Apart from being an effective tool in the fight against exam cheating, these devices can also protect people from various security threats and criminal activities. The device adds an extra layer of security for domestic and foreign delegates; proves helpful for silence in lectures and seminars; prevents detainees from being connected to the outside world; and many of these events. A cell phone jamming circuit or cell phone jamming circuit is an instrument or device that prevents a cell phone from receiving a signal. Basically, a mobile phone jammer circuit is an RF transmitter that broadcasts a radio signal in the same (or similar) frequency range as GSM communication. A cell phone jammer can block all radio communications on any device operating on a radio frequency within its range (that is, within a certain radius of the cell phone jammer) by emitting radio waves that prevent the target device from establishing or maintaining a connection.

Every technology has a good side and a bad side, what matters is how we use it. Like cell phone jammers, it's in the right place for the most part. But there's no denying that some people use it for bad things. Of course, today's detailed analysis of the applications and advantages of cell phone signal jammers. Cell phone jammer devices suppress cell phones by sending signals at the same frequency and high enough power that the two signals collide and cancel each other out. Cell phones are designed to increase power when they encounter major interference, so cell phone signal jammers must recognize and match the power increase of the phone. To block a phone, you need a device that broadcasts on an exact frequency. Although different cellular systems handle signals differently, all cellular phone networks use radio signals that can be interrupted. GSM for digital cellular and PCS-based systems operates in the 900MHz and 1800MHz bands in Europe and Asia, and in the 1900MHz band in the United States. Jammers can broadcast on any frequency and are effective for AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN and Nextel systems.

We use mobile phones to find signals every day, why do we need mobile phone signal jammers? In fact, there are two aspects to this fact. For people who can use mobile phones, of course, they hope that the stronger the mobile phone signal, the better. However, for prisoners, secret units and other special places, of course, it is necessary to effectively interfere with the mobile phone signal in order to do a good job of safety and absolute confidentiality. Take prison for example. For the prisoners held here, maintaining contact with the outside world is a must. Otherwise, how to accept the reform with peace of mind? In addition, there is no mobile phone signal, even if you have a mobile phone in your hand, you can't communicate with the outside world. Contact, reduce the occurrence of inappropriate things such as running away. However, there are still a lot of staff in the prison. They need to maintain normal contact with the outside world and accept the leadership of higher-level units. Their external contact is a must and it is their right. Here, the cell phone signal jammer system can effectively and targetedly block cell phone signals in areas that should be blocked, such as prison cells. In addition, the signal in other places can also be normal.
