With the emergence and popularity of mobile phones, their functions have become more and more perfect, and our lives have become more intelligent and modern. Smartphones have become an important tool in our lives, and they bring us great convenience in communication, social and information storage. We store personal photos, account information and some important files in our mobile phones, so the smartphone contains a lot of important information. This has caused many hackers to attack our smartphones to get our important information and achieve their illegal purposes.
Security researchers have found that hackers are more willing to attack smartphones than computers. Your smartphone stores all of your important information. The data security of your smartphone is more vulnerable to hackers. You can find that our mobile phone has serious security risks by comparing the security index of the Android system and iOS system. It has become very necessary to use cell phone jammers to make your phone data more secure.
With the advancement of science and technology, our smartphones have greatly improved their security, but they are not absolutely safe. There are still many insecure factors. These factors can easily become hackers, attack our smartphones, and never acquire them. A tool for your important information. This is also an important factor in the need to use mobile phone jammers to protect our private information.
The mobile phone signal shielding device is also called mobile phone blocker. It is used for the uplink and downlink channels of the mobile phone system, and uses the techniques of frequency multiplication, frequency division and frequency hopping filtering to analyze the required shielding frequency. A spherical shielding is customized according to the power of the shielding device. Space, automatically forming a shielding magnetic field within the specified range, invalidating the mobile phone in this space. When the shield is in working state, the function of transmitting and receiving signals of the mobile phone within the specified range is invalid, and it is impossible to dial out and dial in, thereby achieving the purpose of mandatory disabling.
Cell phone jammers are mainly used in various examination rooms, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, hospitals, government, finance, prisons, public security, military heavy places and other places where mobile phones are prohibited. When the cell phone signal blocker works, it can only block the cell phone signal without affecting other electronic devices.However, in densely populated areas such as schools, it is forbidden to set up radio stations with excessive electromagnetic radiation, and mobile phone signal shielding devices must not be used without authorization.
When using: Select the area where you need to cut off the signal of the mobile phone, place the disconnector on the desktop or wall in this area; after the installation is complete, turn on the power of the disconnector and turn on the power switch; after the device is connected, press the power switch to cut off the device. Then it work. At this time, all the mobile phones that are turned on in the field are in the search network state, and the base station signal is lost. The main callee cannot establish a call.
