Will mobile phone jammers affect people’s normal lives?

Inspired by the famous terrorist attack on September 11, 2001, modern surveillance has become a more important technology for protecting people from possible terrorist acts or deterring dissidents. Many companies are eager to provide a mechanism to ensure that their work is protected. Many of these technology companies have tools that allow the government to easily hack into personal phones and computers, as well as powerful cell phone jammer that can record all active Internet communications across the country. Beware of cybercriminals. The Wall Street Journal. Those who attended a secret security meeting last month obtained approximately 200 documents from more than 36 different organizations.

Different environmental interference effects are also different. The interference range in open areas is greater than in areas with many buildings. This is why the measured interference radius is usually better than the actual range. Because the test is in an open place. Since the signal will be blocked/interfered by stone walls, the grid forms a Faraday cage (including “fake” lead windows) and tin foil insulation and other metals, which interfere with indoor coverage areas, and the reliability of the equipment will be very low. This means that if you use a cell phone jammer indoors, the wall may cause the glass to block the signal and prevent it from interfering with the signal in another room. First of all, when manufacturing a mobile phone jammer, test it. There are many necessary tests, such as battery life, transmission frequency, etc., including interference radius testing. Because these devices are often tested in open areas, manufacturers always believe that the test results are more effective than actual conditions. You know that buildings and various concrete structures can interfere with signal transmission. Most of us live in big cities, surrounded by skyscrapers. The signal strength of the local mobile phone is also an influencing factor. Therefore, don’t be surprised if the interfering device cannot block calls within 30 meters.
