Speaking from Airtel point of view..
There used to be a tower 700 metres North of my place, and another over 1 km South. Apparently, there is a tower about 400 m East of my place as well, making that tower the nearest. The locations of these towers is according to Tarang Sanchar portal.
Problem is, my
Android shows it is always connecting to the tower that is 700 metres N of my place. ALWAYS. Same for the
iPhone.
I am beyond baffled as to why wouldn't it pick the tower that is 400 m E of my place.. that should be the closest tower, and according to Tarang Sanchar, it is 2G and 4G enabled.

I am thinking we have a situation of overloaded towers and bandwidth being spread too thin. I can't help wonder what would happen if somehow my phone were to connect to the closer tower.
About foot and vehicular traffic, no. High rise.. there is one, that is standing between our society and the tower that is 400 metres East of my place, but that building was nearly complete when I was getting those great speeds a few months ago.
When Airtel and Jio received spectrum, I did see CA in both Jio and Airtel on my devices, and speeds improved. Jio was consistently around d35 Mbps, Airtel was more, 45-50 average and touching 80 at night. But, that bliss lasted only a month or two. Neither do I get good speed in the area, nor do I get CA now, on both Airtel and Jio. Something has definitely changed.
And that's Airtel response on the upgrade to 1 Gbps...more than 24 hours after I spoke to the call center rep. These guys are such dorks. Moving slowly even if it means losing money. Response times to 1 Gig is 
...a repeat of '21. They must be looking for a
