Smart TV without satellite connection?

Have a question: Can you actually use a Smart TV without a satellite connection if you only want to watch Netflix or other streaming services? I don't have a satellite connection in my room, but I would still like to buy a Smart TV for Netflix. Is that possible?

Of course it works if you have an internet connection in your room, either LAN or WLAN

Goes of course, in this case you need an internet connection or Wi-Fi

Sure is.

Streaming apps has nothing to do with TV reception, but only with the Internet that your TV uses via Wi-Fi.
