Signal Jammer Tech

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

An effective 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...

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.

In addition to this. Cell phone use in classrooms is now so rampant that the students now think they have a right to use them during class. They are not listening to instruction and directions need to be repeated many times because they were texting, listening to music on their phone playing a game or watching a video or movie. Some students have even taken or made a voice call during class. In this case, the phone jammer should be used..  

A test day was particularly memorable. One of the members of our group was a former Vietnam helicopter pilot and a member of the National Guard. He received a helicopter and a copilot in Richmond and flew to Dahlgren. It landed between the cedar trees and the power lines behind our trailers, which were in the then isolated area where the 1490 building is located (see Figures 1 and 2). These helicopters had clip locks on the sides to attach stretches for medical evacuation. We designed a frame to attach these latches that could hold our jammers, power supplies, and antenna structures. After the helicopter landed, we screwed on the system, loaded the instrument and scope cameras, and were off (see Figures 3, 4, and 5). There were teams on the ground to receive the jammer signals and also some enemy receivers that were being tested for effects.

The devices pose serious social risks and are undoubtedly illegal to buy and use in the United States. The FCC is optimistic about persecuting someone who buys a GPS jammer and criminalizing anyone who uses one. But they're easy to buy online, and their proponents say they should stay that way. Numerous GPS jammers can be purchased from numerous online sources for as little as $ 50.

"GPS is so embedded in the transportation, manufacturing and economies of our societies that the risk is high," said David Last, an emeritus professor at Bangor University in the UK and a well-known authority on the criminal use of GPS jammers. "This is especially true for telecommunications: GPS is the ultimate timing source for most of our PBXs, the Internet, and US phone booths."

We made our way across the Potomac River and tested the water up close to make sure everything was working before heading higher up over Maryland. The jammers' exposure to noise caused the main warning light to come on, which made the pilots very nervous. So we had to make sure that this was a true false alarm before we could continue. For the actual test, we wanted to simulate a parachute fall in usable areas, so the idea was to hover and take measurements at several distances. I learned that hovering at high altitude is very difficult for a helicopter because there is no ground effect. If you are not careful, the rotor wash can kind of self-circulate and you will lose control. We had some eye-opening moments, but the pilot was very capable.

All of these systems are potential prey for misery, and that's mainly why they're illegal. But proponents of the devices say that they can serve a purpose and that people should have the right to buy them. And for the time being, they can.

While GPS jammer helps you protect your privacy, that alone is not a good argument for using a jammer. Anyone can hire a detective to search a car or personal belongings to search for GPS receivers.
