Talk about the summary of experience when installing jammers in prisons

A. Most prisons have guard towers and observation towers to protect prisoners. The height of the towers is mostly higher than the prison buildings. If the antenna height is higher than the tallest building, it will be easier to block cellular phone signals in the air. Therefore, it is very easy and more protective to install the prison shield on the observation tower. Moreover, engineering costs can be greatly saved. The installation process can be improved.

B. If there is no prison guard tower or its use is not allowed, we suggest that you can choose a fence. If the height of the wall is higher than the tallest building, solution a can be used. If the wall is lower than the tallest building, a fixing bracket must be installed on the wall. The height of the support must be 3 to 5 meters higher than the tallest building in the prison. The higher it is, the easier it is to install the antenna. In this way, the construction cost will be higher than solution a. If it is a larger prison, more shields must be installed to adopt solution a and solution b. We recommend installing wireless jammer with omnidirectional antennas on some buildings in the middle of the prison to increase the shielding range and reduce the amount of interference.

C. If all guard towers, prison buildings and fences in the prison are not allowed, we must recommend the construction of some fixed cylindrical towers or signal towers. Engineering costs will be more difficult and expensive. The whole building will be much slower. To some extent, once other solutions cannot be adopted, this is our last choice.

Tip: If you use plan B and plan C, please pay attention to install lightning rods. The height of the lightning rod must be 2M higher than the antenna. jammer-mart has many years of experience in the installation of signal jammers in prisons. It is also very experienced in projects in other places. At the same time, you can choose the jammer products that suit you on our website.

How to shield a base station within 800M

As we all know, the base station is to enhance the signal, and the shield is to shield the signal. The two conflicts with each other. This is a headache for many government agencies that need a shield. Today, I will show you how a prison with base stations around is fully shielded through our scheme.

It is well known that the prison cannot have a signal, but there is a base station within 800 meters of the prison. The prison has tried many electronic jammer devices, but the effect is not satisfactory. There are always signals in many places, which brings great risks to the prison. Our technicians personally took the equipment to the site to investigate the signal strength and site conditions.

(1) There are many residents around the prison, especially in the southeast direction. The shielding project cannot affect the normal communication of the surrounding residents. Therefore, the selection of the shielding project and the design plan require precise and accurate shielding, which is difficult to design.
(2) The new prison administration office building near the factory area and the old prison administration office building in the living area belong to the police office area and cannot be shielded in principle
(3) There is a large communication tower at the location of the prison office building, which will inevitably cause strong mobile phone signal strength in the entire supervision area, and the field strength value is much higher than that of Canggu. The design of the shielding project is difficult.
(4) There is also a communication tower about 800 meters northwest, which will superimpose the signal strength of mobile phones in the supervision area.

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.

Good reasons for using cell phone jammers in cinemas and theaters

Usually, when entering a movie theater or theater, turning off the phone is the most basic ceremony. However, in any case, some people will ignore these rituals and rules. Yes, when you watch a movie, you are always interrupted.

Try to convince people to observe the most basic social considerations in the movie. If you have visited a theater recently, you know they are often overlooked, so other methods have been explored to enforce theater ethics.

For new and popular movies, the theater may have a separate auditorium to block cell phone use, but the auditorium does not block the signal. This is more like the tradition of non-smoking areas in restaurants. Although the use of mobile phones is still discouraged in closed auditoriums, those who choose to watch movies will have to deal with occasional distractions.

Why use a cell phone jammer?

Hollywood film blogger Alex Billington (Alex Billington) is one of many people who rejoice in the rapid retreat of AMC. “Texting in the theater completely ruined the movie,” he said. “This is something we must fight on the social and cultural level.”

In 2014, a dispute between two men texting at a cinema in Florida eventually led to a fatal shooting. Although this is an extreme situation, most people would agree that the illuminated cell phone screen and finger taps can be annoying.

Phone calls are not just a hassle for movie theaters. When Benedict Cumberbatch played Hamlet in Barbican, he finally added a monologue, lamenting the tragedy of cell phone cameras and urging his fans to put down their phones. Some performers take the problem of disruptive technology completely in their own hands.

