There are several different types of repeaters; a telephone repeater is an amplifier in a telephone line, an optical repeater is an optoelectronic circuit that amplifies the light beam in an optical fiber cable; and a radio repeater is a radio receiver and transmitter that retransmits a radio signal. In computer networking, because repeaters work with the actual physical signal, and do not attempt to interpret the data being transmitted, they operate on the physical layer, the first layer of the OSI model; a multiport Ethernet repeater is usually called a hub. One way to overcome this is placing a repeater (or base station) at the top of the hill. Some types of repeaters broadcast an identical signal, but alter its method of transmission, for example, on another frequency or baud rate. Organ des Elektrotechnischen Vereines in Wien.- Heft 3, 16.

Repeaters can also be located in fire apparatus and command vehicles for use on particular incidents where communications are problematic. The lack of coordination, and communication are some of the problems that can interfere with the response to a disaster. Sometimes separate transmitting and receiving locations are used, connected by a wire line or a radio link.
