Can the mobile phone signal jammer interfere with the base station’s signal?

Cell phone jammers are familiar to everyone, but everyone who has taken a large-scale exam has seen them and put them at the entrance of the exam room. This is not a malicious blocking signal. On the contrary, this is to maintain fairness and provide a fair environment for candidates. However, most of the time, some people doubt whether it will affect the signal radiation of the base station, so that there is no signal in an area.

With the progress of society and the development of high technology, people’s standards are getting higher and higher. Nowadays, mobile phones have become a habit of adults and children. For elementary and middle school students, it is more important to influence what they say. Playing with mobile phones for a long time may affect their eyesight, and more seriously, neglect their studies.

Since the advent of cell phone signal jammer, they have been trusted by examination rooms, schools, prisons and other units. In fact, mobile phone signal jammers are no longer a new thing abroad, and have begun to be sold in the domestic market in recent years. The cell phone signal blocker only interferes with lower cell phone signals, so it will not affect mobile base stations and other electronic devices. Now many elementary and middle school students are holding mobile phones one by one, some are addicted to games, some are addicted to novels, etc. It is even more dangerous for school exams. Baidu has all the answers. If everyone used their mobile phones to plagiarize during the exam, it would violate the purpose and significance of the exam!

In the face of mobile phone signal shielding, we should treat it rationally and scientifically. The working principle of the mobile phone signal blocker is to send out a specific signal to wake up, block 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, and the mobile phone will send and receive text messages. Unable to recognize the original text message.

In fact, signal jammers generally do not affect the signal of the base station, so there is no need to worry, and no one will consider interfering with other people’s signals.

The mobile phone jammer scans from the low end of the forward channel to the high end at a certain speed during the working process. This scanning speed can cause garbled interference in the message signal received by the mobile phone, causing the mobile phone to fail to detect the normal microwave signal data sent from the base station. In a certain range, the mobile phone cannot be connected to the base station, and the mobile phone appears as a search network, no signal, no service system, etc., and thus cannot be used. The purpose of disabling the mobile phone is achieved. Its operating frequency is: 869~94MHz; 825~ 960MHz; 1805~1880MHz and 1900~l990MHz, etc. The operating frequency bands are CDMA800, GSM900, DCS1800, PCS1900. When the mobile phone leaves the range of the jammer, it can be fully restored to normal use. The electrical signal emitted by the mobile phone jammer is undoubtedly an electromagnetic signal, but this kind of jammer will never have any equipment to communicate with it, and it will never form a sudden change signal. In other words, this signal will always be in a relatively static state. , It will not interfere with other electrical equipment, and it is harmless to the human body.
