Mobile phone signal jammer is also called mobile phone signal blocker and blocker, it can block the mobile phone signal, so that the mobile network can not normal communication, so as to achieve the purpose of interference, it only blocks the mobile phone signal, the other electronic equipment is no impact, then the use of mobile phone signal jammer should pay attention to what? Let me give you a detailed introduction.
1, when we use the mobile phone signal jammer, if we want to realize the interference of the jammer for the mobile network, we need to ensure that the signal field strength sent by the jammer is far higher than the field strength of the mobile signal in the jamming area, and the closer the jamming site is to the base station, the stronger the field strength is, so the effective interference area will be smaller.
2. In the process of working, the mobile phone signal jammer should scan from the low-end frequency of the forward channel to the high-end at a certain speed, and the scanning speed can form garbled interference in the received message signal of the mobile phone, so that the mobile phone can not detect the normal data sent from the base station, so that it can not effectively connect with the base station. There is no signal, no service system, no search network search.
3, if you want to understand how the mobile phone signal jammer works, you need to first understand the principle of mobile communication, it is in a certain frequency range, let the base station and mobile phone through radio waves to contact, and a certain baud rate and modulation mode, to complete the transmission of sound and data. When the mobile phone is communicating, the contact with the base station is carried out through the uplink frequency, and then the signal is transferred to the mobile service switching center, so that the call can be achieved.
The above introduces the problems to pay attention to the use of mobile phone signal jammer, the use of mobile phone signal jammer is very simple, which is to ensure that the sent signal field strength is large, otherwise it can not have a good shielding effect.
