Solutions to Address Mobile Signal Interference in Chinese Universities


Mobile signal interference has become a significant issue in Chinese universities due to the presence of base stations and indoor signal amplifiers. The limited capacity of these devices, coupled with the large number of students and staff on campus, necessitates the installation of such equipment. This article explores potential solutions to mitigate mobile signal interference during important exams, such as the English proficiency tests (CET-4 and CET-6), by either negotiating with the service providers or utilizing high-power signal jammers.

Subheading 1: Negotiating with Service Providers

To address the issue of mobile signal interference during exams, it is crucial to confirm the presence of base stations and indoor signal amplifiers on campus. Once confirmed, the university administration can contact the service providers responsible for these devices. Negotiations can be initiated to temporarily switch off the power supply to the base stations and indoor signal amplifiers during the exam hours. This will result in a decrease in mobile signal strength within the teaching buildings, thereby enhancing the effectiveness of Cell Phone Jammers.

Subheading 2: Utilizing High-Power Signal Jammers

Another solution to combat mobile signal interference is to employ high-power signal jammers. These devices can significantly improve the interference effect to a certain extent. However, it is important to note that this method incurs higher costs and cannot guarantee complete interference of mobile signals in the entire examination hall without adjusting the base stations or indoor signal amplifiers on campus.

Subheading 3: Targeted Interference with Professional Testing

To overcome the limitations of low-power signal jammers, a professional on-site testing can be conducted to identify frequency bands that are not covered by these devices. Subsequently, high-power interference modules corresponding to the identified frequency bands can be selected for targeted interference. This approach reduces costs compared to the second method, but it requires specialized expertise and consideration of whether the university is willing to incur additional expenses.


Mobile signal interference during exams in Chinese universities can be effectively addressed through negotiations with service providers to temporarily disable base stations and indoor signal amplifiers. Alternatively, the use of high-power signal jammers or targeted interference with professional testing can also mitigate the issue. However, each solution has its own advantages and limitations, and the university administration must carefully evaluate the feasibility and cost-effectiveness of these options. By implementing appropriate measures, universities can ensure a fair and uninterrupted examination environment for students.
