Quebec prison authorities will eventually be able to install military signal jammers in prisons to better prevent prisoners from smuggling cell phones. Canada will explicitly approve the use of this special signal jammer in prisons to prevent mobile phone smuggling and mobile phone external communications. Including one in Fresna, it is planned to invest 3 million euros in two regions of Ile-de-France to provide such military jamming equipment to 26 sensitive locations within three years.

Thanks to the invention of GPS jammer to make us safer

With the development of science and technology, people have invented many new useful devices. These products are created according to people’s needs. For example, the invention of the watch is a time when people can know what time is now, and make people have a stronger sense of time and plan to do things. Why are these GPS shields so popular?

GPS trackers have been invented and they have their own market. GPS trackers are a very important invention of the police and military. For the police, GPS trackers can help them easily track criminals. In order to create a thorough criminal gang and catch the criminal gang, it is very important for the safety of the police and the people. For the military, GPS trackers can accurately locate the enemy’s location and send information to us, which is an excellent tool for our military activities.

Although GPS trackers have such excellent functions, GPS trackers are mainly used to track and locate installed personnel. We can use this device and it will also be used by criminals. For some people’s crimes, it may threaten people’s lives and property. All things in the world based on the laws of nature are car GPS jammers invented by people, which specialize in GPS trackers. This kind of equipment is not allowed for private use in many countries, and it is worried that it will affect the police tracking signal criminal groups.

The use of GPS tracking equipment to track events is not rare, and it is very common in our daily lives, whether it is for individuals or cars. GPS trackers can be purchased online in many shops, and with the advancement of science and technology, its design is becoming more and more concealed, easy to hide and install, even if you walk by your side, you are likely to be installed. Therefore, more and more people can buy GPS signal jammers to ensure their safety and personal safety, which can not only be used effectively for GPS tracking devices, but also be vigilant, because you never know when you will install GPS Tracking equipment.

The invention of GPS jammers provides people with a layer of protection, not only for their own safety, but also for their cars. People are grateful for the invention of GPS signal jammer, which makes them no longer worry about being tracked by GPS trackers and posing a threat to their safety.

GPS jammers and GPS tracking devices are very important to the police and the military. Based on the principle of making them safer, many products are currently marketed and demanded by people, and people’s lives can be protected by layers. The advancement of technology and the invention of car GPS signal jammers have provided them with important protection measures.

To have a GPS shielding device to protect you, choosing a portable GPS signal jammer is your good choice.

Devices that can detect jammers are used by law enforcement

Humphreys is a University of Texas expert and is frequently consulted by law enforcement agencies and other government security experts. He said there may be other jammer incidents that have not been made public.
He said: “When I was questioned by the FBI, they often mentioned incidents of frequency jammer and even deception … but of course they did not reveal the details to me.”

Humphreys demonstrated how to use deception to use GPS for navigation to control a vehicle. In June 2012, he and several graduate students demonstrated the technology to Department of Homeland Security officials by commanding civilian drones; The following year, they had a larger run – a 213-foot superyacht – and tricked its GPS navigation system, causing the ship hundreds of meters to deviate from its course in the Mediterranean without issuing any vessel warnings.

Humphreys said these demonstrations require considerable effort and expense, and it is estimated that it took five years to develop “devices capable of simulating and then overwhelming real GPS signals.”

But last year, when Chinese technical experts showed the Defcon Hacking Conference how to use a $ 300 software radio to spoof a GPS, the situation changed dramatically.

Humphries said, “Now I have the ability to download what’s available online to a commercial RF card and build your own scooter.” “For those with little experience of RF work, it will only take a few hours.”

Humphries estimates that the result is that “since 2012, the difficulty of launching wave jammer attacks has decreased by about 100 times”.
Although interference “in the wild” is generally an annoying crime causing a brief interruption of the GPS or a fall of a cell phone tower when someone is nearby, the risk of cheating with inappropriate hands may be greater. tall.

As the head of NovAtel Soar said, “The runny-nosed kid in the bedroom can now be our worst nightmare.”
The police began to retaliate. Curry said, for example, that jammer detection equipment manufactured by Chronos Technology had been in use for about a year and “was starting to find a way to use it as standard.”

