precisejammers

　　In recent years, with the rapid development of mobile phones, it is not uncommon for students to use mobile phones to affect their life and learning. Some students often use their mobile phones to surf the Internet in bed, and some even use their mobile phones to surf the Internet in the middle of the night. It is still one or two o'clock, so in order to prevent students from playing mobile phones in the middle of the night and give themselves a better rest, many schools have to choose to install wifi jammer in their dormitories.

　　So is it enough to put a high-power mobile phone jammer? Is every room in the school dormitory like a school exam room? Actually, how to select and install it is explained below. The cell phone signal jammer gps in the school dormitory are mainly used at noon and evening when students are resting. Noon is generally 12:00 to 1:30, and evening is 11:30. until 3 am. That is to say, there is no need to shield the mobile phone signal 24 hours a day, so the shielding device of the ordinary power supply such as the external adapter is also optional.

　　The wifi jammer gps can be big or small, and there are many channels in any frequency band of mobile communication. They are technically channels, and both channels can be used as BCH. For example, in the case of masking, there is uncertainty even in some cells.

　　The scope of cell phone signal jammers is limited to classrooms and dormitories. Obviously, the school's behavior is mild and does not affect students' freedom of communication and expression. The exercise of any right is limited and must not prejudice the rights of others or the public interest. The freedom of communication and speech that citizens enjoy in accordance with the Constitution and the law shall not exceed their due scope.

　　Test the effect of wireless signal jammer

　　When American College Test uses a wireless signal jammer, the installation is a very important content. If the control is appropriate, it is basically certain that there will be a very good shielding effect. However, if there is a problem in the deployment and control, it is easy to have a blind corner of the shielding, so the effect of the shielding is greatly reduced.

　　Speaking of which, the reason why American College Test installed a wireless signal blocker is actually to block the signal of the mobile phone, so at this time, we only need to use the mobile phone for testing and there is no problem. However, in this process, there are some points that need to be paid attention to. First of all, we need to prepare enough mobile phones. Because the frequency of each

　　mobile phone is slightly different nowadays, the inspection can only be completed by ensuring that each type of mobile phone is blocked. Secondly, the mobile phones we use should also be comprehensive in terms of operators. The mobile phones we will use every day, AT&T, Verizon, and T-Mobile mobile phones should be prepared for testing to ensure that everything is safe.

　　In addition to preparing a sufficient number of mobile phones, we also need professional help when testing. Many people may think that the detection is to see if the mobile phone has a signal, and we can do it ourselves. However, after the wireless signal jammer is installed, the impact range is very large, and many parts may have blind spots for shielding. It is obviously unrealistic for us to try one by one. professional staff will know which corners are prone to blocking dead corners because of their rich experience, so that they can effectively prevent loopholes during detection, and the overall efficiency will be higher.

　　Finally, when you are testing the mobile phone of the mobile signal jammer, don't think that the shielding has been completed when the number of mobile phone signals has completely disappeared. In fact, in many cases, the mobile phone has no signal grid number but still can transmit information. At this time, it is best to take intermittent calls to determine whether the phone is really blocked.

　　Mortgage car has also become a kind of automobile consumption. Some tens of thousands of Dollars have bought luxury cars such as Land Rover, Mercedes-Benz, and BMW. Why? Of course it's because of the affordable mortgage car.

　　The original car owner mortgaged his luxury car at a low price because he needed money urgently. If the capital turnover still does not exceed the deadline, he will lose the ownership of the car. Mortgage agencies ultimately want money, not physical objects, so they all choose to sell the car. As a result, consumers who buy a mortgage car have the opportunity to buy a luxury car at a low price.

　　Of course, buying a mortgage car also has risks. In addition to lack of understanding of whether the original car has failed or had an accident before, the biggest problem is worrying that the car is equipped with a tracker or locator. If you buy it back to your home, the original owner will find it and drive it away secretly, and turn on the mini gps jammer. Isn't it a big loss?

