First - sorry for the double post of this topic in two different Mikrotik forum locations. I was not sure where the best place was to post on this hardware topic.
The full topic is in the Wireless section at : http://forum.mikrotik.com/t/what-is-the-absolute-fastest-wds-throughput-possible-with-mikrotik-ros/103760/1
Summary - I am looking for faster hardware to build some WDS links to achieve a sustained greater than 500 meg throughput networking loads and keep the propagation delay low.
Possibly using non-Mikrotik mini motherboards but still running ROS with Mikrotik mimo 2x2 or 3x3 AC NV2 WDS microwave links.