Have these people never participated in a movie so fully, or felt so deeply involved in a story that when something sounds or shakes or lights up a few seats, they don’t feel a momentary resentment, Smashed this spell? The problem started with a lack of respect for seat partners, or lack of respect for the entertainment media itself?

Of course, the reality is that all of these are important. In an era when we are forever consumed by our personal technology, the theater can and should be our last public refuge, and we can only be affected in movies and films. If that vision comes from a nostalgic or naive place, then this place is still a space for all of us, sitting proudly and provocatively in the dark.

Personally, I think theaters should be allowed to install cell phone signal jammer and there are clear signs that they are being used. If people don’t like this, they are free to spend money elsewhere. If all theaters eventually use the technology, then these people can choose not to go to the movies.

USS Boxer used electronic interference to take out Iranian drones, Pentagon sources say amphibious assault ship

The USS Boxer deployed electronic measures to dismantle a drone the US says was operated by the Iranian military, according to Pentagon sources familiar with the situation. The Navy says the drone was wrecked on the Strait of Hormuz on Thursday after it approached the ship and repeated warnings went unheeded.

Iran has denied the US claims, stating that all of its drones will be considered – and that the US ship may have accidentally shot down one of its own military drones.

U.S. Department of Defense officials, who were not empowered to speak publicly, said the drone was one of several threats to the boxer as he drove through the narrow waterway near the Iranian coast. It is said that at least one Iranian helicopter and several fast boats drove towards the ship on Thursday morning. The actions prompted the boxer to send a helicopter, which then flew side by side with the Iranian plane to repel him.

The boats eventually followed radio warnings to break contact, but the drone headed for the boxer instead of turning, the sources say. His presence was seen as a potential threat to flight operations aboard the amphibious assault ship, which carries a number of helicopters, as well as Osprey tiltrotor aircraft and a handful of fighter jets.

There were also concerns that the drone could pose a direct threat: in recent months, Iran-backed Houthi rebels have been using drones to drop explosives on targets in both Yemen and Saudi Arabia. According to a Pentagon source, the drone was unarmed in Thursday’s encounter.

The first US statements about the incident with the boxer did not contain any detailed information about the crash of the drone. On Friday, a Pentagon official clarified that the boxer was using electronic jammer measures to turn off the drone. The officer did not provide details in order not to disclose information about the ship’s capabilities.

The news site Military.com states that a new Marine Corps anti-drone system was responsible for the Iranian drone crash, although the military did not confirm the report. USNI News notes that the Navy previously announced that the Marines were operating the jamming system on the deck of a US ship. USNI News described the weapon as one of a new series of “non-kinetic systems” that can cause a drone to crash.

President Trump first announced the crash on Thursday afternoon, saying “The drone was destroyed immediately” after closing within about 1,000 meters of the boxer and ignoring the request to resign.

Shortly after Trump’s testimony, Pentagon spokesman Jonathan Hoffman gave further details, saying a drone approached the Navy ship at around 10 a.m. local time while the ship was in international waters and on an “inbound road transit” von Hormuz “sailed. “”

However, on Friday, Trump said the U.S. ship shot down the drone, contradicting Pentagon officials’ report that the boxer was using jamming features. “No doubt no,” Trump said in the Oval Office, according to a White House pool report. He added, “We shot it down.”

When asked if he was concerned about the possibility of a major clash with Iran in the Strait of Hormuz, the pool report quoted Trump as saying, “No, not at all. … We hope they don’t do anything stupid about them. ” When they do that, they pay a price no one has ever paid before. ”

Also on Friday, a senior Trump administration official said the U.S. government had evidence that the boxer destroyed the drone and said more information about the shutdown would come from the Pentagon.

“We have very clear evidence, the Department of Defense issued its statement on the boxer’s actions,” the official told reporters on Friday. “The Iranians don’t have a great story with the truth. We are very confident in the president’s announcement.”

When asked if the Trump administration would take further action against Iran, the official said the US was ready to defend itself.

“It was your drone that approached our ship,” said the officer, adding, “If you keep doing this. If you fly too close to our ships, you will be shot down.”

US military officials say Iranian helicopters and drones often flew near US ships as they crossed the Strait of Hormuz between the Persian Gulf and the Gulf of Oman.

In an incident that began in August 2017, according to these officials, a US ship was harassed by an Iranian drone that flew near the ship during night operations. No shots were fired, but the encounter was classified as “clearly unsafe”.

