How to test the shielding distance of wireless signal jammer
2022-10-27
Afraid of incomplete shielding? The natural environment of data signals is complex, so we are afraid of insufficient cost budget? Afraid of being damaged, short equipment cycle? Is it only to shield one data signal, for fear that other frequencies may be short? Afraid of being detected by others after installing a signal shield? Afraid that the signal shield will be ugly and endanger the indoor air?
Detect that the shielding spacing frequency of the wireless signal jammer is below:
1. Detect whether a certain positioning point is in the shielding range. It is reasonable to hold the mobile phone for more than 30 seconds to determine whether the mobile phone is jammed by wireless signal.
2. If you move from an unshielded area to an unshielded area, you will usually walk into the unshielded area for a very long distance before the phone is completely blocked. This is because once the phone is unplugged, the phone has its own anti-interference capability. This kind of anti-interference will enable the phone to automatically adjust the signal strength to ensure all normal voice calls this time. Therefore, it is generally not recommended to carry out dynamic inspection in voice calls, but to carry out static data detection at each location.

Therefore, it is generally not recommended to carry out dynamic inspection in voice calls, but to carry out static data detection at each location.
4. Prepare several frequency bands of mobile phones in advance, including: Mobile GSM, China Unicom WCDMA, PHS, and 3G (3G with three styles: Mobile TD-SCDMA, China Unicom CDMA2000, and WCDMA of the telecommunications network). Then turn on the mobile phone signal blocker, hold each mobile phone, and detect the reasonable shielding of the signal blocker from the near to the far from the installation position of the landless signal jammer, and shield the gap in several directions.
5. When checking whether the mobile phone is blocked, you should not just check the number of data signal cells on the mobile phone. Because the number of data signal cells on the mobile phone is sometimes falsely reported, it does not mean the real communication situation on the mobile phone today. At this time, you should not draw a conclusion too early that this signal blocker has no practical effect. While it should be possible to try to dial the local toll free phone or fixed landline number on the mobile phone intermittently. If the call is blocked, it is judged that it is still within the scope of shielding. On the contrary, if the call is accessible, it indicates that it has exceeded the scope of shielding.
