Nowadays, with the rapid development of communication, the communication between people has become closer, but communication technology has brought convenience to people, and also brought new challenges to communication security and confidentiality. In the past, there have been incidents such as wiretapping, leaking, cheating in the examination room, and gas station explosions. Prisoners using mobile phones can direct external accomplices to continue illegal activities from their own restricted confinement rooms. They plan to clear charges behind the scenes, order killings, and even contact outside accomplices for prison riots and escapes. The degree and seriousness of its harm has aroused great attention from leaders at all levels.
The high-power wifi signal jammer is a product developed according to market demand and adopts special advanced technology. The principle is that the signal of the transmitter or instrument is modulated between the two sides through a semiconductor device, isolated and converted by an optical or magnetic sensor, and then demodulated and converted back to the original signal before isolation, and the power supply of the signal is isolated at the same time to ensure the converted signal. Signal and power are absolutely independent. When it is in working state, it can form a shielding magnetic field within the specified range, so that the mobile phone cannot be taken out and accessed, so as to achieve the purpose of forcibly prohibiting the use of mobile phones, completely solve the various hazards caused by mobile phones, and enable people to enjoy high Technology brings convenience to people without disturbing the surrounding environment, completely eliminating the possibility of prisoners using network to communicate.
Friends who have cars should know that when going to the gas station to refuel, it is not allowed to make calls, because when the mobile phone battery is activated, it can generate enough energy to cause a slight spark, which may cause a fire. Relevant departments such as petroleum, chemical industry and security have expressly banned the use of mobile phones at gas stations. A few days ago, a man at a gas station in Myanmar was talking on his mobile phone, causing an explosion and fire. The explosion directly caused a brick house, 50 gallons of diesel and 7 car tires to burn, and the caller died of serious injuries... There have been many fires caused by the use of mobile phones across the country, causing many concerns. Relevant departments have suggested that gas stations within the jurisdiction use mobile phone signal jammers. Some regions have taken the lead in using wireless wifi bluetooth jammer at gas stations in some regions.
Each city and department can use a wifi signal blocker according to their actual situation. Its effective shielding range will be different in different places of use, and the shielding range of different types of mobile phones in the same place is not necessarily the same. Without affecting the normal use of public mobile communications, ensure the safe use of signal shielding equipment to meet your own needs.
