Chapter 4: Fire Service Communications Flashcards | Quizlet Walter Leal Hamburg, Telephone repeaters were the first type of repeater and were some of the first applications of amplification. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. A router operates on the Network layer (layer 3) of the OSI model and uses routing tables to understand where traffic is coming from and where it should go. This is used to extend the range of coverage of a radio signal. The first relay system with radio repeaters, which really functioned, was that invented in 1899 by Emile Guarini-Foresio.[2]. Firefighting is one of fifteen main Emergency Support Functions (ESF) established by the government to organize the response structure for any type of emerge. 0000062342 00000 n how does a repeater system enhance fire service communications quizlet 4 Fire Service Communications Quiz.
