​To answer this question, you must first know what is called experimental data. The meaning of experimental data is that the test signal shield is in an open environment, and there are no base stations and other things that affect the magnetic strength within 500 meters. The shielding range produced ; What about the actual data? This is very clear, because when the test signal jammer is actually put into use, it is not clear how far the base station is from the test room, or whether there is a need to penetrate walls, so in general, the actual data of the jammer It needs to be actually put into use to know. Now when choosing an exam signal jammer, you must choose a professional one, and a professional machine must be provided by a professional manufacturer.

Telephone jammers are necessary for a good environment for important meetings

We’re tired of being interrupted, especially in important places, and I’m tired of the phone ringing. He was very angry when the leader was chairing an important meeting and was interrupted by the ringing of the cell phone. The frequency jammer is used in the conference room so that the conference has a good environment.

With the popularity of cell phones, cell phone ringtone makes people more tired, especially in some quiet public places. In many places, cellphone use is prohibited as it affects others, affects others to rest or work, and even affect the websites such as the use of the instrument and the moderating effect of cellphone. While there are clear instructions on how to ban cell phone use, there are a lot of people in these places using gas stations for example, as we use cell phone at gas stations is dangerous and probably caused the explosion.

We should know that the important national meeting will last for many days. The content of the meeting must be kept strictly confidential and must not be interrupted by the outside world. Therefore, the mobile phone is prohibited. Not only is this a national meeting, but it was also adopted at a series of corporate meetings where cell phones were banned and cell phone blockers were gradually installed. What do you think is reasonable about Office installation of the cell phone jammer?

Not only are cell phones banned in gas stations, but many public places are starting to ban them. It may also be banned in some private places. We have heard of cell phone jammers being used in schools and cell phone jammers being used in prisons to disable cell phone signals and protect prison security. What about the conference room? Have you seen any examples of this? With people increasingly relying on cell phones, many companies are starting to install an adjustable device in the meeting room. The cell phone jammers will be held in the meeting. The meeting leader conducts the meeting properly without the ringtone intervening. opens and adjusts the disruption area in the conference room. This not only affects the normal use of the outside, but also provides the environment for the meeting.

Pros and cons of mobile phone signal jammer

Nowadays, with the rapid development of science and technology, traditional mobile phones are becoming more and more intelligent, and they have become an important communication tool indispensable in people’s daily work and life. Of course, the negative effects caused by mobile phones are also immeasurable. Negative impacts in special scenarios and specific times have become new leak channels and new criminal methods, posing a threat to the security of confidential information. Therefore, it is urgent to strengthen the management and standardized use of mobile phone signal blockers.

Mobile phone signal jammers are mainly used in places where no mobile phone communication is required, such as in various examinations, office premises of confidential departments, gas stations, etc. Because of their easy installation and simple use, more and more companies use signal blocker. And the equipment signal is always in a relatively static state, which will not interfere with other electrical equipment, and has played a certain role in some special places.

GPS signal jammer

The mobile phone signal jammer is also called mobile communication jammer, mobile phone signal isolator, conference security device, etc.The signal jammer transmits a strong signal consistent with the frequency of the mobile phone’s downlink frequency band, and is tuned with the signal sent by the base station to the mobile phone, so that the base station sends to the mobile phone The downlink signal is deformed and cannot be recognized by the mobile phone, which interrupts the connection between the mobile phone and the base station. Simply put, its main function is to make the phone unable to use normally. Its essence is to implement electromagnetic interference to the wireless network on which mobile phone communication depends, so that the mobile phone cannot access the network, and thus cannot receive information from the mobile network, and cannot send information through the network.

