Recently, a video of a Chinese prisoner being beaten in Phnom Penh Bai Soe Prison in Cambodia was widely circulated on social media, which aroused great public concern and the intervention of the General Department of Prisons of the Ministry of Interior. The incident further revealed the management loopholes and safety hazards in the prison, and prompted relevant departments to take measures to strengthen prison management, especially strict control of mobile phone use.
According to a statement from the General Department of Prisons, the incident occurred between 9 and 10 am on April 5 in Cell No. 9 of Building C of Phnom Penh Bai Soe Prison. The victim was a 52-year-old Chinese prisoner named Li, who was sentenced to 12 years in prison for drug trafficking. The two Cambodian prisoners involved, one 35 years old, was sentenced to two years in prison for drug trafficking; the other 36 years old, was sentenced to 17 years in prison for drug trafficking and murder.
According to the investigation results of the General Department of Prisons, the cause of the incident was that a Cambodian man who was sentenced to prison for murder felt insulted and slapped Li on the head several times in anger, and then another Cambodian man also participated in beating Li. One day after the incident, the two Cambodian men involved apologized to Li. Despite this, Li still asked to be transferred to another cell to avoid being attacked again. https://www.silencejammer.com...-cell-phone-blocker
The prison punished the two Cambodian men involved, including prohibiting their families from visiting or sending items within 20 days. In addition, the General Administration of Prisons also emphasized the prohibition of using mobile phones in prisons, believing that the video shooting and circulation of the fight was deliberately planned by someone to attack relevant departments. To this end, the prison said it would further strictly control the use of mobile phones in prisons to prevent similar incidents from happening again.
This incident exposed some problems in prison management. First, the violent conflict between prisoners showed the prison's shortcomings in security. Although the prison claimed that no one was injured in the incident, the victim Li and his family still expressed concerns about his personal safety in prison. The prison said in a statement that it had asked Li, and Li said that he was not threatened with further persecution. However, this cannot completely eliminate the outside world's doubts about the security management in the prison.
U.S. middle schools ban students from using mobile phones for one year. These ar
Jammer B. | 18.06.2024 0 0
Maple Grove Middle School in Minnesota, USA, implemented a "cell phone ban" last year, prohibiting students from using mobile phones during the school day from 8:10 a.m. to 2:40 p.m. One year after the policy was implemented, there were significant positive changes within the school. Principal Patrick Smith said this measure not only makes students more focused on learning, but also promotes interaction among peers and reduces bullying on campus.
Before the cell phone ban was implemented, students at Maple Grove Middle School were mostly addicted to their mobile screens, and interactions between classmates were rare in the hallways. Smith recalled that students not only stopped communicating between classes, but also lacked interaction when face to face. This phenomenon seriously affected students' social skills and campus atmosphere. In addition, the proliferation of social media information brought by mobile phones has also become a trigger for student conflicts. Smith pointed out that the widespread use of mobile phones among teenagers not only distracts their attention, but also leads to many unnecessary conflicts and frictions. https://www.silencejammer.com...-cell-phone-blocker
After the cell phone ban was implemented, the campus atmosphere at Maple Grove Middle School changed significantly. Students participated more actively in discussions in class and began to actively communicate with classmates during breaks. Principal Smith said that students' participation in class has increased significantly, and interactions between classmates are more frequent and sincere. The hallways are once again filled with laughter and conversation, and instead of just looking down at their phones, students are beginning to value face-to-face communication. This change not only improves the campus atmosphere, but also enhances friendship and trust among students.
Mobile phone bans have also played an important role in reducing bullying in schools. Smith noted that bullying in schools dropped significantly after the ban was implemented. Students no longer have misunderstandings and conflicts due to information on social media, which provides them with a more harmonious learning environment. Parents also appreciate the change. Kim Gillen, a parent of a student, spoke of the positive changes in her children after the ban was implemented. She mentioned that the children were more attentive and active in class, and the teachers also spoke highly of it. Gillan said that as a parent, she feels very gratified and satisfied to see her children flourish in such an environment.
Although there is no concrete data to prove that students' academic performance has significantly improved due to the mobile phone ban, feedback from parents and teachers shows that children's overall performance has improved significantly. Parents generally believe that the mobile phone ban has had a positive impact on children's study habits and social skills. Principal Smith also firmly believes that this policy will have a profound impact on students in the coming years.
