Wi-Fi Direct enabling P2P communications amongst WiFi wares, scaring Bluetooth half to death

by Darren Murph posted Oct 14th 2009 at 12:01AM

Hear that Bluetooth? That's the sound of competition... finally. After years of waiting for some sort of serious rival in the short-range communication realm, the Wi-Fi Alliance is doing what it should've done eons ago. Starting sometime in mid-2010 (if all goes to plan, of course), a Wi-Fi Direct specification will be published, enabling WiFi'd devices to connect to one another without some sort of WLAN hotspot nearby. Previously, the standard was codenamed Wi-Fi peer-to-peer, as it gives printers, mobile handsets, human interface devices, cameras, laptops and a host of other wireless wares the ability to talk to one another without first consulting an access point. We're told that devices will be able to make "one-to-one" connections or talk amongst a group, and WPA2 security will be bundled in to keep the ill-willed sniffers at bay. Call us crazy, but we get this feeling we're going to dig this protocol -- now, if only we could actually count on seeing shipping products before we're too old to enjoy it, we'd be set.

USB 3.0 logos now being handed out to certified wares

by Darren Murph posted Sep 1st 2009 at 2:56PM

Aww suki suki now. With CES 2010 leaning around the corner and refusing to leave our periphery, we're getting more and more evidence that the January trade show will be a launching pad for a new suite of USB products. Several months after the first USB 3.0 cables curiously went on sale, the USB Implementers Forum (USB-IF) has announced the availability of the USB 3.0 Compliance and Certification Program. What's that mean? It means that a program is now firmly in place to provide compatible wares with a SuperSpeed USB logo, which in turn means that USB 3.0 gear is that much closer to retail shelves. So, who's anxious to slap a USB 3.0 PCI expansion card into their shiny new PC?

802.11n finalization just a formality, interoperability to be preserved

by Darren Murph posted Jul 27th 2009 at 3:56AM

C'mon, say it with us: "phew!" Considering that just about everyone has been shipping "802.11n" wireless kit since draft 2.0 was put into play two summers ago, we couldn't be more relieved to see the Wi-Fi Alliance confirm that it won't change the baseline requirements of its 802.11n certification program when the format gets certified this September. Just as we'd heard, the WiFi standard will leave its stagnant draft status and sashay into the wondrous realm of officialdom in merely two months, with the updated test program to "preserve interoperability with more than 600 Wi-Fi certified 802.11n draft 2.0 products released since June 2007, while adding testing for some optional features now included in the standard." Good thing, too -- can you imagine the uproar if your forthcoming 802.11n dongle wouldn't play nice with that draft-N router you snagged last June?

802.11n should go final by September, just when it's starting to feel slow

by Darren Murph posted Jul 21st 2009 at 10:09PM

It's been a long, long... long time coming, folks. Since 2004, the world at large has been waiting for 802.11n to finally go legit, and while we've been getting along just fine with Draft-N devices, the IEEE is inching closer to completion of the final specification. According to Bob Heile, the chairman of the IEEE 802.15 working group on Personal Area Networks, "802.11 [has been] granted unconditional approval to forward 11n to RevCom," which is currently scheduled to take place on September 11th in New Jersey. He continued by uttering the understatement of the year with "this was an extremely complex project." We won't even bother retracing all the time line slips that we've seen over the years, but we can't help but chuckle at the notion of an ever faster 802.11 protocol to be discussed at the very same meeting. So, let's see here -- 802.11n finally gets its certificate of authenticity after parading around for half a decade as an unfinished draft, and CES 2010 brings about devices based on the even faster 802.11ac. Marvelous.

