Which gives the best network in Vasavi Engineering college?

Some of my friends are from Vasavi Engineering College. According to them, there are different parameters to decide which among all the mobile networks work best. Here is a brief overview of what I have learned from them:

• In the CV Raman Block, which is for the Mechanical department, mobile networks like Airtel, Idea, and Vodafone work better than most others. 
• Networks like Airtel, Jio, and Idea seamlessly provide the best speed around these two places. 
• When coming down to the Mechanical and Civil labs, networks like Jio, Idea, and Airtel work the best.
• Airtel, however, is considered to provide the best network speed in the Ramanujan block, where the CSE and IT blocks are situated.
• For both the first-year students and the Civil block in the Vishveshwarya area, Airtel works best by all means. Idea and Jio can be considered second in this list.
• In the JC Bose block, established rather for the EEE and ECE block, Airtel and Idea do work reasonably well.

These are some of the facts I got to know from my friends studying there.
