The best operating principle of wifi signal jammer; the working principle of mobile communication is that within a certain frequency range, wireless devices (mobile phones, etc.) and signal towers communicate with signal towers through radio waves to complete data and sound transmission with a certain baud rate and modulation method. When the mobile phone communicates, it contacts the signal tower through the uplink frequency, and then transfers the signal to the mobile service switching center to realize the call. In the standby state, the mobile phone communicates with the signal tower through the broadcast control channel. Once there is a need for a call, it will first be assigned to the mobile phone service channel according to the specific conditions of the channel near the terminal, so that the mobile phone can jump to the service channel to realize calls and data. transmission. At the same time, wireless communication must ensure a sufficient signal-to-noise ratio to effectively receive and complete the communication.

The classification of portable frequency jammers is distinguished from the appearance, including: drag box, backpack, hand-held and suitcase wireless frequency jammers. These models all reflect the portability of the application form of the equipment. For example, the drag box frequency jammer adopts a trolley case structure, and relies on the rollers to realize the drag transfer of the wireless wifi signal jammer. The backpack frequency jammer is like a backpack, which can be carried by the user directly on the body. Handheld frequency jammers are compact and lightweight, and can be held in one hand. A suitcase-type radio frequency jammer is a device that is completely assembled in a suitcase and has high concealment and camouflage capabilities.

In addition, from the power size and coverage of the equipment, it can be roughly divided into:

1. Small-power portable jammers, which generally refer to the transmit power of each radio frequency module between 0.5-1W.
2. Medium-power portable jammers refer to those with a transmit power between 10-20W in each radio frequency band.
3. High-power portable jammers refer to the transmission power of each module between 50-100W.
