Hove bar blocks cell phone signals and is more social

A Sussex landlord built a "Faraday cage" around his pub to block mobile phone signals to encourage face-to-face conversation.

Steve Taylor has fitted silver foil to the walls and copper wire mesh to the ceiling at Hove's gin barrels.

He said he was tired of people coming in and not socializing with each other or other people in the building.

"I saw things gradually getting worse and I thought, 'I want to stop this,'" Mr Taylor told BBC Sussex.

"I want people to socialize with the people they're with, not with the people they're not with.

"I made the bold decision not to block the signal with mobile signal jammer, but to do what I could with a Faraday cage to get people talking to each other, and it worked really well, to be honest.

"I had a lot of copper mesh and I thought,I can put this on the ceiling."

"I'm looking into whether it blocks the signal, when you put the phone in it, it blocks the signal."

Mr Taylor plans to set up a mobile phone area outside, similar to the smoking area.

"Pubs have landlines when calling 999 in an emergency," he said.

"It's the same as the London Underground - no more dangerous than my pub.

"The response I got was overwhelming. People loved the fact that they could just take a photo and go out and sign in or check in," he said.

"I had a complaint from a customer and she got the signal. We moved her to another table."

Arrested for speeding trap 'jammer'

Device stops camera from taking speed readings

A motorist in south Wales has become the first person in the UK to be arrested for using an electronic jammer to confuse a speed trap.

South Wales Police found the driver with a laser diffuser device in his car under a campaign called "Security Camera Collaboration".

Also known as a wifi blocker, the gadget works by alerting drivers to a laser speed detector and temporarily preventing it from taking speed readings.

The car was recorded speeding on six separate occasions around Cardiff and the South Wales valleys.

However, its travel speed cannot be read due to the signal jammer device jamming the detector.

South Wales Police Sergeant Gary Smart said: "The driver involved has been arrested for obstruction of justice and has admitted the offence."

"Partners will not tolerate the use of such diffuser devices.

He added: "Clearly, people using such devices tend to drive without due regard for speed limits and prevent police officers from carrying out their duties."

There are 33 static speed camera stations and 41 traffic signal stations in the South Wales Police area.

Another 103 mobile stations and 11 mobile units are also used to catch speeders.

Complex devices that prevent the camera from reading data quickly can be purchased from specialized websites.

They work by sending a strong laser signal to a speed detector, which causes a temporary error in the device and prevents a speed reading from being made.

"While legislation has been passed to make the use of radar diffusers illegal, there is currently no legislation on laser devices," said John Rowling of Security Camera Partners.

"Although the government is considering this important issue.

"Using this type of device is extremely dangerous as it puts the safety of other road users at risk by giving drivers a license to drive at inappropriate speeds.

He added: "I hope this arrest will serve as a clear warning to those using such devices to allow them to drive beyond the speed limit."

Dewsbury driver who used speed camera jammer jailed

A driver who used a laser gps blocker to illegally block the signals of road safety cameras has been jailed.

Police say Michael Twizell, 58, used a device on the front of his BMW 3 Series to interfere with camera equipment.

Twizel, from Dewsbury Low Road, was driving the A658 near Harrogate last February when he passed a camera van.

He was jailed for three months at York Crown Court after pleading guilty to obstructing the course of justice.

Cameramen detected the wrong code and North Yorkshire Police launched an investigation.

According to police, Twizel installed jammers on the front of his vehicle to interfere with police camera equipment.

The latest news and stories from Yorkshire

After the hearing, Traffic Constable Andy Foss said: "The use of a device capable of interfering with police speed measurements is clearly a very serious matter, as has been demonstrated today."

He added: "I would advise anyone who might have a similar device installed in a vehicle to consider the consequences and strongly advise them to remove it to avoid future prosecution."

Twizel was also fined £1,500.

North Yorkshire driver jailed for using speed camera jammer

A driver has been jailed for two months for using a laser jammer to avoid being caught by speed cameras.

In February 2018, Nicholas Burke, 46, used the device to jam the signal from a police security camera van on the outskirts of York.

Police estimate his car was traveling over the road speed limit of 60 mph.

The former car salesman pleaded guilty to perverting justice at York Crown Court.

A portable jammer installed under the front grille of Burke's car prevented the quick readout.

Its use activates a code on the camera, indicating to police that an illegal jammer is being used.

