Tunnels / public security and fire radios GPS solutions Solutions Wireless relay network program

Tunnels / public security and fire radios solutions GPS solutions tunnel radio relay network programs dedicated wireless communication system includes: a dedicated dispatching communication subsystem (wireless intercom) 350MHz Police Fire analog communications subsystem and the introduction of 350 / 800MHz digital communications system into the public security subsystem. Private wireless communications system equipment mainly by dispatching host POLICE 350 / 800MHz digital trunking, the band optical fiber and optical fiber repeater Repeater Donor Unit Remote Unit, antennas, radio, signal distribution equipment, road equipment division (POI) and leaky coaxial cable (LCX) and other equipment. Under normal circumstances, the monitoring center with scheduling host SECURITY 350 / 800MHz digital trunking, public security and fire control 350 / 800MHz band frequency selective repeater and each fiber Repeater Donor Unit, signal through fiber optic repeater Donor Unit, transfer to the tunnel working well fiber optic repeater Remote Unit. The main tunnel and service tunnel set up the band repeater Remote Unit, the main signal output to the leaked cable, covering underground tunnel driving range segment. An indoor antenna coverage each sucker layers equipment room and equipment room inside the main channel. 1. Wireless Communication Wireless Communication System for providing internal tunnels handheld terminal means of communication between the working surface, cover tunnel management area. The system should be able to repair the tunnel, rescue, establish flexible communication liaison between patrol officers and control room managers and design, it can send information, notices and orders for the tunnel staff scheduling base station control center, etc. for emergencies timely command and staff scheduling. And may establish a link with the outside calls by dialing system. 2. Fire and police radio into the tunnel wireless receiver system can also provide police and fire intercom transfer function and its corresponding relay station communications center that police and firefighters in the tunnel with the outside world handheld station communication open. Realized and covering fire and police radio communication system. 3. Private wireless communications system network tunnel system, said system communication platform consolidation, unified meet the tunnel security, fire, scheduling, operations, safety requirements demand. RF signals of all the private wireless communications subsystem into a leaky cable in order to save space resources of the tunnel. 4. System monitoring signal relay device of all private radio communication subsystem (including optical fiber repeater proximal / distal, frequency repeater, etc.), with monitoring, monitoring personnel can set up a computer terminal in the tunnel control center completed monitoring and control.