SATA Revision 3.0 specification completed and released

by Darren Murph posted May 27th 2009 at 1:22PM

Well, it sure took 'em long enough. In August of last year, the Serial ATA International Organization (SATA-IO) got us all hot and bothered when it introduced the SATA Revision 3.0 specification to double transfer speeds to 6Gbps. It's taken until today, however, for that very specification to be completed and released. Thankfully for those who love to relish in the past, the new spec is backward compatible with earlier SATA implementations, and for those looking forward to new innovations, you'll appreciate the new streaming commands for isochronous data transfers between audio and video applications and the Low Insertion Force (LIF) connector for more compact 1.8-inch storage devices. We're told to expect SATA Revision 3.0 demonstrations next month at Computex, but who knows how long it'll be before this stuff seeps into shipping products.

Standardized EV plug could be adopted within months, says GM

by Ross Miller posted Apr 21st 2009 at 9:38PM

Here's a more reassuring timeline for that proposed standardized plug for electric vehicles. The SAE J1772 Task Force-developed charging system, based on an initial design by supplier Yazaki, is now at Underwriters Labs for certification. That's scheduled to be done by the end of May and, if all things go according to plan, it can be adopted for use in the next few months. Speaking to Autoblog Green, General Motors' Gery Kissel listed his company, Chrysler, Ford, Toyota, Honda, Nissan and Tesla among those participating or supporting the standard. He also said the we-swear-it's-coming-this-year Chevy Volt should be equipped with the new plug, and Tesla's reportedly pledged to adopt it for current plans and retrofit its older models. Things are starting to look up for the EV industry.

Automakers agree on common plug to recharge electric vehicles

by Darren Murph posted Apr 19th 2009 at 4:24PM

Just hours after General Motors put forth a proposal for a standardized plug for electric vehicles, in flies this. German energy firm RWE has stated that a cadre of respected automakers and energy firms have all come together in agreement on a three-point, 400-volt plug that will enable electric cars the world over to be recharged anywhere, regardless of which recharging station they stop at. Caroline Reichert, an RWE spokeswoman, noted that the idea here is to ensure that "a car can be recharged in Italy in exactly the same way as in Denmark, Germany or France." We're told that the agreement includes nods of acceptance from the likes of Volkswagen, BMW, Ford, General Motors, Fiat, Toyota, Mitsubishi, Eon, Vattenfall, EDF, Npower, Endesa and Enel, and while there's no time frame for when it'll be introduced, we're pretty stoked to hear that at least something has been decided upon.

GM proposes standardized plug for electric vehicles

by Darren Murph posted Apr 17th 2009 at 8:11AM

Say what you will about General Motors (okay, so maybe you should say it under your breath), but there's no denying the brilliance of this idea. On the company's FastLane blog, one Gery Kissel explains that engineers and suits will be meeting up next week to discuss the standardization of common components that will hopefully be installed in forthcoming electric vehicles. Notably, the SAE J1772 Task Force will be responsible for designing a plug that links each plug-in vehicle to an "ecosystem," ensuring that drivers can pull into any charging station from Key West to Neah Bay and see a socket that fits their ride. Specifically, the group is being charged with defining a "common electric vehicle conductive charging system architecture for all major automakers in North America," but it remains to be seen if said standard can be hammered out before the Volt's not-to-be-missed 2010 introduction.

IEEE begins work on wireless standards for white spaces access

by Darren Murph posted Mar 24th 2009 at 10:55AM

We're probably still months, if not years out from seeing this whole white space debate amount to anything productive, but at least the IEEE is already toiling away on two new standards to address architecture and interfaces for white spaces access. In an admittedly jargon-filled release, the group responsible for keeping 802.11n in draft status for 14 centuries has reportedly approved work to begin on a new duo of protocols for "heterogeneous wireless networks based on the existing IEEE 1900.4 standard." The group specifically mentions IEEE P1900.4a, an amendment to 1900.4 which aims to "examine architecture and interfaces for dynamic spectrum access networks in white space frequency bands." Said standard would basically act to define new components for operating in white space frequencies, and with standardization will hopefully come easier implementation of widespread broadband. Check back in a score or so to see if we've made any progress.