More Yorkshire news

north yorkshire police said burke admitted in an interview that he owned the laser jammer, saying he installed it because he feared points would be deducted from his licence.

burke, from selby green, north yorkshire, has since quit his job as a ferrari salesman.

traffic constable andy forth said the jail sentence showed "the courts take a very pessimistic view of people using jammer device".

"the purpose of our enforcement convoy is to reduce road casualties," he said.

"as a result, the use of such devices to interfere with speeding enforcement (one of the top four causes of fatal and seriously injured crashes) increases the risk to everyone else using the county's roads and the communities they represent."

We have become very dependent on global positioning. A power outage will cost us billions of dollars. And there is no backup yet.

 

The dire threat of GPS could cripple corporate America

 

A growing problem for GPS: There is no backup system in the United States. Most of our critical infrastructure, including power grids, banks, transportation systems, and telecommunications networks, relies on GPS. In addition to traffic maps and other positioning services, GPS is used for high-precision timing required for high-speed financial transactions, wireless network synchronization, and grid synchronization. But the rising risk of severe blackouts has gone largely unnoticed. "I don't think GPS vulnerabilities have gotten a lot of attention because, unlike cybersecurity, there haven't been any major disasters," said Marc Weiss, a fellow at the National Institute of Standards and Technology.

 

GPS and other timing systems will become even more important to modern life in the future. With the rise of connected sensors, devices and machines (i.e. the Internet of Things), timing signals need to be more precise. A government report last year concluded that a lack of high-precision timekeeping systems could hinder the development of new technologies, such as instantaneous collision avoidance systems in cars or communication links in smart grids.

 

The United States is at greater risk than countries such as Russia, China, Iran, Saudi Arabia and the United Kingdom, all of which have some form of ground backup. GPS outages happen from time to time because the signal is weak and highly susceptible to interference. "Terrorists can just use a GPS jammers to carry out an attack," Goldward said. Each jammer costs less than $50 and is extremely difficult to track and stop. Note that companies such as Spirent UK provide equipment to assist in the detection of GPS interference to help combat such interference.

 

The Global Positioning System provides navigation for our ships at sea. It is at the heart of the new next-generation air traffic control system. It can even time-stamp the millions of financial transactions that take place around the world every day.

 

GPS faces threats from terrorists, rogue states and $50 cell phone jammer

 

Criminals, terrorist groups and rogue states, even those with a basic GPS jammer you can buy for $50 on the Internet, face extreme challenges, said Todd Humphreys, a GPS expert at the University of Texas. big risk.

 

"If you were a rogue state, or a terrorist network, and you wanted to cause some massive damage — maybe not an explosion, but an economic attack on the United States — that's what you might do." As a weakness," he told Fox News.

 

Humphreys was the keynote speaker at the UK ICT Knowledge Transfer Network's World Experts Conference in London. His predictions about the prospects for this emerging threat are dire.

 

In 2010, for example, British researchers aimed a low-altitude GPS signal jammers at a test ship in the English Channel. The results were shocking: the ship went off course without the knowledge of the crew. Passing false information about their location to other ships increases the likelihood of a collision. The communications system stopped working, meaning the crew could not contact the Coast Guard. The emergency services system used to guide rescuers is completely out of order.

 

Then there's the disappearance of a U.S. drone over Iran. Humphreys believes Iranian authorities confuse the ultra-sophisticated RQ-170 spy drone into landing mode by using simple jamming techniques. The drone's Achilles' heel? It has a civilian GPS system, not a military-grade encrypted model. It doesn't take much to blind it and force it down.

 

Another threat that is burgeoning is so-called "spoofing." Unlike gsm jammer, which block or scramble GPS signals, "spoofers" mimic information from satellites. It can fool an aircraft, ship, or other GPS-guided device into thinking it's somewhere, but it's not.

Organized crime is already trying to exploit this possibility, Humphreys said. A criminal gang may hijack a container truck full of high-value cargo and trick the owner into thinking the truck is heading to a predetermined delivery point instead of the gang's warehouse.

 

Hanvers: "Civilian GPS signals are completely open and vulnerable to spoofing attacks because they have no authentication and no encryption. It is almost trivial to imitate these signals and trick a GPS receiver to track your signal." Authentic ."

