The distance between the base station is too close and the shielding distance of the mobile phone signal jammer is too short
Some customers find that the shielding effect is not ideal when using the mobile phone signal jammer for mobile phone shielding. The effective shielding range is only a few meters. After eliminating the possibility that the mobile phone signal jammer itself is working normally and without failure, it is generally because the base station is close Or there is a large storage of signal amplifiers around, then, whether this is the case can be verified by the following methods:
1. Choose a cell phone signal jammer for testing and bring it to your home or other different units for on-site testing. You will see that under different on-site environments, one is that the shielding distance of the mobile phone will be different, and the other is that it cannot be The type of shielding, after changing different sites, the shielding effect of mobile phones will appear or be strengthened.
2. At the site where the base station is close and the shielding distance is affected, place the mobile phone within 1 meter of the mobile phone signal jammer, keep the mobile phone in standby for 1 minute, do not perform any operation for 1 minute, and observe whether the mobile phone is still there after 1 minute Signal or make calls, surf the Internet, etc. If there is no signal, it can basically be determined that the mobile phone signal jammer is working properly.
3. Search for "Cellular-Z", an APP dedicated to querying base station information. And judge whether it is because the base station is too close that the mobile phone signal jammer is not effective for mobile phone shielding.
