5G Selective Cellular Communication Controller is highly integrated with 2G/3G/4G/5G-NSA signaling protocol stack and adopts active working mode. Unlike a broad-spectrum jammer that blocks all frequencies within a given range, a vehicular selective jammer is designed to target only specific frequencies used by cellular networks. This allows the jammer operator to disrupt communication on certain networks while minimizing interference with others.

This device can cut off the communication function of illegal cellphones within a specific area, prevent information leakage while keeping the cellphone communication of VIP and security personnel smooth.
