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.

 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.

        I kind of does, the way I understood it, that bottleneck limited you 
from really being able to do anything beyond what a 30mhz channel could support.

        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.

        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.

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?
