Secret Service tests way to intercept rogue drones with late-night flights over Washington

WASHINGTON — The U.S. Secret Service will conduct mysterious midnight drone flights over the next few weeks in parts of Washington, often a strict no-fly zone, as part of a secret government test aimed at , find ways to jam or shoot rogue drones out of the sky.

A U.S. official with knowledge of the program said the Secret Service is testing drones for law enforcement or protection work and looking at methods such as signal jamming to stop the threat of civilian drones. The drones were flown between 1am and 4am. The official spoke on condition of anonymity because he was not authorized to discuss the plans publicly. The Secret Service said the details were classified.

Since January 1, 2018, importing and owning a jammer has been strictly prohibited in Switzerland and the countries of the European Union. The regulations for these devices, which are also known as "signal blockers" or "jammers", have been tightened up because the ban previously only applied to placing them on the market and using them. Jammers can be dangerous because they block all cell phone traffic, making emergency calls impossible. Most of the time, advertisements for these types of devices are deceptive: they give the impression that their use is legal, and fail to make it clear that even possession is illegal.

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.

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.

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.

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...

A truck driver was arrested on Monday for using a GPS jammer to hide his geographical location from his employer for several weeks, interfering with signals received by civil aviation at Lyon Airport

He blurred the path of the truck, as well as the path of the plane at Saint-Exupery Airport. A truck driver was arrested in Olins, south of Lyon, on Monday morning for using a GPS jammers to mask the geographical location of his professional vehicle, several sources with knowledge of the matter confirmed to Le Figaro. The National Radio Frequency Agency (ANFR) conducts 1,800 such incidents every year, and after an investigation, the suspect was arrested by police on the CRS highway. It is the General Directorate of Civil Aviation (DGAC) Lyon Airport that sees its GPS signal being interfered with at the same time every morning, thus issuing an alert. After a month of investigation, the direction finder - a circular radar placed on the roof of an ANFR vehicle - was able to isolate the HGVS travelling at the relevant time and identify their number plates.

Different countries choose different frequencies for mobile phone signal jammers

When you buy jammers, you should choose the signal jamming device according to the country you are in, because the signal frequency of each country is different, so the jammer you choose is also different. In this case, they can choose the signal jammer that suits them, because we know that there are different kinds of signal jammers, such as the EU version of the signal jammer and the US version of the signal jammer.

Now more and more people hope to obtain a signal blocker that can block signals in different frequency bands simultaneously or separately according to their needs. Now, in order to meet people's needs, more and more people have designed adjustable buttons and combined different jamming frequency bands together in one jammer to achieve their goals.

What is a radio jammer?

A jammer is a radio transmitter designed to interfere with, destroy, or block radio communication signals or services. In general, its role is to transmit a stronger signal than a useful signal on the target frequency band. Then the receiver no longer detects a useful signal.

Jammers often have a wider radius of action than people think or sellers suggest.

Why use cell phone jammers?

You know why a lot of people use cell phone blockers? In fact, there are many situations that may require a cell phone blocker.

When you hear about cell phone jammers with spy GPS trackers, it's clear that you have some negative impressions about using such devices.
