Question: Are portable radio frequency jammers as effective as bomb jammers?

Answer: It depends on several factors. Many manufacturers claim how their portable radio frequency jammers will use their interference methods and the interference methods they use. Although we did not explain in detail how portable radio frequency jammers such as portable jammers participate in countering improvised explosive devices to the public, we can disclose open source information.

These factors are the interference methods used by portable radio frequency jammers; the spatial factors of the radio transmitter related to the radio receiver and the characteristics of the knock signal related to the specific frequency used by the RCIED.

GPS jammers are becoming more and more popular

As GPS systems become more and more popular, GPS signal jammers have become necessary for us. You may want to know what GPS jammers are and what potential applications they have. In order to explain the GPS jammer, we first need to know how the GPS system works. Global Positioning System—GPS for short, is a system used by many people, companies and military for navigation purposes. The GPS system uses a series of satellites that emit radio signals. Such signals reach the electronic GPS receiver to determine the position by triangulating the shape. GPS can be used for personal portable electronic devices, vehicle navigation and positioning systems, and can also be used for small GPS tracking devices. The position of a person can be found by triangulation, which is a method of measuring three separate points to calculate the position. In the GPS system of the vehicle, the position of the car is measured by three satellites orbiting the earth. GPS can accurately transmit location information to the receiver through triangulation.

gps wifi cell phone jammers

Let us now look at GPS signals, which are radio signals occupying specific frequencies. GPS actually has two main frequencies, one is for public and non-military use, and the other is only for the US military. Since GPS is nothing more than weak radio waves, although technical equipment and expertise are required for this purpose, GPS jammers can be used to block or distort these waves.

GPS jammers were originally created by the government for military organizations and spy agencies. Some themes can be combined with cell phone jammers (also called cell phone jammers and wifi jammers). Uses include messing up the enemy at exact locations, or making enemy GPS guided missiles or bombs fall in these places.

Recently, civilians have sought these devices to ensure their privacy in a world increasingly tracked by GPS. However, most civilians do not have the technical ability to create their own devices because it is much more complicated than blocking radio signals through basic radio interference.

Prison installs Jammers to prevent illegal trade

With great concern and for many reasons, I support the legalized control of Cell Phone Jammers for use within correctional institutes.

A cell phone in a prisoner’s possession allows him to contact outside partners in the crime to coordinate evacuation plans, creating life-threatening situations for the guards and the public surrounding the institution. More often, reports from correctional facilities overwhelmingly indicate that hidden cell phones have been used to harass victims of their crimes, or an inmate repeatedly intimidates his victim in an effort to persuade the victim to retract his charges or change his mind. history. the testimony.

Many inmates continue to organize their illicit drug trafficking within the prison walls. A cell phone is an essential way for the inmate to keep the drug organization running and tightly controlled. By communicating with visitors prior to their arrival, prisoners can arrange for a transfer of drugs and drug paraphernalia, allowing them to perpetuate the same illegal habit that brought them into custody. Frequently, the family experiences harassment from their incarcerated parent, demanding bail when the family recognizes that the parent is better served and remains in detention.

A significant concern is a detainee’s ability to contact witnesses prior to an impending hearing, trial or appeal. By matching alibis or correcting conflicts in testimony, an accused can achieve a reduction or a complete dismissal of the charges. The most frightening concern that correctional institutes claim are undetected cell phones used by inmates to warn other inmates ahead of surprise searches that could confiscate cell phones, knives, drugs, syringes and other contraband . This contraband can pose a threat to the lives of correctional officers and medical personnel working in one of the most hostile and dangerous workplaces.

In summary, prisons in accordance with Cellular cell phone jammer is imperative, with a cell phone jammer you can prevent prisoners from using cell phones for illegal transactions or contact with the outside world, endangering the cell phone. public order and cause irreversible injury. Our cell phone jammer is very easy to use. Just turn on the switch, and within 5 seconds, it will enter the state of no network within 40 meters. The phone will display the no service status. Will not affect the use of other equipment.

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.

Can the test signal blocker block all communication signals?

Can the test signal jammer shield all communication signals? Speaking of which, many people are unfamiliar with the test signal jammer device. In fact, it has been widely used in the college entrance examination examination room. In the college entrance examination last year, many examination rooms installed this kind of equipment. The response has been very good, and it has been proven to have a good effect on preventing electronic signal cheating. Starting this year, it has been vigorously promoted so that more examination rooms can also install shields.

