Does the full-band signal jammer interfere with the base station?
The full-band signal jammer is a widely used device. It can generate interference signals to shield communication signals, but at the same time, it will have a certain interference effect on the surrounding mobile operator base stations. If a low-power jammer is used, its transmission power is relatively small, the distance of the interference signal transmission is limited, the interference effect on the mobile phone base station is small, and a certain degree of usage can be tolerated. However, if some customer units purchase and use high-power full-band signal jammers, and their interference modules still adopt the conventional white noise high-power suppression method, then the mobile communication base stations with relatively close surrounding distances will be affected by non-negligible Interfering effects.
Dojammer, as a manufacturer specializing in the production of high-power full-band signal jammers for nearly two decades, we understand this problem and have adopted relevant technical means to ensure that our high-power jammers do not interfere with the base station. For the radio frequency interference problem, the main prevention is the interference in the uplink frequency band of the base station. The reason why mobile phone base station signals are divided according to frequency in the past is to separate the uplink frequency band from the downlink frequency band, but the signal jammer mainly interferes with the downlink frequency band of the base station, and generally does not interfere with the uplink frequency band of the base station Therefore, unless the manufacturers of some inferior products cannot accurately adjust the interference signal within the range of the downlink frequency band, the impact of interference can be effectively avoided.
However, with the continuous upgrading and popularization of mobile communication technology, the introduction of TDD standard also makes this problem more complicated. Since the TDD system adopts the working mode of time division duplex, it does not distinguish between uplink and downlink frequency bands within a fixed frequency range. It uses the bandwidth of the entire frequency band and uses time as the division standard, that is, processing within a time period Uplink signal, downlink signal will be processed in the next time period. This mobile phone frequency band system does not distinguish between uplink and downlink, so that when the full-band signal jammer is used for signal interference, the conventional continuous white noise interference method will inevitably cause signal interference in the uplink time period.
How to solve the problem of base station interference? In fact, it is not difficult to implement. The main thing is to use a synchronization module that receives the base station signal to synchronize it with the time slot for processing the uplink and downlink signals of the base station. Once synchronized, the interference signal of the full-band signal jammer can only be transmitted during the time period when the base station is processing downlink data, which perfectly avoids the time period when the base station is processing uplink data, so it will no longer interfere with communication. The base station produces interference effects.
