WiFi and Bluetooth are wireless technologies that support the 2.4 g frequency band to exchange data over short distances on fixed and mobile devices. From this perspective, Wi-Fi or Bluetooth connection requires users to use it to send information and documents, which is very convenient. Now, users can easily use wireless network access, which provides users with many conveniences.

Wireless networks also have many shortcomings. Criminals can easily obtain passwords and important personal information from wireless networks. Once other people know the password, we face a great risk. The most obvious aspect is that your privacy may be stolen by hackers, including various account numbers and passwords. Wifi jammer can keep your information confidential and help you rule out information risks.

Anti-UAV Technology Development Prospect and Impact Analysis

With the rapid development of military and civilian UAV technology, especially the successful development of reconnaissance/attack integrated UAV, the development of the “swarm” attack mode, the efficiency and cost-effectiveness of using traditional missiles and shells against UAVs The problem is getting more and more prominent. At present, all countries are stepping up the launch of strategies for UAV defense and promoting the rapid development of anti-UAV technology and equipment. Compared with missiles, the use of electromagnetic interference and lasers to counter unmanned aerial vehicles has the advantages of speed, flexibility, and high cost-effectiveness, and has attracted the attention of various countries. The successful development and testing of a batch of anti-UAV equipment in the United States and Europe has provided efficient and low-cost measures to defend against possible future drone threats.

Drone Jammer Interception System

In recent years, unmanned aerial vehicle technology has spread rapidly and widely, and a large number of remote-controlled helicopters and multi-rotor aircraft that are easy to control have appeared. Unexpected incidents related to unmanned aerial vehicles have frequently occurred, posing challenges to security and public order management. In the future, drone jammer technology will play an important role in the security field. In addition, the anti-UAV system is an emerging equipment that will help promote the development of technologies in the fields of microsystems, electromagnetic spectrum, and directed energy.

How to prevent eavesdropping in the car?

The ever-changing technology also makes it easier to expose people’s privacy to the public’s vision. Recently, a small gsm eavesdropping on the market is very popular. It is understood that many buyers install this type of eavesdropping device in the car. Many people also responded to our colleagues that they were afraid that their private conversations would be eavesdropped. This kind of eavesdropping equipment can be installed in a very hidden place and is not easy to be found. Even many professional anti-eavesdropping equipment cannot be detected. What is it? The reason?

It is understood that this gsm bug is only the size of a coin. It can be placed in the car, or it can be attached to a certain place on the car using a magnetic device. What is more, it can be placed in a place that is difficult for people to detect (such as the instrument In the built-in electrical equipment), the driver’s conversation information can be recorded unconsciously. Of course, the eavesdropper may also receive a car battery or a large-capacity battery for continuous GSM tracker. On the other hand, this makes the threat more persistent and keeps the privacy of the eavesdropped being stolen. This GSM bug can be placed in a hidden place in the office or at home, such as under the desk or built-in in household electronic devices such as alarm clocks, TVs, and chargers. It is very hidden. The power supply under the table may be cut off and may be unintentionally discovered, but it is not only difficult to be detected when it is built into an electrical appliance, but it can also be directly used for indefinite long-term work. Illegal tracking of vehicles, eavesdropping of conversations in vehicles, and eavesdropping of private households are illegal acts and a great threat to personal privacy, and should be paid attention to.

Why is this kind of eavesdropper so difficult to detect? Because it is an analog mobile phone signal, it is mixed in many mobile phone signals, and it is not easy to detect. Even if some professional detection equipment is not operated by someone who is very familiar with wireless signals, it may be No results are found. When the eavesdropper dials the phone card number in the eavesdropper in a remote place, the eavesdropper starts to work, and the surrounding sounds are transmitted to the eavesdropper through the mobile phone signal. Tracking and positioning. It is always threatening people’s normal work and life.

For such a very concealed eavesdropping device, should it be located and swept away? The following is a practical anti-eavesdropping GSM jammer recommended by the security experts of Shenzhou Mingda, because the working principle of gsm eavesdropping device is similar to that of mobile phones, so The mobile phone detector can well detect the source of such gsm bugs, so as to find the eavesdropping equipment, remove hidden dangers, and completely eliminate the threat of eavesdropping and tracking. It can find hidden mobile phones in the environment (turn on or off, even without batteries). It is a short-range mobile phone scanner, which is different from traditional metal detectors: it can detect the common material of all mobile phones, not just for metal, which can reduce false alarms for other metal materials, such as watches , Keys, coins, belt buckles, etc. This anti-eavesdropping detector is very easy to use. It can quickly complete environmental security detection and find hidden mobile phones in time (even if they are covered by metal or packages can be detected). The device is easy to operate, with LCD interface display, and 9V battery power supply, which is convenient to carry. It can help car owners to detect eavesdropping on their cars.