Bluetooth SIG promises high-speed specification next summer, likely BT 3.0

by Darren Murph posted Dec 8th 2008 at 9:52PM

After putting those nasty Bluetooth 2.2 rumors to bed, the Bluetooth Special Interest Group has directly informed Wireless Week that it will indeed look to come out with a "high-speed specification next summer." Of course, we've been waiting on such a thing for, like, ever now, but Executive Director Mike Foley has asserted that when the spec arrives in summer 2009 it will likely be sitting at 3.0. What's 3.0 promising? Faster overall transmission speeds and quicker connections, namely. So, what's the over / under on the Bluetooth SIG actually delivering?

ATSC gives initial thumbs-up to MPH mobile TV standard

by Darren Murph posted Nov 27th 2008 at 6:59AM

Merely weeks after a handful of TV broadcasters voiced their approval of the MPH mobile TV standard, the almighty ATSC has elevated its specification for Mobile Digital Television to Candidate Standard status. Or it will early next week, based on the futuristic December 1st date on the press release. Anywho, the thumbs-up brings the standard one huge step closer to actual implementation in the United States, though a final standard isn't apt to be agreed upon until late next year. Not that the delay is really a problem -- after all, a grand total of 19 people in this great nation even care about TV on the go, right?

Panasonic puts forth proposal for 3D standard on Blu-ray Disc

by Darren Murph posted Nov 24th 2008 at 10:57PM

For those of you plugging your ears whilst humming along in hopes of this whole 3D revolution fading away, we've got a rude awakening headed your way. Just days after hearing that the HDMI specification could be updated to better handle stereoscopic 3D content, along comes word that Panasonic has submitted a proposal to the Blu-ray Disc Association (BDA) for an official BD standard to store 3D imagery formed of "left / right-eye two-channel Full HD images." Panny reportedly made the move early in order avoid a format war, but really, it's just looking to cash in on royalties for the next ~~decade~~ five years or less. It's no secret that movie studios are dead set on moving forward with 3D production -- might as well be ready on the other end, right?

USB 3.0 specification to be formally unveiled this month

by Darren Murph posted Nov 6th 2008 at 9:56AM

We've already got the controller specs, now we just need the full-on protocol specs. Speaking at the Windows Hardware Engineering Conference in Los Angeles, USB-IF president Jeff Ravencraft reportedly stated that he expects the "final specifications to be made public on November 17," and given that said day will mark the opening of the SuperSpeed USB Developers Conference in San Jose, we'd say it all jibes pretty well. Now, how many months will we have to wait before manufacturers can actually get the hasty new ports into machines?

USB 3.0 gets seriously detailed

by Darren Murph posted Aug 18th 2008 at 3:36PM

Just last week, Intel gave AMD, NVIDIA and a whole host of friends what they had been clamoring for: 90% complete USB 3.0 controller specifications. Now, the cool cats over at MaximumPC have churned out an encyclopedic writeup that details USB SuperSpeed remarkably well. The highlights include assurance that USB 3.0 will be backwards-compatible with USB 2.0 and that it'll provide transfer rates up to ten times more than USB 2.0's 480Mbps limit (that's 4.8Gbps). Furthermore, we're told that uploads and downloads are kept on separate lanes, the cables are thicker, it will charge more devices more quickly, and it will be much more mindful of energy waste. Go on and get yourself completely schooled in the read link below.

RF4CE Consortium aims to develop RF standard for entertainment control

by Darren Murph posted Jun 13th 2008 at 7:40AM

Whittling down the amount of remotes in one's living room has long since been a challenge for the amateur home theater builder, and while there are some decent universal solutions on the market, the RF4CE Consortium is hoping to make things painfully simple. The group has been formed in order to "drive the adoption of an open radio frequency (RF) entertainment control specification based on IEEE 802.15.4." If you'll recall, this isn't the first time we've heard that standard called, as it's also used in MaxStream's XBee Xtender. Notably, Freescale is hoping to incorporate its Synkro technology into the specification, and in an ideal world, we'd see said protocol filter into DVD players, AV receivers, set-top-boxes and all manners of components. Let the IR-to-RF transition begin, we say.
