A mysterious shadow that has been active in many examination rooms recently. I believe that many people still don’t know its true identity. It is a good partner that has been vigorously developed in campus size tests and can effectively prevent fraud - Cell phone signal jammer.
Now is the time for the college entrance examination, and many universities are looking for a batch of mobile phone signal jammers with better performance to ensure relatively stable examination room discipline during the college entrance examination.
But many people don't know that there is one thing that may affect the actual effect of the mobile phone signal jammer. This is also an issue that must be considered at the examination room level. It is a base station, because the birth of the base station will affect the effect of the mobile phone signal jammer, but this means that within 500 meters near the examination room, if it is 500 meters away, it will not have an impact. The reason for the impact is that the base station itself contains a strong electromagnetic field. The height of the electromagnetic field will affect the shielding effect of the mobile phone signal jammer. Therefore, when funds are put into use at the examination room level, it may be practical to apply, query the number of specific shielding categories, and then based on the specific information Determining the number of mobile phone signal jammers requires great attention, otherwise some places will not be blocked. But regardless of whether the cell phone signal jammer will be affected, a more functional and more professional cell phone signal jammer is necessary.
In recent years, communication technology has developed rapidly. The products of various Internet companies have been updated many times, from the original 2G network to the current 3G, 4G, and all the way to the 5G data signal Internet. At the same time, the signal jammers in the examination room are also constantly changing. The upgrade has been updated and exchanged for many generations now.
In the past ten years or so, it has become common for schools to purchase and install cell phone signal jammers, but most schools only use them as anti-cheating safeguards during the examination process, and only in some of the more important types of examinations. It will only be used in high school, such as the annual high school entrance examination, college entrance examination, or the CET-4 and CET-6 exams of college English. It can be seen that the utilization rate is actually relatively low, so the problem is that the mobile phone signal jamming equipment that the school has spent a lot of money and great efforts to build is not only used for anti-cheating in exams, but also in the expanded application of school teaching management. No? If so, what extensions can be included?
First of all, if the school selects the online version of the mobile phone signal shielding terminal with intelligent networking function when selecting the initial product type and formulating the mobile phone signal jammer project plan, the result is that the school can fully utilize the potential of such mobile phone signal jamming equipment play out.

The online version of the signal blocker has obvious advantages over the stand-alone version of the mobile phone signal jammer. The stand-alone version has no networking function and cannot realize intelligent centralized control and management. If it is necessary to expand the functional application, the solution is to first complete the networking work through the external networked controller.
Once the intelligent mobile phone signal interference equipment completes the networking work, the school administrators can conduct centralized control and management on the remote main control software. The main control software can communicate with the school’s teaching management software platform. The easier function is that it can be synchronized with the school bell. For example, when the class bell rings, the mobile phone signal interference device will be turned on synchronously. The interfering instruments are then turned off synchronously, so that the work of the system can be operated in a humanized manner, and this system can be used to maintain classroom order and prevent students from secretly using mobile phones during class and not concentrating on studying.
The school can also be freely grouped according to each grade or each building, each floor, etc., can group different areas in the school, and carry out signal shielding by area, all of which can be carried out on the main control software of the mobile phone signal interference instrument Edit and set.
If the school installs the mobile phone signal jamming device in the dormitory area of the students, then the timing function of the main control software can be used to automatically turn on the shielding system when the students go to bed at night. After the students fall asleep normally, or the mobile phone signal jamming device is set It will automatically shut down after 2-3 hours of scheduled operation. This can ensure that students will not be obsessed with mobile games and chatting on the Internet after the lights are turned off, so that they can fall asleep peacefully to get enough sleep time and maintain strong learning energy!
In order to improve user perception and satisfaction, the mobile company has taken various measures to solve the problem of radio interference: one is to set up a quick complaint channel and set up a dedicated complaint hotline to ensure the problems are reported to users will be solved in the first time. The second is to increase publicity and education, and create posters and individual pages with complaints about radio interference and related requirements for investigation and handling, and post them in residential areas and group units to remind users that the cessation of Using security camera wifi jammers and repeaters without permission is a crime and may violate criminal law. , If the general public often encounter abnormal mobile phone signal or WIFI signal, please report to the operator in time. The third is to coordinate with multiple parties and establish a smooth coordination mechanism with the Radio Management Committee and the Public Security Bureau to ensure that operators, non-delegated committees and public security bureaus conduct investigations and deal with radio transmissions affecting the disturb citizens. normal life and order, and crack down on them. Jammer Able to block 5 frequency bands simultaneously, this powerful remote control jammer is popular now.
While there is no cell phone jammer to block the data signal, it is very likely that other safer and more environmentally friendly inspection methods are being used. Therefore, it is better to express these ideas more appropriately. Before decoding cell phone jammer data signal, you need to know its basic principle: jammer security camera According to the shielding style, it is divided into omnidirectional and fixed type. The omnidirectional type is an olive type, and the fixed type is an olive type. Sector type, i.e. omnidirectional cell phone jammers have a larger shielding area than fixed type cell phone jammers.
GPS is widely used in military affairs, science, automobile positioning, mobile phone positioning, etc. GPS and electronic map can display the actual position of the vehicle in real time, and can arbitrarily zoom in, zoom out, restore and change the image. You can keep the target on the screen as the target moves; you can also achieve multi-window, multi-vehicle, multi-screen tracking. This feature can be used to track and transport important vehicles and goods. GPS satellite positioning and navigation technology is extremely convenient for our exercise. It can predict the best route for us in advance, making our travel time shorter. The best route can save our time and improve our safety on the road. efficiency. GPS satellite positioning signal technology is likely to expose our whereabouts at the same time. It is precisely because of the use that criminals will install GPS trackers on our vehicles, so that we can see his whereabouts at all times, no matter where we are place. In order to prevent this kind of device tracking, the GPS satellite signal jamming frequency device was born, which shields the satellite signal so that these tracking devices cannot work normally and send our location information to criminals. As the number of stalking incidents increased, more and more dignitaries and individuals of state purchased GPS jammers that they would carry with them and turn on when they needed protection. The equipment is easily available on the Internet and sold all over the world with high quality, multi-signal spectrum and competitive price. It is extremely effective in protecting the privacy of device whereabouts.

