This is due to the connection between the environment in which you are using the cell phone signal jammer. Under what circumstances is the cell phone jammer's effect small?

Professionally, there are many reasons, but there are three reasons that come closer to our average customer:

1. There is a base station around the cell phone signal jammer, possibly closer to the base station

2. The cell phone signal jammer being used is located next to the cell phone signal booster or signal booster.

3. The surrounding wall of the cell phone jammer being used is relatively thick, especially the reinforced concrete wall. A low-power machine can be especially bad when it runs through walls.

And the current cell phone signal jammers are all used without affecting the uplink (base station) capabilities, so while they do not affect the use of cell phones by peripheral personnel, it also improves the environmental requirements of the cell phone jammer. With the Shankino signal jammer for cell phones, the signal strength of the surrounding cell phones is checked before purchasing the signal jammer and then the appropriate signal jammer is selected according to the actual signal strength.
