UltraGig: Proprietary blunder or 60GHz future?

Wi-Fi: Mega-highway inside the home
There is no denying that Wi-Fi continues to be the mega-highway inside the home. More than 1.5 billion Wi-Fi devices were sold in 2012 alone, according to ABI Research.
But that, in turn, could give rise to some legitimate concerns over congestion and robustness with WiFi devices in the future. Silicon Image is betting the farm (and its UltraGig) on that side of the argument.
Beyond the congestion issues, Vehling offered UltraGig’s low latency and better video quality as advantages. “60GHz Wireless HD offers less than 5ms of latency,” said Vehling, stressing its importance for gaming applications. Further, “due to increased bandwidth offered by 60GHz, video quality is better,” he added. “H.264 compression is not used.”
So what’s the bottom line?
This, of course, is the classic argument over proprietary technology vs. standardized spec. Undoubtedly, UltraGig’s drawback is that “it is a proprietary silicon solution, and Silicon Image is the sole-source silicon vendor,” said IHS analyst O’Rourke. “This makes it relatively expensive and a risk for CE vendors to offer it.”
Silicon Image has been marketing UltraGig to OEMs for a while, “without much success to date,” according to O’Rourke. Silicon Image is “caught in a dilemma – they need increased volumes to drive down chip ASPs, but OEMs want lower ASPs before committing to large-scale integration,” he explained.
“Another silicon source for UltraGig would help, as it would reduce the supply risk to PC or CE OEMs of offering UltraGig,” he added.
The battle between UltraGig and Miracast could also take a new, unexpected turn, however.

This article seems a bit confused. Miracast is basically a standardized version of AirPlay, built on WiFi Direct. It is used in Wii U, and is certainly here to stay.
60ghz technologies have been cooking for years, and are now reaching mass market. It has very high bandwidth but very short range--basically in-room. Like 2.4/5ghz, it is unlicensed.
There are two questions here: how valuable are the high bandwidth, short range use cases for 60ghz; and whether anything other than WiGig will survive, given general industry support.

My first comment is, it would be nice to know more about how Miracast works. The one comment that we should wonder about congestion, when Miracast and WiFi are attempting to coexist, is very valid. Miracast is not WiFi, but if it uses the same frequency bands as WiFi for uncompressed video, one should ask.
The second comment being, if you can get that streaming media content to your tablet or smartphone, why not think in terms of streaming it directly to the smart TV? Without this peer-peer link?
Why assume you need a tablet, a Miracast or UltraGig reception box at the TV set, and the TV set, to do what a smart TV should be able to do all by itself? Who or what is keeping smart TVs from giving the user the same UI as any tablet or PC out there? Anyone?

Think of 60GHz as a replacement for an HDMI cable used to link a web-enabled device - or just a set-top-box - with a display device. (No reason why the display screen should have its own personal web-access)

@plk & @Bert22306: I agree with your points. I don't know why one needs a hand-held (to stream media) that is largely redundant, wasting materials and resources. On the other hand, if we are talking about a hand-held that can double as a remote and meeting the plethora of confusing standards (RF4CE, 6LoWPAN, etc.), there is a play for it.
I am still holding out for a TV that can be gesture-controlled.

Simple. Your Smart TV is across the room. Your tablet or Smart Phone is in your lap. Mirroring the video strikes me as an inefficient way to do this, but having a console app in your tablet routing whatever you want to your TV makes all kinds of sense.

I think something got lost in translation in this debate. Yes, if you can stream all that Internet content directly to your smart TV, that's all the better and efficient. But the reality is that many consumers today already have a smartphone and/or a tablet. Sitting in a living room with your kids, chances are, some of them are surfing the Net on a tablet or smartphone already, while you are watching a big screen TV.
Wouldn't it be nice, if a relevant (or irrelevant) content found on a smartphone can be beamed onto a big screen TV during a commercial break, and share the laugh?
I am talking about the reality of multi-screen era in a living room. It's already here. If so, how best to connect those multiple screens?

Junko, it is NOT efficient to stream content from Internet to SmartTV! I can do that simply by transmitting the hyperlink (a couple of Kbytes at the most!) to the SmartTV from my tablet (if one doesn't want to use the TV remote to do that). I can do that today with my smart phone and WiFi.
What makes sense is to stream stored content from a handheld. But any day that works better in a wired manner like plugging in a USB storage device to your TV!
In the end, it is the consumer adoption that will prove or kill UltraGig. Time will tell.
I just don't like too much Emag smog in my living room!

What if you don't have a smart TV? I think you can get a Miracast to HDMI adapter, then you can control any television with your tablet.
Instant Smart TV, with a touchscreen remote!

Think of it this way, then. Instead of spending money on a Miracast to HDMI conversion box, and the Miracast transmitter at the tablet, make yourself a smart TV. Connect a PC to the TV, via HDMI, and control the PC with a wireless mouse (and wireless keyboard, when and if necessary).
Now you have a really smart TV that can stand on its own, and the tablet can be used for anything else.
This is reality too. It happens to be my reality. I went this route when I saw that the CE companies didn't know how to design a smart TV. So I gave up on them and did the obvious. Without waiting for Miracast or anything else.

Is is not simpler to have a low-bandwidth remote mouse next to you, to remotely control a smart TV, than to have to use a tablet that costs about as much as the set itself?
If you already have a tablet, great. Use it while watching TV, if you like, for something more useful than as a duplicate screen? It just seems silly to create such an expensive and bandwidth-hungry remote control for a TV, is all.
Perhaps the question proponents of this idea should ask, is the uncompressed video link electronics required at the TV and at the tablet going to cost LESS than a low cost thin client built into smart TVs? Maybe using Atom or ARM processors?
EVEN IF there will be times when you want to put those photos from your smart phone on the TV set, does that mean that all of your Internet TV watching must tie up a tablet too? I watch Internet TV all the time, on my TV, and have yet to need a tablet to do so.

I am all for increased bandwidth, lower frame rate loss, improved resolutions, etc.... but I am not finding either UltraGig or Miracast very exciting. Perhaps it is because I do not own a smart phone and have limited interest in watching TV? I see the 60Ghz frequency as being too short range for really being useful in the home (say floor to floor or end to end of the house). The cost adder for all the devices that the user would want to have supported also is a draw back, how many manufacturers would willingly add $10 or $15 to their product on a maybe future usefulness?

I think the future looks bleak for Silicon Image's UltraGig aka WirelessHD given the WiFi Alliance has embraced the WiGig Alliance's 60 GHz technology as its own and part of its road map.
So WiFi will have 60 GHz too and it will be an industry standard unlike UltraGig/Wireless HD which did not get backing from the folks it aimed to disrupt. The empire fought back--and won it seems.

To the consumer, it makes little difference which of the 60 GHz schemes "wins." To the consumer, this will in essence be a wireless HDMI link, of limited range and limited wall-penetrating acumen, but way more bandwidth than you could hope for in the 2.4 or 5 GHz bands. So it's all good stuff.
I see that it is called 802.11ad, and that products combining 802.11ad and 802.11n are already being demoed. This is good. It would allow standard house coverage of WiFi, plus this "wireless HDMI" link within a room, for example.
The interesting historical aspect of this is that the 60 GHz band started being considered when it became obvious that the ultrawideband (UWB) radio hype wasn't panning out. Remember that hype a few years ago? It fills that same functional role, though. Short range, say 10 meters or so, very high bandiwdth wireless.
