What Is Broadband Communication?

Broadband communication is a way of transmitting multiple channels of data over a single medium. The medium may be DSL line, coaxial cable, twisted pair cable or wireless broadband.

Broadband technology allows companies to offer high-speed Internet to users. The minimum speed for broadband is 25 megabytes per second, as of May 2015.

The two main types of broadband used by consumers are DSL and cable modem. DSL is transmitted over copper telephone lines. It provides a dedicated Internet connection that users don't have to share. A cable modem connection provides Internet through the cable television line. Users do have to share their cable broadband with other subscribers, so speeds may vary depending on how many users are logged on.
