A small-business owner purchases a building and wants to establish an internet connection.

Cable internet is the most appropriate recommendation because it commonly uses coaxial cabling between the service provider’s network and the customer’s cable modem. A coaxial wall jack normally terminates with an F-type connector and indicates that the building may already have cable television or DOCSIS-compatible broadband infrastructure. A technician can connect a cable modem to this outlet and then connect the modem or gateway to the business network. Fiber service requires optical fiber and an optical network terminal rather than a standard coaxial outlet. DSL operates over copper telephone wiring and typically uses an RJ11 connection. Satellite internet requires an externally mounted satellite dish and does not depend on an existing coaxial broadband wall jack, although coaxial cable may connect the dish to indoor equipment. The installed jack therefore most strongly indicates cable internet availability.