Install a network jammer near the meeting room

The National Congress and the Nationalist Congress Party (NCP) require that frequency jammer be installed outside the locker rooms, and EVM and VVPAT are kept in the locker rooms to eliminate any possibility of tampering.

The conference also called for a 50% EVM verification against VVPAT documents to increase transparency. The results of the poll will be announced on October 24.

“Much of society thinks EVM can be impaired, which poses a threat to democracy. To ensure free and fair elections, network jammers should be installed in and around solid rooms before and during the counting process. This will eliminate the possibility of tampering via mobile towers, Wi-Fi networks and other wireless networks. We also ask you to leave candidates the freedom to choose which EVM to test against VVPAT, ”he stressed in the letter. NCP also made similar requirements.

Congress is also asking organizations that have announced their withdrawal from public opinion polls to divide their booths and constituencies. “Citizens are not satisfied with the way to withdraw from the ballot box. We suspect that withdrawing from the ballot box is an activity that helps people to accept results beneficial to the ruling party. The institutions that conduct the polls should explain the results. survey results in more detail to maintain transparency. ”

At the same time, the Election Commission took legal action against a person who committed a fault on an EVM at Navalewadi in Katav, Satara. Workers in a political party complained that even after pressing other buttons, they still voted for the BJP. However, the European Community clarified that there was no difference.

“The complainant refused to file a written complaint. He then spoke about the machine malfunction on the TV channel. In the mock vote conducted before the actual vote, the machines were inspected in front of polling officers from all political parties. We are now taking action against voters, including installing phone jammers. Said Dilip Sind, Chief Electoral Officer of Maharashtra.

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.”

5G mobile phone signal jammer parameters

5G signaling is the hottest topic of the year, and the construction of 5G base stations across China has begun to implement 5G signal coverage. How convenient is it to use 5G signals? On the morning of May 10th, Hunan 5g Digital Industry Association and 5g + started the ceremony at Changsha Meishif International Cultural Arts Center, started the ceremony, Hunan Mobile and Xiang River, Hunan University, Xiang River Hospital, Banda Environment, Cool Wow Banda Partners have signed strategic agreements such as the establishment of a general 5g digital industry alliance to speed up the development of 5g application innovation. On the experience site, Revo, general manager of Hunan Mobile Changsha Branch, also passed the first 5G video call with Changsha City’s Tianxin District Committee standing member and Changsha City’s deputy director, State Shijun. .. We can think of how convenient 5G will bring to people.

As a new information technology infrastructure capable of providing at least 10 times the peak rate of 4g, transmission delays of millisecond, and billions of levels of connectivity, 5G is an automated driving, big health medicine, industrial internet, city of wisdom, Internet infrastructure for building things, high-definition video application scenarios to drive the Internet, big data fusion, artificial intelligence, and the depth of the real economy are critical to supporting high-quality development. is. It also brings about the rapid development of science and technology.

“3G, 4G, probably low and long wavelengths, at which high frequencies can resonate with some of the vibrational frequencies of water molecules and oxygen.” After the advent of 5G, future technological advances in 5G Not only do we need to enjoy the convenience and convenience, but we also need to pay attention to the effects of electromagnetic waves on the human body.

China Mobile and China Unicom have issued a license to use mid-low frequency test frequencies in 5G systems. Among them, China Telecom and China Unicom have obtained licenses for test frequencies in the 3500MHz band, and China Mobile has obtained licenses for test frequencies in the 2600MHz and 4900MHz bands. Therefore, it is safe to use 5g jammer within the range. China Unicom and China Tele have secured a more international mainstream spectrum, but the story of China Mobile is much more complicated. In terms of subdivision, China Mobile has acquired 5G test frequency resources in the bands 2515mhz-2675mhz and 4800mhz-4900mhz. Of these, 2515-2575mhz, 2635-2675mhz, and 48800-4900mhz bands have been newly added, and 2575 bands have been added. -2635mhz prioritized China Mobile’s existing td-lte (4G) frequency.

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.

GPS blocker

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.
