How long does it take for the mobile phone to return to normal after the mobile phone signal jammer is turned off?
When the mobile phone is within the
effective shielding range of the mobile phone signal jammer, the phone's voice
call function and Internet data transmission and other functions will be cut
off, and the signal grid on the top of the display screen will also disappear.
At this time, the mobile phone is completely offline , Basic functions such as
answering or making calls, sending and receiving text messages, chatting
online, and playing games online cannot be used normally. At this time, some
customers will ask questions: If the mobile phone signal jammer is turned off,
how long will it take for the mobile phone to return to normal? Is it true that
the mobile phone signal will be restored immediately when the mobile phone
signal jammer is turned off?
The facts may be different from your
initial assumptions: the mobile phone signal jammer has two different states of
action on the mobile phone at the moment of turning on and turning off.
Let me first talk about what happens when
the mobile phone signal jammer is turned on: as long as the mobile phone is not
far away and does not exceed the effective shielding range of the shielding device,
then at the moment of turning on the mobile phone, the communication functions
(including voice and data) will be disabled. Immediately blocked, with almost
no time difference between the two. Although some people may find that the
signal grid does not disappear quickly or drop to zero when observing the
signal grid on the mobile phone screen, but in fact the signal grid at this
time is just a false display. Operate the mobile phone, trigger the external
communication function of the mobile phone, and you will find that the display
of the signal grid will quickly complete the status update.
Let's talk about the performance process of
the mobile phone signal jammer that was originally shielded by the signal when
it was turned off or cut off the power supply after the mobile phone signal
jammer was turned on for a period of time? Through observation, it can be found
that the moment the mobile phone signal jammer is turned off, the mobile phone
does not respond in a short period of time, and it is not possible to answer or
make calls immediately, and it is not possible to quickly use the mobile phone
to access the network. The signal grid is still displayed as no signal for a
period of time at the beginning. Mobile phone users can only see that the
signal of the mobile phone has finally recovered after waiting patiently for
more than ten or even twenty seconds, and then they can use the mobile phone
completely and 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, identification, and
registration to the network. The length of this process will be affected by
several factors. Factors, including: different operators of mobile phones,
different strengths of base station signals, different numbers of mobile phone
users in the service area to which base stations belong, and so on.
