Broadband internet is another name for high-speed internet service, usually defined as 25Mbps or faster. There are four major types of broadband internet: cable, DSL, fiber, and satellite. The average broadband speed in the US is 124Mbps, but DSL is much slower at about 35Mbps, and fiber is the fastest at 1,000Mbps.

In telecommunications, broadband is the wide- bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast internet connections. The medium can be coaxial cable, optical fiber, wireless Internet (radio), twisted pair, or satellite.
