Hello, I suffered for a long time, of a probable interference between two nodes.
These two nodes are in a mountain were a lot of rf emissions are present ( tv radio etc. )
The nodes are composed of RB33+Xr5 and a 90cm parabolic dish; these are ptp connections of about 25km each.
About one month ago the two links becomed instable, hig latency, tx/rx ccq was fluctuating from 90% to 10%, I am using turbo mode and the pthrougput
was from 55mbit to as low as 700Kbit!!! A couple of days ago I discovered that if I disable the radio of link A, then link B tx/rx ccq in a short time rises to 90/90,
after re-enabling link A, then link B decreases to as low as 20/30. I made a lot of checks, changed both the radio cards, the parabolic dish feeders, changed frequencies but the problem still was there, my last change was enabling nstreme and VOILA’!!! The problem disappeared, both links are around ccq 100/100 with a pthrougput of 55Mbit, incredible! Now I am asking to you WHY nstreme cured a probable interference; I know that nstreme combines more data packets in a big one so it doesn’t changes anything in the wireless section of the link, is it thrue?
Thanks for your help
regards
Alessandro
nstream will not cure interference. Actually it is not recommended to use nstream if you have high interference. However, it also relaxes the ACK response timing in 802.11 wireless links. This is needed for longer distance links(over 20km) and probably what fixed your assumed interference problem.
