The only other thing I could think is to try playing with the front
sector / back sector thing. That's part of the Cambium wifi TDD sync
secret sauce. I have no idea what that does exactly, and I could be
completely wrong, but a SWAG would be something along the lines of
transmit frame spreading on Canopy. That sort of randomizes the AP
beacon frame so SMs have a better chance of hearing it in a noisy
environment, or in the FSK world, so beacon frames from multiple APs
don't clobber each other.

I assume these APs are already synced?
If it's possible to get some of them onto 5ghz, that would be the way
to go... otherwise, I'd say a 40mhz channel on one AP is worth a try.

It isn't too hard to overload the front-end in the ePMP 1k. Just like
the RocketM. I really doubt they're going to do a 2.4 ePMP 2000.
Can you try a 40MHz channel on one of the 2.4 APs and shut the other
one off? I don't know your setup and terrain, but I would try an ePMP
2k and off-load the customers with good LOS.

So we have a site where all of the customers are south of the
tower and we have a 2.4 120 degree KP Performance antenna and ePMP
AP pointing at those customers. We have put a lot of SMs onto the
AP and before it gets to congested we wanted to add an additional
AP. It turns out most of the customers are covered by a 90 degree
sector so we put up a second 90 degree sector( again KP ) �on
2.4. I think where we screwed up is we installed this new sector
with 3 feet of horizontal separating from the other sector and no
vertical separation. ( they are side by side pointed in the same
direction)

When we fired it up the SMs on the other AP started to re reg.�
I have placed one of the APs at the top of the band on 20 mhz and
the other on the bottom on 20 mhz. Its better but they still drop
and register over and over.

So my question is. Has anyone put two 2.4 sectors on the same
tower pointing the same direction successfully? How much vertical
separation did you use? I am assuming vertical is going to be
better than what I did.

How much of a guard band did you use?

The 120 degree sector is older so it doesn�t have the same
shielding on top and bottom as the newer 90 degree KP sector. Just
FYI.
