From ancient times to today, security has always been an important aspect, such as military, network and many other fields. In this case, we need to use different types of security tools in different areas, such as WiFi jammers, which can protect the network security.

In order to ensure a safe environment, various safety measures have been taken in different locations and regions. For example, in factories, hotels, schools, and many other places, we can usually see that in many places, maintenance personnel of buildings should register first. All of this is to ensure security. We can see that security plays an important role in different regions and networks. Now, more and more people are accepting wireless network jammer devices.

What are the advantages of wifi signal jammer?

The development of smart phone wireless networks has a great effect on increasing the speed of development. Mobile phones can solve network problems. Mobile phones play a more important role in people’s lives, mobile communications and mobile Internet, and other aspects. Because of this, it causes a lot of problems, especially in the network, children are addicted to the Internet, which is mainly due to the wifi network. As a result, many gradually began to install mobile phone wireless jammer devices to block the network in order to control the children’s online time.

High tech Phone Wifi interceptor

Although wireless networks are convenient for people to access the Internet, the problems caused by this cannot be ignored. This is not only a problem of accessing the network, but also a problem of network security. In order to maintain a good network environment, many places have begun to install this desktop wifi shield to protect the network security in some places and prevent excessive use of the network. This equipment has been widely used in various countries and regions in the world, and is typical of schools, prisons, libraries, reading rooms and gas stations.

It is necessary to use a Wifi blocker. On the one hand, it can ensure the security of the network. On the other hand, it can also control the time that children use the Internet. Don’t indulge in the virtual world. It is very serious to harm their body and mind. In addition, the radiation of the wifi transmitter will affect Human health is not suitable for long-term use, you can turn on the wifi shield to block the wifi signal.

In general, keeping all shields in an open state for many years is not conducive to energy conservation, environmental protection, equipment maintenance, and shortening the service life of equipment (such as factory areas, canteens, warehouses, etc., are unmanned at night, and there is no need to place these locations. The mobile phone jammer runs continuously 24 hours a day).

The technical solution for seamless coverage of cell phone signal jammer in the whole prison area

1. Jammer-mart provides the following shielding solutions for a prison:
1. For the shielding of the internal area of the building, the distance between residents (schools) and other public facilities in the area where the building is located should be considered, and the distance and signal strength of the surrounding communication rack base stations should also be referred to, so as not to affect the mobile phone signals in the surrounding public facilities. For normal communication, our company selects MDPB-25W indoor host product for the shielding in the building to carry out the network shielding of the indoor antenna mode.
2. For the requirement of shielding all in the selected area, our company chooses outdoor large-scale electronic jammer device to cover the inward coverage of the wall cloth to ensure the shielding of mobile phone signals in all areas. At the same time, for the blind spots and leakage points that may exist in the room, use MDPB-5E is installed with patch point.

Installation Notes:
(1) On behalf of MDPB-25W indoor host, on behalf of indoor antenna line.
(2) No. 1-3 workshops, two MDPB-25W indoor mainframes are used inside, and indoor dedicated distributed antennas are used to realize shielding in the workshops.
(3) The surface price of No. 4-6 workshops is relatively small, just install one MDPB-25W indoor.
(4) The angle of the indoor distributed antenna is adjustable, which can fully guarantee the realization of the shielding effect.
(5) The interior of the factory building, such as the bathroom, is complicated, and a small amount of small shielding MDPB-5E can be used to make up points in a separate room.

Why use signal jammers in educational institutions?

The mobile phone is undoubtedly a very convenient tool. However, depending on the time and place of use, normal public order may also be hindered. Such as libraries, classrooms, etc.

There is no doubt that smartphones have extraordinary functions that can theoretically promote student learning. But the fact is that despite the best efforts of parents and teachers, children still mainly use mobile phones to access digital entertainment.

Needless to say, mobile phones should not be used in classrooms. Mobile phones are not allowed in the classroom, but teachers don’t want to enforce the rules. They often complain that I should find a solution so that they don’t have to argue with students. A friend of mine used to be a teacher. His students used to send text messages in class and later bought a portable cell phone jammer. Then all the students felt that their phones could not receive any signals.

The principal of high school purchases cell phone signal jammer from dealers to prevent students from using cell phones in school in violation of school district policy. First, he may be tired of abusing mobile phones on campus, and his decision may be due to cases where the learning environment he tried to create was seriously damaged. However, it is frustrating that education efforts, deterrence strategies, formal policies, and vigilant supervision and sanctions have not sufficiently reduced the problem.

The school will restrict the use of students’ mobile phones during class, so as to clearly promote students’ academic success and safety. At present, most schools will let teachers install signal jammers in their classrooms. But this piecemeal approach leaves teachers with insufficient support to cope with difficult and potentially unsafe tasks that provoke students to restrict destructive phone use.

