Nowadays, various electronic devices are emerging in an endless stream. Some of them can even evade detection after being disguised. Cheating candidates enter the exam room to output the questions to the outside world, and then people outside the exam room help to answer the questions in order to achieve the purpose of cheating, and the basis of all this That is-it must be spread through the Internet! In this case, signal shielding is particularly important. How does signal shielding work? To put it simply, take a mobile phone as an example. The mobile phone needs to communicate with other devices outside the examination room through a signal tower, while wireless communication needs electromagnetic waves to carry. According to the characteristics of electromagnetic waves, both devices need to be within a certain frequency range. Sending and receiving, so Casinos Block Cell Phones is the frequency that affects your electronic equipment so that the frequencies of the two parties are different, so as to achieve the shielding effect. cell phone jammer

Dapower Casinos Block Cell Phones is a product developed according to market demand and adopts special advanced technology. The principle is to isolate and convert the signal of the transmitter or instrument through the semiconductor device modulation edge, through the optical sensor or the magnetic sensor, and then demodulate and transform it back to the original signal before isolation, and at the same time supply the power supply for the isolated signal. Perform isolation processing to ensure that the converted signal and power supply are separated. When it is working, it can form a shielding magnetic field within a specified range, making mobile phones unable to make or access, thereby achieving the purpose of forcibly banning mobile phones, completely solving the various hazards brought by mobile phones, and making people enjoy High technology brings speed and does not cause interference to the surroundings. The frequency range of the interference signal is within the receiving range of the pickup of the recording device.
