Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the transmission of data and sound is completed with a certain baud rate and modulation method. According to the above communication principle, the wifi jammers scans from the low-end frequency to the high-end of the forward channel at a certain speed during the working process. This scanning speed can form garbled code interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone shows phenomena such as searching the network, no signal, and no service system. In the end, the mobile phone has no signal and cannot receive text messages or calls.


We can compare a mobile phone to a radio for the time being. The radio often appears to be buzzing or the channel is simply confused and cannot be heard. This means that the signal is interfered. Since the radio can be interfered, so can the mobile phone. of and by some device interference.

8 Bands Jammer Device

There are many different names for mobile phone signal jammer, jammers, mobile phone jammers, signal jammers, mobile phone signal jammers, mobile phone signal blockers, mobile phone isolators, mobile phone blockers, mobile communication signal jammers, mobile phone signals Degree shielding instrument, mobile phone jammer, signal jammer, mobile phone blocker, signal blocker, mobile phone signal isolator, signal isolator, mobile phone signal interceptor, radio signal jammer. The military jammer scans from the low-end frequency to the high-end of the forward channel at a certain speed during operation. This scanning speed can form garbled code interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone shows phenomena such as searching the network, no signal, and no service system.


For the uplink and downlink channels of the mobile phone system, it uses frequency doubling, frequency division, frequency hopping filtering and other technologies to analyze the required shielding frequency; customize a spherical shielding space according to the power of the jammer, and automatically form a shielding magnetic field within the specified range , making mobile phones in this space invalid. When the jammer is in the working state, it can disable the signal receiving and sending functions of mobile phones within the specified range, making it impossible to dial out and dial in, so as to achieve the purpose of mandatory disabling.


The global positioning system (GPS), the space network that helps planes, ships and explorers orient themselves, could be disabled by gps jamming using cheap shop-bought equipment and information gleaned from the Internet, New Scientist magazine said.


The weekly said the U.S. Air Force formed a task force dubbed "Space Invaders" to look for weaknesses in the satellite communications and navigation system. The system is so popular now that even RVs and GPS watches use it for positioning.


Simulating a potential enemy, two novice technicians successfully assembled a satellite jammer GSM, relying on information downloaded from the Internet and materials purchased from general stores.


They assembled an ultra-high frequency (UHF) signal amplifier and noise generator for just $7,500. The device used copper pipes as antennas, plus some jumble of wooden blocks and plastic pipes, and was powered by an oil-fired generator.


They put the homemade device on an open pickup truck and turned it into a "signal cellphone jammer" that effectively blocked satellite dishes and the military's UHF receivers from getting the ultra-high frequency signals of the "Global Positioning System".


"Using a different component could interfere with GPS signals on other frequencies."