Nowadays, the emergence of shielding device has solved many hidden dangers of disrupting the order in the examination room, so that candidates can take the exam in a fair environment. The principle of this kind of test signal jammer is actually to isolate the electronic signal to make the communication signal of the mobile phone fail, which can prevent the phenomenon of using mobile phones to cheat. Not only that, it also has a good shielding effect for the WIFI2.4G signal. Say that the effective range is within a radius of 0 to 30 meters, generally a low-power test signal jammer is enough to cover an entire classroom, which meets the needs of the test room for shielding signals, and because the endurance of this equipment is generally three Although the heat dissipation is poor, it also leads to a particularly high price/performance ratio. It is especially suitable for schools to purchase signal shielding for examination rooms. Many customers have troubles about the purchase of test signal jammers. At this time, you can contact greatjammer to inquire about the price of test signal jammers. It is a manufacturer with many years of high-quality and rich experience in the development of jammers. It has one The first-class technical team provides technical support for product quality, which is deeply favored and selected by customers.

The prison service has requested the installation of a signal jammer

Due to concerns about the ineffective jammers installed in the Rajasthan Central Prison and the use of cell phones by inmates, the State Prison Service asked the Home Office to transfer the total income of the three prisons from ‘worth Rs 2012 for best results.

Not only is the government struggling to restrict phone use, prison security is also affected. The High Court also takes these matters seriously. The prison official added in a letter to the government: “In order to prevent the prisoners from using the telephone and to better interfere, we ask you to approve the transfer of these 57 jammers to the two central prisons of Bikaner and Bharatpur. And “Ajmer”.

The prison department has requested a budget of Rs 7,200,100 for the transfer of the jammer, Rs. 1.12 million for the new tower, and Rs. 188 crore for the annual maintenance of the equipment.

As we all know, mobile phone signal jammers are very common. People will choose to buy mobile phone signal jammers to maintain their privacy and protect their independent space. Where will the jammers be used?

armband mobile gps jamming

Cell phone jammer is mainly used in various places where cell phone use is prohibited, such as various inspection rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals , governments, finances, prisons, public security and military might.

It is understandable that the WiFi cell phone signal jammers in the market can limit cell phone signals that are 500 meters from the transmitting station and have a radius of> 20 meters. The shielding radius is adjustable, it only protects the cellphone signal without affecting other electronic devices. Save energy, the power is 20W-480w.

The mobile phone is in a certain frequency range when it is operating. The mobile phone and the base station are connected by radio waves, and the data and sound transmission is supplemented by a certain baud rate and modulation method. Taking this communication principle into account, the mobile phone jammer will sweep the frequency from the low to the top of the front channel at a certain speed during the working process. The mobile phone seems to search the network, there is no signal, no service system and other phenomena.
The signal jammer is very convenient and practical, you don’t have to worry about whether it will be difficult to use.

US military develops new electronic jammer

An overview of US federal government policy on activities where jammers can cause loss of GPS signal:
Sometimes the US federal government has to perform GPS tests, training activities, and exercises involving jamming of GPS receivers. These events are the subject of long-term coordination by the Federal Aviation Administration (FAA), United States Coast Guard (USCG), Department of Defense (DoD) and other government agencies.
The Army Threat System Management Office (TSMO) team visited the National Training Center on December 2 to demonstrate the newly developed electronic jammer at the Redstone East Arsenal office in Alabama.

Curtis Leslie, TSMO electronics engineer, said the team briefly introduced senior leaders at the National Training Center to how to program a small purchase direct injection jammer based on prompts to simulate radio signals used for detection and electronic communication in battlefield training scenarios. interference.

Leslie said, “We can put them on Hummers, Hummers and other 5 ton tactical vehicles.” “Our injection jammers can be used to replace outside interference.”

The interference box is installed between the antenna and the radio transceiver. When prompted by a simple line-of-sight signal sent remotely by the observer-controller-trainer, it can be programmed to digitally generate various interference signals.

Leslie said typical jamming transmitters broadcast live on “public” radio waves require approval from the military, Federal Communications Commission, or Federal Aviation Administration, which generally limits interference to late nights and early in the morning. He said that while the concept of jammer injection is not new, recent technological advancements have made wifi jammer smaller and require less power, making them ideal for military training centers, as in training centers, the radio spectrum can be very crowded and problematic.
The National Training Center demonstration is part of the Army’s space training strategy, which will provide cutting-edge technology developed by TSMO for the combatant training community.

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.

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.”

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.
