-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.

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.

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'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!
