Our power company is also using 3.65ghz Wimax as part of their smartgrid
system. Sounds like it is a backhaul to their 900mhz stuff.
They don't have any authentication on their Wimax system (I presume they
limit network access by other means), so we tripped over them when some
CPE connected to their BS and the customers called us because they had
no internet access.

GE MDS is pushing 3.65 SCADA allot

George, is this due to some weird weather by you?
Oh, and one thing to consider if you have 3.65 interference, I found
out ComEd is using 3.65 WiMAX for smartgrid, I don’t know if this is
the top of the hierarchy for their 900 MHz stuff, or SCADA to
substations. One tower by me they have 4 sectors and I think each AP
only feeds 1-2 CPEs. It didn’t help that they totally messed up the
lat/lon of their tower when they registered it in ULS. Once I looked
at the CPE locations and drew lines following the stated azimuth, I
saw they converged on a tower next to a ComEd facility.

lol well it wont be coming from us for a while, we are going 3ghz

Dude, I'm seeing multipath and ducting like a somebitch. Started
around dusk. Don't beat your head into your desk. I'm seeing some
11GHz links go from their nominal -45ish to like -35 to -60 in just a
couple minutes, and BER alarms like crazy. This is teh suck.

There is some nutty madness going on on a large portion of our 320
network, it has hit multiple sites at once.
I know much of its self induced due to too many marginal installs on
very limited access points
good CINR to SMs, even matrix B I cant even get into to manage.
uplink MCS for the most part looks good until i get into the frame
utilization, tons of 16qam 1/2 and 100% usage with only 6-12 mbps
throughput
I have been shifting frequencies across the network because it
presented like interference, and a change on one AP results in
required cascade changes across the 3ghz network since 320 sync
doesnt actually work.
APs are basically default layer 2, no profiles changed, 7mhz
channels mostly ABCD 90s and some split APs. sub counts range from
10 to 35
I migrated a distant part of the network to 10mhz channels and am
not seeing this issue, but subscriber counts are low
Im at my wits end on this nonsense and am about to just put every AP
on the network in SA mode to get a visual on what my spectrum looks
like
we did turn up a 450 facing southwest ten miles south of another 320
AP thats facing south, it blinded the SMs to the 320 on a near
channel even though they were only in the back lobe, but this is far
from the others
any advice from you other guys stuck with wimax would be appreciated
