why not buy some running jammers for signal

With the progress of society and the development of high technology, people’s level is getting higher and higher. Now mobile phones have generally become a living habit of adults and children, and the impact is even more important for elementary and middle school students. Playing mobile phones for a long time is very important. We must take a rational and scientific approach to the cell phone jammer. It may affect eyesight, and even more serious is the waste of schoolwork.In fact, the signal jammer generally does not affect the signal of the base station, so don't worry, no one will want to interfere with the signal of others.

The working principle of the mobile phone signal jammer is to send out a specific signal to awaken or interfere with the signal between the mobile phone and the base station, so that the mobile phone has no signal or cannot find the network service. The text message sent and received by the mobile phone will also become garbled Therefore, the original message cannot be recognized.Call quality is first and most closely related to the call environment. In complex structures such as buildings, aisles, basements, etc., these locations are usually severely blocked by communication signals.

The strength of signal reception is mainly related to the distance from the base station.At the same time, the density of nearby buildings and floors will also affect the signal transmission. The tighter the building layout, the worse the signal reception may be. The closer the distance, the stronger the signal. If the signal encounters a wall, it will be weakened. If the room is just opposite to the base station, and there are many walls or obstructions on the side towards the base station, this situation will happen even on the same floor.
