Well, Cambium hasn't given us a frame calculator for ePMP. The only
thing available is the ePMP/FSK co-lo tool, but that's for 20/40MHz and
2.5ms only. So apparently we just have to guess.
A 450 configured at 20MHz, 75%, 5ms, 10 miles and 3 control slots, AP Rx
start = 36112. 5MHz = 33553. Not even close.

It's actually for an existing sector. There is a nearby wireless
router that is out of our control that is on the same channel as the
AP in question.

Run a frame calculator. 20 vs 10 vs 5MHz with the same settings do
not line up. In the ePMP world, I think the only thing you can do is
mess with the max range a bit since all you get is 30/70, 50/50 and
75/25 TDD ratios. And obviously you need to be on the same frame
duration. If you're running the 20MHz sectors at 2.5ms for timing
with PMP100, then another sector on 5MHz/5ms isn't gonna play nice.
I really pisses me off that I can't do 2.5ms framing on 5 and 10MHz.

I don't think channel size changes the rules of sync - you need a 5
MHz guard band, time them, face different directions.
If the three APs are each on 120* you should have no problem, though
I don't believe any of the sectors have good enough ftb to frequency
refuse (assuming the 5 MHz is the same space as 20 MHz).
If the three APs are using different frequency space with a 5 MHz
guard band you're fine.

Are there any sync problems associated with running APs with
different channel widths with EPMP? For example, if I have a
tower with 3 access points and 2 are set for 20 MHz wide channels
and one is set for a 5 MHZ wide channel will that cause problems?
