Cell phone jammers can keep cell phone signals reasonably

At present, all mobile phones on the market are digital wireless signals, and the anti-interference ability of digital wireless signals is very strong. If the analog signal scheme is used to interfere with digital wireless signals, the actual effect is very poor. Therefore, digital signals must be used to interfere with digital wireless signals. Compared with the same power level, the digital signal and the analog interference signal have very different effects. The shielding device using the digital signal interference technology is lower in power than the shielding device using the analog signal interference technology, and the efficiency can be improved more. In addition to the mobile cell phone jammer that can affect the data signal, the signal shielding cabinet on the mobile phone can also have the effect of affecting the data signal. Mobile phone signal jammers can reasonably suppress cell phone access. The alarm system is leaked, and it can be stored on several mobile phones at a time, and standardized management on the mobile phones of government agencies, troops, conference halls, examination rooms and other confidential places.

Generally speaking, shielding the outgoing frequencies during work affects all normal frequencies on the mobile phone receiving the communication base station, making the mobile phone unable to connect with the communication base station, and thus unable to answer calls, receive short messages, and go online normally. When the mobile phone signal jammer is turned on, although the data signal is full on the mobile phone, in fact, the signal is not good in the whole process of application. When the signal shielding on the mobile phone is turned on, it only has the actual effect of shielding the mobile phone, and other electronic products are not harmful. This is due to the detailed electromagnetic induction data signal outgoing by the signal shielding on the mobile phone. In the medium frequency band for collection work stipulated by the state, only the communication on the mobile phone can be blocked. The moon data signal has been in a relatively static state, and it is not easy to manufacture all electronic products.
