Most countries, including the U.S., use GPS jammer to thwart cell phone-triggered bomb attacks against government leaders. When President Obama walked down Pennsylvania Avenue after his inauguration, all cell phones were jammed in the area. The U.S. military uses jammers to stop roadside bomb attacks in Iraq. The U.S. Navy has entered the final phase of development […]

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 […]
Read MoreThe defense department is beginning to focus on the use of jamming equipment in the military
The data in the report will be used by BOP and the Department to understand the efficacy of micro-jamming, conduct further evaluation of jamming technology, and develop recommendations for strategic planning. Simply program a small microntroller to generate a random-noise base signal and possibly the serial control strings for the PLL chip and wire it […]

In January, Perfectjammer said its researchers installed the jamming technology in a utility closet adjacent to a 13-by-eight foot cell on the ground floor of the prison’s housing unit, according to the study. It successfully blocked cellphone transmissions in commercial bands between 700 and 2170 MHz, but did not disrupt commercial transmissions when monitored at […]

Analysis of aggregate cell phone jammer emissions at prison facilities is beyond the scope of the report, as aggregate analysis would require detailed knowledge of specific facilities’ physical characteristics, the exact placement of individual jamming transmitters within such facilities, and the exact electronic characteristics of the jamming transmitters. Also, you’ll need a good RF-testing equipment, an aluminium […]

A jamming pod is essentially filled with antennae and radar transmitters. This equipment is vital for a warplane to survive modern combat. The first fight of every mission — a bombing run, surveillance or dogfighting — is waged across invisible parts of the electromagnetic spectrum. Radar can overpower other radar, sensors can be spoofed with […]
Read MoreThe U.S. plan to set up a special electronic jamming forces
The Russian army has established a ground-based unit specializing in defeating enemy drones. The unit—the first of its kind in Russia—operates electronic jamming systems that, in theory, can sever the radio connections between unmanned aerial vehicles and their operators. The Russian military has been jamming some U.S. military drones operating in the skies over Syria, […]
Read MoreCell phone jammers are used by law enforcement forces
Federal government wants drivers to stop using, looking, and typing on their handheld devices or cell phones. On the other, the government is against a simple solution to guaranteeing people stay off their phones while behind the wheel. At the heart of the opposition to jamming is a concern that it takes away a drivers […]
Read MoreCell phone vigilante – signal jammer
Cell phone jammer is a device used to block mobile devices from receiving signals from their base stations. Cell phone jammers were originally designed for law enforcement and military use, so they could block communication between terrorists and criminals. They’re pretty common in prisons as well, where cell phones (obviously) aren’t allowed for inmates. Once […]
Read MoreSignal jammers create a quiet environment
This signal shield holster with signal isolation function, when you put the phone into the holster, the signal will stop transmission. This is a very gentleman’s way of shielding, neither disturbing others, nor let others bother you. In some scenarios, the signal is likely to cause unfair events occur, so most of people prefer to […]
