Frequency 3G GSM Killer

One of the most popular things that are being used in the schools now days is the cell phone jammer. There are a lot of teachers and schools who think that school is an institution to learn and a device like cell phone can distract the pupils and interrupt in their studies. We all are aware of the fact the students defiantly are not be able to talk on the phone during class, but they can text their friends. A cell phone can be an easy cheating device where they can get the answers from a person who has the information or from the internet.

There are many uses for a signal jammer such as this. As pictured above, this can be quite useful for law enforcement as blocking cellular phones and GPS signals can help provide security. As such, they are often used by police and military and are also used inside jails to prevent prisoners from communicating with the outside.

Other common uses of signal jammers like these are to limit disruptions due to ringing cellular phones in places like movie theaters, libraries, schools, live theater performances, banks, hospitals, etc. A less common use is to block GPS signals when you go somewhere, in case you believe someone (i.e. spouse, police, private investigator, etc.) placed a tracking device on you or your vehicle. You can use jamming devices to prevent tracking.

Of course, GSM jamming devices are mainly used in civilian areas. For example, education institutions, conference rooms, libraries and other places need to be kept quiet.

When you are in the conference room, you can turn on the jamming device to ensure that there is no interference during the meeting.
