There are no jammers in the prison and criminals use cell phones to blackmail

Taking advantage of the lack of a jammer, the prisoners at Mandoli appear to be doing free blackmail, filing complaints, making videos and sharing them with contacts in the glory of the unwavering 4G.

Mandoli Prison in Delhi (which has housed more than 3,000 inmates) operates without interference from mobile phone signals, as the prison administration is still waiting for 4G interference. Administrators at Mandoli Prison (opened to prisoners in 2016 to ease congestion at Tihar Prison in Delhi) confirmed that they had not installed a single jammer.

The device is used to block the cell phone signal, even if the prisoner manages to smuggle the cell phone in, it will also prevent the prisoner from using the phone in the prison.

Inmates are prohibited from carrying or using cell phones in Indian prisons.
Taking advantage of the absence of distractors, the prisoners of Mandori appear to do free extortion, file complaints, make videos, and share them with contacts in the glory of unwavering 4G.

In the past two months, Delhi police have claimed to have destroyed two extortionists led by prisoners at the Mandoli prison complex.
On Thursday last week, three prisoners were reportedly arrested (in this case formally arrested from inside the prison) and demanded 50,000 rupees for a man from Gita settlement.

Two days earlier, the city police task force (counterterrorism force) claimed to have arrested two men who had been sentenced to prison in Mandoli and killed two men, thus avoiding the murder. The police then said they intercepted the phone call from Chandban (aka Amman Yadav) who lived in Mandoli prison to his accomplices Barkishan and Mohamed Atik to eliminate the two who had not paid him protection money. people.

hidden cell jammers

A senior Home Office official said the cell phone jammer was only recently approved by the government. “We have moved for their installation and preliminary work is underway. It takes time to get permission to use jammers and install devices with the latest technology. But once installed, these devices will be the best. and will return all phones. It becomes unnecessary in prison. ”

A fortnight ago, a video of a gang leader in Uttar Pradesh showed the man recording a video on his cell phone while cooking in a Mandori prison cell, which has become popular on the media. social networks.

Prison officials said that although phone jammers may be installed in the new prison, the prison director has asked them to carry out strict inspections on a daily basis.

“Senior officials have ordered us to carry out strict security checks and warned us that we should take action if the cell phone is smuggled inside.” In the case of a small number of prisoners using cell phones, an investigative procedure has been ordered. We were warned that we would take action. Act strictly so that this does not happen in the future. “

Drones and jammers are the biggest threat to airports

The Ministry of Civil Aviation has proposed a draft regulation that allows the use of drones for any purpose, but with certain restrictions.

While the Ministry of Civil Aviation has legalized the use of drones, government agencies are testing jammers that can disable drones that can pose a threat to safety.

A device designed to block drone communication systems is currently being tested at Delhi airport. Helicopters consisting of the Central Industrial Security Force (CISF) and the National Security Guard will also be dispatched as back-up personnel for emergency situations.

“Although the proposed guidelines for civil aviation state that the five kilometers around the airport is an uninhabited area, regulatory violations cannot be ruled out. Drones are typically managed by operators through a system of remote communication. The equipment we are testing will block the communication system., After that, the operator will no longer be able to control the drone.

Jammers Portable Handheld

The Home Office (MHA) plans to enact legislation to prevent the misuse of drones, especially near airports. Although airport security forces have been advised that drones are considered a potential security threat, no guidance has been issued on how to react when such aircraft are sighted nearby.

“Right now, drones are the biggest threat to airport security, with the exception of wave jammers. They are frequently observed and – currently there is no provision for shooting down flying objects. The CISF provides security, but has yet to decide who will deal with air threats. The Aviation Ministry will oversee the drone actions, but MHA must call for safety. ”

The source said MHA will issue a notice applicable to airports across the country.

The Ministry of Civil Aviation has proposed a draft regulation that allows the use of drones for any purpose, but with certain restrictions. Asked about safety, Aviation Minister RN Choubey said technology is being developed to neutralize rogue drones.

The ministry designated airports and international borders as unpopulated areas and stipulated that their use for commercial purposes requires special permits from aviation regulators. However, government agencies will not be bound by these guidelines.

