Now our mobile phone communicates with the base station 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 base station through the broadcast control channel. Once there is a call demand, it will be allocated to the mobile phone service channel according to the specific conditions of the channel near the terminal through the request, so that the mobile phone can jump to the service channel to realize the call and data transmission . At the same time, 4g wireless communication must ensure a sufficient signal-to-noise ratio in order to receive effectively and complete the communication. Then according to the above working principle, we can conclude that 4g wireless Cell Phone Jammer Chicago is generally composed of Power supply, electronic scanning control unit, segmented radio frequency module unit, amplifier unit, transmitting antenna unit and other parts. The scanning signal generated by the signal generator passes through the inverter, then enters the oscillator and modulates it to the working frequency band of mobile communication. cell phone jammer After the Power amplifier is amplified and the voltage regulator tube controls the Power , the amplified frequency sweep signal is launched into the air in the form of radio waves.
Wireless Cell Phone Jammer Chicago Because the frequency sweep signal forms garbled interference in the message signal received by the mobile phone (increasing the proportion of noise and noise signals to the device threshold), the mobile phone cannot receive the normal 4g data sent by the base station, so that the mobile phone cannot establish a normal connection with the base station. Separate the mobile phone from the base station communication network. The mobile phone shows the phenomenon of no signal and no service system in the search network, which achieves the blocking effect.
