The smart meters here do a mesh/hub system. All the meters talk to each
other doing a FHSS mesh.
They figure out where the nearest hub is, and all the meters in a
neighborhood relay their information to the hub through the meter(s)
that are closest to the hub. So they are chatting all the time, and the
ones closest to the hub never stop.

I know I'm late to this thread. The only smart meter system in this
area is a polling system. The meter reader just drives down the
street while his truck transmits a polling message, which the meters
then reply to. The meters only speak when spoken too, so we never
really had a problem with those. There's still a huge labor savings
for the power company, and apparently it was a lot cheaper than
deploying the mesh system from the same manufacturer.
What I infer from these threads is the effect of this smart meter
stuff is heavily dependent on what equipment the power company bought,
how it's deployed, and how it's configured. So yeah, YMMV is the only
real answer.

Interesting. The majority of our 900 subs are located in prime smart
meter territory. I've worked with several of the power companies
across western Kansas and they all run a version of Landis Gyr meters
with is FHSS 900 ISM (see pic here

They transmit infrequently in short bursts...very little data. The
only time we see interference is when they mass update software. After
some discussion, we convinced them to run updates during our non-peak
times. So far we've been able to co-exist peacefully. YMMV.

Everywhere.
Smartgrid is probably the main culprit.
And without LOS, all signals get scattered by the same foliage and
other
obstacles that are scattering the signal you are trying to pick up. So
literally, the interference sources are everywhere. Sometimes I
blame the
midichlorians.

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.
