I forgot about that, and I missed the presentation.
That's 450m right? How much capacity did they claim on that?

With the Cambium PMP450 I monitor the framelink utilization via SNMP
to determine if an AP is oversubscribed or not. I have 25 subs on this
ap and it peaks at about 25% utilization on the downlink every night.
Customers are a mix of 1.5Meg / 3.0Meg / 6Meg download with up to
20mbps bursting. At this rate I would safely say I could put 75
subscribers on this AP but it really is dependent on who your
customers are. I have a similar AP only serving 15 customers that will
hit 50% utilization sometimes. Apparently the customers in that area
must watch more Netflix, lol.

For planning purposes, I assume we'll get 2/3's of advertised
throughput
from the AP and then plan on 8:1.
In real life you have to abandon the over subscription rate after
the
planning phase and monitor what's actually happening on the AP's.
Averaging hundreds of users together you'll get actual usage that
seems
in line with an 8:1 or 6:1 ratio. On an individual AP you tend to
not
have enough capacity for more than 30-50 people, so you can easily
get a
few statistical outliers in the mix that make actual consumption not
line up with the planned over subscription rate.
It goes both ways too....I've seen sites with actual over
subscription
of 20:1 and everything's working ok, and other actual sites fall
apart
when oversub was only 4:1.

At what level do you over subscribe your APs? 4:1? 8:1? 15:1? Or
something else?
Thanks
