Portable jammer to keep quiet in the classroom

For anyone gearing up to deliver a speech to an audience, there’s always a chance they’re going to be rudely interrupted by someone’s mobile device going off. Ever since phones landed in the hands of the masses, there’ve been stories of theater actors pausing mid-performance to have a go at someone whose phone started sounding at a crucial moment of the proceedings.

There’s no clear FAA regulations for allowing police officers to interfere with or jam a drone in flight, but there are very real safety concerns that can arise from unauthorized drones, whether it be smuggling items into a prison or filming a secure location. And while things like the cell phone blocker may help with that, jamming devices are still banned under FCC code, meaning that regular consumers and even private security firms probably won’t be able to legally use one. That said, if regulations change and the jammers device can be legally used, it could be a helpful tool for improving drone security.

There are different types of cell phone jammers on the market today. Some devices can only block a single frequency while there are complex ones that can block several types of networks at the same time. The latter models can automatically switch from different networks to find an open signal. Higher end devices can block all frequencies at the same time while there are others that can be tuned to a specific frequency.

Use of mobile phones by inmates has been a menace that could not be controlled owing to the alleged connivance of some prison staff. Many crimes were believed to have been planned in prisons by gangsters who used mobile phones to communicate the plot to their henchmen outside.For those that are tired of hearing endless cell phone conversations or constantly being interrupted by incessant cell phone ring tones, a cell phone jammer seems like the perfect device to own. However, in addition to mobile jammers, what are the common jammers used for our lives?

For a simple cell phone jammer that will knock out the cell phones of the students in a classroom, you need a jammer that is very large or strong. In fact, you can likely use a pocket jammer, which looks like any ordinary cell phone, to keep the cell phones quiet in your classroom.
