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.
