The purpose of signaling and encoding schemes is twofold. First, the schemes provide methods to allocate the available transmission medium's bandwidth. Second, they provide a signal formatting language of sorts so that signals transmitted across the medium will have some actual meaning and can be interpreted logically. Two types of signaling exist: baseband and broadband. LAN transmission protocols commonly utilize baseband signaling schemes, whereas WAN transport protocols tend toward broadband signaling.

With broadband signaling, the bandwidth of the transmission medium is partitioned into different frequency ranges. Each frequency range represents a different channel, each of ...
