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 https://dl.dropboxusercontent.com/u/1578608/Public/smart_meter.jpeg)
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.
