We have a couple of p2p dishes on a mast we share with a operator that has some airspan 5.8ghz wimax kit. We accidentally put nv2 using sr71 cards on same channel and we didn't notice any problems on our link in fact we were getting well over 100mbps but it killed out their wi-max service :-0

I don't think NV2 killed their link, interference in general did.

On the same channel as the other operator ? , so much for a frequency usage scan to check for a free channel
Sounds like they don't have good RF screening for co-location interference which is very important on a shared mast.

nv2 is aggressive protocol
I have experience with my competitor
my SXT was about 1.5m away from there equipment (I think they use some linksys on 5ghz but I m not sure it was inside the box)
when nv2 was on competitor link was drooping down, I use channel 5520Mhz they told me there channel was 5700Mhz
when no nstreme no nv2 was selected they have no problems
I moved my SXT 15 meter but they continue complaining but I dont care anymore because I use legal freq. with legal output power

I can in part agree with Lakis. I've also experienced few times that enabling nv2 on AP effectively kills that channel for neighbor AP's. And I don't think it's interference, because everything was and is operating perfectly with nstreme.. Some time ago I read some post or article explaining why could this be happening, but I can't seem to remember where..

SXT next to ns5m, same channel, ns5m can't transmit even ping.

NV2 maybe aggressive but as we all have experienced it has its shortcoming with disconnects due to little or no RF Screening and high latency, when there is issues with co-location interference it can be caused by little or none RF screening on both the sectors and PTP links, another consideration is radio cards bandwidth will be 10/20/40Mhz during transmitting but on receiving the bandwidth can be very wide and a lot wider than just 100Mhz