The center invited the public to make suggestions within 30 days, then will make the necessary changes by December 31 to legalize the use of drones, and use drone jammer to prevent them if necessary.

GPS jammers keep others from knowing your location

The competition with the tablet development industry is very attractive. Since Apple’s famous iPad changed the world of computing, users like IBM wanted to change it in 1981 and get a handheld entertainment device in their hands as soon as possible.

Artificially since the last month of 2011, Apple iPad tablets have been a steamroller among the competitors. According to Apple CEO Tim Cook, their iPad owns 75% of all tablet sales in the United States. According to reviewers and customers, the biggest headache for Apple’s rivals is that no company has developed a tablet that matches the quality of the iPad. When talking about tablets, Apple’s iOS Android is an easy hit.

But now you can ask: how is this information related to GPS tracking? Frankly, tablet competition can change the way these GPS tracking systems work. Take, for example, Asus Transformer. Consistent with some reviewers, this Android-based tablet computer is the iPad’s strongest competitor, with the exception of the Samsung Galaxy Tab model. Asus has developed a great product with a well-integrated keyboard that makes it easy to turn this tablet into a nice netbook.

4g cell phone jammer

Unlike the iPad, and like many mobile phones, the Asus Transformer GPS technology inside the GPS device makes it surprisingly accurate and easy to track your location. But there is a problem. It doesn’t seem to work very well. Asus mentioned customer complaints about embedded GPS in tablets. This can be a bit slow and there is an embarrassing location delay.

So what is the solution? Along the Asus Germany Facebook page, we have developed an update to get GPS satellite signals using the tab Wi-Fi connection. So far, using Wi-Fi to completely replace GPS satellite signals sounds wrong. Wi-Fi signals are not so common all over the world, but signals from GPS satellites can be sent all over the world. Emerging technologies can eventually eliminate this question.

Of course, if you’re very concerned about privacy protection, you can choose the right GPS jammer and simply block the surrounding radio quickly to hide your location.

U.S. Army tests could not stop the new GPS last fall

Last fall, after Russia was suspected of jamming GPS signals in Europe and elsewhere, the U.S. Army will test an anti-jamming GPS to solve the defense breakthrough problem.

GPS jammer can also pose a major threat to the United States and allied forces, and everything from troop movement to guided missile and UAV guidance depends on the system. Last fall, the United States and NATO allies launched a large-scale joint exercise called Trident Juncture in Norway to test the joint preparations and training of a large multinational alliance. During the exercise, the military noticed that GPS signals interfered with signals attributed to Russia by Finnish and Norwegian officials. In April 2018, US officials stated that the Russian military had blocked the GPS system of UAVs used in Syria.

Members of the German Second Cavalry Regiment will be equipped in the fall. According to reports, the Army is considering developing a new generation of inertial navigation system that can be used as a backup system.

At the C4ISERnet conference in Arlington last week, Colonel Nickolas Kioutas, project manager for Army procurement developer Positioning, Navigation and Timing (PNT), said that it’s important to deliver equipment to troops quickly, and the Army is working hard to roll out the Equipment used in the iterative process. Breaking the defense points out that by putting the system in the hands of units like the Second Cavalry, the Army can quickly evaluate technology and make improvements if necessary-without spending years developing and testing equipment that turns out to be the wrong one.

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.”

Jammer-mart’s mobile phone signal jammer is recognized by consumers

Many friends who use mobile phones have this kind of distress, that is, the signal of the mobile phone often has problems. Especially friends whose home is in the country, can’t chat online all day long. But after some friends used Saiyue Communication’s cell phone jammer, this problem was completely solved.

The future market trend of the shielding device

The State Security Bureau, in cooperation with the Radio Management Committee of the Ministry of Information Industry, Northern Jiaotong University and other institutions, formulated the first industry standard, “Technical Requirements and Test Methods for Mobile Communication Jammers for Security Conferences”. With the guidelines relaxed, experts said the market potential of shielding devices is huge and the industry’s scope for development is extremely wide. At present, the global cell phone ownership has reached 2 billion. It is estimated that the demand for shielding devices is 1% of the total number of cell phones. That is, for every 100 mobile phone users, there is one shielding device user. This user can be It is a safe place, a secret place, a quiet place or a public place or a person.

