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 […]
Read MoreSoon it will be perfectly legal to use jamming devices in the United States
However, some states are proposing legislation, like in California, that would allow firefighters and authorities to take down drones if they are interfering with an emergency situation like a wildfire. Blocking approach paths to airports, hovering over fires, and flying over freeways could be considered instances where those drones can be shot down. However, whether […]
Read MoreCellphone jamming devices are needed by educational institutions around the world
The government told a three-judge bench headed by Justice Dipak Misra that installation of jammers in school buses was “not possible” and they were coming out with steps to deal with the menace of child pornography in its entirety. A school there recently tested a cell phone signal jammer to get kids focused on academics, but admitted […]
Read MoreThe 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 […]
Read MoreThe next generation of jamming weapons is coming
Jamming involves pumping out RF in the frequency range they are using enough to overpower their own signals. So, you need power and you need to know the frequency range. Since RF drops off as the square of the distance, unless you can aim it very carefully, you have to be close or have lots […]
Read MoreCountries are pursuing jamming weapons with a wider range of radiation
Sometimes the jamming signal arriving at the receiver input, can be lower than the communication (“partner’s”) signal and still prevail. This is happening because usually the receiver needs a certain “margin” between the two signals at its input, in order to be able to interpret one of them (usually the stronger one). However, in advanced […]
Read MoreSyria 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, […]
Read MoreHaving 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 […]
Read MoreMost 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 […]
Read MoreSmart 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 […]
Read MoreSome 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 […]
Read MoreJamming devices are gradually playing an important role in the civil field
As a boss or a manager, you’ll find it is a hard task to manage your employees and improve their working efficiency. They will try all they can to loaf on the job in a way you can’t catch or blame to. For an example, they will go to the bathroom to use their cell […]
Read MoreChina’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 […]
Read MoreThe 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 […]
Read MoreEducators 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 […]
Read MoreThe role of GPS jamming devices in personal safety
The gprs signal scrambler is designed to suppress the signal of the global GPS satellite navigation system in the range 1500-1600 MHz. GPS suppressor makes it impossible to control the movement of the car through GPS navigators, as well as GPS bugs and GPS trackers, while the lock does not interfere with the operation of cell […]
Read MoreMore and more attention has been paid to the use of jamming devices
It is easy to prove if a jamming device is being used. If you are receiving the vehicle and tachograph data, you will know if the wheels are turning and the vehicle is moving, even though the tracking system will not be reporting any positional data and/or there appears to be a poor GPS signal […]
Read MoreHow to rely on jamming devices to maintain social equity?
Although it is unclear whether there is only one person involved in the Internet cheating, it has become a national scandal. It also raises the question of how regulation of the torture exams, the main route to success in Japan, should take place in the era of popularization of smartphones and access to the Internet […]
Read MoreDistractions 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 […]
Read MoreGPS 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 […]
Read MoreRussia 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 […]
