A GSM jammer or GSM jammers is a device that sends signals at the same frequency as a GSM system. If the phone is disabled in the area where the jammer is located, the failure is successful. Signal interference equipment was first developed and used by the military. When tactical commanders use RF communications to control their armed forces, the enemy is interested in such communications. This interest comes from the basic realm of refusing to successfully transfer information from sender to receiver.
A Philadelphia man has sparked controversy after frequently using cell phone jammer devices on public buses to create cell phone dead zones. A NBC10 reporter in Philadelphia recently tracked down the man who used a GSM jammer on a bus to stop drivers from receiving cell phones. His reason-he didn't want to hear someone else's call. He said he turned on the signal interception device when other passengers spoke too loudly and bothered him. The man, Eric, told NBC reporters: "I think I have the law myself, and frankly, I'm proud of it."
There are different types of gsm signal jammers. More and more theaters or hospitals are using it. Jammers prevent your phone from receiving radio waves and receiving and making calls or text messages. If this is a way for event venues to win the respect of artists, it could be crucial for hospitals, as certain waves can distort results obtained using diagnostic or monitoring tools such as electrocardiograms.
