Why didn't they firm this up sooner?
Our mobile devices, from larger ones like laptops to smaller ones like cell phones, have a good number of wireless radios inside of them.
Having a Wi-Fi radio is essential to connect to access points for internet connectivity, which is how most people use their Wi-Fi hardware. Of course, Wi-Fi radios can also connect laptops together for ad-hoc networks.
So why, then, do we not use our Wi-Fi radios for connecting more devices together, such as cell phones to laptops, or even cameras, printers--some of which already have Wi-Fi hardware? The Wi-Fi Alliance has pondered the same thing and today announced that it is nearing completion of a new specification enabling Wi-Fi devices to connect to one another without joining a traditional home, office, or hotspot network.
The Wi-Fi Alliance said that it expects to begin certification for this new specification in mid-2010, and products which achieve the certification will be designated Wi-Fi Direct (formerly code-named "Wi-Fi peer-to-peer").
The upcoming spec would allow all sorts of devices to interface with each other, including keyboards and headphones. This, of course, would threaten Bluetooth as the close-range wireless standard for small devices.
Perhaps most excitingly is that devices certified to the upcoming new specification will also be able to create connections with hundreds of millions of Wi-Fi legacy devices already in use. It's unclear if legacy hardware will require software updates to support the Wi-Fi Direct standard, but we'd imagine so.
"Wi-Fi Direct represents a leap forward for our industry. Wi-Fi users worldwide will benefit from a single-technology solution to transfer content and share applications quickly and easily among devices, even when a Wi-Fi access point isn't available," said Wi-Fi Alliance executive director Edgar Figueroa. "The impact is that Wi-Fi will become even more pervasive and useful for consumers and across the enterprise."
Wi-Fi Direct will feature many of the same features and characteristics of existing Wi-Fi, such as WPA2 security, ranges and data rates.

