4G signal network disruptor
The reasons that affect the 4G network signal are as follows:
1. If there are multiple wireless devices in the wireless environment, there will be channel conflicts, and the problem of network signal crosstalk will have an impact;
2. Strong signal interference sources such as radio transmission towers, electric welding machines, trams or high-voltage power transformers within 100 meters of wireless equipment and cable lines will also cause strong interference to network signals or equipment; signal jammer
3. The signal is actually transmitted outdoors, and the weather conditions have a great impact on the wireless signal. If it is in a thunderstorm or when the weather is gloomy, the signal attenuation will be more severe, and the signal can be transmitted farther in a sunny day;
4. The space is crowded and the space is not open enough. The wall in the room is the main obstacle. Because the wireless local area network uses the wireless microwave frequency band. The biggest feature of microwave is that it propagates almost in a straight line, and the diffraction ability is very weak. Therefore, the wireless receiving device behind the obstacle will receive a very weak signal, or no signal.
