I went out with a PG&E technician that had a special scanning tool that
connected to the mesh. It showed all the local smart meters (hundreds
and hundreds through the hub we were looking at).

what do you use to "see" the signals? Most FHSS move so fast Airview
doesn't catch it very well.

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

across western Kansas and they all run a version of Landis

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

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.