Microsoft's Origami UMPC: What were they thinking?
Indianapolis (IN) - "What am I?" asked the little translucent caption, as it floated innocently above the landscape, the mountainside, the beach, and the park, merrily rejoicing in its possibility-filled anonymity. Play a game with me, fill in the blanks, conjure me into what you want me to be. Okay, we reasoned with ourselves, we know it's really going to be Windows - it is, after all, Microsoft asking the question - but what is this thing, really, we asked? Could this be the framework for a fun and useful device that will tell us where we are, keep in touch with the office and our family, gather the news from all over the world, and play the music we want wherever we happen to be? This could be something. This "something," as various somethings from Microsoft turn out to be, is another way to cut, slice, and dice Windows into a smaller form factor. Okay, we thought, so this could be a nice platform for running Office applications while you're on the go. Well, no, not really - you could run Office on this little device, but without a keyboard and with an interlaced screen, that's going to be a challenge. Okay, then, so it's a portable media device, that enables users to play all kinds of content from local storage and the Internet. So there has to be connectivity. A-a-ah, not exactly. There could be connectivity, in a sense, provided someone else with the infrastructure to do it wanted to step up to the plate and provide it. Now, if you have a cell phone with Bluetooth, you could conceivably wangle something on your own. Hmm...So not exactly what we expected. But it's a touch-sensitive screen (albeit not pressure-sensitive), so there's bound to be the same types of portability software that Microsoft makes available for touch-sensitive connectivity devices like the Palm Treo. Nope, no dice. There is a nifty little program launcher, with little glass buttons that apparently go "ding" when you touch them. Oh, but that's a feature of Vista, which is coming down the road in October or so, right about the time you have to upgrade. While we're waiting for that, can we at least play a game or something on this thing? Maybe, if you'd like to download the SDK, and a free copy of Visual Basic Express, and come up with one. Six days after the official announcement of the Ultra-Mobile PC (UMPC) from Intel, and five days after its subsequent re-announcement from Microsoft, we're still left asking the same question, "What the blazes are you?" While Intel and Microsoft should be given credit for tackling the very serious issue of how to make everyday PC functionality more portable and more usable, you would think that the first iteration of what had been code-named "Origami" would have focused on form and function...or at least one of those. Pick either one. But what we have instead is something that's larger than the average pocket, that can't dial out, that doesn't have a discrete way to connect to the outside world, is somewhat expensive, and perhaps most unanticipated of all, is power-hungry. While demonstrations of UMPC devices at CeBIT in Hannover all weekend have featured the device playing movies, some observers have noted their batteries will be completely drained before the movie has finished. Some of us liked the UMPC better when it was a merrily bouncing pixilated mass of nothingness skipping over an endless array of Corbis stock footage. In search of some sensibility, we waited until the dust (or lack thereof) settled a bit, and then sought out the advice of respected analysts known for their fairness and attention to detail. We asked them the question that remained on our minds: What were they thinking? "Apparently they're thinking that the price and power efficiency and design possibilities around PCs have come to a point where they can reasonably create a second or third device for consumers, based on that architecture," answered Ross Rubin, director of industry analysis for NPD Techworld. Such an architecture, he proposed, could "enable a wide range of relatively portable applications, including movie viewing, GPS navigation, digital camera photo storage, and perhaps with the appropriate wireless connections, things like mobile Web browsing or video conferencing, or e-mail." With the appropriate wireless connections. It would appear that this is a problem, for now. In fairness, Rubin argued, that's not Microsoft's or Intel's problem right now - it's the wireless carriers'. "The challenge, particularly in the US," he said, "is that high-speed wireless data is still being rolled out by some carriers, and the components to create those connections are still relatively expensive. Certainly the service fees for those components are pretty expensive, and to integrate a radio would only enable manufacturers to appeal to customers who had a specific carrier." In other words, if the UMPC design team were to make a decision about wireless now, that decision would automatically exclude the design from being picked up by at least two-thirds of the available wireless carriers in North America. "Anyone would argue, I think, that [the UMPC] concept is a great one," stated Bob O'Donnell, program vice president for clients and displays at IDC, in response to our burning question. "I think the hype that's driven this thing forward has been because that is an appealing concept to a lot of people. The issue is, first implementations are leaving a bit to be desired, particularly on the price side." At a low price point, O'Donnell reasoned, UMPC becomes very appealing regardless of what it is, exactly. An ultimately portable device with even the promise of connectivity, at the price of an iPod, could be a sure sale. And at last, some of the infrastructure is finally in place to make such a concept feasible. "I think that concept is good, and at the right price point, it would be fine," he continued. "The problem is, when you're talking $800, $1000, now you're competing with a full-blown notebook, and that's not really what you want to do. That's the problem, but that was not the intention." What Intel and Microsoft originally wanted to do, O'Donnell explained, was to create a new category of PC that could spark its own market segment, in-between a handheld and a notebook, using relatively inexpensive, easily mass-produced components. In the intervening period while UMPC was being developed, however, the market concept of a "notebook PC" broadened, argued NPD's Rubin. Whereas on one extreme you have larger notebooks becoming popular because of their widescreen displays and multimedia capabilities, on the other extreme, there are PCs from radical designers like OQOo, featuring clamshell keyboards and swivel screens, and also the Fujitsu LifeBook with similar features and a stunning design. Currently, the LifeBook sells for prices starting at least $1400 and the Oqo Model 01+ from about $1500, which is well above the price point UMPC is staring at for now. "But there's a lot of versatility in that [notebook] market," argues Rubin, "and there's not a very thick line separating Origami devices from something like a Fujitsu LifeBook, which has a 9" screen and has Tablet PC functionality, where the screen can twist around [over] the keyboard. The LifeBook is a more expensive device, it's a thicker and larger device, but a lot of the usage scenarios today could be the same." Whereas OQO and Fujitsu have optimized for size and user appeal, Rubin explained, Intel and Microsoft have optimized UMPC for volume. "So maybe the components are not quite as cutting-edge as what's being used in the OQO," he said, "but you can build a device for quite a bit less, even if it's not quite as portable." Once the price starts working its way down to that $500 "sweet spot," then with a few new applications having (hopefully) been introduced by that time, the burden of coming up with a single compelling reason for anyone to own this thing, becomes less and less of an issue, Rubin reasoned. "To me, one of the most important things about this, is price," stated IDC's O'Donnell. "If it's under $500, it's a fancy gadget. People spend that much on iPods. So there's this sense that, at a low price point, it could be very interesting and very appealing. Think about all the free WiFi networks that are out there now that you could use this thing with, and it gives you a full browsing experience as opposed to trying to browse on a two-inch cell phone, which is a horrendously useless experience. And yet people are getting more and more used to having information access almost anywhere they are, at almost any time." Yeah, how about that ubiquitousness of information access! Oh, that's right, that part's not ready yet. "If [UMPC] had wide-area connectivity," stated Rubin, "that would have more interest to me, because then it would be easy for me to connect to my office, check RSS feeds, or send digital photos to folks from the field...that's a fairly unique application that I really don't see being met in the marketplace right now."

