Broadband (short for “broad bandwidth”) refers to high-speed internet connections that are "always on.” Broadband provides the fastest service today, with popular residential service types includes DSL, fiber, wireless, and 4G/5G LTE.
Broadband was introduced in the late 1990’s and mostly replaced older dial-up connections, which used the audible frequency of telephone lines. Because broadband runs on a different frequency, it’s easier to stay online with a faster connection. This allows people to quickly upload, stream and download large files. Let’s take a closer look at how broadband technologies work.
