When technologically advanced mobile cheating methods are widely used, the maintenance of discipline and order in the examination room will also increase the difficulty and pressure. can be completely eradicated. I believe this will be of great help in ensuring a fair environment in the examination room. Especially after being familiar with the working principle of shielding equipment, the performance advantages of professional equipment can be reflected from different angles. It is very helpful to strengthen the technical strength and application of the equipment. As we all know, the technical level of mobile cell phone jammer has been greatly improved, especially the application scope and field have been significantly expanded, and due to the mature conditions and technical elements in all aspects, it can also play a decisive role in solving the problem of signal shielding. The advantages of cell phone signal jammers are even more prominent. After all, after making full use of different shielding effects, you can provide a full range of technical support for activities that require shielding mobile phone signals, such as exams. Further familiarity with the working principle of the device will ensure that the function and function of the mobile phone jammer device can be fully utilized.
Installing a mini-listener on your phone is the most primitive method. A wired phone transmits an analog signal without encryption during a call, so truncating this signal can easily revert to voice. The mobile phone signal is sent wirelessly, and the sent signal is encrypted, and decryption requires more attention. Still, phone hacking happens recklessly. For example, installing a miniature monitor on a mobile phone is the most primitive way of monitoring. But these days, most of them are not easy to disassemble all-in-one smartphones. Even if the back cover of the phone is opened, the parts in the phone are densely arranged. How can there be time to install bugs? (William Shakespeare, Hamlet) Cell phone batteries, for example, can only be made in half, so there’s plenty of room. However, the transmission distance of this eavesdropping method is mostly about tens of meters. That is, if you want to eavesdrop on a cell phone call, you have to be within range and it is no longer effective. Now the disassembly of the overall mobile phone jammer is more troublesome, so this method is not practical in today’s society.
