That's very interesting Eric. Our exposure to the smart meter damage has been minimal so far. One tower mostly unusable and a couple other customers affected at other towers.
We have a ham guy blasting away at 924 near two of our towers so we had to use 906, 914, 922 for that tower (no guard zone) and it has worked pretty well. We just got our 900 gear in so hopefully we can get it on a tower for comparisons before Christmas -----Original Message----- From: Af [mailto:af-boun...@afmug.com] On Behalf Of Eric Muehleisen Sent: Wednesday, December 16, 2015 9:17 AM To: af@afmug.com Subject: Re: [AFMUG] 900 MHz 450i report 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.
