George,

Lots of near line of site on this location. We used it to offload old
900fsk. Ill put up 5ghz but not until summer when leaf cover is in full
bloom.

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.

Thanks,
