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.

If the ringing of a cell phone interrupts the speaker’s thinking at an important meeting, it will upset them and distract attendees from the meeting. The cellphone in the meeting room with important rings is rude behavior. Therefore, in many meetings, before the prompts begin, the phone will shut down or put into mute state. Many companies are not allowed to take cell phones with them while attending the meeting, visible on cell phones in the Internet age, the use of cell phones is regulated more and more clearly.

If you’re part of a conference, how do you feel when you hear your cell phone ring frequently during meetings? I think you will be as mad as I am, dissatisfied with this behavior, and even berate the owner of the phone. This is an unfortunate ending, not what we want to see. To avoid these unpleasant results, the conference room to use portable jammer is very important. There are many advantages to using in the meeting room, as you can see above, to prevent the uncivilized phenomenon from occurring. There is not only a ban on cell phone ring tones, but also a ban on cell phone use during the period.

If you’re a boss, you need to attend the meeting often. A cell phone rings or someone is looking at a cell phone in the meeting. Then you can prohibit the use of the cellphone by installing a cellphone signal jammer. It can now be bought in our store www.jammer-shop.com, which will make you more accessible and respected for the staff.

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.

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.

5G mobile phone signal jammer parameters

5G signaling is the hottest topic of the year, and the construction of 5G base stations across China has begun to implement 5G signal coverage. How convenient is it to use 5G signals? On the morning of May 10th, Hunan 5g Digital Industry Association and 5g + started the ceremony at Changsha Meishif International Cultural Arts Center, started the ceremony, Hunan Mobile and Xiang River, Hunan University, Xiang River Hospital, Banda Environment, Cool Wow Banda Partners have signed strategic agreements such as the establishment of a general 5g digital industry alliance to speed up the development of 5g application innovation. On the experience site, Revo, general manager of Hunan Mobile Changsha Branch, also passed the first 5G video call with Changsha City’s Tianxin District Committee standing member and Changsha City’s deputy director, State Shijun. .. We can think of how convenient 5G will bring to people.

As a new information technology infrastructure capable of providing at least 10 times the peak rate of 4g, transmission delays of millisecond, and billions of levels of connectivity, 5G is an automated driving, big health medicine, industrial internet, city of wisdom, Internet infrastructure for building things, high-definition video application scenarios to drive the Internet, big data fusion, artificial intelligence, and the depth of the real economy are critical to supporting high-quality development. is. It also brings about the rapid development of science and technology.

“3G, 4G, probably low and long wavelengths, at which high frequencies can resonate with some of the vibrational frequencies of water molecules and oxygen.” After the advent of 5G, future technological advances in 5G Not only do we need to enjoy the convenience and convenience, but we also need to pay attention to the effects of electromagnetic waves on the human body.

China Mobile and China Unicom have issued a license to use mid-low frequency test frequencies in 5G systems. Among them, China Telecom and China Unicom have obtained licenses for test frequencies in the 3500MHz band, and China Mobile has obtained licenses for test frequencies in the 2600MHz and 4900MHz bands. Therefore, it is safe to use 5g jammer within the range. China Unicom and China Tele have secured a more international mainstream spectrum, but the story of China Mobile is much more complicated. In terms of subdivision, China Mobile has acquired 5G test frequency resources in the bands 2515mhz-2675mhz and 4800mhz-4900mhz. Of these, 2515-2575mhz, 2635-2675mhz, and 48800-4900mhz bands have been newly added, and 2575 bands have been added. -2635mhz prioritized China Mobile’s existing td-lte (4G) frequency.

Do I have the right to ban the use of mobile phones during working hours?

Employers may limit employee rights and personal freedoms. However, that does not mean that it is possible to completely ban the use of mobile phones during working hours.

No, it is very dangerous to generally and absolutely ban the use of personal telephones.

Limitations must be justified by the nature of the task being performed and proportional to the purpose pursued (Labor Law, Art L.1121-1).

The rules of procedure cannot be justified by the nature of the task to be performed and cannot include restrictions proportional to the purpose pursued (Labor Law, Article L.1321-3).

