not one router, it was combined bandwidth divided to four routerboards on one side, and combined by 4 routerboards on the other. load balancing
Interesting.... More info:
1) did the routerboard have the same antenna? (I suspect they had different antennas). I know usually it is used with different antennas, but if only one "phisical antenna box" implementing 4 antennas would be available that would be a nice feature. This is because in many sites they ask for the physical room that you are using, so the smaller the better
2) 4 routerboard or 4 + 1 routerboard (4 for sending packets, 1 for balancing)
3) which card where you using and which freq (2.4 or 5Ghz) and which channels?
Thank you
