Ok, So DFS?
If your antenna/dish gains are set correctly in each link at each end
setting correct power level should be a breeze.
Reflections from your own link can cause events to occur if this is not
set correctly. Also, Ensure there are no other overlapping links or
nearby radios on the same or near channel.

This is interesting. I definitely want to be in compliance, but I also
know that these detection are 100% false. We have redundant AP's on
the same tower mounted at the same height pointing the same direction,
but 20mhz apart, and they don't trip DFS. It's like there is a magical
packet or multipath event that causes this. We may have to give 15.0.2
a try.

I’ll vouch for Sean’s experience on these – we also had to roll
back a bunch of DFS 15.1-15.1.3 APs to 15.0.2 to deal with a
ridiculous level of false radar detections. I haven’t yet tried
15.1.5 on any of those, but there wasn’t any indication they dealt
with that in release notes.

15.0.2 is the least finicky with DFS. above that cambium changed
the code to be more restrictive to meet new FCC rules (or
something like that)

If someone has the holy grail on what firmware for reducing DFS on
450. I'd love to hear it. We are on 15.1.1 and the false DFS hits
are killing us lately. See attached. This is one AP for the past
couple days. It's been terrible around here.

For ePMP it depends on the version number. 2.6.2.1 had very
stable DFS performance and for APs where we saw issues, we
have left
it there. Some links are working fine on the latest firmware
though.

My experience is exactly the opposite here. ePMP seems more
sensitive to DFS events. By far.

Anyone noticed that apparently the Epmp radios are less prone
to DFS events? Im assuming most are false caused by RF
interference, but I see way less events on Epmp than on 450�
Will have to do a side by side study.�
