The main function of the mobile phone signal jammer is to interfere with various 2G, 3G, 4G, 5G and other signals of the mobile phone. Within the range of its effective interference radius, all the mobile phones will behave as follows: the mobile phone shows no signal and cannot make calls. Or answer calls, cannot send or receive short messages, cannot use data traffic to access external networks, and so on. In addition to these direct performance results. In fact, some mobile phone signal jammers will also interfere with the base station to a certain extent. The question arises: which frequency bands are the interference to the base station mainly aimed at? Is there a way to eliminate this interference?

There are actually several types of mobile phone base stations of operators, which are divided according to the working frequency bands of each mobile phone system. Among them, the working frequency band of TDD-LTE is obviously different from that of other mobile phone systems. The TDD-LTE standard is a time-division duplex working mode. In the frequency band assigned to TDD-LTE, there is no dedicated frequency band for uplink signals and downlink signals. That is, in this frequency range, the base station is processing data services. , using the time division method, one time period is dedicated to processing uplink signals, and the next time period is dedicated to processing downlink signals. Since TDD-LTE has no frequency band distinction between uplink signals and downlink signals, this leads to the fact that mobile phone signal jammers can only cover the entire frequency band indiscriminately when interfering with the TDD-LTE frequency band.

When the mobile phone signal jammer is turned on, the nearby base stations will receive a certain degree of interference. If there are not many jammers at the same time, the interference to the base station will not be too great, but if dozens or even hundreds of jammers work at the same time, the base station will not be able to bear it.