Hijacking a container is one thing. Deceiving the global financial system is another matter. Another emerging GPS threat, Humphreys warned in a speech in London, is global stock and commodity trading networks.

 

Every transaction is time-stamped using a GPS clock. Computer programs monitor these timestamps with millisecond precision. If something goes wrong, many projects will be taken off the market. Hackers could easily interfere with these timestamps, triggering trading procedures, causing sudden liquidity crises and potentially mini-market crashes, Humphreys said.

 

Manipulating time, then, pays high dividends. An unscrupulous trader or criminal organization can make millions of dollars by delaying time even by a fraction of a second.

 

"You're able to match prices between networks in a different way than anyone else in the world," Humphreys said. “Everyone else in the world might be off by 20 milliseconds, and you happen to know the actual time. So you can buy low in one market and sell high in another.”

 

These devices are illegal in the US, but can be easily obtained on the Internet for as little as $50. People use them to avoid tolls, to hide from the prying eyes of their spouses, or to use company vehicles for unintended purposes. This sometimes has unintended consequences.

 

Devices that interfere with GPS may actually have a legitimate purpose: to protect individual privacy, he said.

 

"People have a right to privacy in their own lives," he said. “However, having a small dot-sized GPS tracking device to be able to secretly locate them at your friends — they would want to resort to some kind of jamming or deception to defend against this invasion of privacy.”

Safety zealot hid a phone jammer in his SUV to stop other drivers taking calls

If you happen to notice a second-hand Toyota Highlander being offered for a quick sale in Seffner, Florida, you'll know exactly who it belongs to. A local man, Jason Humphreys, has been given 30 days to pay a $48,000 fine after being caught radio-handed with a high-powered phone jammer hidden under his SUV's front passenger seat. When he was pulled over by a squad of FCC agents and police officers, who had spent days tracking the source of the wideband interference emanating from his vehicle, he reportedly told them that he was "fed up with watching cell phone usage while people were driving." Unfortunately for Humphreys, the state of Florida deems it legal for motorists to engage in phone conversations while they're on the move, whereas it severely frowns on the use of unlicensed jamming equipment that can disrupt vital communications between emergency services. The only glimmer of hope for this grumpy vigilante is if he can write to the FCC and somehow stall the fine, but even then he'll likely still face a separate case raised by an even grumpier Sheriff's office.

Drones can defend themselves with an anti-laser jammer

Helios prevents laser weapons from locking on.

There are plenty of efforts to make drone-destroying lasers. But what about protecting those drones? Adsys Controls thinks it can help. It's making Helios, a passive jammer that confuses laser weapons. If it detects an incoming laser beam, it detects the traits of that beam (such as its pulse and wavelength) and interferes with them to prevent the laser from locking on and toasting the drone. The company won't say exactly how this interference works, although it may be a counter laser. The one certainty is that it's reliable -- this is "permanent protection" against subsequent lock-on attempts, not just a momentary break.

You may have to wait a while to see Helios in action, since there's no mention of contracts at the moment. Also, it's not certain how well this works. Can a laser target a part of the drone without the jammer catching it? And is the system quick enough to stop higher-power lasers that can burn a drone within a few seconds at most? Still, drones don't really have anti-laser defenses right now. Any protection is bound to be helpful, and Adsys' solution could be highly effective if it lives up to the hype.

Break-in suspects using cell-jamming technology to avoid surveillance camerasCell-jamming uses devices to interfere with radio or wireless signals.According to CMPD, thefts have figured out how to evade surveillance cameras in some home break-ins, utilizing technology in the process.

It’s called cell-jamming, and happens when a person uses a device to interfere with radio or wireless signals.

According to the Federal Communications Commission, “the use of a phone-jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There are no exemptions for use within a business, classroom, residence, or vehicle.”

Cell-jamming could happen from a device roughly 30 feet from the intended target, or home cameras.

Rogue toy drones - a hot Christmas gift this season and last year - are beginning to disrupt military operations at multiple bases across the country. Sales of consumer drones are expected to approach 700,000 this year, and military officials say they are bracing for the problem to get worse and fear a possible aviation disaster.

How to stop terrorist attacks using commercial drones

In June 2015, an Air Force KC-10 aerial tanker flying at an altitude of 3,800 feet over suburban Philadelphia was forced to take evasive action and narrowly avoided hitting a football-sized drone that passed within 10 feet of its right wing.

