Some definitions of broadband require the connection to be “all the time on”. This might imply that cable would all the time match into this class, however some ADSL and satellite tv for pc connections wouldn’t. With fiber optic know-how on the rise it’s attainable that the speeds which might be thought-about broadband may change within the close to future.

The upper communication class of a broadband connection makes use of extra frequencies than a POTS line, permitting for the sooner transmission of knowledge.