The shielding system is not only used in high-level places such as arsenals, political parties, governments and military, public safety, finance and trade secrets, but it can also be used in places closely related to people’s lives. Experts believe that based on the latest usage analysis, the cell phone signal jammer market size could reach tens of billions of yuan.

The rapid development of modern communication technologies requires that companies of technological security keep pace with the times and continuously develop and strengthen their own strengths in order to meet the diverse challenges. The widespread popularity of cellular phones not only brings convenience to people, but also poses new problems for the security and confidentiality of communication. Eavesdropping, leaks, exam room fraud, medical accidents and gas station explosions occur endlessly and accelerate the shielding of cell phone signals. Promotion and use. It is mainly used in exam rooms, prisons, gas stations, cell phone bombing prevention, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor reform teams, conference rooms, theaters, churches, libraries, school dormitories, etc. for security and confidential occasions ( confidential offices, negotiation rooms, mobile vehicles, mobile politicians and dignitaries of companies) etc. as well as cell phone signal jammers are becoming increasingly important in social life.

Depending on the location, Jammer shop has designed and manufactured different kinds of jammers, designed and shielded different places, fully exploited the product performance, and greatly improved the effect of the jammer. It beats the crowd with its excellent performance. And received unanimous praise from the industry!

Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. The jammer scans from the lower frequency of the forward channel to the upper end at a certain speed during operation. This scanning speed can lead to garbled interference with the message signal received by the mobile phone. The mobile phone cannot recognize the normal data sent from the base station, so the mobile phone cannot connect with the base station and achieve the purpose of shielding the mobile phone signal. The mobile phone seems to be searching the network, no signal, no service system, etc.

Explosion proof of jamming device at gas station

In many countries, cell phone signal blockers were suitable for stopping calls at gas stations. Purchasing a modern and fashionable cell phone signal blocking kit is the latest and most wise advice for cell phone users and service station personnel.

The use of mobile phones is a danger of explosion at gas stations. Turn off your cell phone while filling the car. There are usually warnings about banning mobile phones at gas stations.

To stop the sparks, our stones have produced many sabotage products for your picking. Some people, especially teens, are unaware of hidden threats and easily forget warnings when at gas stations, so they easily fall into their cell phones for these reasons.

Now it is your mission to buy better cell phone signal blockers to avoid the tragedy. So what do you do? Get it now.

Cheap GPS jammers pose a major threat to drones

Jammers that can be bought for as little as $ 50 threaten commercial drones, but options exist.

With the rotors buzzing and the airframes racing through the air, drones can be very dangerous if flights don’t go as planned. Much has been gnawed about the FAA’s measured approach to implementing commercial drone guidelines, but the fact is there are real dangers, even from bad actors using inexpensive GPS jammer.

phone signal jammer

GPS signal jamming technology is evolving, decreasing in size and cost. These days jammers can be bought online for as little as $ 50. Jamming has long been a threat to military assets and is becoming a commercial problem today as commercial drone shipments become a reality and attacks become ubiquitous around the world. This threat now affects trade, law enforcement, and defense drones on critical missions.

During a choreographed light show in Hong Kong in 2018, 46 drones fell from the sky due to a jamming device. The resulting property damage and loss of hardware is estimated to cost an estimated HK $ 1 million. Almost all drones have security protocols that can be used to send them home or to a safe landing site in the event of a disruption. However, these functions were found to be ineffective at the Hong Kong show.

“These are professional-grade drones already built with technology that will guide them back to the launch site,” Anthony Lau Chun-hon, director of the events committee, told the South China Morning Post. “But the signals were so strong that many of them just fell out of thin air.”

Drones and their services are decidedly dependent on GPS signals. Although the drone may have backup methods (INS / OPS), GPS references are still required for positioning, navigation and stabilization. GPS attacks are therefore the easiest way to shut down a drone and potentially cause harm to life and property.

