Improvement and Utilization of Auxiliary Radio Communication System

An auxiliary radio communication system is a fire extinguishing necessary for smooth between brigade and the ground command departments performing rescue activities at disaster sites such as basements, tunnels, high-rise buildings. The ability to provide field personnel site determines success of operation. However, reinforced concrete structures used in modern buildings reflect, refract, diffract waves. Thus, they represent largest obstacles transmission reception. To compensate this aspect, leaky coaxial cables antennas can be installed enable stable departments. Nevertheless, most sites, systems are rarely used. This because existing connection terminal box method inconvenient firefighters, range reception limited substandard. In general, safety standards were revised after converting firefighting radios digital owing revision Radio Act, but problems areas design, supervision, inspection did not improve. study, performed with by analyzing addressing systems.
