Thanks for the Reply Sakid, So on an 80mhz channel, 4500AP to 4X SM will
do around 700-800mb, so a 20mhz channel (realistically what is available
in our area due to congestion) should be around 150-200mb/s? Basically
what we see on PTP Force425 links, just in multipoint?

if that helps
sounds like it's partly an 802.11ac to 802.11ax compatibility issue
I also seem to remember someone explaining to me that the 4500 was designed as
8x8 to get maximum sector capacity with a limited channel width, whereas the
4600 is aimed more toward using wide channels in 6 GHz to get the capacity.
From that perspective, 4600 would also be better for single customer
throughput, but again assuming you are using 6 GHz. (or somehow have 80 MHz of
clear 5 GHz spectrum)

Subject: [AFMUG] EPMP 3000 Vs 4500
I was wondering if anyone has some real world results from changing
EPMP3000 to EPMP 4500. I'm starting to get equipment for our site builds this
summer, and am looking at the price difference between 3000 vs 4500 trying to
decide which route to go. I don't do high density deployments, so maxing out
capacity on a sector is not a concern. Throughput to the Subscriber is more
important. Can I get higher throughput to individual Subscribers with 4500 than I
can with 3000?[SA] Yes, you can get higher throughput to an individual subscriber
in the ePMP4X series vs the e3K SM series. This is partly due to support of 1024
QAM, far more efficient air protocol and various other changes that can push a 4X
SM to the tune of 700~800Mbps. Having said that, the e3K AP is the most mature it
has ever been in terms of all the fixes, performance improvements over the years.
The SMs at 80MHz is still pushing close to 500Mbps. As Ken mentioned earlier, the
4K story is about AP & SM capacity with support of backwards compatibility to
11AC SMs but the e3K on its own is compelling for what you are looking for.
Compatibility between 4500 and F300SM is very close to coming out but don't expect
the 300SM to have any improvements in tput. Unfortunately, we dropped 11n support
on the 4500. It was just too much to test and cover.
[SA] Now the best part - e3K Aps can be had super cheap in the NA region. I
want to say in the $300 range and I believe RF-E is doing aggressive promos on
horns as well. 4X4 MUMIMO horns that can support split sector mode.
Would it need to be a 4500AP and 4500SM, or would there be a noticeable
throughput increase from a 4500AP to a F300 SM (Future Support)? I'm guessing
my EPMP1000 SM's are EOL from talking to a 4500AP if I wanted to upgrade a site.
I'm guessing this was all covered at sessions during the WISP show, but
unfortunately I couldn't attend.
