Mulit-gigabit Wi-Fi is here and 5 reasons it matters

shaun — Thu, 05 Jan 2012 13:14:22 +0000

Broadcom is expected to show off silicon that offers 1.8 gigabit per second Wi-Fi at this year’s Consumer Electronics Show. The technology will help prepare home networks for the era of whole-home video streaming. To promote the chips, which will use the 802.11ac standard, Broadcom has highjacked the G used by cellular networks, calling the new standard 5G Wi-Fi.

Terminology aside, here’s why this latest iteration of Wi-Fi is so cool:

It’s fast. The standard can deliver up to 3.6 Gbps around the home, although initial chips offer 1.8 Gbps. The current top-of-the-line Wi-Fi chips (802.11n) top out at 600 Mbps.
It’s designed for video. The technology uses the 5 gigaherz band as opposed to the 2.4 gigaherz band. The gigahertz band has wider channels to deliver more capacity and competes with fewer other wireless devices, which means the channels can carry more data such as fat high-definition and maybe even 3-D video streams.
It’s designed for multiple devices and concurrent streams. Those wider channels also mean a home can support more devices trying to send lots of data, such as sending multiple, concurrent HD video streams around the home, while someone else plays a game or video conferences. So while you might not think you need a gigabit home network without a gigabit pipe leading to your home, if you’re streaming cached content from a hard drive or another device, this helps.
It’s more power efficient. The wider channels allow for more data to travel over the network, which means downloads take less time. At that point the radio powers down to save on battery life or power. This doesn’t help when streaming, but would be good for keeping devices and hard drives synced.
It goes the distance. The physics of transmitting data using airwaves over distances and through certain materials doesn’t change, but because the standard can deliver faster speeds from the router, folks will get proportionately faster speeds as they move away from the router in their homes and offices. It also uses beamforming technology (basically it compresses the signal like a laser compresses light to make it more powerful) to better pass through buildings, especially through those made of concrete. The end result is a better signal even if it must pass through a few walls — and a decent end-user experience.

Broadcom expects to start shipping chips in the middle of this year and appearing in a wide variety of products from phones and laptops to set-top-boxes and home routers that will ship in the second half of the year. In November Quantenna, a chipmaker startup that has raised more than million, announced its own 802.11 ac chips, and in September I spoke with Craig Barratt, president of Qualcomm Atheros about that chipmaker’s vision for the next generation of Wi-Fi.

Samsung Stratosphere review

shaun — Sat, 17 Dec 2011 15:14:22 +0000

Once upon a time, in the not-so-distant past, Verizon was still in phase one of its LTE lineup, which consisted of nothing but 4.3-inch slate phones with questionable battery life and very little to stand out from the rest of the competition. Now that we’re seeing the second generation of devices coming into the 4G fold, Big Red appears to be pushing choice — not just in terms of size and feel, but price as well. The Pantech Breakout was the first to, well, break out of the mold, offering a smaller form factor for a much more reasonable cost. It was nothing to write home about, but the fact that it existed gave us hope that we’d see a slew of phones in the same price range, finally making high-speed connectivity a more affordable option.

Shortly afterward, the Samsung Stratosphere sneaked up and snatched the spotlight away from Pantech, offering the very first QWERTY keyboard on an LTE-capable device for a cost similar to that of the Breakout. But when we first saw the phone, something felt eerily familiar: it looked almost exactly like the Epic 4G, a Galaxy S-era device that was released on Sprint’s WiMAX lineup nearly a year and a half ago. Looks are one thing, but what about the internals? Does the brand new Stratosphere perform like an old phone, or does it give a completely fresh perspective on a 2010 classic? Read on for the full scoop.

A few of our favorite things: Power accessories

shaun — Sat, 17 Dec 2011 13:14:36 +0000

This holiday season, we’ll be running a series of weekly features called “A few of our favorite things,” where we round up some gift suggestions based on the gear that has passed through our offices either for review purposes or through personal purchases. We’ll tell you what we think is the best gear out there, for a variety of product categories and budgets.

