Hello everyone... I noticed that AT&T recently aquired a 700mhz license for 710-716 and I think 738-742 in my area. They've done a ton of LTE work in surrounding counties, but I'm still on 4G HSPA +. I also noticed that these (see picture) are on a building in the area. Are these LTE antennas waiting to be activated? I used field test mode to find I was essentially on top of a tower. (-62) cell strength. Thanks for your help!
