We have that available, I just use mobile data because I disagree with their ToS.
The ToS is so restrictive that you basically immediately break it after connecting a device. I was told that, of course, they don't really care.
Except - there is a point stating the provider has the right to access your computer if there is a suspicion of ToS violation. Considering the network here is a student-run organization, that could easily be exploited if you piss off someone.
Maybe I am just paranoid, but no thanks.

Otherwise, from talking with them, most dorms have 1Gbit, some have 2.5Gbit, and all share a 40Gbit link which could apparently do 100Gbit (I think), but it's capped due to licensing.
They leverage national academic network.
Oh, and they also got a class B subnet back when everyone was sure there's just way too many IPv4s, so NAT isn't being used here.

Ah good old dorms. My first t3 line. So much media downloaded, uh, with the express written consent of the license holders I swear
