drag2share: Researchers demo full-duplex wireless: double the throughput with no new towers

Melissa Duarte, Rice UniversityBack in February researchers at Stanford first taunted us with the possibility of simultaneous, two-way data transmission on the same frequency. Now some folks at Rice University are edging full-duplex communication closer to reality. By the time carriers get around to rolling out 4.5G networks, engineers could potentially double throughput without adding more cell towers and using only existing mobile hardware. With an extra antenna and some fancy software tricks, which allow the device to ignore locally produced signals, the Rice team was able to produce a connection ten-times stronger than previously published studies. Since the technology is based on existing MIMO setups, it may also prove the shortest route to asynchronous full-duplex transmissions. That means you'll be able to upload ill advised videos of your drunken antics (and suffer the consequences) that much faster, without having to pause the latest Maru clip. Check out the PR after the break.

drag2share: Samsung Stratosphere makes its obligatory FCC visit, confirms membership in Verizon's LTE club

We know, the image above is hardly as detailed as the ones we glanced at this morning, but it has its measure of significance nonetheless. It's a rough diagram of the Samsung SCH-i405 -- a phone known to us as the Stratosphere -- as it appears in FCC filings approved today. The documents' mention of LTE band 13 (as well as CDMA / EVDO) seems to confirm rumors that suggest the aforementioned device will be coming to Verizon's 4G network, likely sooner rather than later. If you've been eager to see an Epic 4G-esque QWERTY slider on the largest carrier in the US, this will be your golden opportunity. Of course, this may prove to be a drop in the bucket when compared to an impending flood of even more tempting handsets.

drag2share: TiVo Premiere Elite will bring quad tuners, 2TB storage to retail this year

Source: http://www.engadget.com/2011/09/07/tivo-premiere-elite-will-bring-quad-tuners-2tb-storage-to-retai/

When TiVo announced its first quad tuner DVR, the Premiere Q, fans were devastated to learn it would only be available via cable operators, and that it featured a smallish 500GB hard drive. Fortunately, the company has rectified both of those issues by announcing the TiVo Premiere Elite, a quad tuner Series 4 DVR with 2TB of storage built that will be available through TiVo.com, Best Buy's Magnolia stores and authorized home theater installers. There's no word yet on price or an exact release date, as all of this is still pending a waiver from the FCC allowing TiVo to sell the box without any OTA or analog cable tuners, making this a digital cable (or Verizon FiOS) only experience. It's also THX Certified and most of the press release is dedicated to focusing on the high end nature of the hardware TiVo is unleashing. Also unmentioned so far is any retail edition of the TiVo Preview multiroom extender box, but we should get some hands-on time with this quad tuner edition very shortly during CEDIA 2011. For now, just check out the press release, included after the break, and for our European readers Engadget Spanish has you covered on the launch of the TiVo Premiere for ONO in Spain.

Update: The official TiVo.com/elite page is live, and reveals the price as $499 "with service", $499 additional for a lifetime subscription. [Thanks @PhilipSaad]

drag2share: Seagate plays the 4TB card with its GoFlex Desk external HDD, shipping now for $250

That tangled mess of a backup solution feeling a little cramped? Yeah, join the crowd. Seagate's looking to give you a dash of capaciousness -- a dash that you could desperately used -- with its newest desktop HDD. The GoFlex Desk line is about as sleek as it gets for a non-mobile drive, with 1/2/3/4TB options being made available. The stock model ships with USB 2.0 / 3.0 support, a required AC power adapter (blah) and support for OS X and Windows platforms. The entire unit weighs but 2.38 pounds and checks in at 6.22- x 4.88- x 1.73-inches; true to the GoFlex name, the lower base can actually be swapped out for those who'd prefer a different interface (you know, like FireWire or Thunderbolt), and there's a four-LED capacity gauge on there as well. In our limited testing, we consistently saw USB 3.0 burst rates top 100MB/sec, while sustained transfers hovered closer to 60MB/sec. When used on a USB 2.0 rig, we saw reads and writes hover between 30MB/sec and 40MB/sec. As for pricing and availability? The 4TB flagship can be found right now at Seagate's site for $249.99, while the GoFlex Desk for Mac -- which touts both Firewire 800 and USB 2.0 -- will be available in Apple stores by the end of the month. We're told that Thunderbolt will be supported once that GoFlex adapter is let loose, but an ETA isn't quite ready for public eyes.

drag2share: MSI's reverse fan tech keeps dust out, graphic cards chilled

Source: http://www.engadget.com/2011/09/07/msis-reverse-fan-tech-keeps-dust-out-graphic-cards-chilled/

We've all been there, trying in vain to remove dust caked onto the fans of componentry inside our rigs. It's mostly a fruitless endeavor, but here to save us from the horde of dust bunnies invading our graphics card is MSI's dust removal technology. Available on the company's "Lightning Xtreme" edition of the GTX580, soot is annihilated by spinning that card's fans at full throttle in reverse for thirty seconds after boot. That's apparently an effective method for flinging accumulated grime off the spinners and (hopefully) into a spot you can actually reach. Unconvinced it'll work? Well then, mosey on over to the source link bub, and prepare yourself for video proof of the fan-powered filth evisceration.