The successful experience of Maple Grove Middle School has aroused widespread attention and discussion in the education community. Many schools and education experts believe that mobile phone bans are an effective management tool that can improve students' learning environment, increase classroom participation, and reduce the negative impacts of mobile phone use. Supporters believe that reducing the use of mobile phones can reduce students' risk of Internet addiction, protect their physical and mental health, and cultivate better learning and living habits.
However, there are also some opposing voices who believe that completely banning mobile phones may not be the best way to solve the problem. In modern society, mobile phones have become an indispensable tool in people's daily lives. A complete ban on their use may trigger resistance among students and affect the cultivation of their digital literacy. Some education experts suggest that schools can help students learn to use mobile phones at appropriate times and occasions by formulating reasonable usage regulations and educational guidance, thereby achieving the dual goals of ensuring learning effects and improving digital skills.
Despite the controversy, Maple Grove Middle School's practice undoubtedly provides a valuable reference case for other schools. How to effectively manage the use of mobile phones in the education process is still a topic that requires continuous exploration and practice. For education policymakers, the key is to find a balance so that students can enjoy the convenience brought by technology while maintaining good study habits and healthy lifestyles. As more schools try and implement similar mobile phone ban policies, they may be able to accumulate more data and experience, further optimize education management strategies, and create an environment more conducive to learning and growth for students.
Is it more comfortable to play games in the car than on the phone?
Jammer B. | 19.06.2024 0 0
As a "homebody" who likes to play games, I have bought many 3A-level works. Some of these games are played frequently, and some are played for one or two hours after they are bought. In short, I think I have a lot of experience in games. In most people's inherent impression, general games are played on computers, mobile phones or consoles, but the current domestic new energy vehicles have very rich functions. Some of them can already play games in the car, and I came into contact with this by chance.
https://www.silencejammer.com...-cell-phone-blocker
I remember that day's calendar, the unit showed a very busy side, and my colleague and I were assigned to Taiyuan on a business trip, but the vehicles in the unit were all dispatched, so in the end my colleague and I drove the Han EV Genesis Edition (715km Honor Edition) to Taiyuan. And along the way, my colleague let me see the charm of pure electric models. First of all, the Han EV Genesis version has a very fast start and acceleration. Compared with cars, it is always one step faster, and the quietness in the car is also very good. Even when the speed is 120 kilometers per hour, there is only a little wind noise in the car, and the overall experience is quite good. At the same time, the air conditioning of the Han EV Genesis version is quite sharp. It is about minus 10 degrees here, but the air conditioning of the Han EV Genesis version can still heat up very quickly. You almost don’t need to wear a coat in the car. It feels very comfortable.
Of course, this car also has several obvious shortcomings. The first one is that its seat is not very supportive of the body. When encountering turning conditions on the highway, perhaps because I am wearing a seat belt, although it will not make my body tilt, but the body will still have a greater sense of shaking. Fortunately, its chassis has good shock filtering ability, so that I, who am a little carsick, will not feel too embarrassed.
When we got off the highway and came to the city, this car was much better in the city than on the highway. Even in a traffic jam, the braking and starting of the vehicle would not give people a turbulent feeling. Of course, this may be inseparable from my colleague's superb driving skills. However, when we got the documents, my colleague wanted to go to his girlfriend with the attitude of "since we were here, I naturally couldn't follow him", so I took a rest in the back seat of the car. The rear space of this Han EV Genesis Edition is not like a medium or large sedan at all. I am 1.8 meters tall and can hardly lie down horizontally. Even if I sit upright, I will feel my head hitting my head, which is in sharp contrast to the front seat space.
It is precisely because of this that I discovered a big highlight of my colleague's Han EV Genesis Edition, that is, its car computer can actually play games. After opening the application management and entertainment, you can find that there are many types of games here. The specific operations are not much different from those on the mobile phone, but downloading requires traffic, and this car is not my car after all, so I did not download some games I like to play. Among the downloaded games, as expected, my colleagues and I have been playing League of Legends (of course, it is a mobile game). So I opened this game with a skeptical mood, and in order to avoid network problems that lead to pit teammates, I chose to customize, and the effect was surprisingly good. There was no lag or disconnection during the whole process, and even the release of skills was quite smooth.