Prison security audit says mobile jammers are expensive

Given that an average of three cell phones are collected each day in state prisons, an internal prison security audit conducted by the state prison department found that the installation of the 4-G cell phone jammer and body scanners might not be of much help in suppressing harassment.

In addition to the estimated high cost and the frequent escalation of human interventions, authorities have also expressed concerns about the health of individuals and prisoners.

Police Director General Sinha said that even after investing heavily in complex technology, it was not a permanent solution. It costs around 1.25 crore and disrupts cell phone signals within a 30-meter radius, he said.

He said the assessment process was conducted after the higher courts in Punjab and Haryana ordered jammers installed in all prisons last year.
“As a pilot proposal to reduce the cost of human disruptors, we have identified 24 high priority areas in 14 prisons in which serious criminals are held. It is estimated that after spending 22 million rupees, we will only cover 10% of these prisons, leaving a large gray area, ”Sinha said.

Once approved by the secretary of the central cabinet (security) secretariat, it takes about nine months to purchase and install the jammer.

“As we explore cell phone jammer, technology upgrades accelerate 5-G. In this case, it will make these jammers unnecessary. Our assessment shows that the interference will affect people within two miles of the prison. However, mobile phone service providers are considering improving the signal for users living near prisons. In this case, we might have to spend more time indefinitely on the upgrade, which is a never-ending process. ”

The National Prison Service recovered 1,086 cell phones from various prisons in 2019. According to relevant officials, in January and February of this year, authorities only seized 580 cell phones.

“We recently launched a system where prisoners can use 10 different phone numbers to call for 10 minutes a day. We are designing more effective methods to monitor unauthorized use of cell phones in prisons,” the official said. .

The ADGP said that ensuring that the installation of the wave jammer does not lead to adverse effects on the health of prison staff is indeed a concern.

Sinha said the full body scanner costs around ₹ 3 crore and cannot detect the phone or anything hidden in the body cavity.

“Full body x-ray scanners are very effective at detecting any other object hidden in the phone, rectum or other body cavities. But there are no legal penalties in the country for the use of such. scanners in prisons, ”he added.

The threat posed by the terrorist drones

Most hobbyists think their drone is a great tool – much less dangerous than a hammer and much more fun.

But there are times when we wonder about the drone’s dark potential. What could it be doing in the wrong hands? However, from a sense of good citizenship, it is unlikely that most drone users would share these thoughts publicly.

Feel free to vent because the U.S. Army Association has voiced your worst fears.

A new report suggests that the increasing use of drones to pollinate plants shows that they can deliver chemical or biological warfare agents (CBW) alike. Additionally, software that allows multiple drones to swarm and coordinate is likely to encourage the spread of these toxins.

Pranks or fake murders?

Lt. Col. Claude A. Lambert, a strategic planner with the U.S. Army Materiel Command, points out some worrying incidents where drones could have wreaked havoc:

At a rally in 2013, a drone crashed harmlessly near Chancellor Angela Merkel
Authorities found a drone potentially contaminated with radioactive cesium on the roof of the Japanese Prime Minister’s office in 2015
I’ll add a newer one: A drone caused a seven-minute hiatus from a Chicago Cubs game last month when it landed on Wrigley Field.
Depending on your point of view, these are either funny japes or mock assassinations. Military must take the darkest view of human nature. Therefore, Lt. Col. Lambert is calling for a national US strategy to detect and identify drone threats. However, he doesn’t have any easy solutions.

“There is no such thing as a ‘magic bullet’ to counter a … threat,” he writes. “Not a single comprehensive material solution will completely eliminate the (drone) problem. Kinetic methods, signal hijacking, radio frequency interference and directed energy are areas that can be explored in order to defeat (drones) in a practical and inexpensive way. ”

He says in July 2019 the U.S. Marine Corps successfully deployed a new portable jammer to jam an Iranian drone in the Strait of Hormuz. But this was a military on alert in a conflict zone. Domestically, the FAA registers around 1,700,000 drones in the United States. Nobody knows how many are not registered. Lt. Col. Lambert believes the military and law enforcement must work closely with academia and industry to counter the threat posed by deadly drones.

Preventing the weapon from drones

He also wants the international community to stop trading chemicals that could arm drones.

