electromagnetic interference, buildings, weather conditions, and topographic differences. These factors and other parameters directly affect the field strength and coverage of the signal.
3. Other influencing factors:
The battery is low. When the battery is low, the call quality will deteriorate. In severe cases, there will be noise, which will affect normal calls.
Antenna matching.
The quality of the sound mainly depends on the pre-emphasis and de-emphasis circuit, as well as the more advanced speech processing circuit "the application of speech diffuser circuit and low-level expansion circuit", which has a good effect on fidelity speech.
The factors that affect the distance and effectiveness of walkie-talkie calls are also related to the season, with summer being better than winter.
