The signal of our mobile phone is strong and weak, which is not only related to the influence of local signal strength, but also related to our household appliances such as TV sets, air conditioners, microwave ovens, refrigerators, etc., which will affect the signal of mobile phones; some metals Things such as magnets, such as computers and remote controls, also have an impact on cell phone signals. There is also a confined space that also has an effect on the signal.
When the signal of the mobile phone is not good or even there is no signal, first of all, it is necessary to see if it is in the blind spot of the signal, and whether there is a cell phone signal shield interceptor device. Since the receiving signal of the mobile phone works by the propagation of electromagnetic waves, the base station establishes a connection between the transmitting radio wave and the mobile phone, thereby achieving the purpose of the voice call. Therefore, shield signal will have an adverse effect on the mobile phone. This kind of situation is common in the examination room. If the cell phone jammer is not turned off after the test, it will cause interference around.
At present, there is no real shield signal software on the market. The so-called mobile phone signal shielding software is just to satisfy everyone's hunting psychology. It is a kind of junk software that can only shield the mobile phone signal on the surface but has no effect at all. The cell phone blockers achieves the interference of the mobile phone signal through some technologies, thereby achieving the purpose of blocking the mobile phone signal.
