Here is what QCA had to say:
Hmmm interesting. I wonder if that means either the radios in this router are not actually QCA, or that there is something else going on resulting in the pronounced difference in RSSI between the two clients and only for this basestation.
I also wonder if they mean with 2.4GHz, or in general. Or just with their development. Others seem to at least be boasting for fairly large gains being possible (IIRC Quantenna say "10 decibles" with their EBF implementations for, I assume TxBF).
Again, this could be something totally different going on, but I'd consider my WDR3600 to be a very decent performer, and this 11ac AC1750 router blows it out of the water on 2.4GHz 40MHz with the same client (Intel 7260ac). I see from 15-60% higher Tx and Rx performance with it depending on location (generally with medium distance having the largest gains). Same example as above, at my kitchen table with 40ft, a floor and a couple of walls, plus it being VERY oblique through them I see around 4.5-5MB/sec with 2.4GHz 40MHz with my WDR3600, with the AC1750 its rocking north of 8MB/sec (a 60+% gain).
At long distance with another 15+ft and a 4ft masonry fireplace in the way, the WDR3600 was managing 2-2.5MB/sec, the AC1750 a pretty constant 3.5MB/sec (yeah, both are slow, but 3.5MB/sec is still a lot more usable). Very close in the WDR3600 was rocking 24MB/sec, the AC1750 is hitting 28MB/sec and even a little north (I think the highest peak I've seen has been 28.7MB/sec. The average transfer speed over 3 test transfers of a 900MB file were 27.6MB/sec), about a 16-17% difference.
I'll deffinitely grant something else could be going on (and it can't be character set encoding differences, they are both only doing 64QAM/150Mbps per 40MHz stream, not 256QAM/200Mbps per 40MHz stream for the AC1750).
