Does the full-band signal jammer interfere with the base station?

Will the full-band signal jammer interfere with the base station?

The full-band signal jammer is a commonly used device that can generate interference signals to shield communication signals. However, it will also bring some interference effects to the surrounding mobile operator base stations. When using a low-power jammer, its transmission power is relatively small, which limits the distance of the interference signal and minimizes the interference to the mobile phone base station. In this case, a certain degree of use is tolerable. However, if customers purchase and use a high-power full-band signal jammer that uses the traditional white noise high-power suppression method, the mobile communication base station at a closer distance may be significantly affected by interference.

As a manufacturer that has focused on high-power full-band signal jammers for nearly two decades, JAMMERSIGNAL understands this problem and has implemented relevant technical measures to ensure that our high-power jammers do not interfere with base stations. In terms of RF interference, the main concern is the interference of the uplink frequency band of the base station. Historically, mobile phone base station signals are divided by frequency, separating the uplink and downlink frequency bands. Signal jammers mainly interfere with the downlink frequency band of the base station and generally do not interfere with the uplink frequency band. Therefore, unless there are inferior product manufacturers who fail to accurately adjust the interference signal to the downlink frequency band range, the impact of interference can be effectively avoided.

However, with the continuous advancement and widespread application of mobile communication technology, the introduction of the TDD (time division duplex) standard has made this problem more complicated. The TDD system adopts the time division duplex mode, which does not distinguish between the uplink and downlink frequency bands within a fixed frequency range, and uses the bandwidth of the entire frequency band, with time as the division standard, that is, processing uplink signals in a specific time period and processing downlink signals in subsequent time periods. Since this mobile phone frequency band system does not distinguish between uplink and downlink, when a full-band Cell Phone Jammer is used for interference, the traditional continuous white noise interference method will inevitably cause interference in the uplink time period.

How to solve the base station interference problem?

The solution is relatively simple. It is mainly to synchronize the base station signal with the time slot of the base station processing uplink and downlink signals through the synchronization module that receives the base station signal. After synchronization, the interference signal of the full-band signal jammer can only be transmitted during the time period when the base station processes downlink data, perfectly avoiding the time period when the base station processes uplink data, and avoiding interference with communications and base stations.
