Important Notes:

The jamming distances we mentioned on website are for customer's reference only. The actual jamming distance will be varied depending on the signal strength and the use location

The jamming area is influenced by the location of the cell tower and the obstacles between cell tower & the cellular jammer. It means that in normal condition if the distance is close between the cell tower & the cellular Jammer, it will have very less jamming area. Likewise, if there are obstacles & walls between the cell tower & the cellular phone, the jammer will give more jamming area.
