How to test the shielding range of mobile phone signal jammer
The following methods are usually used to test the effective shielding range of a mobile phone signal jammer:
1. On-site testing of multiple mobile phones: Use multiple mobile phones of different operators and different standards (including 2G, 3G, 4G, 5G, etc.) for on-site testing. After turning on the jammer, test from near to far from the installation position. It is recommended to test in multiple directions.
2. Signal detection: Don’t just check the signal grid number on the mobile phone, because the signal grid number is sometimes inaccurate. You should try to make a casual phone call, such as a local toll-free number or a fixed landline number. If the call fails, it means it is still within the blocking range.
3. Static test: Hold each test point for more than half a minute to confirm whether the phone is blocked. Dynamic detection during a call is not recommended.
4. Consideration of environmental factors: When testing, you should pay attention to whether there are base stations around, because environmental factors have a significant impact on the shielding effect.
5. Evaluation of test results: After testing multiple frequency bands, select the distance with the shortest shielding radius as the effective shielding radius of the jammer in this area.
6. Professional equipment testing: If you have professional equipment, such as a spectrum analyzer, you can directly conduct on-site testing to obtain more accurate data.
7. Compliance inspection of regulations and standards: Ensure that the signal jammer for sale complies with relevant regulations and standards, such as DB45/T2588-2022 "Technical Specification for Evaluation of Mobile Communication Signal Interference Protection Effectiveness in Confidential Scenarios", etc.
8. Third-party testing agency: You can contact a professional third-party testing agency for testing to obtain an authoritative testing report.
The above method can help users accurately evaluate the effective shielding range of mobile phone signal jammers. When conducting testing, ensure that relevant regulations are followed and are conducted under professional guidance.