According to reports filed with the Armed Forces or the Federal Aviation Administration, there were at least 35 cases of small drones interfering with military aircraft or operating too close to military airports in 2015.

Previously, close encounters with rogue drones were almost unheard of. But rapid advances in technology and falling prices have led to a boom in sales - and a corresponding surge in reports of air traffic chaos.

According to Federal Aviation Administration (FAA) guidelines, drone pilots flying for recreational purposes should keep their aircraft below 400 feet and at least five miles from airports. However, regulators have been largely unable to enforce these guidelines.

How does GPS/GNSS apply to drones?

Unmanned aerial vehicles (UAVs) are increasingly being used for a wide range of applications, including reconnaissance, surveillance, mapping, space information acquisition, and geophysical exploration. Often, in these situations, GPS is the key to safely operating the drone.

Drones are commonly used for Earth observation measurements, utilizing cameras and radars installed for this purpose. In order to accurately refer to the collected data, it is important to know the exact position of the vehicle when taking measurements or taking photos. A drone gps blocker receiver can pinpoint the precise location of a drone, often to the centimeter. The same concept applies to the exact time when a photograph is taken or a measurement is taken. The precise time stamp provided by the drone's GPS is invaluable for gathering such information.

 

 

They are cheap, lightweight and can carry small bombs; For groups like Hezbollah, Daesh (also known as the Islamic State, Islamic State, and ISIS), or any other group that wants to wreak havoc on budgets, commercial drones are essentially a new tool of terror.

"This is the quadcopter you can buy on Groupon or go to Sam's Club for $400," Gen. Robert Neller, Commandant of the U.S. Marine Corps, told a forum in Washington on the future of warfare.

Even before the Federal Aviation Administration unveiled proposed regulations for commercial drone flights in the United States last week, one company was already using drone jammer to collect data from unsuspecting citizens in Los Angeles.

AdNear, a Singapore-based location-based marketing company, uses a fleet of off-the-shelf consumer-grade drones to determine the location of a cell phone jammer and its movement by collecting signal strength and other wireless data from passers-by below. With this data, AdNear can offer highly targeted advertising and other promotions to potential customers as they pass through the storefront to incentivize customers to come into the store.

While collecting data from wireless transmissions via drones may be a new concept for marketers, Black Hat hackers have taken an interest in it, having demonstrated the ability to snoop on phones and Wi-Fi networks by using drones to impersonate cell towers, other transmission endpoints.

A string of recent drone-related incidents, including the crash of a drone on the White House lawn in 2015, may not have helped.

The drones, which have varying degrees of advanced weaponry, are currently being used in Syria's civil war and in parts of Lebanon and Syria bordering Israel, where Hezbollah holds a dominant position.

One solution is to use electronic signal jammers to prevent drone operators from flying within a specific area, an approach that has been studied by the U.S. military.

These drones are highly advanced platforms with technology and a price tag that puts them out of reach for all but the most advanced militaries.

Many cheaper, lighter models were more readily available to the guerrilla masses.

Their simplest use is to spy on American activities.

But what worries U.S. military tacticians is their potential for modified, more lethal uses.

As British car thieves use GPS jammers to escape, it's only a matter of time before American scammers - and, ominously, terrorists - catch on.

 

Jammers emit low-power signals, creating signal noise and tricking GPS receivers into thinking the satellite is unavailable. They can be used to confuse police and avoid tolls, and some pranksters have also used them to annoy unsuspecting iPhone users.

But the real threat is unknown. Criminals can use them to hide their tracks from law enforcement, and some experts worry that terrorists could use high-powered jammers to disrupt GPS reception on planes or during military operations.

 

These devices pose a serious social risk, and their purchase and use in the United States is unquestionably illegal. The FCC is optimistic about going after anyone who buys a GPS jammer and will prosecute and jail anyone who uses one. Yet they are easy to buy online, and their supporters say they should stay that way. Fox News can purchase GPS jammers from numerous online sources for as little as $50.

 

"GPS is closely linked to the transport, manufacturing and economy of our society, so the stakes are high," said David Last, emeritus professor at Bangor University in the UK and a leading authority on the criminal use of GPS jammers.

 

"This is especially true in telecommunications: GPS is the ultimate source of timing for most of our phone systems, for the Internet, and for cellphones in the United States."

