The working principle of mobile phone signal jammers unite
1. Introduction to the principle of mobile communication: The working principle of the mobile phone is as follows: within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method.
2. Brief introduction to the principle of mobile cell phone jammer According to the above-mentioned communication principle, the mobile phone jammers unite scans from the low end frequency of the forward channel to the high end at a certain speed during the working process. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.
3. Basic functions: 1. Effectively shield mobile phones such as CDMA, GSM, PHS, etc. 2. Only shield mobile phone signals, without affecting the normal operation of other electronic equipment 3. Slow start design, it can work stably for a long time when the power is turned on.
We must first know the frequency range that the mobile phone jammers unite shields, and how it works, and then use a communication device that is not in the same frequency band. For example, the working frequency of a mobile phone is about 600-1800, and a mobile phone signal jammer is to shield frequencies above 500 (high frequency). If you use a relatively low frequency (low frequency) below 500, you can prevent it from being shielded.
