Two years after assembling a team to fight the tyranny of wires with 60GHz beaming and less than a year after entering mass production, SiBEAM has unveiled its second generation of WirelessHD chips, this time with the promise of low cost, mass adoption price points with an eye towards reducing overall costs and improving video quality. The new 65nm chips don't require active cooling, use less power and take up less space, plus integrate HDMI, HDCP and DTCP support and surround sound capability. Last year the premium was too steep for us to consider wireless HDTV as a serious option, but as costs come down and manufacturer support comes up it may be time to take another look at WirelessHD.

Panasonic has cleared a path for its WirelessHD equipped HDTV to launch in the UK now that Ofcom has opened up the necessary radio spectrum for use by all manufacturers. As it stood, manufacturers needed to get permission to use any part of the wireless spectrum, but now anyone should be able to use the 57-66GHz range. Expect the 54-inch version of Panasonic's wireless set to run around £5,000 when it becomes available in a few weeks, with other wireless TVs from LG and other coming later in the year.

The biggest question about all that wirelessly connected AV equipment coming our way in the near future (other than how much extra will it cost) is how well it will all work together and under what conditions. Agilent says its CTS-1000 automated test system is up to the task of sorting things out for WirelessHD hardware, measuring frequency, power, bandwidth error rate and other stats to make sure equipment makes the 60 GHz grade before its stamped with the WiHD logo. Pictured above is just one piece of the system, the Infinium 90000A Series Oscilloscope, a better look at things can be had for an easy $350,000 - $500,000, depending on setup, available now for early implementers (we assume Panasonic has one) and June 1 for everyone else.

With its 2009 LED-backlit LH90 LCDs already announced, LG has decided its LH80 line should be next up, its first of many -- following Panasonic's lead -- packing a Wireless HD media box to stream any HDMI, USB, or OTA content to the TV. Available in Korea is just this 55-inch model for about 5.1 million South Korean won ($4,008) but you can check out our CES '09 Wireless HD demo for a better look at the box and display while we wait for its LH85 branded U.S. cousin to make an appearance later on this year.

Finally, something wireless high definition related that's not delayed. As promised, Panasonic's Z1 line of Wireless HD packing 1080p plasmas and assorted accessories went on sale this week for the discerning yen spending consumer. It'll be June before these make a U.S. debut, pop on over to Panasonic's Japan site and pore over some machine translated spec sheets in the meantime.

Now that it's official and priced, Panasonic seems much happier to show off its wireless HD-sporting, ultra-thin Z1 series, and it's quite the sight to behold. The 54Z1 we got to look at was very strikingly clad in brushed metal gray -- compared to the regular black of most of Panasonic's TV lineup -- and of course incredibly thin. The wireless HD receiver box was across the room and working flawlessly, and it was nice to see that the included remote is an RF unit, capable of non-line-of-sight channel changing -- it's starting to feel like the 21st century around here! The plasma picture was of course very good, and we're really feeling those Viera Tools icons across the bottom. $6,000 though? That's your call.

If a Panasonic prototype plasma and new copy protection spec weren't convincing enough, we'll let the Wireless HD group argue why it's ready to compete with WHDI and all the rest. This summer's big get is Broadcom, ready to promote Wireless HD as a necessary feature in the army of HDTVs and set-top boxes it already powers. The next step to exiting vaporware status? How about the addition of Denon, Onkyo, Pioneer, Sharp and others ready to adopt the technology. Punch the read link for more reasons to believe, but we'll wait for shipping hardware to decide who makes it past first cut.

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.

WirelessHD (WiHD) is back, originally announced in late 2006, the 1.0 spec has been pronounced fit for consumption and will be released later this year. What's changed in the last 14 months? HD dream team Intel, LG, Matsushita (Panasonic), NEC, Samsung, SiBEAM, Sony and Toshiba have added 40 other companies as well as approval from DRM watchdogs MPAA and DTLA for their 60Ghz-based standard. Move over cable vs. satellite, downloads vs. disc and HD DVD vs. Blu-ray, with UWB-equipped HDTVs already on the way, a battle to replace the still-tricky HDMI connection is the new HD battleground for 2008.

Six of the world's largest consumer electronics companies have joined with startup SiBEAM to form the WirelessHD interest group. They expect to complete the WiHD spec by spring of next year, using the unlicensed 60GHz frequency to stream digital information at multi-gigabit rates. The advantages of using SiBEAM's solution is that such chips can use higher power levels without overlapping other frequencies, yet are limited to a short range and won't penetrate walls. With the backing of LG, Matsushita (Panasonic), NEC, Sony and Toshiba, this standard could easily overtake WiFi- and UWB-based solutions others are working on. Its backers expect HDTVs, DVD players, receivers and other devices based on the technology to start rolling out in 2008, leaving us wondering: why can Sony and Toshiba cooperate on this high definition standard, but couldn't make Blu-ray and HD DVD work together?
