Let’s talk about the behavior of the surrounding mobile phones that were originally shielded by the signal when the signal jammer is turned off or the power is cut off after it has been turned on for a period of time.
Through observation, it can be found that the moment after the cell phone signal jammer is turned off, the mobile phone does not respond in a short period of time. It cannot answer or make calls immediately, nor can it quickly use the mobile phone to access the network. The signal grid is still showing no signal for a period of time at first. Mobile phone users can only wait patiently for more than ten seconds or even twenty seconds before the signal of the mobile phone is finally restored. Only then can the mobile phone be used completely normally.
Why is this so? This is because after the mobile phone signal jammer is turned off, the signal recovery of the mobile phone must go through a process, that is, the process of handshake communication between the mobile phone and its surrounding base stations, identity recognition, and registration into the network. The length of this process will be affected by several factors. The influence of factors includes: different operators of mobile phones, different strength of base station signals, different number of mobile phone users in the service area of the base station, etc.
