Mobile phone jammer is a device that prevents the transmission or reception of signals by transmitting the same radio waves as mobile phones. It is designed to help people solve various problems related to mobile phones, radio signals and wireless connections. Candidates are accustomed to using some high-tech cheating tools during exams. This is unfair, and it is difficult for the teacher to detect with naked eyes. Therefore, some test centers turn on the cell phone jammer during the exam to prevent the mobile phone signal transmission from the root cause, thereby preventing cheating in the exam.

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.

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 …

To accurately determine the scope of your rights in disciplinary matters, Tissot Editions advises the document “Tissot Social Enterprises” whose complete file is dedicated to “Disciplinary and Disciplinary Procedures”.

What should I do if I am tracked by cell phone signals?

China now has a lot of cell phone signal jammer, but what would happen if China did not have a mobile phone signal booster? Most of the mobile phone signal booster technology is not up to standard, resulting in a serious decline in the overall signal quality of many urban villages. It is because of this type of equipment that the mobile phone signal amplifier products are notorious. The actual data interferes with the base station and affects the neighbors’ equipment. It is just that people have a habit of doing well. If there is a problem, it will be spread.

Although the mobile phone signal amplifier has produced many negative effects, the positive effects are even greater. In my basement, there is no signal to solve by myself. Your own company has just been renovated, and you can solve it yourself if the signal is not enough. Any environment where the signal cannot be resolved in time can be resolved with an amplifier.

Principle of signal isolator

In the industrial production process, a variety of instruments and meters are used in the monitoring and control of the generation process, which will generate a variety of signals: both faint small signals of millivolt level and tens of volts Large signals, even strong signals up to thousands of volts and hundreds of amperes; there are DC low-frequency signals, high-frequency or pulse spike signals; and these signals have to go through the process of mutual transmission and transmission, so how to ensure these signals In particular, the non-distortion of analog signals during transmission will become a problem that must be solved in system debugging.

Specifically, only when the analog signal transmission between the control device and the sensors and actuators distributed in the field is fault-free and undistorted, can the process control be safe and reliable. Especially low-power analog signals are affected by various external interference signals when they are transmitted in an industrial environment with high interference, and they need a reliable transmission channel. Daily work experience shows that due to equipment requirements, analog signals must be handled and transmitted carefully. However, the measurement and control parameters transmitted in the form of analog signals between the field and the control layer are often in a harsh industrial environment in the transmission project, which is likely to cause distortion of these signals.

Second, the principle of signal jammer

At present, the signal isolator (converter) is mainly divided into several kinds of isolation methods: transformer isolation method, photoelectric isolation method and transformer and photoelectric joint isolation method.

Signal isolators have a history of more than 40 years. Early signal isolators used transformer isolation. Its characteristics are: stable performance, long life, strong load capacity, high isolation strength, but the circuit is complex, and the manufacturing process requires higher.

With the development of electronic technology, in recent years, optoelectronic isolators produced by optical couplers have gradually appeared. Its characteristics are: stable performance, strong anti-interference ability, simple wiring and low cost, but compared to The transformer isolation method has a slightly shorter life.

In some occasions where the interference is large and the process requirements are high, the signal isolator of the combination of transformer and photoelectricity appears, and its isolation ability, resistance to unlimited radio frequency and electromagnetic interference is stronger.

Cell phone jammers set the time online

Most lawyers believe that schools can at least prohibit the use of cell phones under certain conditions and circumstances. However, this must be done within an appropriate framework. On the other hand, a ban that goes beyond this scope and prohibits the wearing of cell phones only is largely viewed as unacceptable. First of all, it is widely believed that schools cannot make their own rules at will. You must provide a legal basis for this and follow the principle of proportionality. The school laws of the federal states form this basis, but most of them only have general requirements: the schools can specify measures for the fulfillment of educational and teaching tasks in the school regulations. This can also include restricting cell phone use. This is a common quarrel between related employees: To what extent can a cell phone signal jammer be used to ban cell phones, and what happens if it is violated? Since the ban on the use of mobile phones can also affect the basic rights of students, such as B. Free personal development and property rights, it must be proportionate. In addition, parents may have legal rights so that they must also be taken into account when contacting their children via mobile phones. It has to be proportional. In addition, parents may have legal rights so that they must also be taken into account when contacting their children via mobile phones. It has to be proportional. In addition, parents can have legitimate rights and interests, so that interest must also be taken into account when contacting their children via mobile phones.

4G Mobile Signal Jammer

At the moment, the obvious trend towards the lawyers’ control over the use of mobile phones is barely discernible: For example, the Baden-Württemberg Ministry of Education considers it sensible to ban the use of mobile phones during breaks. However, as long as individual regulations can be formulated appropriately according to educational requirements, this depends on the school.

Special Circumstances for Formal Exams: Wearing cell phones may be prohibited and formal exams are usually more stringent. For this reason, students are usually required to leave their cell phones at the teacher’s desk or elsewhere, and the cell phones they carry can be viewed as a sham. This also depends on the personal circumstances and the detailed provisions of the school and examination regulations as well as the federal school laws. For schools, “primary evidence” may be enough to deceive others. This means that the school can try to deceive if the student’s behavior shows typical characteristics. If the student does not agree, he has to prove that his case is atypical – that is, even if the case appears to be true, he has not deceived.