Russian GPS signal interference may cause civil aviation crashes

If someone turns off your headlights when you drive at night, it's dangerous. Two Finnair flights from Helsinki to the Estonian city of Tartu were forced to turn around and return to Finland due to GPS interference
https://www.silencejammer.com...-cell-phone-blocker
On Thursday and Friday, two Finnair flights from Helsinki to the Estonian city of Tartu were forced to turn around and return to Finland due to GPS interference because they could not safely fly to their original destinations.
Lithuanian Foreign Minister Gabrielius Landsbergis told the Financial Times: "If someone turns off your headlights when you drive at night, it's dangerous. The situation in the Baltic region close to the Russian border has now become too dangerous to ignore."
https://www.silencejammer.com
Estonian Foreign Minister Margus Tsahkna added: "We believe that what is happening with GPS is part of Russia's hostile activities, and we will definitely discuss this with our allies." Tsahkna stressed: "This behavior is a hybrid attack that poses a threat to our people and security, and we will not tolerate it."
Tens of thousands of civilian flights have been affected by GPS jamming in recent months, according to experts. The jamming affects all GPS users in the region, and it has also blocked signals used by ships in the Baltic Sea, leading the Swedish navy to issue a warning about shipping safety.
GPS jamming is easy to carry out using relatively cheap equipment, according to experts. No country has admitted to being behind the jamming of signals in the Baltics, but officials in the region say there is no doubt that Russia is behind the jamming both on its home turf and in its Kaliningrad enclave between Poland and Lithuania on the Baltic Sea.
One theory is that Russia is trying to protect Kaliningrad from potential attacks by Ukrainian drones, a senior official said. The Kremlin did not respond to a request for comment. London confirmed in March that a government plane carrying British Defense Secretary Grant Shapps had its GPS jammed near Kaliningrad on its way home from Poland.
GPS expert Dana Goward said: "The chances of an incident are rising." Goldwater, who is president of the GPS user advocacy group Resilient Navigation and Timing Foundation, added that while there are backup systems, crews receive less training on them than on GPS and that "without GPS, aviation will be less efficient and less safe".
However, Juho Sinkkonen, head of flight operations at Finnair and a 22-year pilot, said GPS interference has been increasing since 2022 and is "just a disruption and does not have an imminent impact on safety".
Sinkkonen added that most airports have equipment that allows aircraft to land without GPS, but Tartu "is one of the few airports where a GPS signal is required to prepare the landing procedure".
"We take these incidents seriously. Our relevant agencies are in contact with colleagues in other countries", said Latvian Foreign Minister Baiba Braže. Experts say there are several different sources of GPS interference, one of which appears to be located in Kaliningrad, another responsible for interference in Estonia and Finland, and a separate source affecting Norway and the northernmost part of Finland.
Baltic officials are discussing GPS jamming with allies and urging Russia to stop endangering civilian aircraft. "Allies should not remain indifferent to Russia's jamming of GPS signals and thus endangering international air traffic," said Marko Mihkelson, chairman of the Estonian parliament's foreign affairs committee.
GPS positioning system technology trends in future military warfare
Jammer B. | 22.06.2024 0 0
With the continuous advancement of military technology, the role of GPS positioning systems in future wars will be even more significant. This article will explore the development trends and application prospects of GPS technology in future military warfare. https://www.silencejammer.com...-cell-phone-blocker
Preliminary application of GPS in war
The GPS positioning system was first used on a large scale in the 1991 Gulf War, showing its great potential in modern warfare. By using GPS receivers carried in jacket pockets, Allied forces were able to operate effectively in mapless deserts. These receivers provide precise position information and solve navigation problems in complex terrain.
In addition, GPS technology is also used in the inertial navigation/GPS module integrated system, allowing the hit accuracy of missiles and guided bombs to reach 9 meters. These systems allow airborne bombs to carry out precise strikes at night and in adverse weather conditions, significantly improving the Allied Forces' combat capabilities.
GPS technology breakthrough in the new century
With the development of technology, GPS positioning systems have shown greater potential in military applications. The following are several important trends in the future development of GPS technology:
Innovative track design
Europe has made significant progress in navigation and positioning satellite research. The first-generation systems include the Global Navigation Satellite System (GNSS) and the European Geostationary Navigation Overlay Service System (EGNOS), which combine the advantages of GPS positioning and geostationary communications satellites. The "Galileo" solution in the second-generation system adopts an innovative orbit design. It is an independent system, is open, and is compatible with GPS. This system also has broad application prospects in civil aviation, safe approach and landing of aircraft and other fields.
