Speed limit over wireless interface on RB911/912
Posted: Tue Dec 16, 2014 10:14 pm
Dear sir!
We have P2P link with RB912UAG-5PHnD+R11e-5HacD and RB911G-5HPacD on other end.
System under load (SUT) description:
RB2011iN (GEth) -- RB911G-5HPacD ------- wireless 802.11ac (5650MHz/19dBm) ----- RB912UAG-5PHnD+R11e-5HacD -- CCR1036
link range 3 km/ signal strength Vpol -45/-49 / Hpol -47/-51 (one of mAnt 30dBi is not optimal position, i'm know it)
On link set 20MHz/802.11ac/2Ch - bandwitch maximum throughput is approx 100Mbit TCP (char's speed 173.3Mbit/s)
if we set on link 40MHz/802.11ac/2Ch (char's speed 400Mbit/s) - bandwitch maximum throughput still is approx 100Mbit
CPU usage no more then 60%
How it possible?!!!
