Right....IMO the number of subscribers the thing can efficiently handle
is basically irrelevant because you'll run out of capacity before you
hit that number. That's probably true with a lot of stuff these days.

We have ePMP AP's with 55 subs that are doing just fine. Probably
won't load any more on it due to high downlink utilization during peak
usage.

Over 20-30 subs not recommended by whom?
When I talked to Cambium about subscriber density, they said they've
tested with up to 120, but suggested keeping it under 65. I do have
an ePMP AP with 43 SM's at this point, no trouble that I'm aware of.
It hits abou 60% air utilization at peak times.

Your biggest difference is your throughput per MHZ your epmp will do
less bandwidth in a 20mhz channel than a 450. he other big difference
is subscriber density. It is not recommended to go over 20-30 subs
per AP on epmp without loss of performance. I regularly see 450 APs
with 70+ subs per AP. With Medusa I have seen over 130. As far as the
Medusa not being field proven you may not have field tested it yet,
but I know for a fact it has been tested and running on networks for
some time now and a viable solution.
If you have any more questions feel free to hit me up off list.

Since framing will be slightly different and so will processing

The stds based radio gets close to mimicking the
450 series but thats strictly based on Cambium magic. Capacity and
sustained rates per VC is the where you will see a difference.
Latency will be very consistent from ap to sub. PMP450i is where its
at.

if im running 75/25, epmp is roughly 87mb capacity, 450 93mb
capacity
is this correct?
are efficiencies batter on 450 if installation is the same? ie, if
I
forlifted one AP with 17 epmps to 450, where would my gains be
assuming everything stays installed in the same spot. Its not like
the
FCC gives 450 any more power than epmp, so path loss should be the
same.
Im looking at this epmp 1000 sector thats running overall about
64-7%
efficient with 17 subscribers and wondering what the gain is to
move
to 450 (exclude medusa, as its not field proven)