Development of anti-jamming and jamming technologies
In order to prevent enemy interference, the United States will use a new signal structure on the seventh GPS-2F satellite launched in 2005 to improve signal confidentiality and anti-interference capabilities. The United States is developing a GPS receiver application module (GRAM) that is immune to interference and spoofing and a selectively exploitable anti-spoofing module (SAASM). Receivers equipped with these two GPS modules are called "Department of Defense Advanced GPS Receivers" ( DARG). In addition, the United States is also developing microstrip adaptive antenna arrays to protect military aircraft from using GPS, and has developed small GPS jammers to prevent enemies from receiving GPS signals.
Technical Measures to Improve Navigation Signal Performance
Currently used analog cesium clocks suffer from difficulties in performance prediction and environmental impact. To improve this, computer-controlled digital cesium clocks are being developed to optimize their performance by adjusting internal parameters and compensating for environmental effects.
In short, the role of the GPS positioning system in future military wars will be more significant. Through continuous innovation and technological breakthroughs, the GPS system will provide stronger support for military operations and ensure that technological advantages are maintained in future wars.

On-board signal power adjustable technology
On-board signal power adjustable technology is a way to achieve power enhancement. This technology is implemented through the on-board control system and power management program. It does not require additional payload hardware and will not increase the burden on the satellite platform and power system. The GPS-2F satellite uses this technology to achieve a 7dB power increase in military navigation signals. Although the power increase is limited, this technology is less difficult to implement and is an effective means of power enhancement. https://www.silencejammer.com/gps-jammer-blocker-car-signalhttps://www.silencejammer.com/mobile-jammer-cell-phone-blocker
test verification projects show that power enhancement is still an important technical way for the U.S. Air Force to enhance the anti-jamming capability of the GPS system. Through the verification and application of these technologies, the anti-interference ability of the US GPS system will be further improved.
Military application prospects
The application of power enhancement technology in the military is of great significance. By improving the anti-interference capabilities of navigation signals, the United States can ensure the stability and reliability of navigation services in complex electromagnetic environments. In the future, with the development of spot beam technology and on-orbit reprogrammability and signal reconstruction technology, the application prospects of U.S. GPS systems on the battlefield will be even broader. The application of these technologies not only enhances the navigation capabilities of the US military, but also enhances its information advantage on the battlefield.
in conclusion
Power enhancement technology is an important means to improve the anti-interference ability of satellite navigation systems. The United States has significantly improved the navigation service capabilities of the GPS system through on-board signal power adjustable technology and spot beam technology. Driven by the Navigation Technology Test Satellite-3 project, these technologies will be further developed and applied in the future to provide more reliable navigation services for the US military on the battlefield. The widespread application of power enhancement technology will ensure the United States' leading position in the field of military navigation.
Mobile phone management in modern schools
Jammer B. | 24.06.2024 0 0
1. Advantages
Smartphones provide students with convenient learning tools and resources. Through mobile phones, students can quickly find information, complete homework and participate in online learning. In addition, applications such as calendars and memos in mobile phones can help students better manage time and tasks and improve learning efficiency.https://www.silencejammer.com/
2. Disadvantages
Although mobile phones have many advantages, their disadvantages are also obvious. First, social media and games on mobile phones can easily distract students and affect classroom discipline and learning effects. Second, frequent use of mobile phones may have a negative impact on students' eyesight and mental health. In addition, mobile phones may also lead to social isolation among students and reduce opportunities for face-to-face communication.
The necessity of mobile phone management
In order to give full play to the advantages of mobile phones and mitigate their negative effects, modern schools need to formulate reasonable mobile phone management strategies. Proper mobile phone management not only helps improve learning outcomes, but also creates a more focused and healthy learning environment.
Mobile phone management strategies
1. Establish a clear mobile phone use policy
Schools should establish a clear mobile phone use policy to stipulate the time and scope of mobile phone use by students during school. For example, students can be required to turn their mobile phones to silent or off mode in class, and only use them during breaks or specific time periods. In addition, schools should explain the importance and necessity of these policies in detail to students and parents to gain their understanding and support.
2. Use mobile phone blockers
In order to prevent students from using mobile phones in class, schools can consider using mobile phone blockers. This device can block mobile phone signals in the classroom, making it impossible for students to use mobile phones during class, thereby avoiding distractions and interference. Of course, when using blockers, attention should be paid to emergency communication issues to ensure that students can contact their parents or teachers in an emergency.
