I think that’s a fair assessment of the technology from last year….most AC implementations never thought they’d achieve MCS 9 regularly with a generation ago RFIC technologies and required RX sensitivities.
Now that RFIC implementations have evolved to try to actually improve this, we’re seeing it is far more attainable to hit MCS 8/9 quite regularly, especially in narrower channels. But MU-MIMO and beamforming alone are big improvements even if you can’t get past MCS 7. Beamforming delivers 3 dB extra “processed” gain on it’s own.

If the only way to gain more throughput in AC (over N) is to increase the channel size, then there is no significant gain in AC. bp <part15sbs{at}gmail{dot}com> On 3/13/2015 1:42 PM, Vince West wrote: To an extent. More range, more speed, beamforming. But are you really gaining anything in the smaller channel sizes with AC in 2.4Ghz? I don't know the standard really well aside from it's obvious gains. The main things, AFAIK, that are beneficial from AC are the increased speeds and beamforming. I understand where beamforming is important. And better range. It would be interesting to know what can be gained from 802.11ac in 2.4Ghz but the main argument I have heard against it is that there isn't enough spectrum.