What are the effects of communication base stations on the social economy?

Why build a communication base station?

Regardless of the mobile communication system, the calling and called users do not directly transmit information. The calling user transmits the demand signal and transmits it to the central computer room through the base station. The central computer room analyzes this information, determines the location of the called user, GSM jammer and transmits relevant information to the base station near the location of the called user, and the base station transmits to the called user. Since each base station has coverage distance and access capacity limitations, it is necessary to build multiple base stations to form a communication network to achieve seamless coverage of the entire area.

What is the effect of mobile communication on the social economy?

The development of mobile communications has had a profound impact on the reform of the telecommunications industry, economic growth, independent innovation and social life.

First, it has promoted the change of Chinese people’s concepts and led to the rise of communication culture. Over the past 20 years, my country’s mobile communication network has continuously expanded its coverage and enriched business content, expanding the breadth of people’s communication, deepening the depth of people’s communication, expanding the time and space of communication with each other, and accelerating people’s ways of thinking, working, and Changes in lifestyle. The reduction of information exchange cost brought about by convenient mobile communication has expanded people’s information sources and effectively promoted the improvement of national quality.

The second is to promote the improvement of social and economic operation efficiency and economic development. Through continuous innovation in business services, my country’s mobile communications industry has effectively helped related industries to reduce operating costs, avoid operating risks, improve management efficiency, promote the improvement of social and economic operation efficiency, and bring double value that is difficult to measure with money.

The rapid development of my country’s mobile communications has played a positive and direct role in attracting foreign investment, becoming a global electronic communications manufacturing base and important research and development center, and has promoted my country’s mobile communications manufacturing enterprises to enter international competition, thereby changing mobile communications systems and mobile phones. The global layout of the manufacturing industry has greatly stimulated the development of the domestic communications manufacturing industry and even the global communications manufacturing industry.

The third is to promote environmental protection. In 2009, the “thumb economy” represented by mobile phone text messages for New Year greetings reappeared. According to estimates, the number of mobile phone text messages sent nationwide during the Spring Festival holiday exceeded 18 billion. Compared with the previous paper greeting cards, 4,000 paper greeting cards are about one tree. Calculated, it is equivalent to cutting down 450,000 trees. In today’s era when paperless office is promoted, mobile communication platforms extend this concept to the extreme.

Homemade jammer GPS navigation systems sometimes affect our privacy

Safe and legal use of frequency blockers

More and more people are concerned about their privacy. Recently, in the United States, Facebook users have stolen private data, causing people to think on different levels. We all know that many new wireless devices can steal our personal information, even we don’t even know.

We use different devices every day, including GPS navigators, laptops, laptops and smartphones. But many people don’t even know that male factors will steal their personal information, and their wireless devices are their dual agent.

We use Wi-Fi connection, but we don’t know how easy it is to hack. We use Bluetooth, but we have never heard of bluesnarfing. Of course, we use GPS to know where we are and how to get what we need, but have you heard of GPS navigators?

From this perspective, I understand why these mobile phone jammers are very popular in many countries around the world. They are usually used for protection because people want to protect their privacy and the privacy of people who care about them.

As I said before, these jammers, GSM signal blockers or mini gps jammer have been used in many countries/regions in the world. But if you read about these painful ways of working, it will be better. Another important information is the frequency of the interference signal used. Many people use these signals for rate jammers, so I tried to find some simple principles for using jammers safely without harming anyone.

gps car signal jammer

In the United States, there are no restrictions on the use of interfering devices, but transmission on certain frequencies is prohibited without permission. But I believe that if your privacy or the privacy of the people you care about is at risk, then all means are sufficient. But you must remember that we must not forget the rights of others. There are some simple principles for safely using jammers.

1. Do not use jammers in public places. We recommend that you use private interference devices. Do not open it in public places, otherwise it will hurt others. You can freely use the jammer in the car or at home. In addition, please try to choose a jammer that matches your work space, because some of your neighbors are in areas where there is no signal.

2. Protect your privacy without disturbing others. You must remember that other people want to communicate freely. Don’t try to make her sad. Remember that if the jammer is on, no one on the phone will ring, not even 911. Do not use jammers in police stations or hospitals near cars.
