dojammer signal blocker

 During the college entrance examination, the school will turn on the wireless  wifi signal jammer , which will damage the call quality of customers around the examination room, such as: frequent call failures, disconnection, loss, occasional voice chat, slow Internet, etc., which will return to normal after the examination. In addition, in order to ensure smooth signals near the school, the operator has arranged in advance for communication engineers to test the entrances and exits of each examination point and the lounge for parents who send their children to the examination, and to expand the hardware and software of the surrounding communication base stations to ensure that high traffic and high flow can be guaranteed during the test period. In addition to the data signal WiFi room being blocked, everyone tries to ensure that your communication is smooth. As we know, every year in the college entrance examination, in order to prevent cheating in the examination, all commun...

 Cracking method 1: Enter the cell phone settings, click "Network Settings", change the network mode to "Manual Model" and then enter "Online Search". Principle: The work of the cell phone starts within a certain frequency range. The  cell phone signal blocker  can only block the phone signal without affecting other nearby electronic devices; save power, the power is 12W-480W. It is also called cell phone signal blocker, cell phone signal blocker, phone jammer, signal jammer, cell phone blocker, signal obstruction device, cell phone signal isolator, signal isolator, cell phone signal interceptor, radio signal blocker, etc. according to its function. In order to solve the information security problem during the examination process, many examination halls usually use cell phone signal blockers and conduct external signal interference within a certain range in some ordinary high schools. How does the blocker interfere with mobile phone signals? Simply put, th...

 Nowadays, there are many areas around us that are strictly prohibiting the use of mobile phones, especially those places with information security requirements such as examination sites, corporate offices, classrooms, factories, companies, etc. In the past, in addition to putting mobile phones in the signal shielding cabinets of the security department in advance, these areas can also install mobile phone signal blockers. Cell phone signals can appear in different places, everywhere, such as Wi-Fi signals and other signals exist everywhere, so installing a  cell phone signal blocker  can effectively block them. Without a mobile base station, the mobile phone will not be able to receive information. At this time, you are less likely to have the mentality of playing with your mobile phone, and you can quickly improve your personal skills and achieve your desired goals. The emergence of mobile phones has provided a very good communication tool for the general public, which ...

 Recently, many users have consulted us about  cell phone signal jammers , but these customers generally only tell us the coverage range they need and the price they can afford. However, when we communicate technical issues and recommend actual products to customers, customers are often surprised by the price. What is the situation? In fact, it is very simple that customers do not understand the relationship between the transmission power and coverage range of mobile phone signal jammers. The demand often stated is a very large coverage area, but this requires the use of high-power cell phone signal jammers to solve the use standards, but the price that the psychological budget can afford can only buy low-power mobile phone signal jammers, but they don’t know that in the signal jamming industry, the price difference between high-power and low-power products is quite large, and it is not a little thing at all. So the question is, how to distinguish the emissivity of mobile phon...

 Mobile phone signal blockers are mainly used in various examination venues, schools, gas stations, churches, courts, libraries, conference centers (rooms), cinemas, hospitals, government departments, financial institutions, prisons, public security agencies, defense key areas and other places where mobile phones are strictly prohibited. According to statistics, the cell phone signal blockers on the market today can block mobile phone signals 500 meters away from the tower. The signal blocking radius can be adjusted automatically, and the coverage area can reach more than 30 square meters. The output power of the  cell phone signal blocker  is generally 12W--480W. Can cell phone signal blockers block Wi-Fi numbers? High-power cell phone signal blockers can not only block mobile phone signals, but also effectively block Wi-Fi signals, GPS signals, and Beidou satellite signals. Among them, since the output power of Wi-Fi and WLAN signals is in the range of 2.4GHZ or 5.8GHZ,...

 Use high-power  5G jammers  to achieve high power gain in the room There are many online shopping malls selling signal jammers, such as cell phone signal jammers, GPS mobile phone signal callback functions, Wi-Fi signal blockers, UHF signal jammers, and other types of signal blockers. But now we rarely find a full-featured signal blocker that can block 5G signals and is suitable for indoor use, with strong sound spacing. If you need to get this kind of signal blocker, you can come here and get one you like. Since many 5G cell phone signal blockers can block 5G mobile phone signals, of course we can't see the details of the high-power 5G jammers used in all rooms. The best way is to take an example and then look at the details of the 3G4G5GWimax signal callback function used in this room. Its full name is "70W high-power 3G4G5GWimax mobile phone signal". Soon you will know that this high-power signal blocker design has 5 antennas and this high-power jammer design is dedic...

 There are three categories of GPS jammers: (1).  GPS jammer , which blocks satellite signals (which, in turn, creates noise in communication satellite frequencies). The signal is always transmitted to equipment located on the road (or above) at two key frequencies: the GPS frequency (civilian L1 frequency band used to locate trackers) is 1575.42MHz. Frequency GLONASS (civilian L1 frequency band, used to locate trackers): 1602MHz. Because the frequencies are so close, they are blocked by broadband network noise generators, requiring only a wireless antenna. (2) GSM jammer, which will have an impact on communication operators. Operators work under different rates, which actually lies in the mode (3G, 4G) and standard (GSM, DAMPS, CDMA). This way, many wireless antennas can be combined onto a single blocking device, thus shutting down all the wireless antennas so they can be separated. (3) Universal jammer. It applies to all frequency bands, such as communication operators and s...
