Basic principles and efficacy of wireless signal jammers
Basic principles of wireless signal jammer:
Now our mobile phones contact the base station by increasing the frequency, which then transfers the signal to the mobile service switching center. When in standby, the mobile phone contacts the base station through the broadcast control channel. Once a call is needed, first ask the business channel for instructions based on the specific conditions of the channel near the terminal, so that the mobile phone jumps to the business channel to realize calls and data transmission.
At the same time, 4G wireless communication must ensure a sufficient signal-to-noise ratio to effectively receive and complete communication.
Then, based on the above working principle, we can obtain 4g wireless signal shielding, which is generally composed of a power supply, electronic scanning control unit, segmented radio frequency module unit, amplifier unit, transmitting antenna unit, etc. The signal generator generates a scanning signal, enters the oscillator and adjusts it to the mobile communication operating frequency band, and then amplifies the voltage and controls the power through the power amplifier. The amplified scan signal is transmitted into the air in the form of radio waves.
Features
The trailer design can be installed in the car, or can be replaced on-site with the vehicle for temporary installation and use;
Ultra-wide band shielding coverage, which can continuously shield wireless signals in all commonly used frequency bands from 20m to 3000mHz;
The modular design of the internal structure can be combined in any way, and channel 0 can be switched independently and has a fault alarm function;
Each channel module can be turned on/off independently;
Efficient frequency division makes the equipment better at interfering with signals of different frequencies;
Reasonable power distribution minimizes power loss and greatly improves efficiency; the power can also be adjusted according to on-site needs (select the gear adjustment);
The wireless signal blocker cannot receive normal 4G data sent by the base station, making it impossible for the mobile phone to establish normal contact with the base station and separating the mobile phone from the base station communication network. The mobile phone shows no signal, no service system and other search networks, achieving a blocking effect.
