NBC News reports that online retailers and drone technology companies are marketing RF jammers as drone deterrents or privacy tools, thereby circumventing laws that prohibit the sale of such devices in the United States. The warning issued by the Federal Communications Commission (FCC) states that signal jamming devices can block emergency calls and pose a serious risk to public safety communications, while also interfering with other forms of everyday communications and air navigation systems. The FCC said: "It is a violation of federal law to use phone blocker , GPS blockers , or other signal jamming devices designed to intentionally block, disrupt, or interfere with authorized radio communications. Use in businesses, classrooms, residences, or vehicles is not exempt. Local law enforcement agencies do not have independent authority to use jamming devices; federal law enforcement agencies may use them under applicable regulations under certain limited exceptions." The FCC...

FLORHAM PARK, N.J. — Police in Florham Park, N.J., are warning residents that robbers may be using Wi-Fi jammers to prevent victims from using their cell phones to call for help. Floham Park Police are investigating an attempted robbery involving a Wi-Fi jammer A Florham Park resident was in his basement around 11:30 a.m. Monday when he heard a loud bang from the first floor, police said. When he checked his home security footage, he saw a stranger trying to enter his home. The man then lost service on his camera system and cell phone, according to police. Police believe the suspect used a Wi-Fi jammer — a device about the size of a smartphone that disables devices that use the signal. Police said the suspect ran away, and the victim, still unable to use his phone, ran outside and flagged down a pedestrian who helped him call 911. Officers arrived shortly after, but police said the suspect had already fled. "The victim had enough time to leave the area between the time he s...

Global navigation jamming will only get worse. The U.S. needs to move fast As geopolitical crises escalate, signal jamming and spoofing attacks on GPS and other Global Navigation Satellite Systems (GNSS) are becoming more common, creating significant challenges and risks to aviation, shipping, and other critical services around the world. Data from GPSJam.org confirms widespread GPS/GNSS jamming in parts of Europe and beyond as a result of the war in Ukraine. Affected regions include Finland, the Baltic States, Poland, Romania, and Bulgaria, in addition to the Black Sea, the Caucasus, and Turkey. The Middle East has also seen jamming due to hostile activities by Israel and Iran in the region. Other jamming activities, albeit on a smaller scale, are also common in Pakistan, India, and Myanmar. The Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS) provide critical positioning, navigation, and timing services to users around the world. However, like ...

An oilfield company faces a May deadline to contest a $126,000 fine assessed by the Federal Communications Commission against the company for jamming signal cellphone calls. that on April 9, the FCC adopted a notice of apparent liability against Taylor Oilfield Manufacturing Inc. of Broussard, accusing Taylor of using four cellular phone jammers to curtail cellphone use by employees. Company officials told the FCC the cell jammers , which disrupted cellphone usage, were used to prevent employees from using cellphones at work. Taylor was given 30 days from April 9 to pay the penalty or respond to the FCC in writing as to why the fine should be canceled or reduced. Taylor officials did not respond to phone calls seeking comment. The case began after the FCC received a tip and sent an agent to the company site in Broussard in May 2012. The FCC notice said company officials confirmed use of four cell jammers and possession of a fifth cell jammer, which was not then in use. Use of c...

We heard from our friend Charles Curry of Chronos Technology over the long weekend. He had a “yes and” to last week’s post about a jammer company with a new product line. – Full disclosure, Chronos has long be an RNTF corporate member. Charles is semi-retired but still keeps an eye on the jammer market. He and Chronos have quite the history detecting GNSS interference and recommending ways to mitigate it. They have worked with police departments advised governments, and published several papers. Their “Sentinel Project – Report on GNSS Vulnerabilities” was issued in 2014. Most of its findings and recommendations are as pertinent today as they were seven years ago. Here is Charles’ list of 100 active websites selling GNSS/ GPS jamming equipment, and a list of over 200 that used to do so, but that have links that appear inactive. Charles said there are more sites, he just stopped when he got to 100. – Yeah, a hundred ought to make the point reasonably well… FCC investigates Amazo...

NBC News reported that online retailers and drone technology companies are marketing radio frequency jammers as drone deterrence or privacy tools, bypassing laws that prohibit the sale of such devices in the United States. The warning issued by the Federal Communications Commission (FCC) says signal jamming devices can block emergency calls and pose a serious risk to public safety communications, as well as interfere with other forms of daily communication and air navigation systems. "The use of telephone jammers, GPS jammers , or other signal jamming devices designed to intentionally block, interfere with, or interfere with authorized radio communications violates federal law," the FCC said. "There are no exemptions for use in businesses, classrooms, homes or vehicles. Local law enforcement agencies do not have independent powers to use jamming devices; With certain limited exceptions, use by federal law enforcement agencies is authorized under applicable statute....

Glendale police issue warning about burglars using WiFi signal jammers to disable alarms, security cameras GLENDALE, Calif. (KABC) -- Glendale police have issued a warning about residential burglars who use WIFI jammers to disable security alarms and surveillance cameras. As described by police Sgt. Victor Jackson, the devices used by thieves block the signal or scramble the WiFi. "So if you have a Ring camera, a Nest camera -- any kind of alarm system that is WiFi-based or a camera that's WiFi-based -- it blocks the signal and knocks it out," he said. A disproportionate surge in residential burglaries plagued Glendale and Southern California in the fall, leading investigators to the crime trend. "As our detectives started going into these cases, that's when they realized what was happening," Jackson said. "In some cases, because of the way the device works, it made it look like when you went back and rewound your tape and looked, it wasn't a ...

Jammers don't target individual phones - they actually block all phones in the affected area. They drown out communications between cell phones and base stations by generating RF noise - the equivalent of you trying to talk to someone while I'm standing next to you screaming at the top of my voice. I doubt anyone is using jammers - jammers are uncommon, and the penalties for using jammers are quite severe in many places. Start by talking to your mobile carrier. If after all of this you still have reason to believe that jammers are being used, complain to the body responsible for radio and communication systems in your country - this could be the FCC in the US, or Ofcom in the UK - other countries will have their own equivalent. Someone used a signal jammer on me. How do I find it and stop it? I thought it was the same at my house where the signal was always down to 3g and I couldn't use the service unless I was outside. It turned out to be an IMSI trap installed in the ...

A Chinese government-affiliated trade body sought to purchase drone-jamming equipment for Russian buyers, but dismissed accusations, claiming the Russians tried to buy children’s toys, FT says. FT: China trade promotion body eyed drone jammers for Russia China’s Guangdong Province Trade Promotion Association for Russia, established under the guidance of the provincial commerce department, posted a “Notice of foreign enterprises purchasing [unmanned aerial vehicle] equipment” on its WeChat social media site, seeking “interference generators, drone detectors (trade names BorisTone, Assel Labs, Bulat) or other similar technological solutions, UAV suppressors, communication frequency band signal blockers ,” according to Financial Times. China claims neutrality in the Russo-Ukrainian war, positioning itself as an alleged proponent of peace. Despite this, it provides economic support to Russia, including drone technology and gunpowder ingredients, following the announcement of their “no ...
