Hi,
I'am a wisp in Austria, running the network with 100% Mikrotik Clients & APs, around 50 Terabyte per month transported. I have Wisps since 2000 ...
It's a very noisy environment here, we're using 100% nstreme protocol for all sectors as this gives us the best results. It would be pleasent to see nstreme stability & speed improvements.
--- tipps for the others here:
We have partly fixed the nstreme disconnect problem by disallowing speeds with low reduncy coding.
MCS 7 or MCS 15 have very little forward error correction information, when you disallow them everything gets more stable & the average throughput is higher. We usually also disallow 6, 9 & 12 Mbit & MCS 0, MCS 8 in order to speed up beacons and overhead transfer - if a link can't handle 12 or 18 mbit you better disconnect the customer anyway.
band=5ghz-a/n basic-rates-a/g=12Mbps,18Mbps,24Mbps,36Mbps,48Mbps,54Mbps
ht-basic-mcs=mcs-1,mcs-2,mcs-3,mcs-4,mcs-5,mcs-6
ht-supported-mcs=mcs-1,mcs-2,mcs-3,mcs-4,mcs-5,mcs-6,mcs-9,mcs-10,mcs-11,mcs-12,
mcs-13,mcs-14,mcs-16,mcs-17,mcs-18,mcs-19,mcs-20,mcs-21,mcs-22,mcs-23 hw-retries=15
Also its very whise to isolate the sectors on the sender from each other. no antenna should hear the neighbor better than -50 dbm, ideally less than -60 dbm in order to hear your own customers and not only the neighbor sector. if your neighbor sector is received with -30 dbm you shall not wonder why you get customer disconnects ....
we use camping aluminium cooking pots for that (if you use a sxt sa or a sxt hg as a 24 degree "sector"), or try to mount sectors on different sides of buildings with the building in between.