3. Education and guidance
In addition to technical means, education and guidance are equally important. Schools should educate students on the importance of reasonable use of mobile phones and cultivate their self-discipline through lectures, courses, etc. Teachers should also guide students to focus on learning and reduce their dependence on mobile phones in class.https://www.silencejammer.com/p-adjustable-vhf-wifi-gps-jammer
4. Home-school cooperation
Mobile phone management is not only the responsibility of the school, but also the support and participation of parents. Schools should maintain close communication with parents, jointly formulate and implement mobile phone use regulations, and help students develop good mobile phone use habits. Parents can strengthen supervision of their children's mobile phone use at home to ensure that they can use mobile phones reasonably in their spare time.
Banning mobile phones from classrooms in colleges and universities
Jammer B. | 25.06.2024 0 0
In recent years, with the development of technology, it has become increasingly common for college students to use mobile phones and tablets in class. The Jiangxi Provincial Department of Education recently issued a regulation that prohibits students from using mobile phones and tablets in class unless necessary for teaching. This provision sparked widespread discussion.https://www.silencejammer.com
Many students and netizens expressed support for the ban, believing that mobile phones can easily cause distraction and affect learning results. Guo Jing, a sophomore majoring in law, pointed out that using mobile phones in class can distract attention, making it impossible to fully digest class knowledge. Moreover, some students even forget to take exams because of playing on their mobile phones, which affects their studies.
Some schools have taken steps to reduce students' use of mobile phones in class. For example, a university in Tianjin sets up mobile phone pockets in classrooms, and teachers or class leaders organize students to hand in their mobile phones before class. Although this measure was effective in the early stages, as time went by, students found various ways to circumvent it, and the effect gradually weakened.https://www.silencejammer.com/mobile-jammer-cell-phone-blocker
Not only in colleges and universities, the problem of addiction to mobile phones among primary and secondary school students is also becoming more and more serious. According to a report released in 2018, nearly 70% of Chinese primary and secondary school students own smartphones. Some local governments have issued regulations prohibiting primary and secondary school students from using mobile phones during school hours. For example, the Education Bureau of Zunyi City, Guizhou Province has stipulated that starting from June 2019, primary and secondary students will be completely prohibited from bringing smartphones and personal tablets into campus.
Lei Yanqin, a deputy to the National People's Congress, put forward a proposal calling for a complete ban on the use of smartphones by primary and secondary school students in schools. She believes that although smartphones are helpful for contacting family members and finding information, they also have many negative impacts, including affecting academic performance, physical fitness, and mental development.
In addition, Lei Yanqin suggested that the school formulate relevant regulations and implementation details to make it clear that it is illegal for students to bring mobile phones to campus, and the school has the right to require parents to cooperate and impose appropriate sanctions. At the same time, parents should actively cooperate with schools and avoid buying smartphones for their children.
New Zealand schools to ban mobile phones to improve education quality
Jammer B. | 26.06.2024 0 0
New Zealand Prime Minister Christopher Luxon recently announced that a nationwide ban on mobile phones will be implemented in schools. The decision is a key initiative by Luxon's new government to combat New Zealand's declining literacy levels. https://www.silencejammer.com...-cell-phone-blocker
New Zealand's literacy scores were once among the best in the world, but now reading and writing standards have dropped significantly, leading researchers to call it a "classroom crisis". Luxon said he would push for the ban within 100 days of taking office and learn from similar policies in the United States, Britain and France.
Luxon explained that the policy will help reduce disruptive behavior in the classroom and improve student concentration. "Our goal is to allow students to focus on learning while enabling teachers to better teach the curriculum," he said.
According to a report by New Zealand charity Education Hub, more than one-third of 15-year-old children will be barely able to read and write in 2022, reflecting the serious literacy crisis facing the country. Researchers stress steps must be taken to improve literacy in New Zealand.
Luxon's conservative government was sworn in on November 27 and faced controversy in its first week in office when it unexpectedly rolled back a world-leading anti-smoking measure. Former Prime Minister Jacinda Ardern's government introduced a "generational smoking ban" that banned the sale of cigarettes to people born after 2008. Doctors have warned New Zealand faces a looming public health "tragedy" after the measure is lifted.
