cell phone text jammer mask signals

The mobile phone fogger sweeps from the low frequency band to the high frequency band at a certain speed in the working process, and forms interference when the mobile phone receives the information signal. Normal data from base station cannot be detected, connection to base station cannot be established, no signal, no service status. For example, when a cell phone communicates with a base station, the signal fog acts as a messenger, deliberately making noise around you. The noise signal is so important that the cell phone can't understand what the base station is saying.

The cell phone jammer currently used in the exam hall are all full spectrum, which can interfere with all the 2G/3G/4G/5G bands of the three operators. WIFI and Bluetooth signals can also be blocked. That's how cell phone signal mixers work. However, electromagnetic waves vary in frequency bands from a few to a few hundred Hertz, each of which can be used as a communication signal. Is there a special frequency band in the examination room? The same is true of other radio communication tools, which are "born" in the context of dedicated band radio communication tools. The working frequency band of these devices is selected outside the frequency range covered by the haze mobile phone, and the mobile phone signal haze will not work on it. For this special radio communication tool, the examination room was specially equipped with a monitoring vehicle equipped with ADIO monitor for real-time monitoring of radio wave signals from unidentified sources.

So how does a Cell Phone Text Jammer work? Because these electromagnetic wave characteristics are almost large and small, « constantly moving vehicle detection, monitoring equipment can track the range function and signal transmitter signal of the force, and catch offenders using these communications tools to broadcast live. Today, drones are also appearing in school examination rooms, which can locate the signal faster.
