Dear Canopy guys, go talk to the ePMP guys. Please.

Hello,
ePMP provides Air Fairness. Each SM is allocated an amount of time.
If an SM is performing at a poor MCS, then its throughput suffers
because additional time is not allocated. The other SMs get their
time allocated time and do not have their time taken away at the
expense of a poorly performing SM.

If someone did make that claim then it was probably a
misunderstanding....The effect is a function of the medium and no
product can avoid it.
It's possible they reduce the effect by allocating less airtime to the
weak CPE. Basically make the slow one slower rather than making
everybody slower. *IF* they do, that's not a unique feature to the ePMP.

I dont know how they can make that claim when their "flagship" 450
product will suffer from decreased capacity when SM's with weak
signals connect to it and pass traffic. Same thing with LTE. Burns
up more airtime so why would EPMP be better than all the expensive
gear? Doesnt make sense.

It is my understanding a poor receive on one SM will not hurt
performance of the other SMs...
( i could be wrong but am pretty sure i read this on the forums )

Sounds like major interference or you are installing right
under the tower without giving the SM installs uptilt

We are having some issues with a epmp 2000 AP.
At first there was an install on a customers private
tower to get
service. I noticed the MCS downlink and uplink were
sitting around MCS
1 with 80% or so of packets. So it affected all other
customers on the
AP and brought those other customers into 20% MCS 1
levels. Now his SM
has been raised and signals are great, -60dBm, SNR of
37dB, MCS 13/15.
The SM is also operating at mostly MCS 14-15 with only
1% in MCS 1.
I changed the management to be MCS 0 to attempt to
help with the
minimal connection to MCS 1 so it will be allowed to
pass traffic at
that rate.
However, this customer still has issues where the internet
connectivity is random. Sometimes it just completely
drops when you
put traffic to it, but when it is on, speed tests of
37 Mbps down and
12 upload.
All other customers are still on MCS 1 with levels
ranging from 7% to
20%. I can assume they are having the same trouble as
the customer
listed above.
All software is 3.1
My question is, what is the issue? This SM shows
nothing but good
results, yet connectivity is poor at best, and all
other customers are
still having issues. I even disconnected the SM that
caused customers
to have problems and they were still modulating at the
7-20% MCS 1
level. Tried changing channels, etc. but still no results.
Any help would be appreciated.
