 Within a certain frequency range, the mobile phone and the base station are specifically connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The jammer scans from the low-end frequency of the forward channel to the high end at a certain speed during operation. 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 and achieve the purpose of shielding the mobile phone signal. The mobile phone appears to search the network, no signal, No service system, etc. In layman's terms: When the mobile phone signal jammer is working, it will send out the Frequency jammer to interfere with the downlink signal of its base station. If the power of the jammer is greater than the power of the local base station signal, then the mobile phone will have no signal. If the power of the jammer is less than the local The power of the base station signal will be signaled by the mobile phone. |