Shopping time is almost up for this year’s holiday season, but shipping deadlines have yet to elapse completely, and stores will still be plenty busy. In this week’s installment of our ongoing series, we’re looking at power accessories for Apple devices that could make great last-minute gifts and/or stocking stuffers.

Best backup battery: Just Mobile Gum Plus. There are a lot more solid options in this category than there were, say, a couple of years ago. But the Just Mobile Gum Plus wins for a number of reasons, including its high capacity (4400 mAh, enough for up to three charges for your iPhone), good looks and small, easily pocketable or stowable design. The Gum Plus is .95 plus shipping.

Best iPhone battery case: Mophie Juice Pack Plus. The iPhone battery case market is likewise crowded, but there are a few that have stood the test of time, and the Mophie Juice Pack Plus is one of them. Even considering the unfortunate recall that happened this year with its iPod touch model, the Juice Pack Plus is the best-in-class when you’re looking for something for your iPhone 4 or 4S extra battery life needs, because of its 2000 mAh capacity and pass through volume and sleep/wake controls. The Juice Pack Plus retails for .95.

Best charging adapter: PlugBug. The PlugBug from twelveSouth is a clever and invaluable add-on for people with a variety of Apple mobile devices. It’ll help convert your MacBook adapter so that it can also do double duty and charge your iPhone or iPad at the same time from the same outlet. Plus it can act as a standalone iPad charger and comes in an eye-catching red design that makes it harder to miss when you’re doing that final visual sweep of your hotel room. At the Apple store online, the PlugBus is .95

Best charging cable: The Magic Cable Duo. Innergie’s clever little cable with in-line, swappable 30-pin Apple dock connector and micro USB is able to charge pretty much any modern mobile device, including the above-mentioned Mophie Juice Pack Plus, as well as any Apple iOS gadget. The Magic Cable Trio adds mini USB to the mix, but we’re willing to bet that for most up-to-date gadget geeks out there, the Duo will cover all the necessary bases. The Magic Cable Duo sells for .99 on its own.

That’s our list, but feel free to argue our choices or voice your own suggestions in the comments.

Intel springs another leak, mobile Ivy Bridge CPUs abound

shaun — Wed, 07 Dec 2011 05:14:24 +0000

Just yesterday, we caught a glimpse of what Intel has in store for Ivy Bridge, and it seems those details were but a prelude to a bevy of details that leaked out today. It seems the folks over at VR Zone got their hands on some of Chipzilla’s internal documents showing a host of changes for its post-Sandy Bridge mobile CPUs. Apparently, we can expect quite a few new full-power models, including a 2.9GHz Core i7-3920XM — clocked at 200MHz faster than the Core i7-2960XM that’s Intel’s presiding mobile chipset champion — along with two other quad-core Core i7s and a couple of Core i5 chips as well. For those who cherish battery life above all else, there’s a dual-core Core i7-3667U clocked at 2.0 GHz and a 1.8GHz Core i5-3427U coming down the pipe. All the speedy new silicon comes with upgraded Intel HD 4000 graphics, and is slated for release in April and May of next year. If you can’t wait until then for your next-gen CPU fix, head on over to the source for a heaping helping of Ivy Bridge charts and specs.

Carrier IQ Admits Holding ‘Treasure Trove’ of Consumer Data, But No Keystrokes

shaun — Sat, 03 Dec 2011 03:14:19 +0000

MOUNTAIN VIEW, California — An embattled phone-monitoring software maker said Friday that its wares, secretly installed on some 150 million phones, have the capacity to log web usage, and to chronicle where and when and to what numbers calls and text messages were sent and received. The Carrier IQ executives, speaking at their nondescript headquarters in a residential neighborhood in the heart of Silicon Valley, told Wired that the data they vacuum to their servers from handsets is vast — as the software also monitors apps deployment, battery life, phone CPU output and data and cell-site connectivity. But, they said, they are not logging every keystroke as a prominent critic claimed.

