Definition: Technically broadband is used to define any transmission which can carry more than one channel on a single medium. For instance, the coaxial cable for your cable TV carries many channels and can simultaneously provide Internet access. Broadband is also often used to describe high-speed Internet connections such as cable modems and DSL, or mobile boradband in the case of cellular data connections.
In January of 2015 the FCC changed the definition of broadband to be a minimum download speeds needed from 4Mbps to 25Mbps, and the minimum upload speed from 1Mbps to 3Mbps.
