Sigma Designs has been dabbling in wireless HD technologies for eons, so we aren't going to get too excited until we see this here system-on-chip (SoC) actually hit some products that we care about. Still, the CoAir is a fairly sweet concept, wrapping integrated wireless, coax and gigabit Ethernet capabilities into one single chip aimed at whole home networking. Put simply (or as simply as possible), this chip is the world's first to "simultaneously deliver multiple independent streams of video and data over coax cable, Ethernet cable and wirelessly without compromising quality of service and throughput." Based on the WiMedia standard, it can reach speeds of up to 480Mbps with UWB (ultra-wideband) wireless streaming, and room-to-room linkage via UWB-over-coax can peg those same rates. What we have here is a great basis for building a whole home server on, but until said device emerges and performs flawlessly, we'll just smile and carry on.

A lot of things in the high-def world are going down in 2012, so it's not shocking at all to hear that we've got yet another thing to look forward to during that fateful year. ABI Research has just loosed a new report that tags wireless HD as being in its "incubation" stage, with fewer than 100,000 devices in the sector scheduled to ship in 2008. Furthermore, analysts are suggesting that 2012 would be the earliest point in which one million wireless HDTV installations occurred worldwide -- and that's an "optimistic forecast." We posed the question a few months back wondering just how long it would take for this stuff to take off. 'Spose we have our answer, huh?

Believe it or not, Aztech's WL850MS was actually first mentioned way back at CES 2008, but it's just now finding the limelight at CommunicAsia. The well-spec'd unit supports 1080p media streaming over Ethernet or 802.11n WiFi, and you'll likely be thrilled to know that it boasts MIMO antennas for extended coverage and 2.4GHz / 5GHz dual-band capability. You'll also find four 10/100 Ethernet ports for multiple video recipients and a pretty swank enclosure, if we may say so ourselves. Word from Singapore has the unit retailing for around $263, but there's no telling how long we'll have to wait before seeing it on US soil.

There's not much explaining to do once the name of this product is read aloud, but we'll humor you anyway. The recently announced VUDU Wireless Kit is something we dreamed of having when testing the thing out in our own labs, but we suppose late is better than never. The package contains a pair of 802.11g adapters -- one for your VUDU set-top-box and one for your WLAN router -- that creates a "secure, self-contained wireless network" for transferring material from VUDU's servers to your device. The going rate for this bundle is $79, but you can knock $29 from that if you purchase it directly from VUDU with a $299 STB. Now, the real question here is this: will this thing function reliably (wireless HD has been shoved under the rug for a reason, you know), and will it function reliably with HD content. Any guinea pigs out there willing to check?

Funny -- just this week we heard Hitachi President Kazuo Furukawa make mention of a forthcoming Wooonet networking scheme for its Wooo HDTVs, and now we're getting a few more details on potentially related peripherals. Analog Devices has just announced that its Advantiv technology is playing a huge role in the TP-WL700H. Said device is an ultra-wideband (UWB) based wireless transmission hub, which is currently available exclusively in Japan and designed to bring high-definition material to Wooo HDTVs sans extra cabling. There's not a peep about the unit ever heading Stateside, but given that everyone and their second cousin once removed is wondering when wireless HD will ever take off here, we'd sure like to see it make the journey.

Monster Cable -- the firm famous for grossly overcharging for its wares and suing nearly every company on Earth with "monster" in its title -- is going wireless. Yep, rather than gouging customers for Unicorn-like wiring, it'll now be promising to transmit signals through the purest air -- the kind only a Monster box could attract, most likely. Over at Hometech 2008 in Dubai, CEO Noel Lee affirmed that it would soon be "coming out with wireless," also noting that the elusive product(s) would be based on ultra-wideband (UWB) technology and support 1080p. Beyond that, it looks like we'll be waiting for specifics, as an official announcement of the device won't come until the "second week of June." Lee also stated that it "[wouldn't] be inexpensive," and threw out a $600 estimation for "a pair of boxes," while each additional room would cost $200 to connect. Color us absolutely unimpressed.

Remember those "world's thinnest" X-Series LCD HDTVs we spotted earlier this year? On their way over from Japan to the US, Sharp has whipped up a partnership with AMIMON in order to offer a wireless HDTV link based on the latter company's WHDI technology. Apparently the 37-, 42- and 46-inch displays will be sold in both nations with an optional wireless video transmitter (read: each set is "wireless ready"), giving users the ability to send uncompressed HD to their HDTV from up to 100-feet away. As for US pricing and availability, Sharp's not quite ready to dish out those points, and while we're not exactly sure if this is the launch that finally gets wireless HD headed in right direction, it certainly can't hurt matters. Full release posted after the jump.

This week's Ask Engadget HD question is near and dear to our hearts, and quite frankly, it's one of the best inquiries we've heard thus far. After a veritable onslaught of wireless HD, wireless HDMI, WHDI and other cord-free HD apparatuses were introduced and trumpeted at CES 2008, the hubbub has completely died in the months after. Sure, we realize many firms were simply showing off unreleased kit back in January, but it seems the push for untangling one's components has been (at least momentarily) halted. Check out Jeff's concerns for yourself:

"When is wireless HD finally going to hit the market? Philips introduced a wireless HDMI product that never saw the light of day; now Belkin (FlyWire) and Gefen have announced similar examples at CES, but there's no word on when either will hit the market. Yes, this technology comes with a large price tag, but when will those willing to pay for a clutter-free setup have the chance to?"

