What kind of signal jammer is good for the conference room

As we all know, the conference room is a very serious place and cannot be affected by the external environment. For example, corporate strategy meetings, public institution department meetings, public security, prosecutorial and judicial department meetings and other government department meetings. The progress of the meeting has a great impact. At this time, a mobile phone signal jammer is needed, and a mobile phone signal jammer is arranged in the meeting room to shield the mobile phone signal. The mobile phone has no signal and naturally cannot communicate with the outside world.

But how to choose a cell phone signal jammer device, Shenzhou Mingda company provides you with high-quality mobile phone signal shielding solutions:

1. According to the size of the meeting room. For example, the model of shielding device used in a meeting room of 100 square meters and 200 square meters is completely different.

2. According to the usage time of mobile phone signal jammer in the meeting room. According to our conventional understanding, if the frequency and time of use of the signal jammer is 5 hours a week, commercial machines can be used at a relatively low price. If the signal jammer is used for more than 20 hours a week, use an industrial machine, which is relatively expensive.

3. According to the intensity of the field signal used by the signal jammer. In the category of conference rooms, it is not easy to judge. We usually judge based on the absence of signal amplifiers in the office, whether there is an operator base station within 300 meters, and the signal strength of the usual mobile phone. If the mobile phone signal is strong, you need to use it. A slightly larger power shield.

In short, the purpose of the mobile phone signal jammer to shield the mobile phone signal is a comprehensive factor, including the consideration factors listed above.

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.

In the era of technology, we need to protect personal privacy

GPS positioning brings a lot of convenience. However, if you do not notice, GPS will quietly display your personal information. The ubiquitous GPS positioning of mobile phones and personal electronic devices continues to determine your whereabouts. In addition, some smart phone applications will also open the location function and display your whereabouts. Therefore, a reliable GPS jammer is needed to maintain personal information security and protect privacy.

Basically, GPS tracking is mainly performed by the vehicle, so it is particularly important to select a gps signal jammer specific to the vehicle.

mini signal gps jammer

GPS jammers can effectively block satellite signals, track GPS satellite positioning, and protect your privacy and personal information. In view of the characteristics of all current GPS satellite positioning systems, use this product to effectively explore GPS satellite signals within 2-15 meters to form an effective protection area, so that your whereabouts will not worry about being tracked.

Most GPS jammers are built for military purposes. The purpose is to take the enemy to their exact location or where the enemy drops GPS-guided missiles or bombs. However, there are some civilian uses that interfere with GPS signals, including the ability to hide yourself or your vehicle when the GPS receiver is tracking yourself or your vehicle.

Although GPS jammers have been developed (especially by governments, military organizations, and spy or privacy gadget companies), most civilians do not yet have the technology to create their own homemade devices. This is much more difficult than using basic radio interference to block radio signals.

Example of installation of UAV countermeasure equipment by cultural relics protection unit

UAV “black flying” harm

There are blind spots in the supervision of drones in my country, and the large-scale use of drones brings hidden dangers to public safety. Drones that were originally used for legal purposes are increasingly being used for criminal purposes. The public has become increasingly aware of the harm that drones may cause. UAVs can smuggle drugs; UAVs can spy on privacy/technology; UAVs can affect civil aviation – close to collisions; UAVs may appear in sensitive areas, key locations, cultural heritage protection units and government facilities; UAVs may even Can shoot automatically…

Because the intrusion of drones has brought great harm to everyone’s lives, many units have begun to install drone countermeasures. Let’s take a look at this fixed drone counter independently developed by Texin Electronics. Control the efficiency of the equipment.

On September 20, 2019, Shenzhen Texin Electronics installed a set of fixed drone signal jammer in the cultural relics protection unit of Zunyi City, Guizhou. The interference range of the current frequency hopping aircraft on the market is more than 1 km, and the interference frequency band controls 2.4G and 5.8. G is positioned at 1.5G to achieve the effect of driving away the forced landing. The 1.5km drone cannot fly into the cultural relic unit.

