IX  Broadband vs. Baseband Networks

Another method used to classify networks, is describing the underlying signaling technology used in moving data from one network host to another.

In baseband, there is a single signal traveling on the cable at a time. In broadband, there are multiple signals on the cable simultaneously, using a wide band of frequencies.

You can think about broadband vs. baseband as being a comparison between a 6-lane highway and 2-lane highway for data. Both may have the same speed limits for individual cars, but the 6-lane highway has the capacity to carry more cars at a time, than does the 2-lane highway. Keep in mind that more lanes typically mean more speed, and it is not a promise.