With the rapid development of technology, WiFi signals are everywhere. Streets, restaurants, libraries, stations, shops, and home WiFi networks are almost all covered, even toilets, buses, etc. It can be said that it will appear wherever you need it. The popularity of WiFi networks provides an infrastructure for people to use their mobile phones, computers and other devices that can access the Internet. They can watch videos, stream live sports and play games on the WiFi network without worrying about additional data costs. We all know how expensive mobile phone data charges were in the past, but with the coverage of WiFi networks, operators have taken measures to reduce data charges in order to compete for customers. As long as there is a WiFi network, people still use the WiFi signal more, and the signal is strong and the speed is fast, which is beyond doubt. But have you ever thought about WiFi security? Many mobile phones now have anti-virus software such as Security Manager, which will tell you whether the current WiFi is safe, which is a way to protect your information. But is it reliable? I have no idea. With the development of science and technology, more and more lawbreakers carry out criminal activities such as stealing personal accounts and property through network fraud. Many of them rely on WiFi networks, and they can learn your information through WiFi, and then realize the theft. Do you find it scary? Faced with this situation, the best way is to use a WiFi jammer, which is divided into many types, including handheld and portable, and home desktop. If you want to protect the WiFi security at home, you can buy a home wifi blocking device jammer , this function is more powerful.
GSM-based technologies are used in practically every country in the world. The Australian Communications and Media Authority (ACMA) banned jamming of radio communication devices (including mobile phones) in 2011. This electromagnetic interference is the reason certain places such as airports and gas stations and hospitals require cell phones to be turned off. Many mobile phone blocking technologies are found in software or apps GSM jammers are installed.
In contrast, CDMA is currently used in fewer than 10 countries. In 2014, the agency fined a Florida man $48,000 for using one in his car to discourage nearby drivers from using their phones on the road, according to availability fools you. GSM offers a somewhat limited data transfer rate. At the very least, one might think that the sacred space of a church would be safe from compulsive lyricists, but in late 2014 a priest in Naples, Italy, having such trouble with cellphones buzzing during sermons, installed a cell phone jammer.

When you find that the mobile phone has no signal, everyone should not sit still, but conduct the appropriate search, go through the correct method, and then learn how to prevent. Finding the reason why something happened is the premise of a better solution, so everyone must take it seriously when they come across it and not be careless. There is no way to solve natural problems. To prevent 88, you need to understand various aspects and then pay more attention to yourself. When getting things done, everyone will always involve a lot of things. If you specifically pay attention to these practical aspects, you can understand connections better, and then a lot is guaranteed in the future. In doing so, everyone should properly perform some inspections and pay attention to more information so that they know how to prevent these problems. Usually, they should pay more attention to related situations and solve problems. It will of course be beneficial. When you encounter these problems, you must also understand the position. These are actually very important.
Some areas that need strict control, such as military bases, prisons, detention centers, etc. have a very high level of confidentiality and should be strictly controlled by mobile phones. In military areas, prisons, detention centers and other areas, cell phone signal blocking can greatly prevent the possibility of leaks. Fairness and fairness are the basic principles of society and there are many trials in life ranging from junior high school entrance exams, high school entrance exams, college entrance exams and civil service entrance exams. In order to prevent candidates from cheating on various large and medium-sized exams, the signals in the exam room must be shielded by other technical means to meet the needs of mobile phone communication and Internet access can also be excellent prevention. The concealment practices of the candidates. While mobile phones have all their benefits, they can also be very harmful and cause a lot of trouble. That is why we would like to introduce the 88 to you. With this powerful machine, you and your secret information are safe. Because cell phone GPS jammers try to block phone signals within a certain radius.
