The Federal Communications Commission says illegal devices that block cell phone signals could pose a security risk. The FCC has seen an increase in the sale of jammers devices that block cell phone calls, text messages, Wi-Fi networks and jammer GPS systems and could be used to wreak havoc in public places. The small, battery-operated devices can be used to create "dead zones" in a small area (usually about 30 feet) and are used by movie theaters, restaurants and schools to keep people away from their phones. But they also disrupt emergency calls, can disrupt navigation near airports, and have been used near police stations to disrupt radio communications. FCC officials said they have noticed an increase in jammers banned under federal law entering the country. Many cheaper versions are imported from Asia and sell for as little as $95, according to the agency. The sale, advertising, use or import of jammers is illegal under the Communications Act 1934, which prohibits ...

Cell phone jammers in the country's prisons are not enough to stop criminals inside from sending messages to others outside the prison. That's the view of senior prison officials, and while network jammers (which they say can be used) are used to block cell phone signals in prisons, other interception techniques are needed for the system to be effective. "Cellphone jammers are being used. However, to be truly effective they must be used in conjunction with other technologies such as WiFi jammers . We can see this happening in other jurisdictions. But it still needs to be used correctly here. "So some prisoners have mobile phones and tablets but are unable to make calls. However, you can use your phone's data allowance or if you have access to a hotspot device or WiFi box, you can also make calls through social media apps. This includes WhatsApp , Facebook and Instagram etc. So the problem of communicating with the outside world remains. Communication is stil...

Let's give credit to the teacher who destroyed the phone signal in the classroom. This is just a place that needs them. The news that Fivay High School teacher (and former professional wrestler!) Dean Liptak is in trouble for blocking cell phone signals in his classroom is completely the wrong reaction from the school administration (and let’s be honest, the government). Of course, what he was doing was technically illegal. The FCC says: "The use of 'cell phone jammers' or similar devices (signal blockers, GPS jammers or text message blockers, etc.) designed to intentionally block, interfere with, or disrupt authorized radio communications is a violation of federal law." Oops, It's not even illegal to sell jammers in the United States, but they're easy to buy overseas (as long as the retailer doesn't get caught). The only legal purchasers of such equipment are government employees. Liptak is getting off light (five-day suspension without pay); a Fl...

A signal jammer is a device that suppresses, interferes with or blocks radio frequencies, the use of which is generally illegal under the Communications Act 1934. This is primarily due to their ability to interfere with critical communications such as emergency communications, disrupt first responder communications, or interfere with maritime or aviation communications. Under the law, it is unlawful for any person to "willfully or maliciously interfere with or disrupt the radio communications of any station licensed or authorized under this chapter or operated by the United States Government." Additionally, the bill prohibits the manufacture, importation, sale, offer for sale, transportation, or use of equipment that does not comply with the provisions of the bill. Therefore, it is often impossible to authenticate or use jamming device because their real purpose is to disrupt the communications of authorized devices. Therefore, these devices do not comply with FCC standard...

As a professional photographer and drone pilot, I've seen firsthand how drone technology has become mainstream (pun intended) in recent years. But with great power comes great responsibility, and as our skies become increasingly filled with these high-tech devices, the need for regulatory and control measures becomes increasingly clear. Enter the world of drone jammers. In this article, we’ll explore the ins and outs of drone jammer , from basic functionality to legality. We will also discuss some practical applications of this technology. Whether you're a drone enthusiast interested in the technology, a security professional looking to learn about drone defenses, or just someone concerned about privacy, this guide is for you. Introduction to drone defense technology Okay, guys, let’s get down to business. What exactly is a drone jammer? Why should we care? What is a drone jammer? Imagine you are flying your drone and taking stunning aerial shots, and suddenly your dro...

"The U.S. military has invested a lot of work over the past decade to improve the security of GPS," said James Lewis, a technology expert at the Center for Strategic and International Studies, a Washington think tank. Lewis said Russia has deployed "powerful" jammers in Syria since 2015, disrupting much of the electromagnetic spectrum. These phone jammer are powerful enough to disrupt aircraft landing in Tel Aviv, Israel. “The problem with these large, powerful jammers is that they are vulnerable,” Lewis told Mission & Purpose. "It sends a strong signal, 'I'm here.' Target me." That's attractive when you don't have to worry about someone fighting back. I think that's one of the reasons it's used in Syria. " Russia also has more advanced jammers that can jam certain frequencies, Lewis said, and they have invested time and effort in developing the ability to spoof GPS signals and throw navigation systems off course. T...

The DroneGun interferes with robotic aircraft at a very safe distance There are a number of systems that can be used to shoot down wayward or dangerous drones, but they tend to have one big problem: You need to be relatively close to the drone, which can be scary if the robotic plane is packing explosives. DroneGun, a jammer gps that disables drone signals (including GPS and GLONASS positioning) from up to 1.2 miles away. Like most of its competitors, it doesn't destroy the target drone - it simply forces the vehicle to land or return to its starting point. Counter-drone teams can not only eliminate threats from a safe distance, but also locate their pilots. It's not the lightest machine, but it's portable enough for one person to use. You also don't need technical training, so it's easy for security personnel to use. Whether you see DroneGun running or not is another matter. It's not yet FCC certified, so you can't legally operate it in the United State...

As drones rise, so does counter-drone technology. While there are a variety of potential drone defense solutions, including surveillance equipment such as radars, radio frequency analyzers, or acoustic and optical sensors, as well as high-power microwave devices (HPMs), drone networks, and lasers, there is another Solution A hot topic in the drone industry recently: drones interfering with GPS. Many drones (as well as other technologies such as transportation and freight fleets, and even smartphones) rely on GPS for navigation and tracking. But some criminals are trying to jam these GPS signals. InfiniDome is an Israeli GPS security company founded in 2016 that produces a variety of products, but its main focus is on developing GPS signal protection systems. This summer, Infinidome published a white paper that clarified how drone gps jamming works and provided a very sobering demonstration of how vulnerable GPS systems (GNSS) are to jamming attacks.

The Russian Navy has installed temporary GPS jammers on at least one of its warships ahead of a high-profile naval parade in St. Petersburg, according to experts. An image published Wednesday by military and open source intelligence analyst H I Sutton shows a photo of a Russian Navy frigate taken in Russia's second largest city on July 14 that appears to show multiple sets of GPS network jammer installed on the ship's exterior. Newsweek could not independently verify the date and location of the video. However, military expert David Hamblin said the presence of GPS jammers on the ship does indicate that the Kremlin fears that Kiev, Ukraine supporters or anti-Putin groups will plot drone attacks. Samuel Bentt of the Center for Naval Analysis said it was "entirely feasible" that Moscow chose to use cell phone jammer and had done so before the war in Ukraine. But he told Newsweek that the evidence is limited and it's hard to judge. The drone threat: GPS jamming...

Bluelinx President Jeff Griffin said he is trying to sign up wireless providers as well as venues such as cafes and theaters. He says he hopes to start using the devices in the next few years. Unlike blocker device , he said, his call-blocking system is optional for cell phone users, who can turn it on or off. Others have the same idea, including companies and researchers who develop or already sell devices that make phones unusable in certain places. Methods include drone jammer that interfere with cell phone frequencies, routing systems that mute cell phone ringtones at specific locations, sensors that detect active phones , and building materials that block cell phone waves. Mr. Larson of the cellular industry group said that while the industry opposes controls on cell phone ringing, it is not opposed to measures that are left to the discretion of customers. "They're certainly less annoying than wifi blocker ," he said. Netline, an Israeli company, makes a detect...
