With the popularity of mobile phones, the demand for mobile phone signal jammers in various conferences and exams has also increased significantly, and mobile phone signal jammer devices naturally have a broad market. However, most customers lack sufficient understanding of mobile phone signal jammers, and often choose high-power jammers one-sidedly in order to achieve good results, causing many hidden dangers. The principle of the mobile phone signal jammer is to use the broadband transmission interference signal to interfere with the uplink signal of the mobile phone, so as to achieve the function of shielding the mobile phone from working. Therefore, it is a signal emission source in itself. Since it is a signal emission source, there is naturally radiation. The transmit power of the current shielding device varies from 1W to 480W according to the needs of use. How strong is this transmission power? In contrast, the maximum transmit power of a GSM mobile phone is 2W, while the usual transmit power of a GSM macro base station is between 20W-40W. The transmission power of shielding devices generally used for exams and conferences is between 10W-60W.
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.
Honestly, since we developed cell phones, they have helped us a lot in our daily lives. Young people can enjoy entertainment life. brought a lot of convenience. However, using a smartphone for a long time is annoying for us. You need to use a cell phone jammer to fix this. What devices are interfering with smartphone signals? Does it work? I have a question like this. In fact, many countries are using such cell phone jammers. A device used to prevent the use of mobile phones. So far, it has a wide range of uses. With advanced technology, life has become very convenient. Use a cell phone jammer to protect your privacy. It is a device that temporarily interrupts the cell phone signal. The effective blocking range can effectively disable the smartphone. This cell phone signal jammer is easy to use. This device may cause communication methods to be blocked.
Almost everyone has a cell phone these days, the phone is ringing everywhere, and more and more people are tired of being interrupted by other people's calls and are looking for a solution. The solution is cell phone jammers. Cell phone jammers are used to temporarily interfere with cell phone signals within a certain range. It blocks the signal transmission between the cell phone and the base station. This is because cell phone jammers and cell phones work on the same frequency. But in order to keep cell phone signals from jamming, jammers should be regularly aligned with your cell phone. Once outside its interference range, the phone works fine. Provides the ultimate best solution in areas where cellular communications are generally not welcome. It stops the signal transmission between the cell phone and the cellular base station. Cell phone jammers block cell phones by sending out radio waves on the same frequency as the cell phone uses. When you turn on the cell phone jammer, all working cell phones in the area will display "NO SERVICE". You don't need to worry about other electronics as it won't interfere with non-cellular communications.
