phone shielding bags are a commonly used tool to block the transmission of electromagnetic signals such as mobile phone signals and Wi-Fi signals to protect personal privacy and information security. However, for ordinary users, how to verify the shielding effect of phone shielding bags is not an easy task.
- Use mobile phone signal test applications
- Perform a visual test
- Use Wi-Fi connection test
- Test based on actual conditions
- Professional equipment test
- Conclusion
Modern smartphones usually have a built-in signal test function that can help you quickly detect the signal strength of your mobile phone. You can download some mobile phone signal test applications in the app store, such as "Network Cell Info Lite", "OpenSignal", etc. Using these applications, you can test the signal strength of your mobile phone without a shielding bag, then put the mobile phone in the shielding bag and test the signal strength of the mobile phone again. By comparing the results of the two tests, you can preliminarily judge the shielding effect of the phone shielding bag.
Another simple method is to perform a visual test. Put the mobile phone in the shielding bag and then make a call or send a text message. Observe whether the mobile phone can successfully connect the call or send a text message. If the phone cannot make calls or send text messages in the shielding bag, the shielding bag may have a better shielding effect.
Wi-Fi signal is also a common electromagnetic signal, which can be used to verify the shielding effect of the phone shielding bag. Put the mobile phone in the shielding bag and try to connect to a Wi-Fi network. If the mobile phone cannot connect to the Wi-Fi network in the shielding bag, the shielding bag may have a better shielding effect.
In addition to the above methods, you can also test according to actual conditions. For example, when using the shielding bag, observe whether the mobile phone can still receive calls, text messages or notifications. You can also try to make Alipay payments, swipe bus cards, etc. when using the shielding bag to observe whether they can be carried out normally. These tests under actual conditions can more intuitively reflect the shielding effect of the phone shielding bag.
If you need more accurate test results, you can use professional test equipment for testing. Some professional institutions or laboratories may have corresponding equipment to accurately measure the shielding effect of phone shielding bags on signals of different frequency bands and different intensities. In this way, you can get more accurate test results.
The shielding effect of the phone shielding bag directly affects the effect and safety of its use. Through the methods introduced above, you can quickly and easily verify the shielding effect of the phone shielding bag, so as to choose a suitable shielding bag to protect personal privacy and information security. In addition to phone shielding bags, you can also choose cell phone jammers. When using phone shielding bags, it is recommended to choose products with reliable quality and obvious effects, and regularly check the use status of the shielding bag to ensure the stability of its shielding effect.
