Cell Phone Scrambler Remote Control Jammers

If you are a teacher or a student that is tired of other students gabbing away on their phones during class time, a classroom cell phone jammer may be exactly what you need. With these devices, you can stop the conversations instantly, prevent students from cheating on exams, and stop class disruptions caused by cell phone ringing and buzzing. Adverse impact of mobile phones, of course, also more than that Studies have shown that long-term use of mobile phones tends to reduce attention. That's why education is often the main buyer of jamming devices.

A jammer is a device that prevents cell phones from receiving signals. The jammer used on the Red Line was the size of an old school Game Boy and had five antennas. To activate it, the man simply had to press a button on the top of the device and every surrounding call would drop. Just as a parent has the ability and right to cut off the Wi-Fi at home, they should have the option to cut the cellular signal if desired. Grabbing phones from hands to put them in airplane mode probably won't work, and making the house into a Faraday cage is an extreme only the tin-foil hat crowd should try. But an in-home cell phone jammer should be an option whenever desired or necessary. Concert goers, Broadway aficionados, film buffs, and many more would not need to worry about such rudeness if theaters utilized jammers that kicked in the second the lights dim. Sure, there's always emergencies, or doctors on call, or parents who must be sure the baby-sitter can reach them, etc. But those people should find a different way to spend their night out.