The allure of a wireless headset is easy to understand: it enables untethered, hands-free phone access. Often this means a mobile phone, but there's no reason why you can't use one with a conventional telephone as well. In fact, that's just what the GN Netcom 6210 headset does: it essentially puts itself in line with a conventional telephone handset so that it can be used in its place, while still allowing the conventional handset to function. It also works with any Bluetooth equipped mobile phone, and switches between the two by identifying which phone is ringing and connecting to it, or by detecting when you initiate a call with one phone or the other. You can even press a button on the top of the headset to initiate a voice-activated call. The secret to dual-mode operation is GN Link technology, which identifies the active phone and directs the Bluetooth connection accordingly. The company specs claim that the unit supports 8 hours of active talk time and up to 100 hours of standby time on a single charge. We couldn't stay on the phone long enough to push these claims to their limits, but in regular, everyday use we never had a problem with battery life, even on busy days where we stayed on the phone as much as we could. The unit also includes a small, compact charge element, the cradle of which is labeled GN even though the transformer bears the name Jabra, GN's sister company. This can replace the primary cradle/Bluetooth transceiver for those who want to take the headset on the road (though they need another Bluetooth transceiver for the headset to work). Jabra 6210 Bluetooth Headset (10 offers) Online shop Price See more products We quickly learned that the 6210 works with more than just Bluetooth-equipped mobile phones: it also worked nicely with our Dell Axim X51v (also reviewed in this buyer's guide; we used the headset profile). We used it to listen to MP3 tunes from that unit - and although one-eared sound isn't as nice as regular headphones, switching between the conventional phone and the Axim proved a better way to pass the time than with an inert headset sitting in one ear. The phone rang through the Axim connection, so we didn't miss any calls, either. The vendor claims the unit works up to 30 feet from the base station, but we weren't able to get far enough away inside our building to put those claims to the test (as soon as we walked outside, however, reception faded just as we hit the 30 foot mark). Those we talked to using the headset reported themselves able to hear and happy with voice quality, but we had occasional trouble with volume on our end of the connection. Especially in noisy conditions, the headset appears unable to crank out sufficient volume to drown out ambient noise sufficiently. That proved a pretty minor beef, since our primary place of use was in a relatively quiet office environment. The 6210 headset itself is incredibly small, a little over 4" (10.2 cm) across its longest axis, just over than 9" (22.9 cm) tracing a path all the way from the tip of the earbud to the end of the microphone boom. It's also amazingly light (0.78 oz / 22.3 g) and not too uncomfortable to wear all day long. You can switch between right- and left-earbuds to put it in the ear of your choice (the soft silicon tips pop on and off with ease). We used the GN6210 with a conventional POTS phone and also with a Motorola MPx220 and a Samsung SGH-D307 with no problems; of course, it also worked with the Axim X51v as well. Those with Bluetooth equipped mobile phones and conventional handsets should get the best use out of this unit, but it's also a workable product for those with only a single regular phone line. With prices starting at about $80 online (MSRP is about $125) this compact unit makes a great office tool for those in need of a light, compact wireless headset. The base unit also doubles as a general Bluetooth transceiver, and worked well with our Axim X51v in that role. It makes a stylish and usable gift for yourself, or anybody else who wants to get up and roam away from his or her desk while staying on the phone.

