Thanks for all your posts on this problem. I finally got the tower owner to shut the other guy down until he switched to another frequency for clients and bh. I will let you all know that his equipment was about 20 feet below my accesspoint. It did make a difference on what channel I was using but it wasn't affecting all clients the same. Some of the clients would show nothing for signal and you could reboot them but it would only show a signal for a short time. I have clients within .5 mile that would have this problem and others that were 5 miles out still working but very slow most of the time. If you tried running on a channel close to them I had zero throughput on the tower. Most of the problem was upload from clients to ap and it is very strange that it causes the client equipment to lockup and lose signal completely. This makes canopy very dangerous. I tried a testing throughput to one of the clients using a 500 byte ping with zero success while the canopy 2.4 backhaul was plugged in and just as soon as I would unplug it every ping would go through perfect at around 20 ms I would then plug it back in and about 30 to 40 seconds later all pings were lost. This backhaul unit was pointing the opposet direction of the client I was running this test on and was about 20 feet below my ap. Do to the card in the ap and the brand of client equipment I'm using I couldn't try using nstreme or 5 mhz channels to see how it worked. I will be changing over to sectors in a few weeks and getting rid of the amp. I've meant to do this for some time. I am also going to be deploying 900mhz at this location and that is what he is going to be using now. I will be using xr9 and they are using cyclone gear so I will test and post how other methods work once I have this up and running. Thanks again
900 Cyclone gear on the same tower.... will not work. I run sectorized and a provider co-located on the same tower... the cyclone stuff is HPOL and I use HPOL. The Cyclone was 906 and I use 922, 917 and 912 / 120deg sectors. If they go full power, 912 is dead, 917 and 922 client upload is chit. We also used DCC filters at center channel 5.5Mhz wide. Without the filters 912,917 and 922 did not move traffic. I tried the XR9 with the same results. You are getting about 20ft. vertical seperation... which is about 10ft better than me.
Let me know what happens with you.