Detention center mobile phone signal jammer solution

In order to meet the needs of the new situation, improve the scientific and technological prevention capabilities of the detention center, strengthen the scientific and technological management level of the detention center, promote the construction of digital information detention center, promote the harmonious and stable development of the detention center, and continuously improve the modernization level of the detention center work, it is necessary to scientifically and effectively monitor the mobile phone signals in the detention center. Control and prevent the hidden dangers caused by illegal use of mobile phones.

The establishment of a cell phone signal shielding system in the detention center complies with the relevant regulations of the Ministry of Justice and the spirit of the document. At the same time, it also has an urgent need. During the implementation of the mobile phone signal shielding system in the detention center, the shielding of the internal area of ​​the building should take into account the distance between the residents (schools) and other public facilities in the area where the building is located, and also refer to the distance and signal strength of the surrounding communication rack base stations. Affect the normal communication of mobile phone signals in surrounding public facilities for network shielding.

22 Antennas Wireless Signal Jammer

At the same time, the requirement for full coverage and shielding of mobile phone signals within the detention center should also be considered. Outdoor high power jammer can be used for inward coverage of wall coverings to ensure the shielding of mobile phone signals in all areas. At the same time, it is aimed at possible blind spots in the detention center building , The missing point is used to repair the mobile phone signal jammer, so as to give full play to the product performance and greatly improve the jammer effect.

How to know the shielding range of indoor mobile phone signal jammer?

Many customers call and say that I need a cell phone signal jammer that can shield a radius of 50 meters, an interval of 500 meters, and a radius of one kilometer. It also needs to be shielded by China Mobile, China Unicom and China Telecom. Is there a problem with the customer’s request? No problem, and a specific interval requirement is given, but can it be completed? The answer is that it is more difficult to achieve. Why is it more difficult to achieve? Isn’t the signal jammer’s parameters marked with its own shielding interval, can it be done if you put a few more units according to this interval? In fact, it is not the case, the customer is not wrong, but they don’t know the signal jammer The shielding plan is not a fixed value. How to understand it? Texin Electronics will give you an explanation.

The signal jammer scans the low-end frequency to the high-end of the channel at a certain speed during the operation process. This scanning speed can constitute garbled interference in the message signal received by the mobile phone, causing the mobile phone to fail to detect the normal microwave signal data announced from the base station , Make the mobile phone unable to establish the connection with the base station within a certain plan, to achieve the purpose of shielding the mobile phone signal.

high power signal jammer

Simply speaking, the frequency announced by the mobile phone signal jammer disturbs the mobile phone to receive the frequency of the base station. The jammer and the base station are destined to be a competition connection. If the transmission power of the signal jammer is less than the channel that the base station transmits to the mobile phone in the environment at that time Power, then the jammer will not be able to shield, only the power of the signal jammer is greater than the power delivered by the base station to the mobile phone in order to effectively shield. Therefore, any shielding device used in different signal environments will show different shielding intervals, and mobile, China Unicom and telecommunications will be different, because the base station density, base station orientation and base station power built by these three operators cannot be the same of.

In other words, how many meters the mobile phone signal jammer can shield is not only related to its own transmission power, but also to the distance between the base stations in the use environment (base stations are not limited to large-scale transmission towers built on the ground, but also buildings. The signal expansion antenna on the top and the signal expansion and dispersion made in some buildings), another important factor is obstacles, if it is a metal material, it will directly block; if it is a solid wall of reinforced concrete, it will be less attenuated after penetration 10 times; if it is wood board or glass material, the attenuation after penetration is relatively small.

So next time there are customers who say how many meters apart they need to be shielded, they must ask about the distance between the base stations in the environment, and whether they are used indoors or outdoors, whether they need to penetrate walls, etc. Customers can contact us to learn about the use of signal jammers. Only by understanding these can they better choose the appropriate signal jammer for customers.

Devices that force mobile phones to silence

As cell phone use in public places has soared, making it impossible to endure listening to mid-conversation, a small but growing band of rebels is turning to a slightly drastic solution: the mobile phone jammer, a device which completely cancels the signal transmission of all mobile phones.

