That sounds like complete malarkey to me. I’m sure cambium would like to hear
about that as I’m happily running all my 450i sectors in some areas at 10 or
20mhz.
I was once told by an well-schooled rf engineer that 900mhz required frequency
hopping to be legal.
If your power is correct and your OOBE isn’t too high than they are just
blowing smoke. You might want to rent your own spectrum analyzer just to be
sure you aren’t bleeding too far with the edges. The M900 runs pretty dirty for
sure.

We had an issue this week where we had a Power company have a 50K licensed band
at 901.152 Mhz for power meter reading. We have still a few older links that
are 900MHz on Yagi’s to individuals in deep woods. I had to move channels all
over the place as a 902-912MHz 10Mhz channel with UBNT does not have edge
filters that don’t pollute down to 901MHz. So moving to the middle of the band
cleaned up the noise on their license.
Now they are claiming that 10MHz channel width in the 900MHz ISM band is
Illegal. That the channel width is to be no larger than 8MHz. I have read all
kinds of ISM docs from the FCC and I see no mention of max channel widths.
They made mention of talking to the FCC if we didn’t fix the issue.
Proof they are wrong any one? This is a national company with a $10K Anritsu
analyzer they hired in to find the noise.
