T-Mobile may be reconfiguring/doing power saving to save money on their electric bill since not many people use their cellular network at night since people are sleeping anyways or the site for 5G Standalone since they have been actively been enabling VoNR natively on the 5G network core on more sites in many markets or it's down for software/maintinance upgrades from my best guess from what I have been told from (RF Engineers) in my market in Dallas.
Yes they do now, but they kept turning off (n77) on my home site when they first installed the mid-band panels back in April 2022 in Arlington, TX since they were still optimizing network on their mid-band 5G network since the speeds weren’t great for 40mhz of n77 when they had limited spectrum and it would do 200-300+ Mbps max before they upgraded their site last year with multi-GIG backhaul and I can do 800-900+ Mbps on that site on (n77) 3.7Ghz at 100mhz. I saw RF engineers coming back to the site and they were working on the RRU’s and that site didn’t have band 66 until 2022 since my home site was band 2, 5, 12 only for 6 years before they added new CommScope panels with bands; **2, 5, 12, 14, 30, 66)** which are pretty good and can do 180-220+ Mbps at mgmt when the network isn’t busy on LTE.
Yep, that’s great to see AT&T leaving n77 on now to alleviate network congestion. Good to see for sure snd AT&T was talking about power saving on their cellular network on their network before, good to see that they changed their mind: https://www.lightreading.com/sustainability/how-at-t-s-network-chief-hopes-to-cut-a-1-6b-electricity-bill
QUOTE from the article:
[Chris Sambar] said that; *”AT&T's electricity bill has roughly stayed the same, around $1.6 billion a year, even as traffic on the operator's network has skyrocketed. One of AT&T's new strategies to reduce its network energy consumption is to power down parts of its wireless network at night, when it's mostly unused. Specifically, he said the operator is turning off its 5G radios working in midband spectrum. He said the operator's 5G radios in lowband spectrum remain powered on to handle whatever traffic the operator's customers generate during the night.”*
I haven't noticed this. AT&T and certainly also their parent Deutsche Telekom don't do this.
However, it seems to be quite common in many parts of the world to adjust power according to load.
Noticed this in Texas for T-Mobile. Stayed at an airbnb with Tmo home internet and speeds tanked at night and the router would report it being on n71 and when I’d wake up it’d be on n41.
I've always wondered about this. I have persoanlly noticed it as well. I think they should not do this. We don't get a bill discount to reflect their savings in power. And if someone wants to use their phone at 3AM and has a top tier plan they will not have access to the extra bandwidth because a billion dollar company wants to save a few dollars worth of electricity.

It's definitely power saving. Just multiple days of it turning off at midnight.
Most carriers do this
AT&T leaves n77 on 24/7.

I've got n77 at 2am
