Mobile phones usually use low-frequency radio signals to send information. In the process, people may be exposed to harmful radiation, especially when streaming or downloading large files. Radio frequency (RF) energy mobile phones need to transmit information through radiation, and research shows that doing so often endangers your health. Current research has not proven that mobile phone radiation is harmful, but many studies have shown that mobile phones are closely related to people's health, especially children's health. I am. Several cities, including Berkeley and San Francisco, have now received notifications from the state government and advised citizens to stay away from mobile phones. Block Numbers On Lg Cell Phone Can solve the problem of mobile phone radiation when people sleep.

WIFI and GPS signals will also be interfered. First, you need to use the built-in antenna mini dual-frequency GPS jammer for charging to improve the charging effect. cell phone jammer

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 Block Numbers On Lg Cell Phone indoors, the wall may cause the glass to block the signal and prevent it from interfering with the signal in another room. First, when manufacturing GPS jammers, test them. 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.