Amazon Kindle Fire review

shaun — Mon, 14 Nov 2011 05:14:22 +0000

It seems like ages since Amazon introduced us to the 9 Fire at a hectic New York City event, but in truth that was only about six weeks ago. Maybe our perception of time is warped because we’ve been hearing talk about this 7-inch Android tablet for months now. Maybe it’s because Amazon launching a tablet seemed like such a natural thing to do after Barnes & Noble paved the way with its Nook Color. Or, maybe it’s just because the gadget Amazon shipped looks nigh-identical to the 7-inch BlackBerry PlayBook that we’ve had for, well, ages.

For whatever the reason, what Amazon has delivered is a device that is intimately familiar yet mysterious — a simple, minimalistic exterior design hiding a flashy, seemingly quite trick customization that’s sitting atop a decidedly ho-hum Android Gingerbread build. Our questions leading up to this review were many: How will it handle sideloading? Are the battery life and performance better than the PlayBook? Can a tablet that costs two hundred bucks stand a chance against those that cost two and three times as much? C’mon baby, click on through to find out.

Transformer Prime detailed: 10-inch Super IPS+ display, 12-hour battery and quad-core Tegra 3, ships in December for $499

shaun — Wed, 09 Nov 2011 07:14:23 +0000

For three weeks now, Android fans have been fidgeting impatiently. Specifically, ever since ASUS chairman Jonney Shih took the stage at last month’s AsiaD conference and teased the next-gen Transformer tablet. Though he only gave us a quick glimpse, he recited a laundry list of specs: a 10.1-inch display, 8.3mm-thick body, mini-HDMI output, microSD slot and an update to Ice Cream Sandwich by the end of the year, if not sooner. Not to mention, it’ll be the first tablet packing NVIDIA’s hot-off-the-presses Tegra 3 SoC, making it the first-ever quad-core tablet. We knew this: we’d learn more on November 9th.

Well, that day has come, and so have the juicy details. We just got word that the tablet will go on sale worldwide in December, starting at 9 with a beefy 32GB of storage, moving up to 9 for a 64GB model. (That signature keyboard dock you see up there will cost 9.) In addition to those basic specs Mr. Shih revealed last month, we now know this has a 1280 x 800, Super IPS+ Gorilla Glass display with a 178-degree viewing angle and a max brightness of 600 nits. It also packs 1GB of RAM, GPS, a gyroscope, SonicMaster audio and a 1.2 megapixel front-facing camera. Rounding out the list is an 8MP shooter with an auto-focusing f/2.4 lens and a back-illuminated CMOS sensor that captures 1080p video. Touch-to-focus is also an option here, and ASUS claims a 30 percent boost in color enhancement over competing tabs.

As for battery life, we initially heard reports of 14.5-hour runtime, but ASUS is now saying the tablet alone can squeeze out 12 hours thanks to a 22Wh battery, and that the dock will add an additional six hours of juice. In addition, the slimmed-down, 1.2-pound dock brings all the other benefits the last-gen model offered, including a touchpad, USB 2.0 port and full-sized SD slot. Software-wise, it’ll ship with Android 3.2 and apps such as SuperNote and Polaris Office, and we’re told we’ll learn more about that ICS update in “early December.”

In terms of design, you may have already noticed the Prime sports the same spun aluminum digs as the company’s Zenbooks, though this is the first time we’re seeing clear, close-up shots of it — and in two colors, no less! At 8.3mm (0.33 inches) thick and 586 grams (1.29 pounds) without the dock, it’s a smidge skinnier than the iPad 2 and Galaxy Tab 10.1, which means, unsurprisingly, that your old Transformer dock won’t be compatible. Finally, ASUS coated both the display and metal cover with a hydro-oleophobic coating that makes it more fingerprint-resistant. For now, we’ve got photos below and if you can wait a few more weeks, we’ll most definitely be putting this thing through its paces in a full review. And if you’re looking for something a little less expensive, well, the original Transformer should be getting Ice Cream Sandwich soon, and we wouldn’t be surprised if Santa brought a few holiday rebates.
