Communications Center. The emergency radio communications systems used by public safety first responders in outhwest s Fire and other emergency services use all areas of all structures is not feasible. An engineered radio communication system designer will analyze the coverage area desired and select repeater locations, elevations, antennas, operating frequencies and power levels to permit a predictable level of reliable communication over the designed coverage area. One radio communicates up to the repeater, this is called uplink, and then the repeater repeats that transmission down to the radio on the other side of the hill, this is called downlink. Firefighting is one of fifteen main Emergency Support Functions (ESF) established by the government to organize the response structure for any type of emerge. Implemented several years ago, the system enhances mobile and portable communications by using a sophisticated repeater system that enables radios to be heard at greater distance than the previously utilized 33 mhz conventional radios. From Personal Protective Equipment to fire pumps to radio communication systems, firefighting technology advances all work together to improve firefighter safety and effectiveness.
