A misunderstood jamming device

When someone hears about cellphone jammers, you might have an initial overall negative impression. After all, why would someone want to cut off the communication of cell phone users? The reality is, there are really many reasons to consider using a cell phone jammer — and within a variety of settings. A Wireless Spy Camera Jammer will […]

The basic principle of interference arms operation

Simply put, they emit random static or noise on a sweeping range of frequencies, strong enough that a device closeby cannot connect to what it supposed to. Kind of like being beside a running car engine, with the hood open, while trying to talk to someone on the phone. The local noise becomes overpowering so […]

Syria is actively deploying jamming weapons defenses

As for the automated command and control system which might be deployed to Syria, my guess is that the Polyana D4M1 would be a prime candidate. Whatever the actual mix will be in the end, I would argue that this presents a more formidable capability than additional S-300 launchers. Sure, this is apples and oranges, […]

Having a new jamming technology means a huge advantage

Duke is an outgrowth of a U.S. Army development effort to defeat remote-controlled improvised explosive devices that began in 2005, known as Counter Radio Controlled Improvised Explosive Device Electronic Warfare, or CREW. The initial versions of the AN/VLQ-12 went into Humvees, MRAPs, and other Army armored and unarmored vehicles, to provide short-range jamming to prevent […]

Most countries approve of jamming devices

Though mobile phones have been banned in exam halls, a final year MBBS student of a private college had managed to cheat in a recently held exam through Bluetooth device and a microphone. “We have installed cell phone jammer in four examination halls for preventing cheating during exams. Instructions have also been passed to the invigilators to […]

Smart devices are threatening our health

Use of smart phones have a number of adverse health effects on children, childhood leukaemia, impaired motor function, delayed reaction time, headaches, dizziness, fatigue, weakness, and insomnia. So there should be a strict law in this regard. Jelianggao explained that though they strictly observe regulations in the facility, there are instances that they cannot control […]

Some countries are already using jamming techniques

At a March 11 soccer game in Wuhan, China, police faced a new kind of threat: drones trespassing near the stadium. Their response was to use a new kind of weapon: an anti-drone gun that jammed the control signals, forcing the trespassing drones to land automatically. Given China’s role as a global leader in consumer […]

China’s jamming technology could be the biggest threat to the United States

Beijing’s recent space activities indicate that it is developing co-orbital anti-satellite systems to target U.S. space assets. Co-orbital anti-satellite systems consist of a satellite “armed with a weapon such as an explosive charge, fragmentation device, kinetic energy weapon, laser, radio frequency weapon, jammer, or robotic arm.” Besides the “hard-kill” methods, Beijing is also testing soft-kill […]

The threat of radio interference to national security

One of the major concerns about the request from the GOP governors is that the technology they are asking for could be used to block public airwaves. This means that state or local authorities would have access to the type of technology that could shut down cellphone calls even outside of the prison. According to […]

Educators are in urgent need of jamming devices

Many educators are having trouble figuring out how to handle electronic devices in the classroom. Some have been educating students on the negative effects, encouraging them to regulate their own use. Others have even highlighted possible applications for mobile devices in the classroom. Though, many just try to ban everything. A principal in British Columbia […]

Distractions and anti-distractions — endless topics

Virtually all defense and security applications of GPS/GNSS require additional technology to protect assets and missions against signal interference, whether signal jammer or spoofing. The upcoming free webinar, Resilient PNT for Military Applications, gives a primer on several of these technology options. Mitigation in this context means that after isolating the unwanted signal, quickly rejecting and replacing […]

GPS jamming technology has commercial and military applications

However, integrity and resiliency are growing needs in commercial applications, especially ones that are in critical operations. Much more can be done to detect cellphone jammer and spoofing than what is in standards GNSS receivers today. The GPS signal jammer works by sending out its own signal on the same frequency as the GPS unit, a noisy […]

Russia has set up a special series of jamming weapons

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 signal jammer systems that, in theory, can sever the radio connections between unmanned aerial vehicles and their operators. NGJ-MB is part of the Next Generation Jammer (NGJ) system capability comprised of three stand-alone programs: NGJ […]
