We have a 100 mb Ethernet connection that is shared in the SD campus. Other campuses have some smaller internet connections and they have similar restrictions
We limit guest access for the entire ssid to 15 mb. We unrestrict this for big events like career fair, graduations, etc. This is the network for Student BYOD and guest visiting the campus.
School owned Ipads for student material and testing is unrestricted. These are only used in classes and by the executives.
We have the internal staff network at limited 20 Mb to keep instructors from shutting down the wireless during testing.
We had this happen a few times with instructors doing things they werent supposed to during student tests.
hope this helps.
