Can mobile phone jammers selectively block numbers of different operators?
A fact about mobile phone numbers that
mobile phone users in various countries will know is that when selecting a
mobile phone number, the mobile phone number belongs to a certain communication
operator. The carrier provides and charges for basic communication services to
the mobile number. Usually, there are at least three or more communication
operators in each country. Assuming that in a usage environment, there are
mobile phone numbers of different operators, that is, different mobile phone
numbers, then the question arises: Can mobile phone jammers selectively block
signals for numbers of different operators?
To answer this question, you need to know
in advance which country you are in, and you need to know how many
communication operators there are in that country, as well as the division
standards of mobile phone frequency bands in that country, and which operators
specifically use when deploying base stations. frequency band. When the
information is fully grasped and handed over to our mobile phone jammer
manufacturer, then we can individually customize signal shielding modules for
different operators based on these frequency band division standards.
Therefore, in the process of implementing signal shielding, mobile phone
numbers belonging to different operators can be selectively shielded.
What needs special attention here is that
the shielding module in the mobile phone jammer can modulate the frequency
range. The so-called signal shielding for different operators is actually to
modulate the frequency of its shielded signal to the corresponding base
station. Frequency, only when the operating frequency of the operator is
strictly differentiated and there is no overlapping frequency band, the
shielding effect mentioned above can be achieved. In reality, operators in some
countries, due to the large number of communication operators and the tight
spectrum allocation resources, will appear that multiple operators share the
same mobile phone frequency. In this case, conventional mobile phone jammers
Targeted signal shielding cannot be achieved.
Another point needs to be emphasized: the
above is not a selective blocking of a specific mobile phone number. For
example, there are 2 different mobile phone numbers, but they belong to the
same communication operator. When within the effective shielding range of the
jammer, the two mobile phones will be shielded at the same time. Unless the two
mobile phone numbers belong to different operators, and the mobile phone jammer
installed on site happens to be a customized product, when the mobile phone
signal of the targeted operator is blocked, the two mobile phones will show
that one mobile phone can Normal communication, but the result of another
mobile phone not working normally.
