Well, that’s 10 times what you can do with PMP100 in 900 MHz.
If all your customers are 3 walls and a parking lot away, you’re off to the
races.

I was getting between 30 and 45mbps aggregate on a 10mhz channel, across our
parking lot, and through three walls... which is pretty much meaningless, other
than to say it's better than PMP100 :P

That's impossible to answer without knowing what SNR you will get, what
channel size you will use, what up/down ratio you choose, and whether you will
use 2.5 or 5 msec framing.
If you can use a 20 MHz channel and can get 30+ dB SNR so you can run 8X
MIMO-B, then throughput will be like any other 450 variant somewhere north of
100 Mbps aggregate up+down.
More realistically for the 900 MHz band, you might use a 7 MHz channel and
get 4X to 6X modulation due to interference. You can do the math, that's
somewhere around maybe 25 Mbps.
If your interference is mainly from high powered paging above 930 MHz, there
is a paging filter that might help.
I didn't check Link Planner, if Cambium has put it in there, you could play
with the numbers.

What's the real-life throughput of the 450i?

What is the status on the 900mhz 450 hitting mass distributors? I know some
people out there have some early pre-order units but is there some of this
still floating around on a boat somewhere or something? Streakwave doesn't even
have the 900mhz 450i listed on their website at all. Also more importantly, how
good is the F/B ratio on the cambium sector in real life deployments? The
sector looks like a KP on the PDF. Have they released any pricing publicly?
Also will there be a lite AP for <10 subs at half cost of the full AP? This is
very important because we need to have many sectors on a tower to get around
the noise which means a lot less subs per AP.