The good news is that solutions for drones are arriving with commercial quality and coming straight from the defense sector. One comes from a company called infiniDome, which makes a device called a GPSdome that is built into a drone’s GNSS receivers and uses a unique interference filter system that combines the patterns of two omnidirectional antennas. GPSdome analyzes the interference signal in real time and feeds its properties into infiniDome’s proprietary algorithm to filter and reject attacking RF interference, so that the UAS continues to rely on GPS signals during a jamming attack. If an interference signal is detected, the GPSdome notifies the operator of possible signal interference.

Easy Aerial, a leading provider of autonomous, drone-based surveillance solutions for commercial, government and defense applications, recently added GPSdome to its range of autonomous unmanned aerial systems for military use.

“We chose GPSdome because it was a proven solution that was a perfect fit for the various missions our customers routinely fly in some of the most inhospitable and hostile environments in the world,” said Ido Gur, Co-Founder and CEO of Easy Aerial. “While our systems have multiple redundancies on board, GPS signals for maintaining position, navigation and timing accuracy are critical to ensure uninterrupted operation.”

This type of lightweight, small form factor, low power shielding technology is a critical step towards widespread adoption of commercial drones. Other companies like Sepentrio also take GPS interference in drone applications with integrated sensor solutions seriously.

It is certain that the problem of GPS interference and spoofing will receive more attention in the coming days. Fortunately, developers seem to be beginning to see tools that they can use to counter the growing threat.

Can the mobile phone signal jammer interfere with the base station’s signal?

Cell phone jammers are familiar to everyone, but everyone who has taken a large-scale exam has seen them and put them at the entrance of the exam room. This is not a malicious blocking signal. On the contrary, this is to maintain fairness and provide a fair environment for candidates. However, most of the time, some people doubt whether it will affect the signal radiation of the base station, so that there is no signal in an area.

With the progress of society and the development of high technology, people’s standards are getting higher and higher. Nowadays, mobile phones have become a habit of adults and children. For elementary and middle school students, it is more important to influence what they say. Playing with mobile phones for a long time may affect their eyesight, and more seriously, neglect their studies.

Since the advent of cell phone signal jammer, they have been trusted by examination rooms, schools, prisons and other units. In fact, mobile phone signal jammers are no longer a new thing abroad, and have begun to be sold in the domestic market in recent years. The cell phone signal blocker only interferes with lower cell phone signals, so it will not affect mobile base stations and other electronic devices. Now many elementary and middle school students are holding mobile phones one by one, some are addicted to games, some are addicted to novels, etc. It is even more dangerous for school exams. Baidu has all the answers. If everyone used their mobile phones to plagiarize during the exam, it would violate the purpose and significance of the exam!

Desktop high-power electronic jammer

In the face of mobile phone signal shielding, we should treat it rationally and scientifically. The working principle of the mobile phone signal blocker is to send out a specific signal to wake up, block or interfere with the signal between the mobile phone and the base station, so that the mobile phone has no signal or cannot find the network service, and the mobile phone will send and receive text messages. Unable to recognize the original text message.

In fact, signal jammers generally do not affect the signal of the base station, so there is no need to worry, and no one will consider interfering with other people’s signals.

The mobile phone jammer scans from the low end of the forward channel to the high end at a certain speed during the working process. This scanning speed can cause garbled interference in the message signal received by the mobile phone, causing the mobile phone to fail to detect the normal microwave signal data sent from the base station. In a certain range, the mobile phone cannot be connected to the base station, and the mobile phone appears as a search network, no signal, no service system, etc., and thus cannot be used. The purpose of disabling the mobile phone is achieved. Its operating frequency is: 869~94MHz; 825~ 960MHz; 1805~1880MHz and 1900~l990MHz, etc. The operating frequency bands are CDMA800, GSM900, DCS1800, PCS1900. When the mobile phone leaves the range of the jammer, it can be fully restored to normal use. The electrical signal emitted by the mobile phone jammer is undoubtedly an electromagnetic signal, but this kind of jammer will never have any equipment to communicate with it, and it will never form a sudden change signal. In other words, this signal will always be in a relatively static state. , It will not interfere with other electrical equipment, and it is harmless to the human body.
