suraj.sun writes to mention that Long Term Evolution (LTE) networks may have just gotten a boost over WiMax in the battle for wireless broadband dominance. A group of telecom companies has created the "One Voice" initiative, designed to promote a standard that will provide interoperability for broadband voice and SMS. "LTE has been fine at supporting data, which uses IP-based packet switching. But it's faced challenges trying to incorporate traditional circuit-based switching voice and SMS services onto IP-based networks. One Voice is the group's attempt to resolve that issue. The new specification will use existing functionality known as IP Multimedia Subsystem (IMS), which already defines how to provide data, voice, and other content over an IP-based network. IMS was established by the 3rd Generation Partnership Project (3GPP), a group comprised of telecom industry associations trying to set standards for 3G mobile networks."

alphadogg writes "AT&T has created different mobile calling models for every major city in America as it tries to improve a network that has come under fire for poor performance as the data-friendly iPhone has proliferated, an executive said Thursday. Other carriers just use one nationwide calling model to plan for all cities, claimed CTO John Donovan, speaking at the Open Mobile Summit conference in San Francisco. The nation's second-largest mobile operator has had a hard time planning for bandwidth needs in the rapidly changing mobile world, Donovan said. AT&T has seen rapidly growing mobile data usage — and much criticism over its 3G coverage — as the exclusive iPhone carrier in the US. 'If a network is not fully loaded, it's hard to know exactly how much demand is out there,' Donovan said. 'You put all you can in the ground, and they eat it all up, and then you put more in there, and they eat it all up.'" The story notes that mobile data at AT&T has grown 4,932% over the last 3 years.

Several readers sent in an update on DTN, the interplanetary Internet protocol that Vint Cerf has been working on for many years (and we have been discussing for nearly as long). The news now is that Cerf has added a DTN stack to the open source Android code, seeing uses in mobile applications for a protocol that does not assume a continuous connection.

TechRev_AL writes "A team from the University of Washington has attached an RFID chip capable of sensing neural activity to a live moth, to pick up the spikes that occur as it beats its wings. Most neural implants are still relatively bulky, but the Washington researchers wanted to show the components in an RFID could be adapted for the same purpose. The NeuralWISP chip is a collection of low-power components such as a specialized signal amplifier, on a circuit board just over two centimeters long. The circuitry converts usable power from the reader — roughly 430 microwatts — to a voltage that can turn on a microcontroller. The sensor is also configured to 'wake up' only when a neuron fires. The ultimate goal is to create more compact, wirelessly-powered brain and nervous system implants for people."

Riskable writes "Remember that $200,000 Contest For a Better Open-WRT Wireless Router GUI? Today Ubiquiti posted the winning entries to their support wiki. The grand prize was a tie between PyCI (written by yours truly) and NETSHe with OpenNET as the runner up. Source code and firmware images for each entry are available for download on their respective wiki pages. I'll be setting up a project page for PyCI (and l2sh) soon to make it a participatory open source product. Even if you don't have a RouterStation, or don't care about OpenWRT, there are numerous Python modules and tools inside of PyCI that could prove useful to other open source projects (e.g. iptables.py can read/interpret over 400 permutations of the iptables command). I'll also be checking the comments if anyone has any questions for me about PyCI or the contest in general. BTW: I'd like to thank all the commenters in the original article that insinuated that the technical requirements were impossible and/or that making a GUI to configure such complex things is a waste of time. I read every one and I wouldn't have made it such an obsession otherwise!"

cananian writes "The webbook company of Gnome's own Havoc Pennington (with a healthy dose of ex-Nokia and ex-OLPC engineers) finally shed its secrecy today, with a new web site and an article in the WSJ. Technical specs on the hardware were found by Engadget last week, and now comes a bit more information on the software behind the UI. Most of the client software is written in JavaScript with GTK/Clutter bindings, and the UI has some superficial similarities to Pentagram's designs for OLPC's Sugar."

MahlonS writes "AP is reporting on a suit filed in Northern Georgia in which AT&T claims that Verizon's 'There's a Map for That' ads are misleading and amount to deceptive trade practices. Verizon had already agreed to modify their original ad to include a tag line that voice and data services are available outside 3G coverage areas." What's interesting is that on some level, this is actually a lawsuit over data visualization.

An anonymous reader writes with this excerpt from Engadget: "It wasn't all that long ago that Microsoft was talking up the Virtual WiFi feature developed by Microsoft Research and set for inclusion in Windows 7, but something got lost along the road to release day, and the functionality never officially made it into the OS. As you might expect with anything as big and complicated as an operating system though, some of that code did make it into the final release, and there was apparently enough of it for the folks at Nomadio to exploit into a full fledged feature. That's now become Connectify, a free application from the company that effectively turns any Windows 7 computer into a virtual WiFi hotspot — letting you, for instance, wirelessly tether a number of devices to your laptop at location where only an Ethernet jack is available, or even tether a number of laptops together at a coffee shop that charges for WiFi."

An anonymous reader writes "Trusted Reviews has put the new Dell XFR rugged laptop through the grinder and it hasn't fared as well as expected. Considering that these guys drove a car over a Panasonic Toughbook, they went pretty easy on the Dell, but it still couldn't take the punishment. It looks like Dell still has a way to go to steal the ball from Panasonic when it comes to all terrain computing."

waderoush writes "In May 2008, Nicholas Negroponte, chairman of the One Laptop Per Child Foundation, unveiled an e-book like design for the second-generation XO Laptop, consisting of a pair of facing touchscreens. In a new e-mail interview, Negroponte says that design has been thrown out, and that instead the foundation is working on version '1.75' of the existing green-and-white laptop with a more powerful processor, as well as a '3.0' version that would look 'more like a sheet of paper.' Negroponte also addressed a range of other questions about the OLPC project, including the significance of the project to make 1.6 million e-books readable on the XO laptop and the organization's push to reach more children in Latin America, Africa, Afghanistan, and Pakistan."
