How get the most out of a signal jammer

For better shielding effect, cell phone jammer can also be placed on a chair or table with a distance of 1.5-2 meters from the ground. Of course, it can also be placed on the ground directly, depending on the local wireless signal strength, or it can be placed in front of the classroom, to better protect the shielding effect.

If you only want to place a shield and are worried that it will be difficult to screen the area behind the classroom from the podium in front, you can place the shield in the middle of the side of the classroom. At this point, the shielding device needs less length on both sides of the shield, and the effect will be better. Of course, the power cord needs to be fixed. There may be no power jack in the middle.
