This 5 GHz comment makes me think that perhaps it's not widely known that the 5 GHz band was always part of the 802.11 protocol. The original 802.11a operated at 54 Mb/s on the 5 GHz band. Then came 802.11b and 802.11g in the 2.4 GHz band. But I'm using 802.11n in the 5 GHz band now. So it's not something new with the 802.11ac standard. Also: The main techniques used by 802.11ac, to increase the bit rate beyond 802.11n, are increase the constellation from 64-QAM to 256-QAM, which means more power needed to achieve the same range, and to widen the channel width from 20 or 40 MHz to 80 or 160 MHz. Which means, the crowding you now see in the WiFi 2.4 GHz band will occur in the WiFi 5 GHz band.

Totally agreed. Media distribution within home will benefit from 801.11ac running on less crowded 5 Ghz. By in the end, we are charged too much by our service providers in the US!

"At normal viewing distances... you won't be able to see the difference." There's a simple solution to that: move the couch closer to the television! My kids always want to sit in the back of a movie theater. I tell them that by doing that we paid $12 to watch it on a big screen. If you sit in the back you might as well be watching the movie on a cell phone. I like to sit up front. And when you do you can easily see the pixels in the 4k digital movies (it is kind of disappointing really--we need 8K!). I like full immersion, but we are decades from that, so sitting up close is the best you can get for now. (Okay, just maybe the fact that I'm a little near sighted might have something to do with wanting to sit up front).

Which link has the bigger impact depends on the usage model & behavior of the people in your household. If you've got a large archive of content on a DVR or media server, with multiple people accessing it wirelessly, then upgrading from 802.11n to 802.11ac could be a big improvement at your house. If on the other hand you've got multiple people streaming content from the cloud, the WAN connection might be the bigger bottleneck. It's frustrating that in the U.S., the broadband service model is that we pay a lot for a little, compared to some other countries that pay far less for huge (100Mbps) pipes.

Frank, why you say that? At normal viewing distances, unless you have a extremely large TV, you won't be able to see the difference. It'll be years before there's any 4K content. Already cable companies are overcompressing HD channels to crowd in ever larger numbers of channels, does anyone doubt the same fate would eventually befall 4K? I think 4K will probably be successful in the same way 3D was, from a sales standpoint only. It'll eventually be bundled with every higher set like 3D, so it'll achieve great market penetration. But like 3D, only a small number of buyers will make regular use of the 4K capability. The one thing I do look forward is from 4K is that when it becomes mainstream then monitors with 4K resolution will become mainstream as well. That's somewhere there's an obvious benefit, because I sit maybe 20" away from my 27" monitor, versus 10' from my 50" plasma.

UHDTV will become mainstream even more quickly than HDTV became mainstream.

A couple of comments. First, it is not 802.11ac that will make the biggest impact. With 802.11n, I already get 270 Mb/s in the house. The weak link in the chain is clearly the broadband connection TO the home, and perhaps DOCSIS 3.0 can solve that problem for those who have cable. If you rely on xDSL, I can see a path to 50+ Mb/s, but not anything close to 1 Gb/s. So, I think the emphasis in the article is on the wrong part of the distribution chain. It's the last mile connection that should have been discussed, not the in-home network so much. As to smart TVs, I agree that it's more than just the software that would require upgrades. But (a) hardware upgrades are required much less frequntly, and (b) clever design could easily take care of that too. How hard can it be to provide a cell phone sized replaceable module with the smart TV set? Honestly, I continue to be utterly baffled by the unimaginative discussions surrounding smart TV. With all the clever devices available out there, when it comes to TV, it seems like everyone hits a brick wall.

Please see the SONY TV on Ultra HD. Unfotunatly the price is high (need to come down by min 6x to be affortable). As always, cost will come down. It is a beauty. With faster FPS and fill rates. You feel like you are in Swiss.

WiFi everywhere makes sense...but needs to migrate to 5 GHz band, otherwise 2.4 GHz will be too congested (it might be already)...I don't see UHDTV happening, what for? so I can see Swiss alps more clearly?