 

All of these systems are potential prey for signal jammers, which is the main reason they are illegal. But supporters of the devices say they can serve a purpose and that people should have the right to buy them. And, for now, they can.

 

perfectjammer.com, a Shenzhen-based company, sells cigarette lighter jammer for $99.99 for its satellite signal. perfectjammer.com offers shoppers free nationwide shipping through UPS, FedEx and other companies.

 

that GPS jammers can be stowed easily in a car or a bag and can help avoid spy detection -- say,  from a spouse who suspects infidelity and plants a GPS tracking device like the Zoombak in a car.

 

"Our new cigarette lighter jammer is designed to block all possible tracking systems as well as all civilian GPS systems, including GPS L1, GPS L2, and GPS L5. To run the GPS jammer, you simply turn on the switch at the top of the jammer."

 

But Bruce Romano, legal counsel for the FCC's Office of Engineering and Technology, said that's not a good enough reason to use jammers. Anyone can hire detectives to scan cars or personal belongings for GPS receivers, he said.

 

"In addition to breaking the law, or [criminals] thinking they can use them because customs won't detect them, there are all sorts of critical devices that could be affected and could have unintended consequences that could cause problems, and you have no idea that you caused them," Romano said.

 

The Air Force, which deploys and maintains GPS satellites, acknowledges that GPS systems are vulnerable because they are widely used by the public.

 

Of course, GPS and cell phone jammer are not the most advanced. These devices, which cause signal confusion and disruption, are actually similar to illegal cell phone jammers.

 

This risk is low for aircraft, which use ground-based radar for guidance and have backup navigation systems that do not rely on satellites. Military personnel use a dedicated GPS network. But GPS interference can still cause cockpit chaos, as pilots have to switch to a backup navigation system. Shipping that relies on GPS coordinates to locate ports could also face problems.

 

Ronald Repasi, deputy director of the FCC's Office of Engineering and Technology, said it is illegal to sell, import, possess or use GPS jammers in the United States, and he said the agency aggressively pursues those who use them. He said GPS jammers could pose a potential risk if used incorrectly.

 

"It depends on the capability of the jamming device," Repasi said. "High-power devices have a larger range and are more likely to cause interference over a wider area than low-power devices."

Service station thieves use car key jammer

Police have warned that thieves are using radio signal jammers to steal from cars parked at motorway service stations.

Thames Valley Police said the transmitters could be used to "interrupt" the signal for the remote key, thereby preventing the vehicle from being locked properly.

 

Police said 14 truck, van and car thefts had been reported recently, but there were "no obvious signs of burglary."

It advised motorists to check their vehicles before leaving them unattended.

 

Burglaries were reported in the Chieveley, Reading and Membury service areas on the M4 in Berkshire in the last two weeks of November.

How does a radio jammer work?

The remote key has a unique signal that is transmitted from the remote key to the car via radio waves. Portable jammer suppress the signal from the owner's key and interfere with this communication.

 

These devices can be used on a large scale, theoretically allowing thieves to cover an entire parking lot.

 

Potential thieves rely on drivers to press the lock button on the keychain but forget to double-check that the vehicle is secure, thereby leaving it open for easy access.

 

More modern vehicles that use keyless entry may also be vulnerable.

 

Car key Jammer: What you need to know

With tech-savvy thieves reportedly using electronic devices (" key jammers ") to prevent car locks, what do you need to know about this growing crime?

 

The transmitters, which are easy to buy online, can be used to interrupt the keychain's signal, meaning careless motorists will think their car is safe when in fact it is not.

 

This gives thieves an easy way to steal your belongings or even the car itself.

 

A relatively low-power gps blocker has a range of about 75m, which means that a considerable area (such as an entire parking lot) could be affected at the same time.

 

But wifi blocker wielding scammers can strike anywhere, not just public parking lots.

 

Deputy Chief Constable Matt Jukes, of the National Police Chiefs' Council, said although he believed the problem was minor at the moment, it was "a growing feature of vehicle crime".

 

"The Vehicle Crime Intelligence Unit is working closely and extensively with a number of partners, including the Home Office and car manufacturers, to develop solutions to prevent this crime now and in the future."

 

Loran Dover contacted the BBC to say the incident had happened to her on a residential street in Leeds.

 

"When I got up to get ready for work, I went outside and found all the car doors closed.