　　In the same way, after getting the owner's vehicle, the mortgage agency will also worry that the owner will find a parking place and quietly drive the car away.

　　How to solve this problem?

　　When the GpS jammer is installed on the vehicle and it is turned on, it will cut off the signal sent by the tracker hidden on the vehicle, so that others cannot locate the vehicle and cannot find the specific location of the vehicle.

　　In addition, the GpS signal blocker has the difference between a handheld small and a plug-in large, both of which can block mobile phone signals jamming wifi and GpS signals.

　　There is a growing demand for cell phone jammers in the market. The most common one is the cell phone jammer system that appears in various exams, including the American College Test and civil service exams, where the popularity of wireless signal shielding is often noticed. and effect. In order to achieve fairness in exams, mobile phone signal jammers are now selected to block the signal in the exam room during most exams around the world.

　　In order to strictly prevent candidates from cheating using high-tech electronic devices such as mobile phones, it is decided to no longer tolerate the behavior of criminals using radio equipment to cheat during the American College Test. The radio emergency command network and new radio monitoring equipment will conduct radio supervision on the American College Test throughout the process.

　　Some test rooms will be equipped with cell phone jammers for the first time to ensure that there is no communication signal in the test room. In the previous simulated American College Test radio cheating site, the technicians of the joint security team dispatched a mobile radio monitoring vehicle to monitor the examination room and its surrounding areas, to find the location of the interference source of the cheaters, and to monitor whether there were any suspicious signals. After finding the suspected cheating signal, the technicians will start the radio intelligent monitoring and warning system to technically block it, and at the same time use the portable radio monitoring equipment to locate the signal jammer device, so as to quickly find the cheating criminals.

　　"Once the surrounding geography is complex and it is difficult to find the signal source in a short period of time, the intelligent monitoring and warning system can take various measures such as voice suppression, interference signal suppression, and background noise suppression for cheating signal sources, so that candidates in the examination room cannot hear the examination room. The answer is transmitted from outside to the test room to ensure the fairness and impartiality of the test in the shortest time." This application of cell phone jammer can be described as a very successful.

　　The successful completion of the college entrance examination is inseparable from the high-quality anti-cheating tool-cell phone jammer.

　　If the mobile signal jammer is installed in an outdoor environment, it must take waterproof and lightning protection measures. Generally, it is

　　recommended to select a special installation box for the cell phone signal jammer. The louvered ventilation position (enhanced heat dissipation), the

　　opening on the top of the box extends out of the antenna of the mobile phone shield (the hole is sealed with hot melt adhesive), and the bottom of the

　　box has a power input hole and a diversion hole (to prevent water accumulation).

　　When the mobile phone signal jammer (together with the installation box) is installed outdoors, such as installed on the outer wall of the building,

　　it is necessary to take lightning protection measures. Especially in thunderstorm-prone areas, you should pay more attention!

　　The main unit of the mobile phone signal jammer is installed on the top of the box, the antenna extends out of the box (if it does not extend out of

　　the box, the shielding effect will be greatly reduced), and the power adapter should be placed in the middle and lower part of the box.

　　Lightning protection measures are actually to install lightning rods on the shielding device. If there is no ready-made lightning rod to buy, you can

　　make your own lightning rod. The method is as follows:

　　Choose 3-4 steel bars with a diameter of 5-10mm and a length of 50cm, sharpen one end into a needle shape, and weld the other end together to form a

　　"Y" shape. The welded end is connected to the ground with an iron wire with a diameter of 2-3mm (The iron wire is protected by PVC pipe penetration), and

　　the end of the iron wire to the ground is connected with an iron strip. The iron strip is generally about 50-100cm long and 2-5cm wide, and is deeply

　　driven into the ground. If the iron strips are hard to find, you can use 10mm steel bars instead.

　　The lightning rod is installed 30-50cm above the antenna of the mobile phone signal jammer. The lightning rod (including the grounded steel wire)

　　cannot be in contact with the mobile phone jammer or the installation box, and the distance should be properly maintained.
