So Marlon, using what I perceive to be your ideas below, it's not too bad of
a deal to put a "marginal" customer on (maybe not at -90, but maybe -80 or
even -85, or do you think -85 is not even good enough?) so long as we have a
clean link and we can make it with next to no packet loss?
In my situation, I'm selling mainly 512kbps connections. I have a few that
want a full meg, and one that may be looking at 3meg shortly, but I've got
mainly resi customers at the moment. I'm finding though, that I can beat up
on DSL pricing for businesses here so I'm starting to hit that market a
little more. But, I need to be sure my system is stable before I really get
into this.
I appreciate everyone's feedback on this topic. I haven't figured out my
issues completely from my original post, but they have actually cleared up
somewhat. I'm starting to actually wonder if I have either a bad AP, or if
I have water issues as it seems like it was acting up in the middle of the
afternoon, and then again later at night. Beyond that, we have good solid
consistent ping times (5ms or less) to all clients (yes, even the one with
a -90). But, again, haven't had any problems in about a week.
Waiting for it to cool down a bit before we put in our backhaul (this POP is
on top of a water tower).
Which brings another question, how high from the top of a water tower would
you recommed mounting the antenna? It's a PacWireless 13db Omni-horizontal.
It's a "cylinder" tower. Right now the antenna is mounted directly onto the
ladder railing on top. We're going to raise it up 5' or so when we put in
the backhaul too. I'm thinking that may help keep things clean too, as well
as give me just a bit more range with it (one side is partially blocked by
the "dome" on the top middle of the tower).

That's fine if you have enough potential customers to saturate your ap's
at the 11 meg speed. Out here we'll take anything we can get. If it
slows down to 1 meg for a customer that's still much better than his
dialup was.
We have VERY few customers that get less than 1 meg of actual speed. Even
in high interference zones that have 40ish users per ap. Got some folks
in an area that are below the main omni beam that only get 600ish, but
that same system will deliver 3+ megs further out or up a bit higher. Go
figure.
As cheap as ap's are getting we just keep sectorizing out to smaller and
smaller customer groups. That's helping a lot of things.

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 see what happens, but anyone have any other
thoughts?
Also, anyone have experience with an X10 camera shutting down their
network?
Thanks!
