This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as the phenomenon of searching the network, mobile phone no signal, no service system, etc.The cell phone jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation.

The interference signal emitted by the jammer will be attenuated to different degrees after passing through the obstruction, please try to prevent it.Indoor-type shielding device is recommended to be placed at a height of about 180cm-220cm from the ground, and the angle is preferably forward.
Choose different places to use different models and models from the purpose. If they are used in the prison detention center military area, they require 365 days of continuous use. In this way, choose a shield with better heat dissipation and stable performance. The choice of different venues is also different.The weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the shield.The farther the shielding environment is from the base station, the stronger the theoretical shielding effect of the shielding device.
