Is the mobile jammer interfering with the base station?
The widespread use of mobile jammers can cause certain interference to the base stations of mobile operators, which is a widely recognized reality in the industry. If it is a low-power jammer, due to its relatively small transmission power and limited distance of interference signal transmission, its interference impact on mobile base stations can still be tolerated in a small number of cases. However, if certain customer units purchase and use high-power mobile jammers, and their interference modules still use the conventional white noise high-power suppression method, then communication base stations with close proximity will not be disturbed!
However, as a professional manufacturer of high-power mobile jammers for nearly 20 years, Nanjing Baikang Electromechanical Technology Co., Ltd. has relevant technical means to ensure that our high-power interference equipment does not interfere with the base station.
It is not difficult to solve the problem of base station interference, as the interference to the base station is mainly focused on the uplink frequency band of the base station. In the past, the base station signals of mobile phones were divided into uplink and downlink frequency bands based on frequency, while mobile jammers mainly interfered with the downlink frequency band of the base station. Unless it is a manufacturer of some inferior products that cannot precisely adjust the interference signal within the range of the downlink frequency band, it generally does not cause interference to the uplink frequency band of the base station. However, with the rise, promotion, and popularization of the TDD system for mobile phones, this system adopts a time division duplex working mode, which is within a fixed frequency range and does not distinguish between uplink and downlink frequency bands. It uses the bandwidth of the entire frequency band and uses time as the dividing standard, that is, processing uplink signals in one time period and processing downlink signals in the next time period. It is precisely because of this mobile phone frequency band system that does not distinguish between uplink and downlink, when our mobile jammer conducts signal interference against this frequency band, it will inevitably generate signal interference in the uplink period by using the conventional continuous white noise interference.
Since the working mode of TDD is time division duplex, the solution is easy to implement, which is to synchronize it with the time slots of the base station for processing uplink and downlink signals through a synchronization module that receives the base station signal. Once synchronized, the interference signal of the mobile jammer is only emitted during the time period during which the base station processes downstream data. This perfectly avoids the time period during which the base station processes upstream data, and therefore no longer interferes with the communication base station.