Owners of a residential complex in Sichuan are worried about the radiation of mo
Jammer B. | 27.06.2024 0 0
Starting from October 6, mobile phone signals suddenly weakened or even disappeared inside and outside the Huayi Sunshine Community in Pidu District, Chengdu City, Sichuan Province, with China Mobile being the most obvious. It turned out that due to the weak mobile phone signal in the community, the operator was opposed by some owners when setting up signal equipment in the community during the National Day holiday, which alarmed the local information data center and the police. https://www.silencejammer.com...-cell-phone-blocker
Three days later, a joint notice signed by China Telecom, China Unicom, China Mobile and the tower company appeared at the entrance of the community, "Due to the notice from the property management, some residents in the community complained that the mobile phone signal equipment in the community interfered with the normal life of these owners. After communication and explanation failed, the three major operators will interrupt and stop the operation of all mobile phone signal equipment in the community."
Located in a prosperous area, the community has become a mobile phone signal "jammer"
Originally located in a prosperous area with commercial and residential areas, the Huayi Sunshine Community in Pidu District has recently become a mobile phone signal "jammer". Outside the gate of the community, the signal on the reporter's hand was flickering. The China Unicom phone card was slightly better, but the mobile phone card would occasionally lose signal and last for a long time.
The owner of the fruit and vegetable store at the entrance of the community was unusually idle throughout the morning. The less than 200 yuan he received on WeChat proved this point. "Usually, WeChat would receive nearly 1,000 yuan in the morning, just because the signal was not good. Many customers could not transfer money by scanning the code on their mobile phones, and they did not bring cash, so they finally did not buy anything." The other party said that this situation has lasted for several days. https://www.silencejammer.com
Next to the fruit and vegetable store, Hongqi Supermarket, convenience store, etc., all encountered the same situation without exception. A supermarket cashier said that after the customer selected the items, he found that he could not scan the code to pay, and put the items back awkwardly and left. The other party took out his mobile phone, and the mobile signal was very weak. "Sometimes the phone could not be dialed." The reporter walked into the supermarket, and the mobile signal disappeared. The reporter asked the owners in and out of the community one by one, and most of them said that the mobile phone signal in the community has always been poor, "It is very inconvenient to make calls at home, and you can't receive calls." So, how could such a situation occur in a commercial and residential community with thousands of people?
On the rooftop of the 30th floor of Unit 1, Building 7, the wires of the signal amplifier were damaged.
What is the reason?
Property manager Hu Deyu said that since moving in in 2015, the mobile phone signal in the community has been very poor. "Our property is in the commercial area outside the community. As long as I walk into the office, no one can contact me. Complaints about poor mobile phone signals have never stopped." A staff member of the Pidu District Information Data Center said that the poor signal in the community is related to the dense density of this building. In addition, the number of owners moving in is increasing, and the mobile signal equipment cannot keep up. The community property has repeatedly asked the operator to add mobile phone signal equipment.
During the National Day holiday, engineers from the mobile company entered the community and set up new mobile phone signal equipment on the rooftop of the elevator apartment building. Some owners discovered and were blocked. The conflict was imminent. The owners who opposed the new mobile signal equipment found the property and asked for it to be removed. The reporter contacted two owners who held opposing opinions. The other party said: "The new equipment has radiation and will cause harm to the human body. Now the mobile phone signal can be used and is not bad."

In the context of globalization and informatization, enterprises are facing unprecedented information security challenges. Commercial espionage and information leakage incidents are emerging in an endless stream, seriously threatening the core interests of enterprises. In response to these threats, some enterprises have begun to use high-tech means such as jammers to protect their own interests. This article will explore the role of jammers in corporate information security, as well as their legality and ethical issues.https://www.silencejammer.com
Challenges of corporate information security
With the development of the Internet and wireless communication technology, corporate information transmission and storage are increasingly dependent on the network. However, this also makes the information security threats faced by enterprises increasingly greater. Criminals can steal corporate confidential information through a variety of means, including business plans, technical documents, and customer data. Once this information is leaked, it may cause huge economic losses and reputation damage to the company. https://www.silencejammer.com...-cell-phone-blocker
Application of jammers
In order to protect the core interests of enterprises, some companies choose to use jammers to block the communication signals of criminals. Jammers interfere with or block communication signals in the target area by emitting electromagnetic waves of a specific frequency to prevent information leakage. For example, some companies install jammers in important meeting rooms to prevent competitors from obtaining meeting content through eavesdropping devices. In addition, companies can also use jammers in sensitive areas such as R&D centers and data centers to prevent internal data from being stolen by outsiders.
