125km or 80 miles link setup

Thu Jan 26, 2012 1:17 pm

hi all
we will have a 125km or 80 miles link using the rb435 board and the dbii f52n pro (atheros 9220 chip) cards, before we start with all the ACK timing problems and packet sizes tests, can somebody provide us with a configuration file that works over 110km (from my reading at that distance we will run in some troubles).. we have a free freznel zone 60% and all, and we did allready a 72km (45 miles) link so aiming antennas and such stuff is not our problem.
One detail, we want to get abouth 40mb troughput, so 20 or 40 Mhz should be necessary and we will use the 5 Ghz band,
thanks in advance.

Did you put in the distance under the NV2 settings?

I haven't tried NV2 on long shots, but I've got a 24 mile shot, works much better with nstreme than it does without.

Re: 125km or 80 miles link setup actually 126km

just to inform :
we finished most of the instalation and we had first a 30dbi mimo dish on
one side and a 34dbi mimo dish on the other, but the CCQ was bouncing
from 60% to 90% and data trouhgput is from 90Mb to 12Mb changing , so
we did replace the smaller dish for another 34dbi antenna, here are some pictures from the
way up and the view up there

right now we are finishing de second link with some xr5 so that we can do nstreme dual , the testing looked ok , but i am a little disapointed about the speed the link budget was made for 200 mb but when we are lucky we get 90mb
and still the only protocoll which works is nstreme no NV2
