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

Originally used to mean 'using a wide-spread frequency' and for services that were analog at the lowest level, nowadays in the context of [[Internet access]], 'broadband' is often used to mean any high-speed Internet access that is seemingly always 'on' and is faster than [[Dial-up Internet access|dial-up access]] over traditional [[plain old telephone service|analog]] or [[ISDN]] [[public switched telephone network|PSTN]] services.<ref name="FCC2014">{{cite web |url=https://www.fcc.gov/general/types-broadband-connections |title=Types of Broadband Connections; Federal Communications Commission |publisher=[[Federal Communications Commission|Fcc.gov]] |date=2014-06-23 |access-date=2022-06-05 |url-status=live |archive-url=https://web.archive.org/web/20220605084322/https://www.fcc.gov/general/types-broadband-connections |archive-date=2022-06-05 }}</ref>

The ideal [[telecommunication network]] has the following characteristics: ''broadband'', ''multi-media'', ''multi-point'', ''multi-rate'' and economical implementation for a diversity of services (multi-services).<ref name="Lu">{{cite web|title=ATM Congestion Control|author=Lu, Fang|url=http://www.cse.ohio-state.edu/~jain/cis788-95/ftp/atm_cong/index.html|accessdate=1 March 2005|url-status=dead|archiveurl=https://web.archive.org/web/20050210124709/http://www.cse.ohio-state.edu/~jain/cis788-95/ftp/atm_cong/index.html|archivedate=10 February 2005}}</ref><ref name="Saito">{{cite book |author=Saito, H. |title=Teletraffic Technologies in ATM Networks |publisher=Artech House |year=1993 |isbn=0-89006-622-1 |url-access=registration |url=https://archive.org/details/teletraffictechn00sait }}</ref> The [[Broadband Integrated Services Digital Network]] (B-ISDN) was planned to provide these characteristics.
