10 Channels Long Distance Communication System

  As the increasing require for prion communication interference, the signal shielding solution for prison has developed.In most of the existing prison and detention center, mobile phone signal blocking systemsare traditional wall-mounted analog jammers, which transmit sweeping signals through VCO sweeping in the full frequency band. It transmits interference signals in the uplink and downlink frequency bands and uplink and downlink time slots of the base station, which has stronginterference to the uplink ofbase station,resulting in inability ofnormal communication insurroundingarea. Therefore, the technology of prison machines is constantly being improved.

  We ZD TECH will announce an adjustable frequency 10 channels prison signal jamming system. The main features of this system are as below: Intelligent shielding of all-standard signals, real-time monitoring of system operation, regional and time management.The digital signaling-level intelligent shielding system is mainly composed of outdoor signal acquisition antennas, shielding main equipment includingnear-endandremote, passive indoor distribution system and communication detection and control platform. According to the plane structure, area size, wall barrier of prisons and detention centers, and combined with the network signal of operators tested on site,telecom operator-level passive indoor distribution systems are deployed in prison cells, canteens, workshops, confinement rooms and teaching rooms that need to be shielded. The shielding points on each floor are determined according to the design requirements and specific installation locations.

  At ZD TECH, we are committed to advancing secure and intelligent prison communication management through cutting-edge technology. Our adjustable-frequency prison signal jamming system redefines precision shielding by combining operator-grade passive distribution, real-time monitoring, and adaptive signal suppression—ensuring compliance while minimizing collateral interference. By addressing the limitations of traditional analog jammers, we deliver a future-proof solution tailored to the unique structural and operational needs of detention facilities.
