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. MP Divakar

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?

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.

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! MP Divakar

Correction: ...it is NOT efficient to stream content from Internet to SmartTV from the handheld!

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!

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?
