Cell Phone Jammers are devices designed to block cellular signals in a specific area. They find applications in various settings, such as prisons, theaters, and examination halls, where the use of mobile phones is prohibited. This article provides a step-by-step guide on the installation and testing of Cell Phone Jammers, ensuring effective signal blocking within the desired range.
1. Preparing the Installation:
Before installing a Cell Phone Jammer, it is crucial to determine the optimal placement. Typically, the jammer is positioned in the front and rear corners of the area where it will be used. This ensures maximum coverage and effectiveness.
2. Testing the Signal Blocking Range:
To test the signal blocking range, three mobile phones from different network operators should be placed diagonally across the usage area, farthest from the jammer. Allow the phones to remain idle for approximately 2 minutes without any user interaction. Check if the phone screens display “No Signal.” If so, it indicates successful signal blocking. Conversely, if the phones show signal strength, attempt to make a call or access the internet using the network provider’s hotline or mobile data. If successful, move the phones closer to the jammer and repeat the process until the phones are completely blocked, unable to make calls or access data. This determines the effective signal blocking range and helps determine the number of jammers required for the area.

3. Addressing Strong Signal Areas:
In cases where the Cell Phone Jammer’s low power is insufficient to block the entire usage area due to strong signal strength, a targeted interference approach can be employed. Identify the signal frequency bands that the jammer fails to block and use high-power blocking modules specifically designed for those frequencies. To determine the frequencies, download the Cellular-Z mobile app on an Android device. With the jammer activated, open the app and capture a screenshot. Share this screenshot with the jammer supplier’s technical team, who can identify the frequencies that the jammer cannot block.
4. Implementing High-Power Blocking Modules:
Finally, to cover the strong signal frequencies, high-power blocking modules can be used. These modules are designed to interfere with the identified frequencies effectively, ensuring comprehensive signal blocking within the usage area.
Installing and testing Cell Phone Jammers requires careful consideration of placement and thorough testing to ensure optimal signal blocking. By following the steps outlined in this guide, users can determine the appropriate number of jammers required and address any strong signal areas effectively. Cell Phone Jammers play a vital role in maintaining privacy and security in various environments where the use of mobile phones is prohibited.
