The Southern Company here in Alabama runs Smartmeters.
Licensed 900....very small band between 900Mhz and 902Mhz.
Probably a slice from their Southern Linc Cell allocation.
They actually do pretty well with it.

I talked some with a technician that came out to install the
smartmeter on our house a month or two ago.
We are in limbo. I didn't tell them they couldn't install it, but
I told them it would have to lock out specific frequencies if they
didn't want me to wrap it in a Faraday cage. He elected to defer
the installation. We have been going around like this for 3 or 4
years, and they still haven't installed our smartmeter.
No big deal. All of our neighbors still get their meters read by
the old, manual method. Seems the meters are too far apart to
actually work anyway. In the mean time, they just pollute the 900
MHz band.
He told me that PG&E was switching over to ~~ 450 MHz (I don't
know the exact frequencies) because they needed better range than
they could get at 900 MHz. In fact, he said they were licensing
whatever frequencies they are switching over to. I'll believe it
when I see it.

Ouch. That's what I was worried about. Now ComEd is going to
roll out smart meters across their entire service area in
about a year and I fear we're going to have to abandon 900
altogether because of it. Guess we'll be trying some TVWS,
until they shit on that too.

Had to go to 5 MHz channel to stay registered, 1X MIMO-A,
about 2 Mbps aggregate throughput on linktests. That's
useless.
I can't say I'm all that surprised, the signals are bad
and the interference is worse. But the only way to find
out was to try it.

So what did you get, about 10dB SNR and 5Mbps of throughput?

We swapped out an FSK AP in a high interference area
today. No magic, works about the same.
Too bad, even the installer liked the SM and antenna.
Even the coax boots are nice.
Will probably work well for those of you who don't
have -65 noise floors.
We are going to have to give up on 900 MHz at this
location. This was the last gasp.
