AT&T and Cisco have WiFi on the cable box backwards

Adding WiFi to a cable set-top box is probably something every geek has thought would be a great idea, but we suspect you and AT&T aren’t on the same page. You were probably thinking it’d be cool to stream viral internet videos to the big screen without switching inputs, or maybe you thought it’d be cool to ditch the cable modem and WiFi access point and feed your laptop internet via the same box you deliver your HD with. Nope, AT&T and Cisco obviously don’t think those are worthy ideas, and instead, this new box simply works without a coax cable. We suppose there’s a market for this as only like 90 percent of TVs have coax running to them already — and no new house is built these days without ’em — but we have tried to stream HD via WiFi and it shouldn’t come as much of a surprise that it doesn’t “just work.” Of course the fact that U-Verse’s H.264 streams are pitifully over-compressed should help, but even when you add that to the great performance of 802.11n, we suspect you’d still be better served by a good ol’ copper wire.

AT&T Mobile Hotspot for iPhone 4 limited to just three WiFi devices (update: it’s an iOS 4.3 thing)

Say it ain’t so! According to this here slide, which details a bit of insidery AT&T information about the impending release of iOS 4.3, Ma Bell’s iPhone 4 will have its Personal Hotspot restricted to use with just three devices. Just about every MiFi / mobile hotspot device we’ve ever seen — including Verizon’s iPhone 4 — has supported five WiFi devices, but unless AT&T pulls a 180 here, it’ll be limiting its iPhone to just three connections. What’s wild is that we’ve found AT&T to actually have superior 3G speeds when you can actually get a signal (and thus, be more conducive to tethering five devices at once), and since you’d be on a data cap anyway, it’s not like AT&T risks losing millions from five P2P servers being ran over one’s iPhone. Granted, it’s possible that some unicorn crafted this piece of paperwork to throw us all off, but we’ve reached out to AT&T and are awaiting comment. You know, just in case.

Update: Based on Apple’s iOS 4.3 page, only three WiFi devices are supported through the Personal Hotspot connection. If you’d like to tether five total devices, the other two will need to be over Bluetooth / USB. Don’t go blaming AT&T here — we’re guessing Verizon’s model will be set up the same way. Thanks, Christian!

WiFi-only Motorola Xoom appears at Sam’s Club, bearing $539 price?

You might have seen Motorola’s WiFi-only Xoom popping up at European e-tailers, but it’s reportedly flying the red, white and blue today, having materialized at Sam’s Club in the good ol’ USA. Droid-Life stumbled upon several snapshots of these Xoom Wi-Fi vouchers, with a $539 price tag hanging above their heads — plenty cheaper than a cellular Xoom, and also slightly more affordable than a similarly specced iPad 2. Of course, Sam’s Club deals in wholesale merchandise, and even should this price be accurate the tablet may not be widely available at the same rate, so don’t count out $599 as the Xoom Wi-Fi’s MSRP. Meanwhile, let us know if you manage to find and ring one up at the register, eh?

[Thanks, Michael]

iPad 2 arrives at the FCC

Right on cue, the three radio variants of the iPad 2 — that’s the WiFi A1395, GSM A1396, and CDMA A1397 — have arrived at the FCC’s labs for stringent testing. We’re sure Uncle Sam’s testers will stay on task checking up on RF interference and not just spend their time melting faces with Photo Booth, but we understand the temptation.

[Thanks, Laura]

Design project paints city’s WiFi networks with light

We’ve seen WiFi detectors used for various DIY projects before, but none quite like this rather ambitious project cooked up by Norwegian designers Timo Armall, Jørn Knutsen, and Einar Sneve Martinussen. They built a four-meter long WiFi-detecting rod that boasts 80 LED bulbs and carried it around various neighborhoods in Oslo, picking up signals of various strengths from nearby WiFi networks all the way. That’s only the half of it, though. The real kicker is that they also captured the whole thing with long-exposure photographs to effectively paint the “invisible terrain” of WiFi networks with light. Head on past the break for a video, and hit up the source links below for a closer look at the entire process.

[Thanks, Christer]

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.

Motorola prices WiFi-only Xoom at £450 in the UK (update: €700 in Germany with 3G)

Finally Motorola gives us a chance to say something positive about its pricing of the 10.1-inch, Tegra 2-powered Xoom tablet. UK electronics retailer PC World has just put up its Xoom pre-order page, which will surprise many waking Brits with an extremely reasonable £450 ($730) asking price. That’s £60 less than the direct competitor 32GB WiFi-only iPad — the Xoom only has one storage option of 32GB and the model listed here comes without 3G — and perhaps more importantly, is only £10 more than the 16GB version of Apple’s tablet. It’s common knowledge that to take on the iPad empire you’ll have to at the very least match its price, and Moto is doing even better than that in the UK. There’s only one worrying sign, we haven’t been able to place a Xoom into our shopping basket yet, as the “Pre-order today” button seems to be malfunctioning, but we’re guessing that’s a temporary glitch that will be fixed without the price shooting up skywards.

