What is a cell phone signal jammer and how does it work?
Cases of exam fraud have occurred over the years, and it has become a problem that the education sector pays more and more attention to. With the development of technology, more and more people use mobile phones to cheat. In order to ensure the information security of the examination room, some ordinary colleges and universities generally use Cell phone signal jammers to interfere with external signals within a certain range. Today, I will talk to you about how mobile phone jammers interfere with mobile phone signals.
What is a cell phone signal blocker?
A mobile jammer is an electronic communication device that can interfere with the signal between a mobile phone and a base station. It is often used in special places where mobile phones are disabled, such as examination rooms, confidential laboratories and other special places.
How do cell phone jammers work?
Its working principle is to implement co-frequency electromagnetic interference on the wireless network on which mobile phone communication depends, so that the mobile network cannot communicate normally, so as to achieve the purpose of interference. The cell phone signal blocker only blocks cell phone signals and will not affect other electronic devices.
In addition, it is also necessary to ensure that the signal field strength of the jammer is stronger than or even much larger than the field strength of the mobile signal in the interference area. Therefore, if the signal strength of the interference area is relatively large, we will recommend customers to purchase high-power cell jammers. In particular, the closer the interference location is to the base station, the stronger the BCH field strength, the smaller the effective blocking area, and the worse the interference effect. (This is also one of the reasons why many customers report that the actual jamming distance of the jammer may not reach the jamming distance described on the website).
yhdefense is a comprehensive high-tech enterprise integrating R&D, production, sales and interference solutions. The company is mainly committed to the R&D and production of signal shielding equipment. In this field, it has successively developed and produced 100+ mobile phone signal shielding equipment and 500+ signal jamming solutions. Praise and affirmation, some series of products have been widely used and supported in prison system, military and various examinations.
