How Mobile Phones Work Behind the Scenes 220

adamengst writes "We seldom think about how our mobile phones actually work, but in this TidBITS article, Rich Mogull pulls back the covers and peels away the jargon to explain why text messages work when voice calls are dropped, why your battery lasts longer in some places than in others, why you're not allowed to use phones on airplanes, why you can be notified of a voicemail message when your phone never rang, and more."

Hands-On With the PSP-3000 41

Eurogamer got a chance to take a look at Sony's latest hardware revision for the PSP. Their overall impression of the new model is positive, finding that a redesigned screen offers noticeably better graphics and higher brightness without affecting battery life. They also say the button pads may be slightly different, and the unit comes with useful firmware upgrades. "Elsewhere, our side-by-side comparison of the current PSP/PSP-2000 firmware, 4.05, and the new 4.20 firmware on the PSP-3000 reveals a 'USB Auto-Connect' option, which promises to automatically switch the handheld to USB mode when a cable is connected. It will do this from anywhere on the XMB, but it won't interrupt gameplay. ... The new-model PSP also allows you to play games on a TV by hooking it up with a special adapter (sold separately) and a composite cable, whereas the old one would only allow composite cables to display video, with gaming reserved for component output."

Netbook Return Rates Much Higher For Linux Than Windows 663

ivoras writes "An interview with MSI's director of US Sales, Andy Tung, contains this interesting snippet: "We have done a lot of studies on the return rates and haven't really talked about it much until now. Our internal research has shown that the return of netbooks is higher than regular notebooks, but the main cause of that is Linux. People would love to pay $299 or $399 but they don't know what they get until they open the box. They start playing around with Linux and start realizing that it's not what they are used to. They don't want to spend time to learn it so they bring it back to the store. The return rate is at least four times higher for Linux netbooks than Windows XP netbooks.'"

"Netbooks" Move Up In Notebook Rankings 139

Ian Lamont writes "For the first time, a list of popular notebook reviews shows three 'netbooks' in the top 10. The netbooks use Intel's Atom processor. Notebookreview.com's editor says there has never been more than one netbook in its monthly ratings. The reason for the netbooks' sudden popularity no doubt relates to the price and basic functionality, but there's a catch. Despite calling Atom a 'high-performance' chip, Intel cautions people not to confuse netbooks with notebooks, as netbooks will be unable to take on video editing or other processor-intensive tasks. This leads to the question of how netbooks will be able to handle demanding Web apps — or whether Web apps will have to be slimmed down to accommodate millions of netbook owners."

Amazon Kindle 2 Leaked, Sony Reader To Get Touch Screen 143

suraj.sun writes with news that the e-book reader market is getting more competitive. The Boy Genius Report got its hands on pictures of the Kindle 2, successor to Amazon's first e-book gadget. The new version is a bit bigger, with edges that are less awkward, and it has a revamped key layout. On the same day these pictures were found, Sony announced that a new model of its Reader would be getting a touchscreen, allowing users to "turn the page by swiping their finger across the screen" and "annotate text using a touchscreen keyboard." The advances for each gadget may help them regain market share against the iPhone, which, according to Forbes, has eclipsed both in popularity as a reading device. Hopefully the competition for sales and the work being done by the OLPC Project will help to drop prices as well.

Motorola To Hire 300 Android Developers 88

ruphus13 writes "Google's Android is starting to see more industry support. Motorola recently announced plans, despite hardships within the company, to hire 300 Android developers. Quoting: 'A quick search of Motorola's job openings suggests that, indeed, Android is set to become a permanent fixture at Motorola, which has long built Linux-based phones but hitherto used MontaVista's Mobilinux. The goal? Move from an internal development pool of 50 Android-savvy developers to 350. Motorola, recognizing that most developers won't have deep experience with Google Android, is looking for a somewhat general skillset ... Java and Google Android programming experience is listed as 'highly desirable,' but not required.'" T-Mobile has already made plans to use Android as well. Xconomy has a related interview with a member of the MIT team that won a $275,000 prize in the Android Developer Challenge by creating an application to automatically modify a phone's settings depending on its location, which they say "wouldn't even be possible on an iPhone." We've previously discussed the Challenge itself and some of the other winning apps.

Replacing Fiber With 10 Gigabit/Second Wireless 107

Chicken_dinner writes "Engineers at Battelle have come up with a way to send data through the air at 10 Gigabits per second using point-to-point millimeter-wave technology. They used standard optical networking equipment and essentially combined two lower bandwidth signals to produce a 10Gb signal from the interference. They say the technology could replace fiber optics around large campuses or companies or even deliver high-bandwidth streaming within the home."

