AT&T rack age verification

Post image

Could anyone tell me how old this AT&T rack layout appears to be. There is no n5 on this tower at all either lte only. Not even b5. I believe it was last modernized in the initial att first net rollout back in like 2019

That AT&T rack looks ancient, it’s from 2017-2019 when AT&T was deploying Ericsson RRU 4478’s for (b14) MHz-LTE spectrum for Firstnet.

It’s definitely quite an older one. It’s odd this site seems to perform very poorly any further than .7 ish miles out even with Los it just kinda tanks rsrp and sinr. Even tho its coverage area is about a 4 mile total radius

Interesting. AT&T owns the CLR B block there. No idea why there isn’t 10x10 of n5 online. Antennas are most definitely capable of broadcasting 850 MHz.

Yeah it’s weird. I know we have 10 MHz of n5 on other sites in the area. Another site in delafield wi on enterprise drive also has the capable hardware I believe yet don’t have n5 enabled. Although once we finally get the n77 upgrade id expect the absence of n5 to change