GPS cell phone blocker

Jammer technology is not entirely new, jammer exporters from overseas say the demand for jammer devices is increasing every day and they are sending more than 100 a month to the United States – prompting a close scrutiny of the matter by the federal controller and raising the interest of the telephone industries. Consumers include owners of coffee shops and hairdressers, hotels, theater operators, bus drivers and, increasingly, commuters.

The development is igniting a battle for airspace control, within earshot. And the damage will have a side effect. The insensitive chatterers impose their noise on the defenseless who are therefore forced to endure all the noise in silence. While the jammers punish not only the person responsible for the noise, but also the one who talks on the phone in a confidential way.

“If there is one thing that characterizes the 21st century, it is surely our inability to control ourselves for the benefit of others,” said James Katz, director of the Rutgers University Mobile Communications Studies Center. “The one who talks on the phone thinks his rights outweigh those of everyone else around him, while the one who carries the jammer in his pocket thinks his rights are more important.”

Wireless jammer technology works by emitting radio signals so powerful that cell phones are, therefore, canceled and are no longer able to communicate with cell phone towers. The range of action of a jammer varies from a few centimeters to several meters, and the devices cost from $ 50 to several hundred dollars. The larger devices can be left on to create a real off-limit zone for mobile phones.

wifi blocker device

The use of jammers is deemed illegal on American soil. The radio frequencies used by telephone users are protected, just as are the frequencies used by radio and television broadcasters.

The Federal Communications Commission argues that people who use jammer devices can be fined up to $ 11,000 for just the first offense. The Commission’s enforcement office has sued a handful of American companies, found guilty of supplying the devices – and not only that, but also the one who uses the jammers.

“Investigators from the Commission and Verizon Wireless visited a well-known upscale restaurant in Maryland last year,” says the owner, who refuses to disclose the name, and confesses to buying a jammer for $ 1,000. because he was tired of seeing his employees with their eyes on their phones rather than on customers.

“I told them: put away your phones, put them away, now” but they ignored him.

The owner said that Commission investigators stayed for about a week, looking for jammers using special equipment. But the owner had already turned them off.

The work of the Verizon investigator, as well as that of the Commission, proved fruitless. “Yes he went to anyone in the city and gave them his number, saying to warn him immediately, in case they had difficulty making calls” claimed the owner, who reveals, since that moment, that he has stopped using the jammer.

The emergence of jammers makes cars safer

Coaches are another important example of trackers installed in cars. Some truck drivers provide temporary information to customers so that customers can check the location of the truck and better take care of the cargo. Customers can log into the site and check the location of the truck as it can reach the destination in real time. This reduces or eliminates the update information of the location of the truck driver. Truck drivers can also benefit from the fact that customers know when they are coming and are ready to ship. In addition, a tracking device is installed on the long-distance truck, and the safety of the cargo can also be known. If the truck is hijacked, the location of the truck can be known based on the tracking, then the cargo can be stored.

The 5G cellular standard has a data rate of 10 gigabits per second, strong network reliability, and precise positioning accuracy. Knowledge of positioning is a basic requirement for many new markets, so positioning is considered to be one of the important components of 5G mobile network system design. The cellular industry is implementing a long-term evolution, which can be called the evolution of old ordinary LTE and the combination of “real 4G” mobile broadband. The demand for new mobile communication systems is increasing and there is a need to further improve the signal function of the network, which is the future fifth generation (5G) cellular network system. Experts say 5G can handle communications 10 times faster than 4G. Enough to download 3D movies within 30 seconds from 5G network. The current 4G network will take at least six minutes.

The mobile phone is a great tool of invention, whether for work or people’s life, but it is always exposed to such things, which inevitably leads people to misunderstand it. Is this situation in your family? Does your child stay up all night with a cell phone? If so, I suggest you purchase a mobile phone jammer to avoid this behavior. It is not a healthy lifestyle. On the one hand, the main goal of children is to learn and not to spend all their energy on the Internet. On the other hand, the physical and mental development of children is not healthy, and excessive use of cell phones will affect their healthy growth.
