Should the country intervene in the purchase of jammers?

At present, the main principle of signal shielding and cell phone jammer is to emit huge noise in the frequency band used by mobile phones, interfering with the reception and transmission of normal signals of mobile phones. The gadget is often used not only to prevent cheating on exams, but also to prevent terrorist attacks, politically and militarily. But a signal jammer is not like a grocery store. It’s not something you buy and use casually.

Which means that while LMADIS apparently fried the circuits of the Iranian drone last week—the first-ever “kill” by a US directed-energy weapon—that’s not always the expected result. “The UAV will typically go into some kind of default pattern, to return to base or to go land somewhere,” says Clarke. “The system is powerful enough that for a smaller UAV, if it gets close enough, the energy from the jammer will disrupt the electronics on the drone, and cause it to just fail. But normally the signal jammer would be used just to jam the communications.”

“The first NGJ-MB pod is out the door,” said Stefan Baur, vice president of Raytheon Electronic Warfare Systems. “We are one step closer to extending the Navy’s jamming range and capability. Delivery of this pod will allow for the initial verification of ground procedures, mass properties, aircraft installation, and Built In Test checks in preparation for future chamber and flight test.”The purchase or usage of jamming technologies only applies to public order, national defense and security needs or public law enforcement in accordance with local regulations.DroneGun MKII is a drone jammer providing a safe countermeasure against a wide range of drone models, allowing a controlled management of drone payload such as explosives.

If permitted, the school will jam cell phone frequencies during class time but not between classes or during lunch. “We believe that there are times during the school day that parents need to have access to students and students need to have access to family members, and doctors and things like that,” said Hook.Canada had considered allowing blocking in similar situations. But Industry Canada, which regulates the country’s telecommunications, decided against it, saying the devices could infringe on personal freedom and affect public safety by crippling communication with law enforcement and security agencies.