According to a ruling by the Karlsruhe Administrative Court, it is generally sufficient to have a mobile phone with you so that the inspection can be classified as “unsatisfactory”. If the inspection regulations provide for such consequences for “unauthorized aids”, they apply in any case. In one specific dispute, a student left his cell phone in his room handbag during an oral exam. However, since the school did not clearly indicate the prohibition again prior to the specific inspection, the subsequent rating of “unsatisfactory” for the specific situation was disproportionate. The school had to change the grades again. If there was a cell phone jammer at that point, we could get the same effect without checking the cell phone.

Bavaria has a special state law. In 2006 the school banned the use of cell phones. Pupils must switch off their cell phones “in school buildings” unless they are used “for teaching purposes”, the teacher makes an exception (Article 56 of the Bavarian Education Act). Other federal states have special regulations for schools.

Mobile jammers confuse operators and manufacturers

The unwanted ringing of telephones in the middle of a movie or concert, soon more than a bad memory? Industry Minister Patrick Devedjian definitely hopes that. On October 10th, it issued an order authorizing the installation of “cell phone blocker” to disable cell phones in theaters and cinemas.

This ends more than three years of floating. Because the law of July 17, 2001 (which establishes various provisions of a social, educational and cultural nature) “allows” this type of disturbance “both for emission and reception (…) in the enclosure of the theater. The regulator for Telecommunications then issued a decision to “establish, at a technical level, the regulatory requirements for the use of these devices.” This decision, which was sent to the Ministry of Industry in late June 2003, had to be approved before it could be applied.

This is what Patrick Devedjian has just done, concerned about the “catastrophic impact” mobile ringtones could have “on the revenues [of the cinema operators] and therefore on the film’s bottom line,” he added. he explained on the France Info microphone. Installing such filtering or jamming devices will be the responsibility of cinemas, theaters and concerts, he said. Remember that since September 9, 2002, the Judiciary Orientation and Programming Act also authorizes GSM jammers in prisons.

The icing on the cake for cinemas
In a press release, however, the minister recalled two principles that power halls and manufacturers are obliged to adhere to. On the one hand, “jammers must not cause the success rate of calls outside the room to deteriorate.” On the other hand, their “location must not stand in the way of the application of the regulations applicable to emergency calls”.

This measure enthused Jean Labbé, President of the National Federation of French Cinemas. At France Info’s Airwaves, he welcomed this decree, which “is the result of a long request [from] extremely diverse cinemas, ranging from large to small exploitation”. For him, “the jammer approval is icing on the cake” after efforts and investments have been made to improve the comfort of the rooms.

Others are far from sharing this enthusiasm. “It is a radical decision,” one of the three mobile operators told ZDNet. “These cuts can create security issues and urgent objections.” In 2001 all operators had unsuccessfully applied for the withdrawal of this measure during the ART consultation on this issue.

Challenge from Brussels and several EU countries
Same story at Orange: “Good communication is enough to curb the problems of good manners in theaters,” said a spokesman. As evidence, he said: While the number of cellphone-equipped customers has doubled in a few years, inappropriate behavior has not necessarily increased.

The operator is highlighting the “Citizens’ Campaign” that has been running for several months with posters to encourage customers to switch off their cell phones or let them vibrate on trains or in cinemas. And is concerned about possible overflows from these filter devices: “Who knows if this won’t cause problems with the neighbors upstairs or with people on the street?” Asks the Orange spokesman. France.

Henri Asenkat, President of the Association of Manufacturers and Industrial Companies for Cellular and Professional Radio Communications (Acirp *), also reiterates his opposition to the process. “We had long conversations with ART to explain to them that we are not cheap because of the ethics of the manufacturers who want us to network,” he said.

“We also claim that this is against European regulations.” In 2001, these manufacturers tried to convince ART that this provision violated several European directives (**) with no result. Despite several detailed comments from the UK, Denmark, Finland and the Commission itself contesting the jamming principle, the regulator sent its decision to the Department of Industry in June 2003.

What is a GPS jammer? Are GPS jammers generally used in cars?

The GPS signal jamming system is designed to suppress the signal of the global satellite navigation GPS system in the range of 1500-1600MHz. The jammer makes it impossible for GPS satellites to monitor the location of cars and all vehicles through GPS, and the GPS jammer device will not interfere with mobile phones and other devices. Gps jammers can range from 5 to 15 meters, which is sufficient for cars and trucks and buses, because the tracker is usually installed in the cab inside the car. After starting the connection through the car cigarette lighter, the device immediately starts to work and generates radio noise (interference) in the range of 1500-1600 MHz (L1/L2) within a 15-meter radius.

GPS equipment will need a phone card. The current location information calculated by the GPS module is uploaded from the communication base station to the positioning server through this card for users to query, and the jammer uses wireless electromagnetic waves to interfere with the communication between the card and the communication base station to achieve The purpose of GPS location cannot be queried by the user.

Working principle of GPS jammer:

Mainly by releasing radio interference waves, the GPS locator can be invalidated within the designated electromagnetic wave band, forming the same electromagnetic environment as the equipment used to block the signal.

There are two ways to shield GPS signals. First: The direct is to remove the two wires of the GPS host. Second: Go to the electronics market to buy a GPS signal jammer, but you must first distinguish what signal tracking method the GPS on your car uses.

There are only two ways of signal tracking: (1) Cell phone signal. (2) Direct satellite tracking signal.

Generally, most GPS tracking signals use mobile phone signals. GPS jammers have the same interference effect on car navigation. GPS used for car navigation is the same as mobile phone signals. It is easily interfered by electronic devices. The signals are shielded, so that all communication devices in the range lose their signals. However, such equipment also has disadvantages for the users. The signal jammer can only be turned on temporarily, and it is impossible to open it forever. As long as he turns off the jammer, the GPS will have the signal again.

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.
