What method can be used to verify the situation that the base station causes the mobile phone signal jammer to shield the mobile phone from a short distance?
When some customers use mobile phone signal jammers for mobile phone shielding, they find that the shielding effect is not ideal, and the effective shielding range is only a few meters. Or if there are signal amplifiers around, then, whether this is the case can be verified by the following methods:
1. Choose a mobile phone signal jammer for testing, and take it to your home or other different units for on-site testing. You will see that in different on-site environments, first, the shielding distance of the mobile phone will be different, and second, it was originally thought that it cannot be used. The type of shielding and the shielding effect of the mobile phone will appear or be strengthened after changing different sites.
2. In the scene where the distance between the base station is close and the shielding distance is affected, place the mobile phone within 1 meter around the cell phone signal jammer, keep the mobile phone in standby state for 1 minute, do not perform any operation for 1 minute, and observe whether the mobile phone still exists after 1 minute. Signal or make phone calls, surf the Internet, etc. If there is no signal, it is basically certain that the cell phone signal jammer is working normally.
