We have been blocking torrents as a network protection measure
for over 6 years using various DPI and behavioral detection
systems, and its in our AUP. We have never lost a customer or
even had a complaint because of it.

Rory, how do you “kill torrents”? technically,
And, aren’t there a lot o legitimate programs that use
torrents as the distribution method?

If you have file sharers on there for example, I’ve seen
XM radios drop to 10Mbps or less (another reason we kill
torrents). If you watch the modulation levels when that
happens, you will also see them drop as the CPU load goes up.

To prove my point further, if you do throughput
testing with Ubiquity in ptmp mode, you will find
with xm radios, cpu load affects modulation
levels. I haven't tested xw radios yet but I
believe the threshold is just higher and probably
justifies 30mhz but it's going to be close.

The pps and cpu load absolutely is another
variable you need to take into acount, especially
with 400 and 526mhz atheros processors that are
also running polling. Ignore it as part of your
overall strategy and you could be wasting
spectrum. If your ap never exceeds 80mbps, why
do you want 30mhz channels. Sarcasm aside, does
that help you understand my point.

I think we are having two different
conversations, and I have no idea what you are
talking about right now.
What we were discussing has to do with channel
sizes, epmp, and ubiquiti. In particular, why
UBNT 40mhz isn't any better than 30mhz in terms
of efficiency.
This part of the discussion has nothing at all to
do with any theories on PPS you may have, other
than those you have tried to inject into this
discussion.

I can assure you that on radios connected in a
ptp config or small ptmp, that you will see more
throughput on the 30mhz channel given a noise
floor of -97 and signals in the mid -50s, even
with nothing connected on the other side of the
radios.
Its an efficiency issue.

Now that I think about it, I have seen 40mhz
perform better than 30mhz... but yes, that was
because of RF problems, and neither one was doing
anything close to what it would with a good link.

The limitation on the older xm radios was pps.
When you added a lot of small packets and airmax,
you could drop down to as low as 40Mbps. In the
real world in ptmp mode. We planned for 50mhz per
AP with eveything g taken into account.

I don't know how epmp does it.
For UBNT, a 30mhz channel is just a "fat" 20mhz
channel in the atheros chip. Single operation.
For a 40mhz channel, it's really two 20s,
meaning radio operations are ran twice. Loss in
efficiency, also marred by the lack of gigabit port.

I'm not sure how much applies to ePMP - they do
have a much a faster processor and on a software
level they are very different.
So far, I have been running all of our ePMP APs
on 20mhz channels and PTP links on 40mhz or
20mhz, depending on how much capacity they need.
I haven't really seen much need to go down to
10mhz channels with ePMP.

I'm not that familiar with the ePMP's yet but I
can tell you some things that we saw with
Ubiquiti. One is that channel width does not
scale with bandwidth that that Atheros chipset.
For example, 40MHz channels rarely hit their
theoretical maximum due to a variety of factors,
noise, lower s/n, processor limitations, etc...
Second, 20MHz channels seem to be the sweet spot
but even with GPS sync, you have to deal with
reflections. Third, 10MHz channels have more
overhead as a percentage of total capacity and
don't handle a lot of users well (above 40 for
example with the older 400MHz chipsets. I'm
starting to deploy XW radios with the 520MHz
processors but everything is 20MHz now so I don't
have a comparison). We did see peaks of 32Mbps
with some customers on 10MHz channels but that's
non-peak times. In peak times, we were seeing
8Mbps when more users were online.

We have deployed 6 towers to begin our new EPMP
network and 4 of those towers have a full cluster
of 2.4 90 degree EPMP sectors. They are
configured with ACS turned off now because in
several cases they all ended up on the same or
very close to the same channel. I have Front
back designations and non overlapping channels
set up on all towers. I have tried 40 mhz 20 mhz
and now 10mhz channels and while the customer
stability has gotten better the more I play with
settings I have kind of hit a point I dont know
what else to try. I have some that the uplink
quality will vary wildly from 100% to 0%. Most
have gotten better since I went to a 10mhz
channel. Most of the customers get 12MB -30mb
down in the wireless link test but the uplinks
are as bad as .17. What is the cause of this poor
uplink quality? Is it interfernece? My one 5ghz
AP does not have this problem but even with noise
many of these customers have -50 signals and
oddly enough the ones with the great signals seem
to be the ones that have the poorest link tests
on the up link side. I also have customes with
-65 or -72 signals that get 5MB up on the same
sectors? Im scratching my head a bit on what the
fix is for this? Should I leave ACS on and change
everything to 10mhz channels? Will a full cluster
with ACS on work all on the same channel?
I'm used to FSK where you pick your channel and
any channels that are adjacent will cause
problems with connected SM's. So am I just
applying old knowledge to a technology that it
doesn't apply to?
