What is a cell phone signal jammer?
A mobile phone signal jammer ;is a device that blocks reception between cell towers and mobile phones. Developed for use by the military and law enforcement, these devices were originally created to combat threats like cell phone-triggered explosives and hostage situations.
How do cell phone signal jammers work?
Known as cell jammers, signal blockers, GPS jammers, or text stoppers, a cell phone signal jammer holds up the radio frequency in a given area, creating a sort of signal traffic jam that blocks all communication. Like a radio silence bubble, no calls or texts can be sent or received as long as the user is within range of the cell phone signal blocker.
So, why are cell phone signal jammers used?
Proponents of such technology argue that signal jammer devices are necessary for many places where humans just can’t seem to observe the widely accepted rules of proper cell phone etiquette. Think schools, theaters, vehicles, or an otherwise quiet train ride… pretty much any venue were talking, texting, streaming and the like might be deemed disruptive or even dangerous.
Keep in mind, that a mobile signal jammer will not only block voice and text on your phone, it also interferes with GPS, WiFi, and probably most problematic of all — police radar. That’s why, as mentioned above, the Federal Government has banned the sale, promotion, and use of cell phone signal jammers in the US. So if you were envisioning a little peace and quiet, courtesy of a shiny new signal blocker, you might just have to settle for earplugs.
