Is it possible to use two jammers in one building?

I guess if you ask such a question, then you know the basics, so I won't tell you what you already know. If you want to use two signal jammers in one building, there are many things to consider.
First, you need to determine if the jamming radius of your jammers will intersect. If so, they must work with different frequency bands to avoid mutual interference effects. If the jamming radius is not crossed between jammers, you can use two jammers of the same type. And if you use two different frequency-locked signal jammers, you can forget about worrying that they will interrupt each other's work.
So choose wisely and remember that there are jammers, such as the Adjustable Multi-Frequency Signal Jammer, which can act as a desktop signal blocker to cover the entire building.
If you have any additional questions on this topic or any of the jammer types, feel free to ask!
