1. Understand the concept of interference strength
Before evaluating the interference strength of a mobile signal jammer, you first need to understand what interference strength is. Interference strength refers to the degree of influence of the electromagnetic waves emitted by the cell phone jammer on the mobile phone signal. The greater the interference strength, the more severe the interference to the mobile phone signal and the worse the communication quality.
2. Use a signal strength tester
A signal strength tester is a device specifically used to measure the signal strength of a mobile phone, which can help evaluate the interference strength of a mobile signal jammer.
| Choose a suitable signal strength tester | Make sure the frequency range of the tester covers the target frequency band, such as 2G, 3G, 4G, and 5G. |
| Set tester parameters | Set the frequency range and scanning mode of the tester as needed. |
| Measure the signal strength of the mobile phone | Without turning on the jammer, use a signal strength tester to measure the signal strength of the mobile phone and record the results. |
| Turn on the jammer | Turn on the jammer and use the signal strength tester to measure the signal strength of the mobile phone again. |
| Compare the results | Compare the signal strength when the jammer is turned on with the signal strength when the jammer is not turned on. If the signal strength drops significantly after turning on the jammer, it means that the interference strength of the jammer is large. |
3. Observe the communication quality
In addition to using a signal strength tester, you can also evaluate the interference strength of the jammer by observing the communication quality of the mobile phone.
- Observe the mobile phone signal icon: Without turning on the jammer, observe the signal icon on the mobile phone screen and record the signal strength.
- Turn on the jammer: After turning on the jammer, observe the signal icon on the mobile phone screen again.
- Compare the results: Compare the signal icon when the jammer is turned on with the signal icon when the jammer is not turned on. If the signal icon shows weak or no signal after turning on the jammer, it means that the interference strength of the jammer is large.
4. Observe the communication stability
In addition to signal strength, the interference strength of the jammer can also be evaluated by observing the stability of communication. If the interference intensity of the jammer is high, the communication may become unstable, disconnected or the call quality may deteriorate.
5. Use signal analysis software
Signal analysis software is a software tool used to analyze mobile phone signals and can help evaluate the interference intensity of the jammer.
