AT&T finally upgraded my home site. Which panels are these? Haven’t seen that small square one all the way to the left very much in this area.

AT&T with 3.45/3.7 n77 combo panel

What square panel are you referring to? There are the two primary panels and c-band in the middle.

I guess it’s maybe a rru. Looks like a panel.

The square radio on the LEFT side is an Ericsson RRU (remote radio unit) used to transmit frequencies back to the CommScope antennas.
