Which mobile network is better in IIT Ropar?

My brother who used to be a student at IIT Ropar informed me that Airtel and JIO provide the best network connectivity in the campus premises of IIT Ropar. 

Wi-Fi offers an internet speed of 80 to 90 Mbps which is a lot better than what you would receive via the regular mobile network or internet connection services providers. The campus of IIT Ropar is facilitated with Wi-fi connectivity that is available 24 X 7 throughout the premises.
