broadband
Synonym discussion
Sense: noun/1
'Broadband' usually means a fast internet service coming into a home, school, or office. 'Internet connection' is broader and can mean any way of getting online, including mobile data or an older slow system. 'Wi-Fi' is different: it is the wireless signal inside a building, not the outside service itself, so you can have broadband without using Wi-Fi if you connect by cable. 'Fiber' is a narrower word for one kind of broadband that uses fiber-optic lines and is often faster and more stable. A house may have broadband from a provider, a router may share it through Wi-Fi, and a premium plan may be fiber rather than ordinary cable broadband.

Etymology
Formed in English from 'broad' and 'band'. It first described telecommunications systems that used a wide range of frequencies. In everyday modern English, the word is now mainly used for fast, always-available internet service and for things connected with that service.
