If your carrier is still using T1 I’d be shocked. You could do essentially zero data and you’d likely still be using GSM. Maybe a low bandwidth CDMA.
We went to fiber to cell site in 2013, with the other carrier right behind us. The bandwidth required has grown exponentially since that time. The fiber services (mostly ATT in the south) can’t keep up with the demand. They held up hundreds, maybe thousands of bandwidth upgrade saying they couldn’t get the SFPs
. Maybe, but COVID was used to blame a lot of fuckery.
The customer would probably be shocked if they knew just how much all the carriers depend on one another. Anyone remember the Christmas bombing in Nashville ? Tells you everything you need to know about backhaul planning.
