Electronic jammers were introduced in the United States

We live in a society that thrives on cell phone usage. We keep them on hand 24/7 in case we need to look something up to win an argument, get an important text or email that couldn’t wait an hour for us to check, or take a selfie of whatever it is that we’re doing that we feel all of our Instagram followers should know about. Our cell phones have found ways to become a part of every single aspect of our lives. And while they have done a great job at connecting us with friends and family around the globe, and helping to organize our lives, we have all had movie experiences ruined by an overzealous texter.

When you turn on the device, it will block out signals at the frequency that cell phones generally broadcast. This will show up on the other person’s phone as a low signal, and he will have no idea that he is being jammed. The devices come with a rechargeable battery and can usually be used for up to two hours. Most of them also come with car adapters.

On Friday, divisional commissioner PV Jaganmohan held a review meeting with district magistrates of all four districts of Bareilly division on UPSC preliminary exam. The DM said that Bharat Electronics Ltd would install cell phone jammer at all the 37 exam centres. “It has been learnt that during various entrance and competitive exams, aspirants have been caught cheating using bluetooth and wifi enabled electronic devices hidden under their collars, inside a button of their shirts or in their pens. Now, even if a candidate succeeds in taking such a device inside the examination centre, he or she wouldn’t be able to use it,” the DM said. Two or more jammers would be installed at every exam centre depending on requirements.
