If you're running the 3GHz 450 with no guard between channels, you need
to enable adjacent channel support on all sectors. This instructs the
SMs to never exceed 23dBm Tx power.
As far as co-channel, aka back-to-back sectors, if you have a REALLY
close SM, it's possible that the opposite sector will hear that SM and
trigger LBT. If that's the case, I would think about doing a 5.4 AP for
those close subs. I haven't ran into that yet and I'm doing -57dBm
combined SM Tx power control on all 450 sectors.
I agree, I think the 3550 rules are going to suck for us. We'll probably
end up seeing carriers trying to do small-cell stuff with it.

We are using 20mhz channels with ABAB.
However with LBT you have to offset the A1 by a cpl MHz from A2 etc.
Think they fixed that issue in one of the early betas, remember
running into it shortly after hardware release. We are doing ABAB and
not running into it now.
Also don't worry about the band changes. Currently this equip would be
grandfathered for 5 years.
Does that mean 4 years from now you can still add SM's to an AP under
old rules? My concern is the new band seems to only come in 10mhz
chunks. Right now with perfect connection on 20mhz channel we get
80mbps down. Not so perfect connections 30 - 40mbps down and lets not
even talk about a poor connection. Drop that down to 10mhz channel
and that's not a lot of bandwidth for each sector.
Works great!
Are you using 10mhz or 20mhz channels? We currently use 20mhz
channels in ABAB format. I worry about the future band changes and we
wont be allowed to do that anymore. Customers keep wanting more and
more bandwidth.
What kind of luck is everybody having with the 3.65ghz 450 gear?