Beyond all that, we're wondering if these kinds of products will even impress once unleashed. In our experiences, transmitting loads of data over any form of wireless setup has been prone to dropouts, hiccups and all sorts of annoyances. Heck, even PowerLine has yet to overcome the stigma attached to it -- and it's a wired technology! Personally, we're hoping companies with wireless HD wares are taking the time to perfect them rather than handing them over unpolished, but still, will you be willing to subject yourself to possible early adopter woes when this stuff finally greets retail floors en masse?

Got a burning question that you'd love to toss out for Engadget HD (or its readers) to take a look at? Tired of Google's blank stares when you ask for real-world experiences? Hit us up at ask at engadgethd dawt com and keep an eye on this space -- your inquiry could be next.

It's been a tick since we've heard a noticeable peep from Avocent, but the firm has recently unveiled the true successor to its Emerge MPX1000. The aptly-named MPX1500 is still a high-definition multipoint extender at its core, but rather than relying on swappable output modules, this unit packs a single DVI-D output and uses adapters to output HDMI, component, S-Video, VGA and composite. Additionally, this newer iteration comes in a much smaller enclosure and offers VGA resolutions up to 1,360 x 768 (while HDMI / DVI still goes to 1080i). Reportedly, users can still expect to see signals transmitted sans wires up to 150 feet through walls, and if interested, can pick one up as we speak for $995.

We knew Hitachi's Ultra Thin HDTV family would boast ultra-wideband technology, and while little was said about this aspect during CES, we've now learned that Tzero will be responsible for handling the aforementioned UWB duties. As expected, the UT HDTVs will "be able to receive high-definition video wirelessly from any HDMI equipped audio / video component," as Tzero promises that users will see transmission speeds of up to 480Mbps. Interestingly, we're told that the UWB-equipped sets are available in Japan right now, but only time will tell if those luscious wireless abilities will make the trip stateside in Q2.

Truth be told, we were pretty intrigued by the sheer quantity of features and the very respectable price tag affixed to the EZfetch Wireless HD Digital Media Player, but according to a review over at Networking Audio / Video, there's a lot left to be desired. Of course, the device seemed to have no qualms playing back video over a wired connection, but the lackluster audio streamer and underwhelming photo viewer started putting a real damper on the party. Worst of all, reviewers never could get the unit to function as advertised over a wireless network, which we assume would be a huge selling point for many. Granted, we suppose another unit in another setting may set up just fine, but we'd recommend giving the review below a once over and doing a bit more digging for user experiences before pulling the trigger on this one.

After waxing rhapsodic in our last podcast about how dodgy the issue of wireless HDMI / wireless HD really is, we're beginning to wonder if passing along 1080i / 1080p content on existing power lines is an acceptable (or flat out better) alternative. Granted, PowerLine applications haven't had the best of luck over the years functioning as advertised, but given that PowerLine-enabled HD media streamers are already seeing reality, we're hoping the technology can advance beyond its flawed past. Another example of said technology moving forward is the debut of several PLC (Power Line Communication) adapters from Sharp, which can be used to connect an AQUOS Net HDTV (among other devices) to the internet via electrical wiring. Truth be told, we're crossing our fingers that this stuff can really take off -- after all, you'll still be stuck figuring out a way to run a single wire to an AC outlet regardless of everything else. Of course, only time will tell if DRM-laced, uncompressed HD content will flow unimpeded through a home's electrical infrastructure, but this corner is definitely rooting for it.

We already knew Panasonic was linked in with WirelessHD, but the outfit is choosing CES to come out in the open and trumpet its development of a transmission system. Apparently, it partnered up with SiBEAM to dish out a system that will enable "HD video transmission in uncompressed format," and while Panny gloats quite heavily about the use of a 60GHz band, it's really not all that surprising. 'Course, it seems we've got awhile before this stuff hits en masse (in actual products), but at least we've got yet another corporation on board, right?

Toshiba's presence at CES isn't limited to just LCDs due in the first half of the year, we've also got a look at a few products with no definite release date. First up are Cell B.E.-equipped Qosmio (Cell-less current model pictured) and standalone HDTV prototypes designed for video upconversion, with the usual gamut of realtime video transcoding demonstrations. Also on tap is the next generation of Regza Link based on WirelessHD and a Direct Methanol Fuel Cell for mobiles.

Amped up about the onset of CES? Stoked about the possibilities of wireless HD? If you answered yes to even one of the aforementioned questions, here's a tidbit sure to keep you salivating. Apparently, a not-yet-named "leading consumer electronics manufacturer" will be showcasing a WHDI-enabled HDTV at CES, which will reportedly be able to receive "uncompressed 1080p 60Hz HD video streams wirelessly." The chipset handling the dirty work is the AMIMON AMN2110/AMN2210, and while there's little more to say beyond that, you can rest assured that we'll be looking to find out more about this elusive set as soon as it gets unveiled.
