In telecommunications, broadband or high speed 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 access. The transmission medium can be coaxial cable, optical fiber, wireless Internet , twisted pair cable, or satellite.
A method of connection to the internet using existing copper phone lines using a modem on the client's end to send information at a slow speed, normally reaching maximum speed at about 56 kbit/s. This technology uses the voice spectrum of the telephone lines to transmit data using a system of sounds that only the receiving modem or ISP understand.
In March 1990, the first high-speed T1 (1.5 Mbit/s) link between the NSFNET and Europe was installed between Cornell University and CERN, allowing much more robust communications than were capable with satellites. [48] Later in 1990, Tim Berners-Lee began writing WorldWideWeb, the first web browser, after two years of lobbying CERN management.
The term “broadband” refers to a high-speed internet connection that uses a satellite, digital subscriber line or cable connection for data transmission. A broadband connection is usually a lot faster than a dial-up connection and allows you to browse the web and download videos, music and games much more quickly.
In March 2024, the FCC announced a new benchmark for "high speed" or broadband internet as download speeds of 100 Mbps and upload speeds of 20 Mbps. Most internet providers offer plans starting at ...
Originally the word "broadband" had a technical meaning, but became a marketing term for any kind of relatively high-speed computer network or Internet access technology. According to the 802.16-2004 standard, broadband means "having instantaneous bandwidths greater than 1 MHz and supporting data rates greater than about 1.5 Mbit /s."
Mobile broadband is the marketing term for wireless Internet access delivered through cellular towers to computers and other digital devices using portable modems.Although broadband has a technical meaning, wireless-carrier marketing uses the phrase "mobile broadband" as a synonym for mobile Internet access.