However, with the promotion of signal jammers, it has also brought some adverse effects. The wide use of signal jammers will interfere with the normal use of surrounding residents, causing residents to use mobile phones without signals. If the shielding range is shortened, there will be a lot of It is also difficult to control the blind angle and blind zone, the shielding edge distance, and the long-term coverage is wide, the power will be large, and the radiation generated will also affect the human body. Therefore, the quality of a mobile phone signal shielding device depends not only on the The effective shielding degree of mobile phone communication signals, but also whether the radiation pollution produced by it meets the national electromagnetic radiation protection standards

Especially in government agencies, once the staff of the agency accidentally leaked the content of their work, they could easily be stolen by illegal elements. This is a very dangerous thing for agencies and agencies. In order to prevent such incidents from happening, government agencies will be equipped with mobile phone signal jammers or mobile phone signal shielding cabinets to avoid leaks.

Is the cell phone signal jammer harmful?

It is very interesting that the mobile phone, which is the “enemy” of the cell phone signal jammer, has also caused controversy about security at the beginning of its appearance. However, as people gradually understand the mobile phone, people finally accepted the mobile phone, and In less than ten years, mobile phones have become an indispensable necessity in our lives, and even because of the popularity of mobile phones, a new generation has been born: the thumb generation. This shows the popularity of mobile phones. In the history of human knowledge, the development of one aspect of contradictory things can predict the future of another aspect. Such examples are not uncommon. I think the development of mobile phones as the “enemy” of the mobile phone signal shielding system may be It can provide a blueprint for us to predict the industry picture of the mobile phone signal shielding system.

Finally, I want to tell a true story: when China was building the Daya Bay Nuclear Power Plant in Guangzhou in the 1990s, Hong Kong citizens were very resistant to the project because of the safety of nuclear power. In order to dispel the doubts of Hong Kong citizens, the chief engineer of the project I joked that kitchen knives are also problematic in safety. Kitchen knives can cut fingers inadvertently, and even be used as murder weapons by wicked people. But this does not prevent us from using kitchen knives and does not prevent China from becoming a great food country, because as long as we do our best, we can Can prevent these things from happening. This very superb joke at the time greatly eased the resistance of Hong Kong people to the Daya Bay Nuclear Power Plant and made a small contribution to the smooth start of the nuclear power project.

There is no doubt that technology is a double-edged sword. We all know that mobile phone signal jammers have a certain amount of radiation. In the current situation that there is no authority to define how much this radiation can harm people, what we should do is to start from a people-oriented perspective as much as possible and make good use of technology. Advantages, control and reduction of the disadvantages of science and technology, on the premise of ensuring the safety and health of people, to decide whether to widely use in daily life, not for the uncivilized behavior of a few people, and ignore or even affect the interests of most people .

The 4G wireless signal prevents the mobile phone from making and It can answer, and cannot send or receive text messages, but it will not interfere with the work of other electronic devices, thereby ensuring the safety of the required place. The mobile phone can be used without any damage to the human body after leaving the partition range.

12 Antennas powerful Jammer

Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station and achieve the purpose of shielding the mobile phone signal. The mobile phone appears to search the network, no signal, No service system, etc.

For the shielding of the internal area of ​​the building, the distance between the 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 normal communication of mobile phone signals in the surrounding public facilities. , 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.

School installs jammers to block students from texting

SPOKANE, Wash. – Frustrated by the continued distraction of cell phone texts and calls, a Spokane school invested in a device to block phones from work.

The main reason for this is that students cannot focus on their work during class but spend a large part of their time using cell phones and therefore always look for a tool that can block cell phone signals so that students can concentrate on their class can concentrate. The cell phone jammer is a good choice, it can quickly block the phone signal, turn it off when not in use, and the phone can restore the signal.

Mobile Phone Jammer

Mt. Spokane spent less than $ 100 buying a cell phone jammer online and was just completing a three-day trial period aimed at frustrating students writing in class.

“We just thought it was something we wanted to evaluate,” said director John Hook.

The Mead School District is working with the FCC to determine if the device is legal before it can be used again.

The jamming device was switched on during class time and switched off during passing times and the lunch break.

“We believe there are times during the school day when parents need access to students and students need access to family members, doctors and the like,” Hook said.

But class time is not one of them. Student policy requires students to have cell phones if they are turned off and kept out of sight during class; but not everyone obeyed.
