Baseband Networking Definition/Meaning:
Communication in which a digital signal is placed directly on the transmission medium without requiring a carrier, i.e. without modulation. Only one signal may be present on the baseband channel at a time. This type of signaling, baseband signaling, is also called dc. signaling because in some baseband networks a continuous d.c. voltage is present when the data does not change. Baseband networks may use twisted pair or coaxial cables for data transmission. The Ethernet is a prototype local area network using baseband signaling on a coaxial cable.
