I have a theory that I want to share about sites that aren't part of the #Cornerstone agreement for some reason and are #O2 only.

I reckon the LACs indicate when a site is O2 host and isn't shared with another network. I think whenever a 2G LAC begins with 22xxx, it's O2 only (regular sites begin with a 21xxx LAC).

* Case 1: Eastern Avenue in Mitcheldean. Broadcasts under BTS 9147 on LAC 22212, using an O2 host site ID of 038910.
* Case 2: random airport in Wales. Broadcasts on 2G, 3G and 4G, no indication of the 4G eNB popping up on Vodafone. Broadcasts on 2G under BTS 4147 with LAC 22860, site ID is 051035. 4G eNB is 545714 afaik (I couldn't be bothered to convert the cell ID to hexadecimal to check).

I think something similar happens on some O2 only 3G only sites, but I can't really confirm whether it's on any macro sites. I can confirm it happens on some boostboxes though, with 18xxx and 19xxx LACs.
