FAQs
What is a cell phone signal blocker?
A cell phone signal blocker is a device designed to disrupt cellular signals within a certain area, preventing mobile devices from maintaining a normal connection.
How does a cell phone signal blocker work?
It sends radio frequency interference on targeted bands, making it harder for nearby mobile devices to connect to cellular networks.
Where are cell phone signal blockers used?
Commonly use cases include examination rooms, meeting rooms, workplaces, and other areas where mobile connectivity may need to be restricted.
What can I use instead of a cell phone signal blocker?
For applications where jamming is not permitted, consider non-RF alternatives such as phone pouches, device lockers, phone storage systems.