Bluetooth: A Rundown
Bluetooth is a promising technology in the making. The keenest manufacturers keep assuring us that next year will be the year of Bluetooth , no matter that they've been doing so for the last seven years. But the reality is that IT shows tantalize us with oodles of mouth-watering products that never actually hit the shelves. Logitech has had a prototype Bluetooth keyboard/mouse set since 2000, but has finally been check-mated - three years later - by Microsoft with the Wireless Optical Desktop for Bluetooth. A Brief History This wireless technology takes its name from a feat of arms accomplished by the Viking Harald Blaatand, meaning literally Harald Bluetooth , who united the realms of Norway and Denmark in a Europe divided by wars of religious and territorial dispute. This is where the originators of Bluetooth (Ericsson, IBM, Intel, Nokia and Toshiba) got their inspiration: the squabbles among too many products with too many different protocols. PCs, cell phones, PDAs, printers - every one communicates with the rest of the world via an Ethernet network, or a USB link, or else a parallel or serial port. So there is a definite need to simplify all of these different forms of communication and bring them under the umbrella of a single standard. The resultant wireless technology should link up to eight devices within a radius of ten meters, with a special focus on domestic networks for private homes: the TV with a DVD player/ recorder, which is connected to the computer, which synchronizes its data with a cell phone. Full of promise it may be, but Bluetooth technology, introduced by Ericsson in 1994, was hampered by too much incompatibility. Very few 1.0 and 1.0b standard devices could even recognize each other and exchange data, so it was practically impossible to connect two devices of different makes. Worse still, Bluetooth networks were soon found to be incompatible with WiFi ones, which, at the time, were on the same frequency band. Hence last year's WiFI (or IEEE 802.111b) migration to 5 GHz (5470 - 5725 MHz) and the release of an umpteenth Bluetooth update, version 1.1.

Cool... Pirating without torrenting ;D
This would be awesome. Bluetooth is really convenient and all, but Wi-Fi is that much more so.
mmmm, good point.
this would be nice and sounds exactly like what intel is already planning with their upcoming wi-fi stuff for the calpella platform

... What the?
Meh. I don't use Bluetooth anyway, haven't found a use for it yet.
It's good to see technologies unified, Wi-Fi Direct, Open Physics in new-gen graphics, Intel Light-Peak.
Bluetooth is useful, but one technology for all purposes is good.
Only thing I'm worrying about is interference.
Topic is >here< you --------------------> X
If you are lost on the Internets please head to google.com to orientate yourself again. Have a nice day.
Um that was for mlopinto2k1 by the way. I thought the comment would go below his.
hopefully it wont take 6 or 7 years to make it the official version.
It should kill off Bluetooth (even though I like Bluetooth as is except for high royalty causing devices to be expensive) because creating Wi-Fi devices should be cheaper.
Also, hopefully it'll use the 5 GHz spectrum as the 2.4 GHz spectrum is way too crowded.
My first thought is how will this affect battery life in portable devices? My experience has been that batteries drain like there is no tomorrow when wifi is enabled.... Bluetooth not so much.

No need to wait 2010, www.goomeo.com a mobile social network, use the same technology : file, contact, mp3 sharing between wifi mobile.

I'm not against wifi-direct but I do have one concern about it. With that more many devices using wifi such as keyboards, mouse etc, won't there be to many signals in an area? Causing a slow down in data transfers?
Jesus, think POSITIVE people! Not DEMONIC! Wait, most of you are Atheist's, who am I kidding. That means be criminals! Right?
This seems sort of off topic bud. Last time I checked though, religion had nothing to do with people doing evil things. Nutjobs come in all flavors and nothing inhibits immorality aside from choices the person makes.
\back on topic\
Any-way, I'd like to see the white papers in the near future and a chance to look over the preliminary testing.
Does this mean it would be possible for me to roam a 35,000sqft office with a wifi "headset" and still be able to get my phone calls? This would be AWSOME!My bluetooth headset has a very limited range and the entire office is "wired" for wifi.
Its about time!!!!!!!!!!!!!!! w00t!
WiFi will never take BT's place unless this new specification uses less or equal amount of energy than BT. We already have issues keeping our BT devices alive longer periods, so energy efficiency should be concern nr 1.
My opinion anyway.
sh*t, just bought a bluetooth usb device. is that the WiFi-draft-kb (kill bluetooth) specification? I'm still waiting for USB 3.0 It's supposed to be super fast, except for the implementation.
Ehhh...I'm not convinced that this will be any good. They will have to sacrifice range for power efficiency, which puts the wireless accessories back into Bluetooth territory (either that or we'll be recharging our mice and keyboards several times per day). Wireless USB will be the way to go if it ever gets standardized and makes its way to the market.
I don't get why wifi chips can't just enable bluetooth. Doesn't bluetooth run on a small range of radio frequency that wifi could handle (2.4GHz)?
Oh yeah, patents and licensing...
I was never a big fan of bluetooth. Something about taking 30 minutes to send a 6 mb file just doesn't feel exciting.
Excellent news and sounds as if cheaper to also be implemented
Yeah, having the bandwidth, distance and single protocol advantages of WiFi over Bluetooth definitely make this a no-brainer.
