(WCSC) - The state of South Carolina is making it easier for the public to see where highspeed broadband internet is â and isnât â available. Officials say the South Carolina Broadband Map shows the availability of broadband service to every home and business in the state. The idea is to have a map of South Carolina where you can see all of the structures that are capable of having broadband brought to them. Officials with the Office of Regulatory Staff took that and then combined it with the data provided by the broadband providers that show where they actually are.
