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 phone jammer 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.
An effective cell phone jammer does not necessarily need to be outputting a significantly higher power level than the devices it wishes to jam. most Cellfones use CDMA technology which means they are all essentially broadcasting on the same frequency, but they are all synchronized with the base station and transmit different “codes” within that frequency to allow the base station to decipher them individually. However, a single rogue phone on the CDMA frequency that is constantly blasting out garbage noise instead of carefully synched CDMA codes will drown out its immediate neighbors…
The counter-drone system — for protecting airports and infrastructure — is the counter-UAV system, which combines radar, RF and optical sensors and a targeted jammer. Part of a modular family of products, includes various sensors such as radar, camera and radio frequency detectors and direction finders and jammers. It uses sensors to detect and identify a drone as far as several miles away. A jammer — using real-time signal analysis — then interrupts the link between drone and its pilot, or interferes with the drone’s navigation system.
The state government had earlier allotted Rs 5 crore for procuring 12 mobile phone signal jammer to be installed in various central prisons to control the use of mobile phones by the prisoners. Two mobile phone jammers had already been installed at the Puzhal Central Prison.
