  • Qualcomm's Peanut challenges ZigBee, Bluetooth for control of your personal area network next year

    Perhaps dissatisfied with the glacial pace of Wibree, Qualcomm's working on an ultra-low-power, short-range wireless transfer tech of its own -- it's called Peanut, and executives claim it only needs "fractions of a milliwatt of power" to push data at several megabits per second. Computerworld got the scoop on the new low-power radio at EmTech@MIT 2010, and reports that Qualcomm's had these goobers in the oven since 2006 and is looking to trump the likes of ZigBee and Bluetooth by this time next year. Assuming, of course, the Peanut standard doesn't require a molasses-like committee of its own to attain formal approval.

  • Bluetooth 4.0 specification gets official, devices expected by Q4 2010

    Outside of Samsung's Wave, we're having a hard time thinking of a meaningful device that has shipped with Bluetooth 3.0 onboard. Kind of crazy when you think about it, being that the protocol offered some pretty promising stuff when it went official in April of 2009. Fast forward to today, and it looks as if the Bluetooth SIG is storming forward regardless, as the Bluetooth 4.0 core specification has now been adopted with "low energy technology" as the standout feature. This step means that companies can begin to work towards integration of BT 4.0 in actual end-user products, and if the SIG has its way, the tech will begin to show up in minuscule devices that haven't been able to take advantage of Bluetooth thus far. In fact, they want this stuff in applications "not even possible or imagined today." Looks like someone better get those imagination gears turning, 'cause Q4 2010 certainly isn't an eternity from now.

  • Bluetooth 4.0 with low energy (almost) finally ready to roll

    Molasses, snails and glaciers: none are slower than an organization developing a new wireless standard. The Bluetooth Special Interest Group (SIG) is no exception -- it's been nearly three years since it announced it would roll Wibree into Bluetooth and four months since it made Bluetooth 4.0 official, but still no dice. This week, the SIG says the low-power specification is ready for action, its minutiae finalized. However, fine print in the org's press release disagrees. The main reason for Bluetooth 4.0 was to include lower power devices, but that all-important integration is still pending a "before June 2010" completion date. That means we still won't see Bluetooth-toting cats till the end of the year, and we have no idea what SIG has accomplished in the meanwhile. Press release after the break.

  • Bluetooth 4.0 devices to make the scene later this year

    We were glad to see Bluetooth low energy actually added to the Bluetooth 4.0 spec, but of course the question remained: when are we going to get our hands on it? By Q4 this year, apparently -- at least according to the Bluetooth SIG. But don't expect any dramatic changes in battery life for most of your gadgets: while the low energy spec introduces connectivity to a host of lower-power devices that have in the past relied on proprietary technology (such as watches, pedometers, and cats), your traditional Bluetooth devices, such as phones and laptops, will consume roughly the same amount of power. Indeed, the low energy spec is merely throwing smaller devices (with smaller amounts of data to transfer) in to the mix: if you want Trans-Siberian Orchestra to sound as glorious as ever on your wireless headphones, you'll need to push as much data (and hence draw as much power) with version 4 as you would with version 3. If you've ever heard "A Mad Russian's Christmas," you'd know what we're talking about.

  • Bluetooth 4.0 finally rolls low energy tech into a shipping standard

    Bluetooth low energy and its predecessors (think Wibree) have been in the pipe for ages now, but we might actually see this tech take off en masse for the first time now that the Bluetooth SIG has officially added it into a release: 4.0. While Bluetooth 3.0 was all about high energy with the introduction of WiFi transfer, 4.0 takes things down a notch by certifying single-mode low energy devices in addition to dual-mode devices that incorporate both the low energy side of the spec plus either 2.1+EDR or 3.0. In a nutshell, the technology should bring a number of new categories and form factors of wireless devices into the fold since 1Mbps Bluetooth low energy can operate on coin cells -- the kinds you find in wristwatches, calculators, and remote controls -- and the SIG's pulling no punches by saying that "with today's announcement the race is on for product designers to be the first to market." Nokia pioneered Wibree, so you can bet they'll be among the frontrunners -- bring it, guys.

  • AMD 's new Athlon II processors aim to go easy on the power, your wallet

    AMD has just outed a selection of new Athlon II procs, which do little to help it reclaim the performance crown, but will be of interest to anyone who likes to keep things minimal -- whether we're talking about prices or temperatures. Starting at $69 per chip (when bought in bulk) with the 2.7GHz dual-core X2 235e and topping out at $143 for the 2.3GHz quad-core X4 605e, AMD's new e-tagged processors operate within a 45W thermal envelope, as opposed to the relatively standard 65W TDP. The Sunnyvale outfit makes some ill-advised claims of "up to 75 percent" better performance versus comparable Intel CPUs -- the small print tells us that number is derived from 3DMark Vantage while testing with different GPUs -- but we suppose until the Thuban six-core shows up, AMD will have to take performance gains from wherever it can get 'em, including its own imagination.

  • Texas Instruments CC2540 promises ultra-low energy Bluetooth

    Texas Instruments is pretty chuffed with itself right about now, as it's prepping to demonstrate a swell-sounding new system-on-chip that takes Bluetooth connectivity to the extreme reaches of low energy consumption. About to be shown off in Munich tomorrow, the new CC2540 takes up a measly 6mm-squared of real estate, and is said to be able to operate for more than a year on a single button cell battery. With the reduced physical size and embedded Flash memory, this should be easier to install and update as necessary too. Considering the battery-draining ways of current Bluetooth tech, such claims sound preposterously awesome, but we'll keep our giddy enthusiasm in check until early next year when samples will begin rolling out. For now, you can check out the older video below 'splaining the prospective benefits in more detail.
