Tizen 1.0 Larkspur arrives, fuels your open-source phone dreams
The unveiling of Tizen left many mobile open-source aficionados wondering when the OS would reach its all-important 1.0 status. The answer is now: the coalition between Intel, Panasonic, Samsung and a raft of carriers has posted the first non-beta release in both source code and software development kit forms. The finished versions of either carry new features to reward developers for the wait: SDK users get a new browser-based simulator and a faster emulator, while those scouring the source code will find new point-of-interest and route searching features in location-aware apps as well as WiFi Direct and more HTML5 support. About the only wait left is for an actual Tizen phone to ship. [Image credit: Realnorth]

Samsung Galaxy S II review
If you don't already know all about the Samsung Galaxy S II, where have you been the past two months? The successor to one of the most popular Android handsets to date carries a burden of expectation almost as sizable as its 4.3-inch Super AMOLED Plus screen. It promises to be thinner, lighter, and faster than the Galaxy S that preceded it, while garnishing Android 2.3.3 with a set of TouchWiz customizations that might actually enhance, rather than hinder, the user experience. As such, the Galaxy S II earns Samsung full marks for ambition, but does this slinky new smartphone live up to its interstellar hype? The answer, as always, can be found after the break. %Gallery-122444%

Bigfoot brings Killer bandwidth management to laptops via Wireless N module
Good news for the Bigfoot faithful -- the bandwidth management technology that's been making your desktop gaming experience smoother for years is just about ready for the laptop sector. When we spoke with the company's leadership back at Computex, they hinted strongly that infiltrating the mobile gaming space was a top priority, and it seems as if the stars have finally aligned for that to happen. The company's new Killer Wireless-N 1103 and 1102 half-size mini-PCIe adapters are suited for use in pretty much any laptop on the market, with the primary difference between two being available streams: the former utilizes three-stream MIMO for data rates as high as 450Mbps, while the latter relies on a two-stream MIMO setup capable of pushing 300Mbps. Both units will have Advanced Stream Detect and Visual Bandwidth Control, which should make your wireless gaming and videocall sessions smoother, more reliable and more predictable, regardless of what the network situation is. We're still waiting in tense anticipation for who Bigfoot plans to partner with here, but we're guessing that the gaming mainstays will be all over this in no time flat. Keep it locked for more as we get it. Update: Looks like Bigfoot has come clean with its partner lineup. Killer Wireless-N adapters will be introduced this month inside gaming and media notebook PCs from leading vendors including AVA Direct, CyberPower, iBuyPower, Maingear, Origin PC, Sager, The V-Machine, Velocity Micro and others.

Qualcomm's FlashLinq long-range peer-to-peer communications tech demoed at MWC (video)
Taken a look at our AllJoyn hands-on here at Mobile World Congress? You should, and then pick up here. Back? Good. Qualcomm's FlashLinq is a quasi-extension of AllJoyn, but unlike the latter, this is a proprietary solution that actually requires Qualcomm hardware to run (for now anyway; licensing deals could be in the works). Basically, this wireless technology allows FlashLinq-enabled devices to sense up to 4,000 other FlashLinq devices within a radius of up to 1km, which puts things like WiFi and Bluetooth to shame. Of course, that's under "ideal" circumstances, but even in subpar situations, the range should still beat out existing short-range alternatives. Why develop a solution like this? For one, businesses will be all over it; imagine a Yelp! instance that specifically hones in on businesses that have a FlashLinq-enabled device in their store, which is advertising deals for those who stop in and mention that FlashLinq sent 'em. Secondly, social networking / Latitude addicts will be head over heels for something like this. Once a connection is made, there's a steady 15Mbps beam available between the users -- that's more than enough for videochats, media streaming and multiplayer gaming. The major difference between this and WiFi (aside from the range) is that unlike WiFi -- which operates in unlicensed spectrum -- FlashLinq requires licensed 5MHz TDD spectrum. That enables control over interference, which in turns boosts range and device density. Moreover, this system uses dramatically less power than BT or WiFi to sense other devices -- you're only using power for discovery two percent of the time, we're told. Beyond that, a lot remains up in the air. The company is still hammering out which chips will ship with FlashLinq support, and it'll be waiting for results from its SK Telecom trial (which starts in April) before committing to a commercialization date. Sadly, none of this can be retrofitted into older devices, but the good news is that it's hardly limited to mobiles. FlashLinq-enabled televisions, laptops, in-car infotainment systems, etc. could all be used to create a discoverable network of interactive goodness, but of course, it's hard to say how much success Qualcomm will have in a world already loaded down with connectivity options. The technology itself is fairly fascinating, though, as is the social networking demonstration that's embedded just past the break. Hop on down and mash play, won't you? %Gallery-116870%