 

"When I knew I'd locked the car, I was mortified to think I'd just left it behind - I was staying at my boyfriend's house and had to leave Christmas presents in the car. But when we actually looked inside, the whole car was ransacked and everything of value had been taken.

 

"The police initially said they would not take any action. No one was even sent to check for fingerprints, because there were no obvious signs of a break-in. But when I called the bank to cancel my card, the thieves kept using it." Non-contact type. That's when the police really got involved and took the matter more seriously.

 

"They are currently watching CCTV and hopefully they will catch them."

By comparing these two devices side by side, M 27 and M25 are almost identical. From the installation bracket, CPU, wiring, and interference head, M-27 is no different from its brother. Blinder is ready to use out of the box, including all necessary wiring, external speakers, CPU, and two GPS shielding heads.

 

Overall, the M27 is a high-quality and high-performance wifi blocker

 

M27 is suitable for small vehicles with a smaller appearance. M47 is used to cover weak points of small vehicles or protect large trucks or SUVs.

Installation is almost effortless. By becoming slightly familiar with automotive electronic devices, amateur installers can easily connect the device. All you need is a power supply and a ground wire. It is easy to wire the signal jammers head through a firewall through telephone type connectors, which are small enough to pass through the smallest hole. Then the rest is to install the GPS interceptor head. This is where it's a bit difficult.

 

The installation brackets are independent of each other, which means that each side of the jammer head is supported by separate brackets. For normal operation, the jammer head needs to be completely straight and level with the road surface. This means that in order to install the pan tilt correctly, you must find 2 independent and completely horizontal surfaces on the car. If installed on the top of the bumper, this may be easy, but most people do not want to clumsily place two large cell phone jammer heads at the front of the vehicle. It is difficult to complete the correct head installation on many vehicles, which is why most Lens hood users create their own mounting brackets.

 

Once the head is installed correctly, M27 has made significant improvements compared to the old version. With a more powerful head and fully upgradeable CPU, this new device is ready for all new laser Radar speed gun developed. In most cases, this device will interfere with the LiDAR all the way to the muzzle. However, Blinder did encounter some interference issues.

 

For certain guns, such as the Ultralyte LR-B, occasional malfunctions may occur. Independent testing has shown that vehicles equipped with two gps jammer heads at the front of the vehicle cannot cover high reflective areas such as headlights. This is a particularly undesirable situation, as police officers are often trained to aim their headlights when they are unable to produce instant and fast readings. To solve this problem, a headlight laser protective cover may be needed. Laser veil is a liquid coating applied to headlights. Applying this technology to the headlights will greatly help Blinder achieve better interference effects.

 

Another solution is Blinder M47. This is the M27 with two additional interference heads. If users encounter interference when using the M27, two additional heads are very suitable for achieving better results. Two additional jamming heads will enable the vehicle to be bulletproof against most laser Radar speed gun in almost all cases.

Until recently, satellite navigation system outages in populated areas were a rare and sometimes sensational phenomenon that caught everyone's attention on social media and the news. Yet such incidents seem to be becoming the daily norm. With the invasion of the Kremlin region on the night of May 3, the era of "GPS failure" suddenly began (in every sense of the word). The public immediately blamed this on the machinations of "Bandra".

 

Drivers in central Moscow learn to fool GPS jammers

 

Then there were problems with car navigation and car-sharing services in the city centre. Russian intelligence quickly deployed "phone jammer" to jam GPS/GLONASS signals in the area, effectively jamming the guidance systems of any drone that tried to replicate its early May night adventure. Now, if you rely solely on your smartphone's navigation system, you might mistakenly think that a person is somewhere on the outskirts of Moscow.

 

The situation is expected to worsen as the Russian government is seriously considering giving large private and public companies the legal right to use electronic warfare systems to protect their facilities from drone attacks.

 

This means that in the near future, navigation "failures" related to satellite signal outages will be observed near important targets such as oil refineries, power plants, defense enterprises and other strategic targets. Of course, beating an industrial-grade electronic warfare station with a traditional smartphone is unlikely.

 

However, there are opportunities to mitigate the negative effects on personal navigation. We clarify that this is quite feasible in a noisy metropolis. In small, sparsely populated areas, this may not be necessary, as disorientation is generally less important.