Lieutenant Colonel Lambert points out another possible weakness in the drone shield. The U.S. military has minimized its chemical and biological training in recent wars because its opponents lacked these weapons.

“As a result, the joint force is now unprepared to face a chemical or biological warfare threat,” he writes.

“One thing is certain: anyone willing to develop or acquire a CBW agent and deliver it via a (drone) probably cannot be put off.”

How to make a signal blocking cellphone pocket?

For some at the National Republican Congress in Cleveland, the choice of protective accessory is an AR-15 rifle that is casually slung over the shoulder. For the Los Angeles-based artist and activist Tim Schwartz, it is a discreet pouch made of matt silver ripstop fabric that houses his cell phone.

This cell phone signal jammer blocks the signal that cell phones keep sending – a feature that Schwartz says is essential during an unpredictable, politically charged event like the Republican National Convention.

4g cell phone jammer

“I think it’s sensible that everyone should protect themselves when they get into a situation where they don’t know what’s going to happen,” says Schwartz. In particular, he states, “You can be easily followed by turning your phone on and off.” And if there is a disruption, the information could even be used retrospectively: “The government could request records and show that you were in this area when something went wrong.”

The Electronic Frontier Foundation, a non-profit organization dedicated to protecting civil liberties in the digital world, advises protesters that while their phones are powerful tools for documenting photos and videos, they also contain a wealth of personal information, including contacts, location and message history, emails and private credentials. “Our whole life is on our devices,” says Schwartz.

These high frequency blocking pockets, known as Faraday cages, are readily available to the powerful population that Schwartz calls the “techno elite.” Quartz reported on a $ 720 value of a cash transport and RF blocking bag, and President Barack Obama is traveling with a tent that serves that purpose.

For RNC protesters looking for a cheaper DIY option, Schwartz is holding “office hours” for protesters at the Spaces gallery in Cleveland to sew their own signal-blocking cellphone cases according to instructions from Berlin-based artist Aram Bartholl. Its meetings will take place today (July 19) and tomorrow from 1 p.m. to 4 p.m.

This is a protection that non-protesters could also consider, Schwartz says. “It’s like having long passwords,” he says. “It’s one of those things we should do, but we never get to it.”

Schwartz provided protesters with a copper taffeta fabric, a sewing machine and advice. He says his eighth grade sewing home economics training is appropriate for the job, and notes that the most important step is to make sure all of the edges of the bag are folded and secure.

Here are the directions from Aram Bartholl’s “Kill Your Phone” website. Materials are available on lessemf.com:

Cut 12 cm strips from your roll barrier fleece.
Make pieces of 50 x 12 cm, each for a bag. (i.e. you get 2 pieces of a 1 m long strip of rolls.)
Fold your 50 x 12 cm piece to 25 x 12 cm
Fold the long sides again, 1 cm each, and pin them in place with needles.
Sew two straight seams on the left and right.
Fold the opening at least 2 times! Find a paper clip or clip to close the pouch.
Done!
Schwartz previously developed a tool for victims of the Haiti earthquake to find their missing family members in 2010. He then “fell into the rabbit hole of digital privacy” and worked with the Center for Legal and Information Policy (CLIP) at Fordham Law School to investigate online privacy and reconcile it with security .

In recent years, Schwartz has conducted workshops on digital data protection such as “How to be a whistleblower” at schools like Cal Arts and UCLA, partly in collaboration with the web-based data protection movement Cryptoparty. For the remainder of the month, he will continue his work as an artist-in-residence at Spaces, where he is hosting events like a “dark web treasure hunt” to help people learn more about digital privacy.

Use of GPS jammers for personal use

You can easily order GPS signal jammer from the Internet, and you can protect privacy and prevent third-party tracking. These products are beneficial and should be purchased. For example, certain VIP roles can prevent illegal positioning by GPS trackers.

Of course, in North America and Europe, such devices are also needed to protect privacy. Because you don’t know when others will follow your vehicle. GPS trackers are easy to buy.

GPS jamming technology can also be used to manage drones. Professor Todd Humphreys and his team have used GPS deception technology to control an unmanned drone in Austin. They used a small helicopter to destroy the GPS system of the drone, and then provided the drone with the coordinates to reach the destination.

In positioning applications, we have a common problem: instead of trying to position the transmitter relative to ourselves, we try to position ourselves relative to a series of transmitters. Of course, we use the same technology: GPS is a good example of a TOA system.

