3x3 and beam forming would come in handy on 2.4, both of which are available with 802.11n specs, just rare as hen’s teeth in practice.
You’d think someone could convince Atheros to build the chip. From: Jaime Fink Sent: Friday, March 13, 2015 4:32 PM To: [email protected] ; Bill Prince Subject: Re: [AFMUG] AC spec available in 2.4? Chips that are 2 stage without integrated RFIC I think you will see will work just fine with no cost hit at all. You’re right though, most high volume chips are highly integrated chips with PA and RFIC, and clearly not focused on moving into this space (read: chips for mobile phones and low cost home router Wi-Fi chips). One of the reasons we love Quantenna…clean division of baseband chip and external customizable RFIC/PA, etc. Cheers, Jaime Fink • Mimosa • CPO & Co-Founder This email may contain confidential and privileged material for the sole use of the intended recipient(s).

Beam forming was an optional part of 802.11n. There are two types of beamforming, antenna based and chip/tx based. 802.11AC is significantly more efficient than 802.11N when it comes to protocol overhead, however the majority of the speed gain is from higher order modulations coupled with larger channel sizes. BTW, 160MHz wide channels are on the horizon for 802.11AC rev3. MU-MIMO is nice. I would not expect to ever see a 2.4GHz "AC" chipset on the mass market at "reasonable pricing", even for ISPs. Too little to gain, on various fronts.

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.