However, in a large city affected buy jammers, motorists must find alternative "coordinate systems" for their navigation devices. Fortunately, this possibility already exists. Location-based services (LBS) technology has been around for a long time, allowing you to determine a user's geographic location based on signals from cell towers and Wi-Fi routers at known locations.

 

In order to eliminate interference when the coordinates are accurately determined, the user must manually turn off the reception of the GPS signal and activate the LBS function in their gadget (if not already enabled). While LBS can't provide the same accuracy as GPS/GLONASS signals in more landmarked urban environments, it can certainly help users get to their destination.

 

Russian electronic warfare (EW) forces are effectively jamming the GPS signals of Western-supplied equipment for the Ukrainian Armed Forces (AFU), often even equipment previously considered invulnerable. This is written by the British edition of The Economist.

 

The Economist declared that Western technology was effective in jamming radio frequency armed forces signals

"GPS is operated by the U.S. Space Force and is designed for the military. But the Russians routinely block the positioning systems installed on these weapons, sometimes even on models considered invulnerable, "the July 14 article said.

 

The authors explain that GPS satellites' radio signals are weak, which means the system's operation can easily be disrupted by competing noise. But according to a Pentagon report leaked this spring, which was cited by the publication, existing jamming filters do nothing to protect Western weapons in the special operations area.

 

It is important to note that there are multiple alternatives to GPS, but each has its drawbacks. It takes years to develop new guidance systems and upgrade existing weapons.

 

Earlier on July 7, former US intelligence official Scott Ritter said that the Russian armed forces were able to significantly reduce the effectiveness of the US HIMARS multiple rocket system (MLRS) supplied to Ukraine. He explained that air defense (air defense) and electronic warfare equipment can interfere with the GPS signal of the HIMARS missile, significantly reducing its accuracy. The same can be done with an ATACMS installation.

 

Earlier on July 6, Dmitry Rogozin, head of the Czar Wolves military Technical Center, said that the Russian military had removed almost the entire British Storm Shadow cruise missile from the line of contact. He said there was a GPS beacon inside the rocket, but it was blocked by the Russian armed forces. The projectile has been handed over to experts from the military-industrial Complex (OPK) to find an effective way to dispose of this weapon.

 

Earlier in the day, Russian Defense Ministry spokesman Lt. Gen. Igor Konashenkov said that Russian air defense systems shot down two Ukrainian Su-25 aircraft over the Donetsk People's Republic, intercepted four Storm Shadow missiles and four HIMARS multiple rocket shells, and hit the control center. Three Ukrainian brigades posts.

 

Russian President Vladimir Putin announced on February 24 last year the launch of a special operation to protect the Donbass, which continues. The decision was made against the backdrop of the worsening situation in the region due to shelling by the Ukrainian military.

Philadelphia (CBS) - What is a cell phone jammer? Why don't we all have one?

 

Dean Liptak, a Florida high school teacher turned professional wrestler, has had administrative and legal troubles recently. Imagine telling that person you forgot your science homework. Not for slapping a teen in desperate need of an attitude adjustment to the mat (although one can only imagine the fortitude it would take to not do it on a daily basis). Instead, he found a less aggressive but more illegal way to stop kids from checking their phones in class.

 

Liptak brings to schools cell phone jammer, radio frequency transmitters designed to block, jam or otherwise interfere with authorized radio communications. The device blocks cell phone signals and prevents teens from using their phones.

 

The problem is that it prevents everyone in the area from using their phones, including emergency responders. That's why you need to know that even though you can buy them on the Internet, federal law prohibits the marketing, sale, or use of jammers.

Mr Liptak is currently suspended without pay. He may need to find an easier job. Things like using pile drivers, choking bashes, and jumping brain damage to make a living.

 

A Florida teacher has been suspended for using signal jammers to prevent students from using their phones in class.

 

Teacher suspended for jamming mobile phone in classroom

 

Pasco County School Board members on Tuesday approved a five-day suspension without pay for Dean Liptak. Liptak did not dispute the decision.

 

Liptak activated the jammers in his Fivay High School classroom between March 31 and April 2, officials said. He later told school district investigators that he never intended to create a problem. He said he believed gps blocker were allowed as long as they were not done for malicious purposes.

 

Sheriff Kurt Browning wrote in a letter of reprimand that Liptak may have violated federal law by jamming signals that could interfere with others calling 911 in an emergency.