Update: T-Mobile Germany has also revealed its Xoom pricing, this time for the 3G model: €699.95. Distribution will begin at the end of April and T-Mo will have a three-month exclusive on the tablet in its native land. The pricing positions the Xoom a mere 95 Euro cents above the 32GB-equipped iPad WiFi + 3G, meaning that your choice will truly come down to preference and not economics. See T-Mobile’s full press release after the break.

Update 2: The PC World price and pre-order have been pulled. Gulp. Let’s hope they comes back unchanged.

[Thanks, John]

TI-Nspire graphing calcs get full color displays, 3D, WiFi, and new OS

It’s been a good year or so since the TI-Nspire line of graphing calculators got a refresh, but that was nothing compared to what the company’s planning for this year. Possibly responding to changing times (or the Casio Prizm), the new Nspire devices are getting a WiFi dongle for communication with TI-Navigator workstations, a 16-bit (320 x 240) full color display, and a number of new functions, including the ability to load images and analyze images for such things as curve fitting functions and regressions. Perhaps even more exciting, the new Nspire OS 3.0 features 3D functions — and, yes, the original grayscale TI-Nspire models will be able to upgrade to the new OS when it becomes available this spring. Tech Powered Math is reporting a mid-April release date, for an MSRP of $165. Totally psyched? We bet you are! See the PR after the break for more info.

Exclusive: Sony ‘S2’ dual-screen Android clamshell and 9.4-inch Windows 7 VAIO slider due this year

So, by now you’ve seen the PlayStation Certified Qriocity tablet known within Sony as the “S1.” But that’s not the only tablet the venerable Japanese company is preparing to launch in 2011. We’ve been told by a pair of highly trusted and proven sources that Sony is also working on two rather unconventional tablet form factors including a dual-screen Honeycomb clamshell and newfangled Windows 7 tablet slider.

First, let’s look at the clamshell model sporting a pair of 5.5-inch displays — a device first hinted at in a 2010 Sony patent application titled “Electronic Book with Enhanced Features.” However, unlike the patent’s blocky illustration, we’re told that Sony’s clamshell — known as the “S2” internally — more closely resembles an oval cylinder when closed as depicted in the illustration above. Spec-wise, we’re told that it will be very similar in performance to the S1 with a Tegra 2 SoC and WiFi + 3G radio on the inside and front- and rear-facing cameras on the outside. And like the S1 tablet, the S2 will be focused on delivering Qriocity media to the consumer. Sorry, no word on whether the S2 is PlayStation Certified. Obviously, the S2 won’t be running stock Honeycomb — instead, Sony is currently optimizing the Android OS to make the most of those two displays. One source reports having seen Gmail running on a demonstration prototype where the list of messages is displayed on one screen with the body of the selected message displayed on the other. Maps, we’re told, will display the map graphic on one display with the detailed turn-by-turn instructions or Streetview displayed on the other. Likewise, the S2 will display a video and picture navigation menu on one half of the clamshell with the selected content blown-up to fill the screen of the other. We’re also told that these apps will work in a variety of orientations. Sounds interesting, to say the least. Regrettably, our sources are less than enthusiastic. Click through to find out why.

‘Stanford gurus enable two-way radio communications. Over.’

Call it the holy grail of radio transmissions if you must, but even if you’re not about to toss that label on it, there’s no question that the work being done in Stanford‘s engineering labs could destroy quite a few preconceived notions about wireless interference. Demoed as a concept last year, a newfangled wireless technology developed in Palo Alto is proving that signals can indeed be sent and received at the same time. Outside of the cellular telephony world, this seemingly simple occurrence doesn’t really happen — typical wireless signals have to take turns when it comes to listening and transmitting. As an example, it’s impossible for a WiFi router to “shout” out signals while also being intelligent enough to quiet its own voice in order to hear “whispers” from a connected device. The breakthrough came when researchers found that radios could be tweaked to filter out the signal from its own transmitter, something that already happens within noise-canceling headphones. If this can be packaged into a commercially viable platform, it could instantly double the amount of information sent over existing networks, and on an even grander scale, it could allow airplanes to radio into control towers simultaneously (a feat that’s shockingly impossible with today’s physics bearing down). Head on past the break for a downright enlightening video on the matter.
