Network - Baseband

In networking, a baseband connection is one that uses digital signals, which are sent over wires without modulation; that is, binary values are sent directly as pulses of different voltage levels rather than being superimposed on a carrier signal (as happens with modulated transmissions). Baseband networks can be created using twisted-pair, coaxial, or fiber-optic cable. Even though only a single digital stream is transmitted over a baseband connection, it is possible to transmit multiple signals. This is done by multiplexing (combining several signals in a transmission by interleaving the signals using, for example, time slices). This digital signaling is in contrast to broadband, in which analog signals are sent over multiple channels at the same time. Each channel is allocated a different frequency range.
