I've come across a number of Crown Castle oDAS nodes (small cells) on T-Mobile. I think a bunch used to belong to MetroPCS. I found 3 in my own neighborhood and one in Williamsburg. The ones on my neighborhood all share the same the same eNB ID which makes it annoying to track on Cellmapper since it's 3 separate "sites" but only one marker.
I'm not seeing any frequency info on my T-mobile phone, but the stale data issue appears fixed. When I force it to B12 the 5G info disappears immediately. I can't test on my AT&T phone ATM, it appears they are working on my home site again and all I'm getting from it right now is B12. Sent a diagnostic report from my T-mobile phone and will send one from my AT&T phone once I get an NR connection on it. Sent from my SM-G986U using Tapatalk
