aggregate throughput with hardware scheduling

I plan to use a cmm with 6 ap to feed some sm. On sm side i have to upload images from camera. I read in the manual that the aggregate throughput is 6.8 mbps with a 10 mb sm. The throughput is separate by the uplink and downling parameter % with the software scheduling strategy OK !
But what is i use the hardware scheduling? The aggregate throughput is now 14 mbps and i have no possibility to control the allocation of trafic because this is now dynamic, base on amount of high priority traffic.

As long as i would like to have the image from my camera on the sm side can someone know what unlink speed we can expect ? Cause i need to have a constant 6mbps of uplink.

Thanks
