1. What is a full-band jammer?
The full-band jammer is a device that interferes with the communication between the mobile phone signal and the base station when the mobile phone receives the signal. They were developed for military and law enforcement use against threats such as explosions and violence from cellphones.
2. How does the full-band jammer work?
It blocks radio frequencies in a specific area, causing signal traffic jams and thus blocking all communications. Like a radio silence bubble, the user cannot send or receive phone calls or texts as long as it is within range of a full-band jammer.
3. So why use a full-band jammer?
Proponents of the technology argue that full-band jammers are necessary when people fail to observe widely accepted proper cell phone etiquette. Come to think of it, school, theatre, transport, or otherwise quiet train, just about any conversation, text, streaming, etc. can be considered disruptive, even dangerous.
Remember, the full-band Car GPS Jammer will not only block the voice and text on your mobile phone, but also interfere with GPS, radar and police radar which may cause serious problems. Because of this, the federal government prohibits the sale, promotion, and use of full-band jammers in the United States. So, if you're looking for some peace and tranquility with your shiny new full-band jammer, you might just have to settle for earbuds.
4. How to detect the interference signal?
You guessed it, the most common symptom of full-band jammers is service outages. While some apps claim to be able to detect jamming signals, most of them are unproven and require a working signal to function. In the absence of advanced military technology, the average user can barely detect cell phone interference clearly.
5. How to prevent noise signal interference?
Blocking full-band jammers is not a viable option unless you can actually find the jammer itself (which usually looks like a walkie-talkie, cell phone, or cordless phone) and disable it.
Assuming you're tech-savvy enough to switch your phone's operating frequency, you can also avoid full-band jammers. But it does rely on jammers to block complex signals.
When you suspect that you may be the victim of a full-band jammer attack, walk away. The spread range of a full-band jammer is generally no more than 300 square meters, so being far enough away from your current location is usually enough to evade it.
