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 Florida man with a jammer in his car for months got fined $48,000. At least one priest has used a jammer after calls happened during sermons and even a funeral—and he supposedly got the go-ahead from the police.
Sure, the driver, and the... More

Any car equipped with electronic locks is at risk from signal jammers.
There has been an appeal for South Africans to help identify the person seen in the video about the signal jammer and how it works.
The video was shared widely on social media and quickly went viral.
It is unclear who this person is, but Crime in SA on Twitter plagiarized a post from the South African Police Service (SAPS) and appealed to South Africans to come forward with information about the person.
"Unidentified individuals are showing off signal jammers on social media. These devices are used by criminals to block tracking devices and cell phone signals. Let's help police identify this person of interest."
While some comments on the post claim possessing the device is not a crime, crimes in South Australia suggest otherwise.
“Some people are saying that this man cannot be arrested because he has such a device, let us put their doubts to rest. Failure to provide satisfactory service under section 82 of Act 129 of the Third Amendment Act 1993 reports of possession of equipment or items.
"Any person who is in possession of a device or article which is reasonably suspected to have been used or... More

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 standards and are illegal for use in the United States with few exceptions.
In this case, the FFC received an outage complaint from a telecommunications provider. In response, the agency's law enforcement... More

As drones rise, so does counter-drone technology. While a variety of potential counter-drone solutions exist, including surveillance equipment such as radars, radio frequency analyzers, or acoustic and optical sensors, as well as high-power microwave (HPM) equipment, drone networks, and lasers, there is another Solutions have been a hot topic for a recent problem in the drone industry: drone GPS interference.
Many drones rely on GPS (and other technologies like ships and cargo fleets, and even smartphones) for navigation and tracking. But some bad actors are trying to jam these GPS signals.
InfiniDome is an Israeli GPS security company founded in 2016 that makes a variety of products, but its focus area is building 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 GPS (GNSS) systems are vulnerable to jamming attacks.
Why does drone interference occur?
Why is it a problem?
There are many reasons why people would want to jam drone GPS signals, including defense applications, causing enemy drones to get lost or crash. While drones are used in... More

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 drone starts to react. It doesn't respond to your controls and seems to have a mind of its own. My friend, you may have just encountered a drone jammer.
- Simply put, a drone jammer is a device designed to... More

The purpose of these homemade devices was to jam the signals from kamikaze drones, but the radio transmissions protecting the tanks could also reveal the tank's location.
Russia's Lancet kamikaze drones, designed to locate targets and then crash, have become a serious problem for the Ukrainian military.
Drones buzz over the battlefield, flown by pilots on the ground and guided by radio signals.
Jammers mounted on tanks or other vehicles can interfere with the signal and cause the drone to miss its target.
Russia's invasion of Ukraine has intensified the drone arms race, with both sides using increasingly sophisticated drones for a variety of missions. The latest salvo is a repeating jammer that forms an invisible protective dome over the tank and jams the signals of any kamikaze drones trying to attack it.
The Lancet was made by Kalashnikov...yes, that Kalashnikov
One of the most dangerous types of drones on the Ukrainian battlefield is the kamikaze drone, which is designed for one-way flight and is launched over the battlefield. The pilot sits on the ground at the control station and must rely on the drone's camera to locate the target. When he does... More

"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. To this end, the Chinese military, whose electronic warfare capabilities lag behind Russia's, is purchasing Russian-made jammer device.
The United States also helped Ukraine find and destroy Russian jammers, a "high priority" mission, according to a... More

We are convinced that this was an act of pure, unadulterated charity, uninfluenced by self-interest. Cellphone jammer maker CellAntenna Corp. is calling on U.S. lawmakers to change federal law to allow law enforcement officers to use cellphone jammers more broadly. We bet you can guess why too – and yes, it’s helpful in the fight against terrorism. Because as we all know, there are a lot of cell phone terrorists out there (in fact, for us, anyone we see with a cell phone is automatically suspect). CellAntenna said in a statement that adding cell phone jamming is "the first step in increasing profits to prevent IED attacks in the United States." How refreshing - a company with a social conscience.
The company is challenging FCC rules on cell phone jamming devices
A small Florida company is asking the Federal Communications Commission to change a rule that bans the sale of cell phone signal encryption equipment to local and state governments.
CellAntenna filed a lawsuit in the U.S. Court of Appeals for the Eleventh Circuit in Atlanta on Nov. 22 challenging the Communications Act of 1934, which is enforced by the FCC. The 1934 Act and related FCC regulations prohibit... More

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 States unless you work for the government. If approved, though, it could help shoot down drones at airports, protect soldiers from drone bombs and help in situations where they simply can't get close.
Drones can use... More

Twenty years after the worst attack to ever occur on U.S. soil, it's not just large, populated passenger planes that keep officials and experts up at night, but also the threat of smaller, readily available unmanned aerial systems capable of carrying deadly payloads through the skies of an unsuspecting nation.
Drones are not tomorrow's weapons of mass destruction. They're here today, and the technology required to fashion such a device is only getting cheaper, smarter and more accessible.
One U.S. military official who requested anonymity paints a potential nightmare scenario involving small drones, referred to as unmanned aerial systems, unmanned aircraft systems, or simply, UAS.
"I kind of wonder what could you do if you had a couple of small UAS and you flew into a crowded stadium," the U.S. military official told Newsweek. "That could cause a lot of damage and it's a scenario that could potentially be in play."
While "no specific knowledge" of an active threat was discussed, the U.S. military official said that "there is concern given the proliferation of small, portable drones, that explosive drones could cause a mass casualty event."
It wouldn't be the first time the nation had... More
