Considerations for Configuring Cell Phone Jammers in Examination Rooms

Factors to Consider for Effective Signal Jamming in Different Examination Room Environments

Cell Phone Jammers are essential tools for maintaining a controlled testing environment in examination rooms. However, the configuration of these jammers should be carefully considered based on the size of the room and the surrounding environment. This article discusses the factors to consider when configuring Cell Phone Jammers in examination rooms, ensuring effective signal jamming and preventing signal leakage.

Room Size and Configuration:

Firstly, it is crucial to determine the number of examination rooms and their respective sizes. Conventional examination rooms are typically around 70 square meters. Based on past experience, one Cell Phone Jammer is sufficient for each of these rooms. However, for larger spaces such as lecture halls, conference rooms, or driving theory examination rooms, which can reach 200-300 square meters, it is recommended to configure at least two signal jammers to ensure comprehensive coverage.

Surrounding Environment:

Secondly, the surrounding environment of the examination room, particularly the distribution of mobile network base stations operated by telecommunication companies, should be carefully assessed. If there are base stations within a 300-meter radius of the examination room, special attention should be given when selecting signal jammers. In such cases, relying on a single jammer for a 70-square-meter examination room may result in incomplete signal blocking. It is advisable to conduct on-site inspections by technical personnel from the manufacturer to determine the proximity and signal strength of nearby base stations.

Indoor Signal Amplifiers:

Additionally, it is important to consider the presence of indoor signal amplifiers within the building where the examination room is located, typically in corridors or hallways. In such scenarios, two situations should be distinguished. Firstly, it should be determined whether the indoor signal amplifier can be temporarily disabled when using the Cell Phone Jammer. If this is possible, there is no need for further consideration. Alternatively, for cases where the amplifier cannot be turned off, it may be necessary to implement multi-module coverage for specific frequency bands.

Conclusion:

Configuring Cell Phone Jammers in examination rooms requires careful consideration of factors such as room size, surrounding base stations, and indoor signal amplifiers. By following these guidelines, educational institutions can ensure effective signal jamming, maintaining a controlled testing environment free from unauthorized mobile communication.