However, for safety reasons, you may prohibit the use of the telephone while driving the device, handling dangerous products, or when there is a risk of interference with electronic devices. However, employees working alone in the office are prohibited from using their mobile phones. The phone doesn’t seem to be justified.

3G Mobile Phone Jammer

Using cell phone signal jammer can be annoying to other employees. Therefore, it should be used with caution. For example, you can set usage rules such as asking an employee to put the phone in vibrator mode or making a call outside the office.

Commission Nationale Informatiqueet Libertés (CNIL) authorizes use for personal purposes within the company, provided that the telephone and the Internet are of reasonable use.

Remember that employees fulfill their employment contracts in good faith. There needs to be a reason to use the phone. Don’t sacrifice work performance. In case of abuse, employees can be punished. You need to be able to prove abuse of your personal phone during working hours …

Mobile phone shielding device selection guide for examination rooms

By the annual exam season, all parties have begun to prepare for the exam, and the invigilator has various tricks to prevent high-tech fraud. Among them, the shielding device used in the examination room is still an anti-fraud shielding device. However, Chengdu Saiyue Communication reminds that there are many types of shielding devices, and users should clarify their needs before purchasing them to avoid test room accidents due to poor shielding effects, and pay attention to the correctness of the method of use.

First of all, I want to clarify the place of use. Most schools use test room-type mobile phone shields that are suitable for long-term work and are durable. The second is how big are we in the shielded area? For example, if it is a room of 100 square meters or a venue of thousands of square meters, if the area is large, the power must be larger, and if the area is small, the shielding power must be considered small. Then there is which frequency bands need to be shielded. Are all China Mobile, China Unicom, Telecom and CDMA shielded? Still only need to shield part of the frequency band.

Phone Wifi signal jammer

At this time, we remind everyone that if you want to buy a suitable shielding device to achieve the effect, it depends on the method used. The main points are as follows:

1. It is recommended that the indoor shielding device be placed at a height of about 180cm-220cm above the ground, with a forward angle.

2. Whether there are obstructions (such as walls, metal products, etc.) between the wireless jammer and wireless communication equipment (mobile phones, etc.). The interference signal emitted by the jammer will be attenuated to different degrees after passing through the obstruction, please try to avoid it.

3. The weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the shielding device.

4. The farther the jammer application environment is from the signal tower, the stronger the theoretical shielding effect of the jammer.

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.

Many authoritative units began to use mobile phone signal jammers

 

When the mobile phone works, it is within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission are completed with a certain baud rate and modulation method. In view of this communication principle, the cell phone signal jammer scans from the low end frequency of the forward channel to the high end at a certain speed during the working process. 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. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.

Common mobile phone signal jammers on the market have operating frequencies: 869~894MHz; 825~960MHz; 1805~1880MHz and 1900~1990MHz, etc. The operating frequency bands are CDMA800, GSM900, DCS1800, and PCS1900. It can control the range of about 40 meters in diameter, using DC-DC converter input voltage and 5V output voltage.

The emergence of mobile phone signal jammers has played a certain role in suppressing the increasingly serious “mobile phone noise pollution”. But as a mobile communication interference device, will the electromagnetic radiation generated by the A topic of concern. At the same time, during the installation and use of mobile phone shielding equipment, due to the greater autonomy and randomness in terms of the number of installed units, transmission power, coverage, and radiation control, some places require effective interference and The shielding effect is maximized, even blindly introducing high-power mobile phones to interfere with the installation and use of shielding equipment. The impact and damage to the human body cannot but be worrying.

As another product of human beings, the “mobile phone signal jammer”, while shielding mobile phone signals and ensuring information security, it will definitely bring a certain negative impact. However, when we look at the problem, we should see the main contradiction. Just as we did not stop using a kitchen knife because it cuts vegetables, we will not reject a “mobile phone signal jammer” because it may cause harmful radiation to the human body. After all, the “mobile phone jammer” guarantees information security and contributes to social stability is its main contribution. The most important thing is that it brings security to places with high safety factors such as prisons, detention centers, and major conferences.

