The United States began research on jamming weapons decades ago

Communication GPS jammer devices were first developed and used by military. This interest comes from the fundamental objective of denying the successful transport of information from the sender (tactical commanders) to the receiver (the army personnel), and vice-versa.

Many teachers are fed up with trying to stop students from texting in class, and want to know how to stop cell phone use in the classroom.  Students ignore lectures while they surf social networks.  Some send texts, and even do research online, in order to cheat on exams.

The U.S. military is worryingly dependent on GPS. Our global positioning satellites tell planes where they are, provide targeting info for smart weapons, and support communication and navigation systems. But in a war with a tech-advanced adversary—think China, Russia, or Iran—GPS could become a big liability because it could be signal jammer, spoofed, or outright destroyed.

Back in the days of yore, in-class distractions were limited to things like seeing something out the window (SQUIRREL!), passing folded notes, or maybe sneaking in a comic book. Now, a student can do all that and a 1,000 other things on one screen. How does a teacher of any quality compete with YouTube, Snapchat, Trivia Crack, or even PornHub? Putting a filter on the local school Wi-Fi network doesn’t mean squat to a kid with unlimited data from mommy and daddy’s family plan.

GPS denial is a becoming a huge issue for American military planners. Peer states, especially Russia, are already putting GPS spoofing and jamming tactics to work during various training events near their own borders. We have discussed this situation in great depth before, and I would suggest you read this article to understand just how deeply the loss of reliable global positioning system data can mean for the U.S. and its allies during a time of war, as well as what is being done to overcome such a monumental hurdle.

There’s no question that in most offices, email and the Internet are absolute necessities. But are cell phones? In a survey by Pew Research, only 24 percent of adults with full- or part-time jobs listed a cell or smartphone as “very important” to getting their work done. In other research, 50 percent of bosses think a cell phone is a negative to workplace productivity.
