Re: [WISPA] VoIP, Asterisk Scale

2006-07-25 Thread Matt Liotta
We have found Asterisk doesn't horizontally scale. Therefore, your  
choice is either to vertically scale and/or to specialize certain  
operations onto different machines. However,  I do agree with Peter  
in that Asterisk will certainly scale for most people's needs.

 tack this amount on to the subscriber's installation fee and then

 try to make a profit on the additional work performed by the

we're banging on the door of 300 subs (gotta get off our asses and get that 
477 done so I know for sure...).


We're hard to gauge.  Many of our customers are home based businesses. 
Farmers.  They sign up personally but pay with a company check.


Talking traditional business, near as I can tell, we're around 70/30 
res/bus.  That ratio also holds up pretty well for our fiber.


One interesting thing that has really surprised me.  I thought that once the 
businesses got broadband, most employees would want/need it at home rather 
than dialup.  That's NOT been what happens.  If people have broadband at 
work they seem to be LESS likely to get it at home.  That changes some if 
there are high school kids at home but not too much.

Subject: [WISPA] Tranzeo WDS capacity, Mikrotik - problems



I've got a two AP WDS setup with Tranzeo TR-6000's with PacWireless 13db
omni's on each.  They are less than a mile apart.  Any idea how many CPE's
can run on each AP before it starts causing issues?  We're going to be
replacing the WDS setup with an actual backhaul soon, but just haven't
gotten it done yet.


I tried using a single ap as a repeater for my first site.  Heck, 11 megs 
and I only had 1.5 coming to town, what's to loose


Didn't work out that way.  The stability was horrible  Believe it or 
not, 10 customers was more than it would support.


Admittedly this was before WDS so I don't know how much/if that will help. 
But since that day I've NEVER built a single radio repeater site.  It's also 
why I don't believe that mesh will ever work well when there's only one 
radio at the node.


This gear just doesn't like to send and rec. on the same port.  It wants 
data coming in on one and out the other.


For 10 subs I'd not worry about a real backhaul.  We've done really well 
when using a client radio at the repeater site talking to the ap upstream. 
Then put in a swx and another ap, change channels AND essid and off you go 
again.  Supposedly you'll see a 10 to 15% throughput drop from doing that 
but we generally seem to see more like 30 to 50%.  I don't worry about the 
speeds till we drop below 1 meg though.


For more active sites I'll either put in a ptp link or, these days I'll run 
a high end 5 gig ptmp system and feed business customers and the wifi towers 
with that gear.  It's a model that's working really well for me.




I'm having trouble with performance.  Works fine for awhile and then it
seems to bog down, and then back to normal again.  I've got about 10 
clients

(all  Tranzeo gear) on each of the AP's.  I wouldn't think that this would
cause issues but I may be wrong.  Signal between the WDS connections is
around the -65 mark so that's no problem.  I've got a couple of marginal
clients (running -90 or so) so I'm wondering if these could possibly be
causing it. Everything is horizontal pol.


All gear is a bit different.  But for wifi gear a -90 is WAYY too low. 
For the newer gear I'll go as low as -80 but that's about as good as it 
gets.  Anything over -65 is too high, you'll be much more likely to pick up 
multipath at the ACK level (all the really fun stuff happens at 1 meg so is 
often at the -95+ level).


I like my most sensitive radio level to be less than 30 dB below my signal 
level because most multipath that's a skip off of roads, cars, roofs etc. is 
around 30 dB or less I'm told.


Build a ballanced network.  Not too hot or too cold.  For today's wifi gear 
that means a proper signal level is from -75 to -65.  Yeah, sometimes you 
have to go outside of those, but the cases are very limited and certainly a 
last ditch kind of thing.




When the service completely drops out I can get to the AP's just fine from 
the client end, but can't get to the router (RB532).  I've switched out 
cabling, switches, etc with no luck.  Have a new 532 on the way so I'm 
going to switch it out as well and see what happens, but anyone have any 
other thoughts?


So, what feeds the first ap?  As I understand it you can't get to the noc 
right?  How far from the noc can you get?


Might want to call me and we can walk through some of this quite a bit 
faster via the phone.  Outages aren't well handled via email much of the 
time :-).


Also, you said you've surveyed the area.  Is that with a real spectrum 
analyzer or just netstumbler or some such tool?  Nothing short of an 
analyzer will give you the data you really should have.  Though there are 
some ways to interpret the signal quality data on today's wifi radios to get 
a bit of an idea.




Also, anyone have experience with an X10 camera shutting down their 
network?


Hasn't shut us down but sure could.  They are always on, use almost the 
whole band and are very powerful transmitters.  I do have an ap on a 
building that's got a wireless security system in it.  I'm gonna buy the guy 
a wired system as soon as I can cause his wireless stuff causes some 
stability issues for me.

If you haven't run a test with a spectrum analyzer, there really is no
way to know for sure what is out there.  Harmful noise, as you probably
know, can come from all sorts of devices, not just 802.x APs.

Yes, -90 is bad for several reasons.

1.  That link is probably suffering from high packet loss.  This will
not only cause problems for the customer's link, but will keep your AP
busy resending dropped packets.  One customer isn't going to overload an
AP, but several could.

2.  -90 doesn't leave much room for fade.  Bad weather could, and most
likely will, knock this link out in a heart beat.

3. The rate at which the client and AP talk at a -90 would be 1MB.
Whenever the AP is talking to the client it will have to adjust its
rate to match that of the client's.  When another client, let's say it's
connected at an 11mb rate, wants to talk the AP has to adjust its rate
to 11mb, these constant adjustments can cause latency, dropped packets,
and overload the CPU on the AP.  This is more evident with the more
clients you have.