As far as the quality of the mobile phone signal shielding system is concerned, judging by the current level of scientific understanding, there is no security problem. The reason for this is mainly based on the following two reasons:

First, from a technical point of view, although the mobile phone signal shielding system is a new technology product, it should be said that it has been developed more mature in technology, so it has high security. According to the test report of the authoritative testing organization, the qualified mobile phone signal shielding system has low radiation, and because it is usually installed in high places, it has no adverse effects on human health.

Second, from a practical level, many authoritative units in China have begun to use mobile phone signal shielding systems. For example, in 2004, in order to maintain the solemn atmosphere of the memorial hall and meet its special confidentiality requirements, the Chairman Mao Memorial Hall Administration installed a mobile phone signal shielding system produced by Shanghai Jike Electronics Co., Ltd. in the memorial hall. After actual use and testing , The Memorial Hall Administration believes that the products produced by Jike Company meet its requirements in all aspects including safety and aesthetics. I think this should be a very convincing case. In addition, according to the information collected by the author, as a leader in the mobile phone signal shielding system industry, the products produced by Shanghai Jike Electronics Co., Ltd. are used in the prisons of the judicial departments and the detention centers of the public security departments. All of them are used, and the feedback after use is believed to be a proof of immortality.

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 .

Cheap GPS jammers pose a major threat to drones

Jammers that can be bought for as little as $ 50 threaten commercial drones, but options exist.

With the rotors buzzing and the airframes racing through the air, drones can be very dangerous if flights don’t go as planned. Much has been gnawed about the FAA’s measured approach to implementing commercial drone guidelines, but the fact is there are real dangers, even from bad actors using inexpensive GPS jammer.

phone signal jammer

GPS signal jamming technology is evolving, decreasing in size and cost. These days jammers can be bought online for as little as $ 50. Jamming has long been a threat to military assets and is becoming a commercial problem today as commercial drone shipments become a reality and attacks become ubiquitous around the world. This threat now affects trade, law enforcement, and defense drones on critical missions.

During a choreographed light show in Hong Kong in 2018, 46 drones fell from the sky due to a jamming device. The resulting property damage and loss of hardware is estimated to cost an estimated HK $ 1 million. Almost all drones have security protocols that can be used to send them home or to a safe landing site in the event of a disruption. However, these functions were found to be ineffective at the Hong Kong show.

“These are professional-grade drones already built with technology that will guide them back to the launch site,” Anthony Lau Chun-hon, director of the events committee, told the South China Morning Post. “But the signals were so strong that many of them just fell out of thin air.”

Drones and their services are decidedly dependent on GPS signals. Although the drone may have backup methods (INS / OPS), GPS references are still required for positioning, navigation and stabilization. GPS attacks are therefore the easiest way to shut down a drone and potentially cause harm to life and property.

The good news is that solutions for drones are arriving with commercial quality and coming straight from the defense sector. One comes from a company called infiniDome, which makes a device called a GPSdome that is built into a drone’s GNSS receivers and uses a unique interference filter system that combines the patterns of two omnidirectional antennas. GPSdome analyzes the interference signal in real time and feeds its properties into infiniDome’s proprietary algorithm to filter and reject attacking RF interference, so that the UAS continues to rely on GPS signals during a jamming attack. If an interference signal is detected, the GPSdome notifies the operator of possible signal interference.

Easy Aerial, a leading provider of autonomous, drone-based surveillance solutions for commercial, government and defense applications, recently added GPSdome to its range of autonomous unmanned aerial systems for military use.

“We chose GPSdome because it was a proven solution that was a perfect fit for the various missions our customers routinely fly in some of the most inhospitable and hostile environments in the world,” said Ido Gur, Co-Founder and CEO of Easy Aerial. “While our systems have multiple redundancies on board, GPS signals for maintaining position, navigation and timing accuracy are critical to ensure uninterrupted operation.”

This type of lightweight, small form factor, low power shielding technology is a critical step towards widespread adoption of commercial drones. Other companies like Sepentrio also take GPS interference in drone applications with integrated sensor solutions seriously.

It is certain that the problem of GPS interference and spoofing will receive more attention in the coming days. Fortunately, developers seem to be beginning to see tools that they can use to counter the growing threat.
