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.
