Find out how cell phone signal jammers work, which are often used in prisons but can also appear in other places and events
Cell phone signal jammers are very useful devices in some specific locations, such as prisons and events that don’t allow for signal interference, such as high traffic areas or presidential inaugurations. In general, the operation of these devices is relatively easy to understand, as we explain in the following lines.

Signal noise disturbs the frequencies used for communication
Simply put, jammers are capable of emitting a very strong frequency signal to “congest” the spectrum that is usually used by mobile networks. In this way, mobile phones are without signal and incommunicable within the operating area of the device, something similar to what is done more focused on “weapons against drone“.
While the primary use of jammers is to prevent communication between inmates, they can be used in other places as well. Decisions approved by Anatel in early 2023 they will also allow them to operate in ports and airports, public safety areas and more.
Either way, using the choke usually requires a fair amount of planning to ensure it doesn’t do more harm than good. If not well regulated, the product can, for example, disturb residents close to prisons.
For this reason, the specialists carry out a detailed study of the environments and install an emission system within this place, with multiple points, almost like a mesh networkbut with opposite goals.
In addition to the signal of Internet connections, the equipment can also interfere with GPS, Wi-Fi and radar signals from security authorities. Therefore, its use is quite limited.
Currently, signal jammers cannot be used by individuals or businesses. Furthermore, their use without Anatel’s authorization constitutes “clandestine telecommunications activity”, with a penalty ranging from two to four years in prison.
Interestingly, the legislation is not as strict in some other countries. In France, for example, jammers can be used in venues such as cinemas, concert halls or other performance venues, all to ensure that audiences aren’t distracted by their smartphones or interrupting the presentation with unwanted calls.