Linux Rescues Battery Life On Vista Notebooks From Dell 200

nerdyH writes "Dell is preparing to ship two enterprise-oriented Windows Vista notebooks with an interesting feature — a built-in TI OMAP (smartphone) processor that can power instantly into Linux. The 'Latitude ON' feature is said to offer 'multi-day' battery life, while letting users access email, the web, contacts, calendar, and so on, using the notebook's full-size screen and keyboard. I wonder if someday we'll just be able to plug our phones into our laptops, switching to the phone's processor when we need to save battery life? Or, maybe x86 will just get a lot more power-efficient. Speaking at MontaVista's Vision event today, OLPC spokesperson and longtime kernel hacker Deepak Saxena said the project is aiming for 10-20 hours of battery life during active use, on existing hardware (AMD Geode LX800 clocked at 500MHz, with 1GB of Flash and 256MB of RAM)."

Researchers Re-Examine Second Law of Thermodynamics 125

Many readers have written to tell us that researchers are examining the possibility of using Brownian ratchets to help combat the problem of heat dissipation in miniaturized electronics. "Currently, devices are engineered to operate near thermal equilibrium, in accordance with the Second Law of Thermodynamics which states that heat tends to transfer from a hotter unit to a cooler one. However, using the concept of Brownian ratchets, which are systems that convert non-equilibrium energy to do useful work, the researchers hope to allow computers to operate at low power levels, and harness power dissipated by other functions. 'The main quest we have is to see if by departing from near-equilibrium operation, we can perform computation more efficiently,' Ghosh told iTnews. 'We aren't breaking the Second Law — that's not what we are claiming,' he said. 'We are simply re-examining its implications, as much of the established understanding of power dissipation is based on near-equilibrium operation.'"

Researchers Identify Wi-Fi Dead Zones Cheaply 37

schliz writes "A new technique developed by HP Labs and Rice University could lower the cost of identifying 'dead zones' in large wireless networks. The technique '[combines] wireless signal models with publicly-available information about basic topography, street locations, and land use.' This enables Wi-Fi architects to test and refine their layouts cheaply before a network is deployed by focusing measurement efforts on areas that potentially could be dead zones. The technique requires only about one-fifth as many measurements as a grid sampling strategy."

Managing Personal Electronics and Software In the Workplace 387

darien writes "Last night Symantec hosted a round-table discussion on the topic of consumer devices in the workplace. John Brigden, Symantec's senior VP for EMEA, pointed out that regardless of the policies businesses may lay down, individuals will always try to use their favorite gadgets and websites at work. Reminds me of when I worked in IT support: no matter how many times we told users they weren't allowed to install ICQ, or to connect their personal laptops to the corporate network, they insisted on doing it. Frequently they even asked us to help them do it."

WiMax Is Finally Coming — Here's How It Performs 112

GMGruman writes "Carriers have promised WiMax networks for years. But will they deliver the goods, or be slow like many early 3G networks or patchy in coverage like the metro Wi-Fi attempts in most cities? This hands-on review looks at a nearly-WiMax deployment (technically, OFDM) in Reno, testing its speeds and reach, as a measure of what Sprint and Clearwire will deliver in their joint WiMax rollouts starting next month. The good news is that this time, the carrier promises look to be delivered on."

"Pull" Barcode Scanning Could Be Android's Killer App 296

Seor Jojoba writes "The release of T-Mobile's G1 Smartphone is shifting focus away from push-based barcode scanning, where embedded URLs send you to locations of a vendor's choosing. There is now more interest in pull-scanning, where product information is retrieved from user-specified sources. It may be that QR-Codes and other 2D barcodes will have their thunder stolen by 1970s-era linear barcodes. On the iPhone, scanning a 1D barcode is slow and unreliable. But the G1's improved optics and Android's improved access to image scans has made 1D scanning quick and useful, opening the gateway for killer apps that help people make spending decisions."

Designing The Ultimate Netbook 354

Harden writes "TrustedReviews has an interesting take on what the 'Ultimate Netbook' ought to be. From the article: 'How to solve a problem like the netbook? To my mind, despite nearly every manufacturer taking a stab at the thing, none has yet quite distilled my idea of what the Ultimate Netbook would be. This is partly because, until recently, not everyone had a clear understanding of what a netbook was meant to do, but also because manufacturers have all been far too busy jostling for market share to put a lot of thought into the finer details.' What would your Ultimate Netbook include?"

Google Reveals Wireless Vision — Open Networks 90

Anti-Globalism writes with this excerpt from CNet: "Google's vision of tomorrow's wireless network is in stark contrast to how wireless operators do business today, setting the two sides on a possible collision course. Earlier this week, the search giant filed a patent application with the US Patent Office describing its vision of an open wireless network where smartphones aren't tied to any single cell phone network. In Google's open wireless world, phones and other wireless devices would search for the strongest, fastest connection at the most competitive price. Essentially, wireless operators' networks would be reduced to 'dumb pipes.'" The full patent application is available as well. Google founder Larry Page recently asked the FCC to free up portions of the broadcast spectrum for this purpose.
