In fact, there isn't much point at taking it out of the box yet, should you be dumb enough to buy.
beamforming might help, out where I live, with limited neighbors, but once you get a few dozen of these in an apt complex no one will see full speed for long as the available channels become totally saturated.
First off, while it's very expensive to get the benefit from 802.11ac right now. Aside from price, there's nothing stopping anyone from buying another router to use as a bridge, or a bridge. (Buffalo sells one already)
And i think you have no idea how beam-forming works. The signal itself doesn't propagate as a "beam" all of a sudden because of it. So interference wouldn't really go away.
However, you are still wrong about the apt. complex example. Not because of beam-forming, but because of the 5ghz spectrum. there's a lot more channels available for 802.11ac that don't overlap.
Something not possible with wireless N at 2.4 ghz because there's basically only 2 channels to choose from to get full speed (40mhz channels), and only two of those channels don't overlap.
Or more realistically, 3 channels since the scenarios to run 40mhz width on 2.4 are almost non-existent.
So you get 3 channels to choose from, of course this is going to cause huge interference issues. (1, 6 and 11 for those wondering)
But with ac there's a lot more bandwidth available, so there's also more channels to choose from.
So, if you are living in an apt complex it wouldn't be too hard to setup your WiFi on non overlapping channels, you'd have to sacrifice some raw speed, but at least there won't be interference.
you can get either:
9 channels to choose from that don't overlap @20Mhz, 4@40Mhz, 2 @80Mhz or even 1@160Mhz
As you can imagine, while this won't completely solve interference problems. But crowded places will fare a LOT better than they did before.
Yes I understand the idea of bridging.
The section I struck was a quote from the story.
My point was time after time with each standard companies began releasing "draft" products to end users GUARANTEEING that they would work fine or be upgradeable to the final standard, and few were totally compatible, quite a few never performed as advertised, missed out on important features, and most of the GUARANTEES were worthless. worse some of the early Draft models turned of to be the source of interference/channel pollution, but could not be withdrawn from the market.
Those that worked "pretty well" even with some limitations were fine for use as el cheapo routers/APs (in fact lots of draft 'n' are available on "last chance" electronics sites for under $15 right now)
But non really met the "fully compliant, 100% upgradable, all bells and whisles hype, and the same will MOST LIKELY be true of draft A/C units.
No great hurry IMHO
