jammer

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.

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.

• 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."

Linking connection problems to signal interference can be difficult. However, if you notice these signs, you may be the target of this attack:

Your signal is good, but you can't make a call or send a message. The receiving bar may be lower than usual, but it's not bad enough to stop all communication.

The router didn't show any problems, but it couldn't get online. Your Internet connection may appear normal even if there is signal interference.

Don't trust apps that claim to detect interference. Apps that claim to be able to spot interference are often fake and will show false results.

If you suspect interference, stay away. Most cell phone jammer operate within a limited radius. Therefore, try to leave the area that appears to be affected. If wireless communication is normal, you may fall victim to signal interference.

Call your service provider. Other root causes can cause wireless communication to fail. Therefore, consult your provider for possible causes.

What is signal interference? Is it legal?

Signal interference overwhelms the target signal frequency and prevents nearby users from sending or receiving data. All devices that transmit or receive wireless signals over a particular frequency are susceptible to interference. Thus, jamming can target Wi-Fi, Bluetooth, GPS, and radio communications.

Because of its dangerous effects, jamming is illegal in most countries. If caught using jamming device to disrupt wireless communications, offenders face hefty fines and jail time.

In theory, signal interference can help designate phone-free zones, especially in schools. However, in most cases, the use of jamming devices is illegal.

In France, a man used a multi-band wifi blocker to stop his children from accessing the Internet at night. However, attempts to limit Internet use at home extended to neighbors, causing disruption.

For the disturbance, the man faces a fine of 30,000 euros and up to six months in prison. Therefore, even seemingly harmless use of interference can land you in hot water with law enforcement agencies.

How does signal jamming work?

Signal jamming is the deliberate disruption of communications by transmitting strong signals and overwhelming frequencies. Depending on its operation, jamming is a DDoS or DoS attack that stops a wireless exchange.

Also, intentional interference is important, because unconscious interference is interference. The latter occurs when the Wi-Fi signal is weakened by nearby devices using the same frequency.

A jamming device can be a relatively small device that broadcasts a continuous signal to block other transmissions. Some high-end products can cost thousands of dollars, but there are also some inexpensive devices. The following are the main types of jamming systems:

Handheld or portable systems may affect smaller areas.

Fixed signal gps blocker can operate within a larger radius and interfere with a certain frequency range.

Homemade devices that cover a smaller area may target one or two frequencies.

Signal jamming as a means of censorship

1. Government-ordered disruptions may cause users in specific areas to lose access to the Internet. In other cases, radio broadcasts from other countries may also be unavailable due to interference systems.


2. China has taken signal jamming measures to block radio signals sent by foreign broadcasters.


3. Iran launched satellite jamming to block BBC signals during the presidential election.


4. Russia has used multifunctional devices to disrupt communications in Ukraine.

Protect yourself from signal interference

• In addition to detecting when someone is trying to interfere with your signal, there are a number of prevention methods you can consider.


• First, you can change the Wi-Fi frequency and channel. Most signal jamming devices block the 2.4 GHz frequency. So, by choosing 5 GHz, you can restore your Internet connection.


• For home security systems, you can use tools that use proprietary algorithms that can identify interference. Such programs then alert the owner that someone is trying to interfere with the security system.


• Finally, if you are unable to send a message or call, you can try using a VoIP service. This should help avoid attempts to interfere with radio frequencies.

Tom's Guide tested an incongruous object: a cell phone jammer hidden in a pack of cigarettes.

There are various models, which are said to have a radius of action of 5 to 50 meters, and are sold for between 50 and 200 euros. The tested one is quite economical: 80 euros for a radius of 8 meters. Vicious: "Its makers have resized [the box] to make room for the two actual cigarettes in the pack".

The appearance and legitimacy of the product are not as good as it should be. "One thing's for sure, it didn't pass customs," the tester noted.

But why buy such a device? A salesperson interviewed offered some explanations: Some people disrupt communications in public transport, some teachers want quiet in the classroom...

It all started when two mobile operators reported mysterious disruptions to their networks in and around Clermont-Ferrand. ANFR then dispatched two agents from Lyon. Their measurements confirmed that the signal was interfering with the mobile network from Clermont, but locating the source of the interference was "like finding a needle in a haystack in a city of 140,000 inhabitants".

Investigators will get there. The roof of their laboratory vehicle is equipped with a radio direction finder, a device that can locate the direction of the transmitter and direct them to a building in Clermont. Six elite police officers from the Belt and Road (Research and Intervention Team) then intervened. Balaclava, helmet, assault rifle, they tumble into the apartment, and in the drawer of the TV cabinet, we find a multi-band gps blocker.
