To block the failure of the mobile phone signal, you must first know the working principle and how to make the mobile phone have no signal. When To Use A Cell Phone Blocker The principle of shielding the mobile phone signal is to transmit the white noise interference signal with the same frequency as the mobile phone signal. When the signal strength of the cell phone jammer shielded mobile phone signal is stronger than the signal transmitted by the base station to the scene, then the mobile phone signal will be stronger than the signal transmitted by the base station. If it is completely covered by the signal that shields the mobile phone signal, then the mobile phone will appear to have no signal, or the service will be limited. According to this principle, cell phone signal interference is more suitable for this name. How can the mobile phone still have a signal without destroying and blocking the mobile phone signal?
First, reduce the power supply voltage for shielding mobile phone signals. When To Use A Cell Phone Blocker Generally, it is necessary to connect to AC 220V mains. For shielding mobile phone signals, there is a power adapter or switching power supply, which is converted into DC power. The power supply of the mobile phone is also 85-265V or 100-265V. If you want to shield the mobile phone signal from failure, then let the power supply voltage drop below 85V or above 265V. Of course, this method is generally not very easy to implement, it requires professional Only personnel can operate it, and attention must be paid to safety during operation. Second, it is possible to increase the signal strength of the mobile phone at the scene, so that the signal strength of the mobile phone at the scene is higher than the signal strength emitted by the shielded mobile phone signal, and it can also make the shielded mobile phone signal fail. This method requires the help of a mobile phone signal amplifier and a mobile phone signal amplifier. A receiving antenna is required, and the receiving antenna should be placed far away from the signal coverage of the shielded mobile phone signal to receive the mobile phone signal normally, otherwise it will still be interfered by the shielded mobile phone signal. Then place the transmitting antenna of the mobile phone amplifier at the site where the mobile phone signal is shielded.