Qualcomm demos AllJoyn peer-to-peer sharing / gaming technology (video)
It's simple, but highly complex. You dig? Qualcomm's AllJoyn demonstration here at MWC was quite the eye-opener, but it's hard to say how much traction it'll gain in a world already inundated with short-range transfer protocols. Bluetooth, Infrared, Wi-Fi Direct... the list goes on and on (and on). Essentially, AllJoyn is an open-source software system that doesn't actually have to run atop Qualcomm hardware; if implemented in a particular app, it can enable peer-to-peer sharing with others based on location. If you're standing near someone who also has an AllJoyn-enabled application, you two (or more) can interact -- if you're both using Bluetooth, the range will be around 30 feet, but if you're both using Wi-Fi, it'll obviously be greater. Qualcomm's hoping to entwine its homegrown FlashLinq (more on that in a separate article) in order to let people use this while being up to 1km away from one another. The company describes AllJoyn as a software framework for developers that enables easy P2P access; rather than an app developer having to write this functionality in from scratch, they can simply grab Qualcomm's code and integrate it. Currently, the spec only supports Bluetooth and Wi-Fi, but Wi-Fi Direct and FlashLinq support it in the works, and those will hopefully be added by the end of the year. We're told that the company's also working to create a constant link between devices, which could one day (soon) enable streaming support. There's C++, Java and Javascript models available, with Qualcomm's goal being to have developers port this all over the place. The demo (embedded after the break) involved a foursome of phones sharing photographs with one another, while a nearby laptop was shown engaging in a multiplayer game with two smartphones. We were told that the company's currently in talks with a number of large gaming firms to get this ingrained in future titles, but no specifics were available. Another application would be within a social network, enabling AllJoyn apps to alert users when a friend is nearby. A huge boon there is that this doesn't require data, so international groups who'd like to keep tabs on one another's location will be able to do so without roaming on a foreign network. So, any app developers considering bundling this in with your next update? %Gallery-116868%

SQ Blaster Pro is a WiFi, Z-Wave, and IR blaster home automation powerhouse
We've seen plenty of IR blasters around the Engadget trailer but few, if any, include WiFi and Z-Wave home automation radios. But that's exactly what the boys over at Square Connect have planned as a followup to their existing SQ Blaster product. A trick that lets you control your home theater equipment, window coverings, lights, and HVAC systems from the company's own SQ Remote iPhone app. At least that's the plan when it ships sometime around Q2, possibly touting WiFi Direct capability and Wi-Fi Protected Setup (WPS). The device above is a non-working prototype that just happens to look nice with the Apple TV. It features cutouts for a USB port (power and setup), IR extenders, built-in blasters, and removable antenna. Working models are already in field testing with shipments expected to land in the homes of consumers sometime in Q2. %Gallery-113322%

LG Optimus Black shows off its WiFi Direct skills on video (hands-on)
WiFi Direct, for those not paying attention in class, is a communications protocol for allowing devices with wireless radios to talk to one another and share files without the need for an intermediary WiFi access point between them. Basically, it's like blasting out an ad hoc wireless network, one that permits simultaneous file transfers to up to eight other WiFi Direct-capable machines. LG kindly gave us a peek at its implementation in the Optimus Black, and while things are still pretty rough and (not) ready, we got a decent idea of how they'll operate. Jump past the break to see for yourself. %Gallery-113287%

WiFi Direct helps you kill space chickens without an access point (hands-on)
The urge to kill a chicken is surprisingly strong when operating in the dead space between sleep deprivation and a caffeinated buzz of hyper alertness. The fact that the beast is giant and in space makes it downright compulsive especially when given the opportunity to team up in combat with Max Planck over an 802.11n WiFi Direct connection... without an access point and without any lag. This isn't your father's Bluetooth connection, son. See the carnage go down after the break.

LG BD690 is the first Blu-ray player certified for Wi-Fi Direct, keeps Bluetooth paranoid
The possibilities teased in 2009 by Wi-Fi Direct have probably kept Bluetooth up at night, and we're sure the commencement of device certification last month hasn't helped, either. Now the LG BD960 has emerged as the first Blu-ray player on the Wi-Fi Direct certification list, hinting direct P2P communication in our home theaters among WiFi devices (without the need for a routing middleman) could soon go from fiction to fact. Unfortunately, mum's still the word on shipping and pricing. The mere chance however that the player could stream content to any other WiFi-equipped device -- Direct certified or not -- is a big enough deal to give our dedicated media streamers Defarge-like glances already. Particularly, if the BD960 comes packed with features similar its suspected predecessor the LG-BD390, which can stream both Netflix, Vudu, and DLNA network content, as well as play DivX HD 1080p content. Until more details surface though, we'll simply have to keep reminding our poor Galaxy S that it isn't destined to be alone in this cold, cruel world forever.

