This article introduces signal jammers and radio waves. What is a radio wave? Many people don’t know. Radio waves are electromagnetic waves that propagate in space. Radio waves of various frequencies are used in all parts of our lives. Mobile phones can receive signals through radio waves, which have multiple deterrent effects on the frequency of radio waves used in phones, and have different functions.
A smartphone that can be connected to the Internet is connected to a mobile phone base station (base station) through radio waves, and transmits voice, characters, and images to the other party through a communication line, which is convenient for supporting life. Communication is possible within a radius of several kilometers. This is a kind of signal interference, which emits radio waves essential for wireless communication. However, there are also many problems, some people speak loudly in the car. Someone walks while typing a text message. In this case, I want to cut off the telephone signal, I want to make the signal out of range, and signal interference equipment has appeared.
We used signal jammer on the train to block the radio waves. The radio waves disappeared in a blink of an eye and went out of range. The problem is public traffic congestion. Therefore, it is important to use the jammer correctly. Using a mobile phone is a problem. In some places, a device that blocks the radio waves of mobile phones can be placed. It was launched after an unscrupulous customer disgusted. The device emits interfering radio waves. It may emit enough radio waves to interfere with the call. The signal condition is poor, and the phone cannot make or receive calls.