The loss of commercial aircraft GPS functions will certainly lead to catastrophic air disasters, but Norwegian Intel believes that Russian GPS interference with Finland/Norway is neither the intention of the Russian government nor the intention of the Russian military.

Delhi government to install cell phone jammers in exam centers

It is common for jammers to be installed at investigation sites.

The AAP government has decided to install signal jammer to prevent high tech electronic equipment from being cheated on exams that are held for government agencies in Delhi. Stop being cheated during exams. The increased use of electronic devices in written tests has made the city government concerned about the possibility of incompetent candidates joining the government. “After the Delhi Subordinate Services Selection Board (DSSSB) successfully used the jammers in an auditor test a few months ago, they decided to use the device in their critical tests,” a government official told IANS.

The DSSSB was founded in 1996 and conducts written tests and interviews for middle and lower positions in the state government and in city authorities. A cell phone jammer is an instrument that prevents cell phones from receiving signals from base stations. When used, the jammer effectively disables cell phones. It transmits on the same radio frequencies as the mobile phone and interrupts communication between the phone and the base station of the mobile phone in the tower. “Nowadays students are using technology to pass exams which is the other side of technology. They remember ‘Munna Bhai MBBS’, don’t they,” added the official, referring to the Bollywood film in which the protagonist is featured – a local crook – is shown undergoing a medical examination with the help of a small earphone. “Applications were invited by various phone jammers service providers,” said one official.

According to the tender, the agency must ensure that a sufficient number of jammers are deployed and installed to block cellphone and blue tooth services in the exam center. Another requirement is that jammers, with or without a power supply, work without technical interference for the entire duration of the tests. There are various gadgets available in the market that can be customized for salwar kameez sets, sports bras, jackets, shirts, and regular buttons. In May, the Supreme Court ordered the center to install telephone jammers in exam centers to prevent paper leaks and other abuses. The guideline was created after an alleged fraud in the All India Pre-Medical Test (AIPMT). Many aspirants had SIM cards sewn to their shirts and had bluetooth devices. Over 350 calls were made to the various exam centers.

Example of installation of UAV countermeasure equipment by cultural relics protection unit

UAV “black flying” harm

There are blind spots in the supervision of drones in my country, and the large-scale use of drones brings hidden dangers to public safety. Drones that were originally used for legal purposes are increasingly being used for criminal purposes. The public has become increasingly aware of the harm that drones may cause. UAVs can smuggle drugs; UAVs can spy on privacy/technology; UAVs can affect civil aviation – close to collisions; UAVs may appear in sensitive areas, key locations, cultural heritage protection units and government facilities; UAVs may even Can shoot automatically…

Because the intrusion of drones has brought great harm to everyone’s lives, many units have begun to install drone countermeasures. Let’s take a look at this fixed drone counter independently developed by Texin Electronics. Control the efficiency of the equipment.

Can the communication signal be retained by using a jammer?

Many people do not understand the jammer, so using a jammer in an emergency causes the cell phone signal to drop and the outside world cannot be contacted.

Are you planning to use a mobile phone wifi jammer in your building or place of business? If so, you’re probably curious about how they actually work – and what effect they have on cell phones.

desktop wifi signal jammers

When using a jammer, a low power radio signal is broadcast. This signal is able to cut off the communication between the cell phone and its cell base stations. When this happens, all mobile phones in the affected area display “No service” and incoming calls are blocked. To the caller, it just looks like the cell phone is turned off.

Although jamming of mobile phones prevents them from receiving service, some predefined areas are not blocked. By default, these frequency zones include:

* EMS bands

* Fire bands

* Police tapes

* Medical services pager bands

Therefore, when using active jamming, you don’t have to worry about putting yourself in danger or putting someone else in danger. Police, fire and EMS radio users as well as pager users can still communicate, but your clients, clients or students will not be disturbed by non-urgent phone chatting, providing a calm environment.

Once the jammer is turned off, the phones will automatically re-establish communication with the cellular base stations – and those affected by the jammer will be able to receive cellular service again.

It should be noted that using a jammer does not damage the phones in any way. It should also be noted that the same situations apply to any model of GPS jammer that we also offer.
