How is the mobile phone Jammer device that does not interfere with base stations achieved?

How can a mobile phone jammer not interfere with base stations?

It is a common consensus in the industry that the use of mobile phone jammers will cause interference to the base stations of communication operators. This interference is mainly due to the limited transmission power of low-power Cell Phone Jammers, which leads to limited transmission distance. The interference to the base station can be tolerated when used by a small number of users. However, if high-power mobile phone jammers are purchased and used by some customer units, the conventional white noise high-power interference suppression method will cause interference to the communication base station at a closer distance.

As a manufacturer specializing in the production of high-power mobile phone jammers for nearly 20 years, we have the technical means to ensure that high-power jammers do not interfere with base stations.

how can a mobile phone jammer not interfere with base stations?

It is not difficult to solve the problem of base station interference. Generally, the interference to base stations is mainly aimed at the uplink frequency band. In the past, mobile phone base station signals were divided into two frequency bands, uplink and downlink. Mobile phone jammers mainly interfere with the downlink frequency band of the base station. Unless some inferior product manufacturers cannot accurately adjust the interference signal to the downlink frequency band range, it generally does not interfere with the uplink frequency band of the base station. However, with the rise and widespread adoption of the mobile phone time division duplex (TDD) standard, the working method of this standard does not distinguish between uplink and downlink frequency bands, but divides the frequency band bandwidth by time, processing uplink signals in one time period and downlink signals in the next time period. Since the mobile phone frequency band system does not distinguish between uplink and downlink frequency bands, when our mobile phone signal jammer interferes with this frequency band, the traditional continuous white noise interference method will inevitably cause signal interference in the uplink time period.

Since TDD is a time division duplex mode, the solution is very simple. The mobile phone shielding device synchronizes with the base station time slot through the synchronization module that receives the base station signal, so as to process the uplink and downlink signals accordingly. After synchronization, the interference signal of the mobile phone shielding device is only transmitted during the time period when the base station processes the downlink data, which effectively avoids interference when the base station processes the uplink data. In this way, the communication base station is no longer affected by the interference of the mobile phone shielding device.
