Today, many of our important data and communication content is transmitted over a wireless network. For everyone in the receiving range of access to the network, hidden many unsafe factors. If the use of improper or unprotected awareness, caused by wireless password leakage will lead to rub the net. Light will be preempted by the bandwidth caused by network card, the heavy will suffer from network attacks, data theft caused by loss.

receiving so many signals, this blocker can intelligently identify and find the mobile phone to be tapped. The mystery is that the pseudo base station can obtain the IMSI number of each mobile phone in the air. The IMSI number is unique, just like the mobile phone's "ID card number. After a pseudo base station obtains this number, all signals sent from this mobile phone are blocked.