Some people think that mobile phones should not be used during learning because children will not be fully focused on their work. Children can go online to play games, but it does not help their learning. Children will be distracted by the ringtones on their phones or the flashes of other children taking pictures with their phones. Mobile phones should not be allowed to go to school during the study period.

In addition to sending text messages, jammers can also effectively prevent students from cheating on their mobile phones. Cheating is always repeated. Facing this situation, educators must use jammers to prevent cheating.

Now not only educational institutions in China are using mobile phone signal jammers, more and more countries are introducing signal jammers into educational institutions.

The demand for anti-cell phone signal jammers is growing

In the past two decades, we have seen a dramatic increase in the number of users of mobile communication devices. This expands the cultural society’s demand for more effective and reliable signal encoders. Mobile jammer devices are becoming civilian products, not electronic warfare devices. With the increase in the number of mobile device users, the need to disable mobile phones in certain places has also increased, where the sound of mobile phones will be harmful. These places include places of worship, meeting rooms, hospitals, concert halls, meeting rooms, prisons and other places where silence is required. cell phone signal jammer is very effective in confidential meeting rooms, because important information may leak from one room to another without knowing anyone else. Jammers are very effective in breaking the communication between prisoners in prisons.

portable mobile phone radio jammer

Whether it’s theaters, educational institutions, cafeterias, restaurants, offices, or anywhere else, almost everyone uses a mobile phone. Today, people spend most of their time on mobile phones instead of spending quality time with their families or focusing on organizational goals. Although mobile phones can help you in many ways, they also distract many lives. This is the source of mobile phone network interference. Interference refers to the act of blocking something. Therefore, mobile device interference refers to preventing network signals from reaching your mobile phone, thereby denying access to the Internet and sending messages via SMS or phone calls.

Where do you need to use a mobile phone blocker?

If you have an emergency meeting and you don’t want anyone to answer unnecessary calls or messages during an important meeting, you can use cell phone blocking technology. This technology allows people to avoid calls and text messages without turning off their phones. Enabling this technology will directly block the signal from the base station and make the person unable to communicate with other people via mobile phones.

Although many people think that installing interfering devices in schools is not a solution, because children can access the Internet in various places, including open Wi-Fi areas at home and in cities, some people think this is a good idea. Adolescent children are not mature enough to use the Internet properly. Sometimes, out of curiosity or under pressure from peers, they may be exposed to content that shouldn’t be included. Installing jamming devices is a very good idea so that even if someone inadvertently does not make the mistake.

Amazon: We’re fixing a bug that leaves the Key Security Camera open to Wi-Fi interference

A malicious courier could easily freeze the key’s cloud camera and roam a customer’s home unattended.

Amazon is fixing a solution to a bug in the surveillance camera that is used to monitor couriers delivering packages to key customers’ homes.

Amazon Key is the recently launched service that allows Amazon couriers to place goods in the homes of Prime customers. The service works in tandem with Amazon’s new Cloud Cam security camera, a smart door lock, and the key app that remotely unlocks the door and displays a live video feed.

However, as Wired reports, Seattle-based security company Rhino Security Labs has discovered a bug in the process that would allow a devious courier to freeze the camera. This ability undermines the key component that gives customers security when they let a stranger into an unattended home.

The attack can be launched within Wi-Fi range, exactly where a hacker courier would be positioned. Using a computer, the attacker sends a volley of “deauthorization” packets to the target cloud camera, preventing them from using an access point when trying to authenticate again. It is a well known technique for wifi signal jammer and not specific to Cloud Cam.

Even though the Amazon camera is offline, it will still display the last image the camera took when it was connected, so the homeowner will not know that the view on their app is not live.

Rhino’s demo video shows a delivery man delivering a package as expected, but after freezing the camera on a picture with the door closed, he re-enters the house. The camera does not record the second entry and the Key app does not log the second entry.

An Amazon spokeswoman told the ZDNet sister site CNET that they are currently notifying customers when Cloud Cam is offline for a “longer period”.

An update released later this week will inform users when the camera goes offline during a delivery. The service will also not unlock the door if Wi-Fi is disabled and the camera is offline.

All major couriers undergo a comprehensive background check that Amazon checks before they can deliver at home, the spokeswoman said. In addition, Amazon links each delivery to a specific driver and verifies that it is the right driver at the right address.

Those mobile phone problems can be solved by jammer

The obsession with mobile phones worries both parents and schools. A middle school found a “new solution”: a mobile phone signal sign is being installed on campus, which can be turned on every night, so that students can’t play with mobile phones at night.

