Mobile broadband subscriptions are mobile subscriptions that advertise data speeds of 256 kbit/s or greater. The subscription must allow access to the Internet via HTTP and must have been used to make a data connection via Internet Protocol (IP) in the previous three months. Standard SMS and MMS messaging do not count as an active Internet data connection even if they are delivered via IP. This indicator is measured in number of subscriptions per 100 inhabitants.

Fixed wired broadband subscriptions include the total number of subscriptions to the following broadband technologies with download speeds of 256 kbit/s or greater: DSL, cable modem, fibre-to-the-home and other fixed technologies (such as broadband over power lines and leased lines). This indicator is measured in number of subscriptions per 100 inhabitants and in total number of subscriptions.

This indicator provides information on how many businesses use a broadband connection. Data typically come from surveys/questionnaires given to a sample subset of businesses. The results are then extrapolated for the country as a whole. The drawbacks of the survey data are that it is collected infrequently and that the questions asked about broadband usage are not necessarily uniform across OECD countries. This indicator is measured in percentage of all businesses and is available by business size or by business sector.