Always set your AP rate to auto, hard set all clients to 11MB.  Just
make sure you don't do the install unless it will support an 11MB rate.
Lastly, I would suggest that you test each and every link for packet
loss sending large packets, 0% or less and you'll be good to go.

I could be way off; your -90 client may be working perfectly.  I just
thought I would share some info that I had to learn the hard way.

Good Luck!!

-55 if too high.  With your trees instead of buildings you might be ok most 
of the time.


Remember, all of the handshakes, ack etc. happen at the 1 meg speed. 
Sensitivity there is usually around -95.  Multipath is usually 30 or more 
below your main signal.


So, worst case you want a -65 signal with -95 noise (in this case the noise 
is mulitpath).  You can cheat that some but at your own risk.

-90 is not just bad, it's horrible. ;-)

It has been my experience that a signal of -75 or better
*should* allow for a reliable 11Mbps connection rate. I have
seen times when the subscriber had a -65 to -60 and they
would only associate at a rate of 1Mbps but after changing
channels, their association rate was able to negotiate at the
optimal rate of 11Mbps. We also have a subscriber with a
-89 and they have been able to sustain a constant 11Mbps
rate which blows my mind. They are one of our happiest
subscribers and since we have not noticed a degradation in
service/speed from the AP to which they are associated, we
have left them connected. I will be testing a 400mw 2.4GHz
CPE at their location in the near future. Right now, they have
a 18dBi CPE with a 24dBi grid and they are connected to
a 13.5dBi H-POL sector and 18dBi radio which is 7 miles
away. They use to have a -75 I think it was but the trees
around the halfway mark between the sector and them have
since then grown into their link's fresnel zone.

We service rural Central and Eastern Kentucky and I would
say our noise floor is around -95 to -90 in most areas. We
always use the largest antenna approved by the subscriber.
If we can get a -75 link with a 13dBi panel, we normally go
with a 19dBi panel so we can get the signal into -60's. Just
try to keep your signal level in the -75 to -55 range and you
*should* do well with 2.4GHz. I can't wait until the day when
we can deploy 5GHz CPE for the same price as our 2.4GHz
CPE. But, as time goes on, I'm sure 5GHz spectrum will
someday be used the same (if not more) than 2.4GHz and we
will all be looking for the next best piece of spectrum to utilize
for our PtMP links.

RE: [WISPA] Tranzeo WDS capacity, Mikrotik - problems

2006-07-25 Thread Chad Halsted
The idea is to not do the install unless you can maintain a reliable
11mb connection (usually -75 or better) that passes the 0% loss rule.
So, having done that, you shouldn't drop customers.

Or at least that is what I have been taught, I could be misinformed. :-)

We almost never hard set any radios to any speed.  I'd rather have the 
system slow down than drop customers.

If you haven't run a test with a spectrum analyzer, there really is no
way to know for sure what is out there.  Harmful noise, as you probably
know, can come from all sorts of devices, not just 802.x APs.

Yes, -90 is bad for several reasons.

1.  That link is probably suffering from high packet loss.  This will
not only cause problems for the customer's link, but will keep your AP
busy resending dropped packets.  One customer isn't going to overload an
AP, but several could.

2.  -90 doesn't leave much room for fade.  Bad weather could, and most
likely will, knock this link out in a heart beat.

3. The rate at which the client and AP talk at a -90 would be 1MB.
Whenever the AP is talking to the client it will have to adjust its
rate to match that of the client's.  When another client, let's say it's
connected at an 11mb rate, wants to talk the AP has to adjust its rate
to 11mb, these constant adjustments can cause latency, dropped packets,
and overload the CPU on the AP.  This is more evident with the more
clients you have.

Always set your AP rate to auto, hard set all clients to 11MB.  Just
make sure you don't do the install unless it will support an 11MB rate.
Lastly, I would suggest that you test each and every link for packet
loss sending large packets, 0% or less and you'll be good to go.

I could be way off; your -90 client may be working perfectly.  I just
thought I would share some info that I had to learn the hard way.

Good Luck!!

Interference really isn't much of an issue here.  There's one other WISP
and
we work pretty closely together to stay out of each other's way.  We've
analyzed the area and nothing else is out there but us and the typical
home
APs.

So -90 is that bad huh?  Guess I may need to rethink those two installs.

No personal experience on the X10, but from what I here, it will give
you nightmares.

Seems like I heard Marlon speak such wonderful things about the x10
before, eh Marlon?

-90 signal is never a good thing.  We won't do an install unless it's
-75 or better.  Sometimes even a -75 isn't strong enough to combat all
the interference we have in town.

I've got a two AP WDS setup with Tranzeo TR-6000's with PacWireless 13db
omni's on each.  They are less than a mile apart.  Any idea how many
CPE's
 can run on each AP before it starts causing issues?  We're going to be
 replacing the WDS setup with an actual backhaul soon, but just haven't
 gotten it done yet.

 I'm having trouble with performance.  Works fine for awhile and then it
 seems to bog down, and then back to normal again.  I've got about 10
clients
 (all  Tranzeo gear) on each of the AP's.  I wouldn't think that this
would
 cause issues but I may be wrong.  Signal between the WDS connections is
 around the -65 mark so that's no problem.  I've got a couple of
marginal
 clients (running -90 or so) so I'm wondering if these could possibly be
 causing it. Everything is horizontal pol.

When the service completely drops out I can get to the AP's just fine
from
the client end, but can't get to the router (RB532).  I've switched out
cabling, switches, etc with no luck.  Have a new 532 on the way so I'm
going
to switch it out as well and
