Transporters must be like air travel is today.
Think about it. One can transport literally in a second from NYC to London. In the real world, a flight would take hours. And obviously it is applicable anywhere in the world, and underground to an extent (say to a depth of 1 kilometre, which is quite deep).
There must also be restrictions in use though. Most likely there are public transporter pads, operated by the Federation and/or planetary government. And private residences may have shields to prevent unauthorised transporter beams.