Samsung Galaxy S first smartphone to be Wi-Fi Direct certified
Samsung has generally been on the cutting edge when it comes to giving its smartphones the latest and greatest in terms of compatibility, with the Omnia being the first DivX certified handset in America this month two years ago. Now, it's looking to wrangle yet another first, with this one having the potential to be far more important. The outfit's hot-selling Galaxy S smartphone (GT-I9000) is now listed on the Wi-Fi Alliance's Wi-Fi Direct certification docket, and while we knew that a handful of Wi-Fi modules and chipsets were about to get green-lit, this marks the first actual device to join that crowd. As we mentioned before, any modern-era WiFi device is capable of becoming Direct certified (via a firmware update given that there's no hardware change in the protocol), but it seems as if Sammy is being Johnny-on-the-spot. We'll keep an ear to the ground regarding an actual update that brings this functionality to life, but for now, let's all cross our fingers and hope those other phone makers get their handsets in line, too.

Wi-Fi Direct certification begins today, device-to-device transmission starting soon
So, Bluetooth -- last fall didn't end up being as frightful as you had probably imagined, but this fall is bound to be different. Or so the Wi-Fi Alliance says. If you'll recall, Wi-Fi Direct promised to do what Bluetooth had been doing for years, but with far less fuss and on a protocol that's much more widespread. A solid year has come and gone, and we've heard nary a word from any company who plans on implementing it. Thankfully for us all, that changes today. Starting in mere moments, Wi-Fi Direct devices will begin the certification process, and while we couldn't extract exact product details or a release time frame for future wares on a media call regarding the announcement, we did get the impression that at least a few partners were trying to get Wi-Fi Direct wares onto shelves before Christmas. As for functionality, the claims are fairly impressive. In order to make a direct device-to-device connection over WiFi, just one of the two need to be Wi-Fi Direct certified. In other words, a Wi-Fi Direct printer can recognize and interface with your Latitude D410 laptop from 1999, as all Wi-Fi Direct certified devices have to be able to control the one-to-one relationship. The goal here is pretty simple -- it's to create a protected connection between two devices over WiFi with as little hassle as possible. Think Bluetooth, but using WiFi. We also learned that "most" products certified will also support "one-to-many" connections, enabling a Wi-Fi Direct laptop to be in contact with a printer, connected HDTV and a tablet simultaneously, with no router in-between at any point. We should also point out that while 802.11a/g/n is supported over 2.4GHz and 5GHz bands, there's no requirement for Wi-Fi Direct products to support 802.11b, so legacy users may want to pay attention to that quirk. There's also no new hardware requirements here, so in theory, any existing WiFi chipset could be upgraded via firmware to handle Wi-Fi Direct -- whether or not that'll happen on a large scale was a question the Wi-Fi Alliance couldn't answer for us. Finally, they noted that the app ecosystem is likely to make this whole rollout a lot more interesting, particularly considering that Direct is simply a pipe that software can dictate as it sees fit. We'll be keeping a close eye on the developments here; we've waited way too long for this to blossom, but we're pretty jazzed about the possibilities. Head on past the break for a video overview of how Wi-Fi Direct works.

Wi-Fi Direct to bring secure peer-to-peer networking in 2010
If there's one thing that I've wanted to be able to do for years, it's to set up a direct Wi-Fi connection to another device without having to actually be near a Wi-Fi base station, or going to the trouble of getting an ad-hoc network set up on both devices. This type of peer-to-peer networking is nothing new; back in the Newton MessagePad days we could beam address cards and data between devices through an IrDA connection. Now the Wi-Fi Alliance has announced that this will be possible next year through the use of Wi-Fi Direct. Wi-Fi Direct will come built into many new devices and can be implemented in existing devices through software updates. Wi-Fi Direct competes directly with Bluetooth, and will provide much faster data transfer speeds (using more power, unfortunately). According to the Wi-Fi Alliance, "The specification, previously code-named 'Wi-Fi peer-to-peer,' can be implemented in any Wi-Fi device, from mobile phones, cameras, printers, and notebook computers, to human interface devices such as keyboards and headphones. Significantly, devices that have been certified to the new specification will also be able to create connections with hundreds of millions of Wi-Fi CERTIFIED legacy devices already in use. Devices will be able to make a one-to-one connection, or a group of several devices can connect simultaneously." I can imagine that at some point in 2010, we'll be able to sync our iPhones using Wi-Fi Direct, directly send address book information to other iPhone-toting people, and enjoy high-speed multi-player gaming fun. Apple is a sponsor corporation for the Wi-Fi Alliance, so adoption of Wi-Fi Direct on Macs, iPhones, and future Apple equipment will hopefully be swift and widespread. [via MacRumors]

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