The school intends to block cell phone signals so that students can study, rest and break the idea of play. Mobile phones and games are almost the biggest challenges in education today. A middle school teacher wrote a recently popular mobile phone game, and said that the game has gradually turned mobile phones into “game consoles.” His students also said painfully: “I can’t control myself!”. In order to get students out of the predicament, some unconventional management methods must be used, such as prohibiting the use of mobile phones and playing games. The school needs to do something about this, and shielding the phone signal is much more effective than calling the teacher to inspect the house and adopt strict management measures.

3g jammers

The work of a gsm jammer is very simple, because it affects the frequency of the telephone signal and the frequency of the signal. In recent years, signal interference has been used in various inspection halls, schools, gas stations, courts, libraries, conference centers (halls), theaters, hospitals, government agencies, etc. Even some companies and families are installing them. Interference equipment can be easily purchased on the Internet.

In recent years, with the rapid development of modern communication technology, the use of high-tech fraud methods in examination rooms has emerged one after another, from pagers to mobile phones, to mobile phones, to today’s digital products, and college entrance exams conducted through fraud tools. For cheating tools such as rulers, rubber, spectacle cases, stationery bags, watches, and mineral water bottles, examinations have been carried out in different countries. In order to prevent fraud, the authorities have effectively prevented and stopped fraud in the examination room by using mobile phone locks, metal detectors, radio signal jammers and warning suppression devices.

This bar doesn’t allow cell phones so you’ll be only talking to your friends

Bar culture has changed dramatically in recent years. Since the age of cell phones and smartphones, people haven’t been so busy with each other – a common complaint among bartenders everywhere. To solve this puzzle, a bar decided to block cell service and virtually force customers to talk to each other.

Do you think that sounds crazy? It is kind of. At The Gin Tub in Hove, England, landlord Steve Tyler built a cage around the building to disrupt cellular service. He even went as far as wrapping the walls in aluminum foil and pinning copper wire mesh to the ceiling.

“I’ve seen it get worse and worse and I thought, ‘I want to stop,'” he told the BBC. “I want people to meet with the people they are with instead of the people they are not with.”

And there’s a reason he didn’t go out and buy an official cell phone jammer. “I made the brave decision not to block the signal with a jammer, but to make it as good as possible with a Faraday cage and get people to talk to each other,” he said. “And, to be honest, it worked very well.”

But if you’re worried about being utterly cut off from the outside world during your whiskey, fear not: Tyler plans to designate an outside area for cell phone use, similar to an outside smoking area. And of course the bar is equipped with a landline network for emergency calls.

So far the answer has been all positive. “I had a complaint from a customer and it was that she got a signal,” Tyler said. “We moved her to another table.” Imagine that.

Men’s basketball game reporters restricted due to negative closing venue signal shielding

The 12th National Games enters the final day, and the competition will end today. The closing ceremony of the current National Games will also be held at 4 pm today. According to the notice received by the National Games Propaganda Department last night, the men’s basketball finals interview reporters will implement a quota allocation system, and the closing ceremony will use cell phone signal jammer for communication control.

Powerful signal jammer device

Not long after the men’s basketball semi-finals ended on the evening of the 11th, around 22:00, many reporters covering the National Games received a text message. This official notice from the National Games Propaganda Department stated: Adopt reporters to implement a quota allocation system” and attach the phone number of the forecast name.

The phone of the media director of the Tiexi Gymnasium in Shenyang Division instantly became a “hotline”, and the incoming calls were almost unbroken. More than 50 calls came in within an hour. And these reporters have only one purpose, which is to win interviews for tomorrow’s men’s basketball final.

According to the person in charge, according to the notice issued by the superior, there will be only 20 photojournalists in the men’s basketball final at 13:00 tomorrow, and the relevant photo vest must be obtained to enter the infield. At this time, it is almost impossible for reporters who call to make an appointment to get another photography spot. They can only “register first, and then see the situation.” Regardless of whether it is from the central government, the Liaoning and Guangdong sides in the finals, other provinces, cities, and even Hong Kong, Macao and Taiwan reporters, they can basically get the quota of journalists.

For such a difficult situation, the person in charge is also very embarrassed. “That is 20 places. Xinhua News Agency and CCTV will account for one half. Other mainstream media such as Liaoning and Guangdong will also Give priority to it, so I can only ask media reporters to understand.”

Immediately afterwards, the National Games Propaganda Office issued a notice on the closing ceremony interview. The original text read: “On September 12, during the National Games closing ceremony, communication control will be implemented on the closing ceremony venues, and mobile phone calls cannot be made in the venues. , You can’t use your mobile phone to access the Internet. Please understand that this will cause inconvenience to your work.”

When the reporter called the relevant person in charge of the Propaganda Office, the news was confirmed. As for the consideration of “communication control”, the other party’s initial response was “just received a notice from the superior, and it is not clear.” But then, the Propaganda Office replied: “The main reason for communication control is to worry about malicious hype about the National Games during the closing ceremony, hoping to guide positive reports on the National Games.”
