-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.

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. ----- Original Message ----- From: "Chad Halsted" <[EMAIL PROTECTED]> To: "WISPA General List" <wireless@wispa.org> Sent: Wednesday, July 19, 2006 3:46 PM Subject: RE: [WISPA] Tranzeo WDS capacity, Mikrotik - problems 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. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jason Hensley Sent: Wednesday, July 19, 2006 1:36 PM To: WISPA General List 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?
