In telecommunications, broadband is a wide bandwidth data transmission with an ability to simultaneously transport multiple signals and traffic types. The medium can be coaxial cable, optical fiber, twisted pair, or wireless broadband (wireless broadband includes Mobile broadband).
In contrast, baseband describes a communication system in which information is transported across a single channel. In the United States, the Federal Communications Commission (FCC) reflecting advances in technology, market offerings by broadband providers and consumer demand, updated its “broadband benchmark speeds” to 25 megabits per second (Mbps) for downloads and 3 Mbps for uploads. The 4 Mbps/1 Mbps standard set in 2010 was found by the FCC to be dated and inadequate for evaluating whether advanced broadband is being deployed to all Americans in a timely way.
Different criteria for “broad” have been applied in different contexts and at different times. Its origin is in physics, acoustics, and radio systems engineering, where it had been used with a meaning similar to “wideband”. Later, with the advent of digital telecommunications, the term was mainly used for transmission over multiple channels.
Whereas a passband signal is also modulated so that it occupies higher frequencies (compared to a baseband signal which is bound to the lowest end of the spectrum, see line coding), it is still occupying a single channel. The key difference is that what is typically considered a broadband signal in this sense is a signal that occupies multiple (non-masking, orthogonal) passbands, thus allowing for much higher throughput over a single medium but with additional complexity in the transmitter/receiver circuitry. Finally, the term became popularized through the 1990s as a marketing term for Internet access that was faster than dialup access, the original Internet access technology, which was limited to 56 kbit/s. This meaning is only distantly related to its original technical meaning.
In telecommunications, a broadband signaling method is one that handles a wide band of frequencies. “Broadband” is a relative term, understood according to its context. The wider (or broader) the bandwidth of a channel, the greater the information-carrying capacity, given the same channel quality.
