Cell Phone Blocker Using Arduino Uno The location of the device may affect Wi-Fi and Bluetooth. There is a principle that the radio frequencies emitted by the bail net are unreceivable. By transmitting a constant frequency signal, the signal interferes with the phone signal strength to cover a specific area of the phone signal. I can't communicate. That's why it can't receive. Let us understand the principle of mobile communication. It can be divided into multiple bandwidth channels, one of which is a very important channel, called the smartphone electromagnetic wave coverage control channel.
Blocking the cell phone signal is the act of temporarily disappearing or weakening the cell phone signal by using a certain device or method. It is mostly used for examinations in the education sector, state secret agencies and secret projects. Let me introduce to you today. Some methods and equipment for shielding mobile phone signals, I hope you can learn Cell Phone Blocker Using Arduino Uno related information through the introduction. There are many types of cell phone signal jamming devices, generally handheld, wearable and transmitters. The general shielding range of cell phone jammer on the market is a radius of 500 meters.
