Baseband refers to a signal in its original, unmodulated state, occupying a frequency range starting from near zero hertz. In networking, it describes systems where the entire bandwidth of a medium carries a single digital signal, rather than splitting it into multiple frequency channels. Ethernet is the most common example of a baseband network.
