coondoggie writes "What if your wireless communications just absolutely, positively have to be heard above the din of other users or in the face of massive interference? That is the question at the heart of a new $150,000 challenge that will be thrown down in January by the scientists at DARPA as the agency detailed its Spectrum Challenge — a competition that aims to find developers who can create software-defined radio protocols that best use communication channels in the presence of other users and interfering signals."
sfcrazy writes "KDE developers have succeeded in running the touch-optimized Plasma Active Linux Distribution on Nexus 7. Earlier Ubuntu developers managed to create a installer for Nexus 7, but those builds also showed that Unity, in its current form, is not ready for touch-based devices. KDE has an edge here as they have optimized versions for netbooks, desktops and touch-based devices so a user doesn't have to make any compromises as one has to do with other DEs or shells which are focusing more in touch-based devices only." Here are detailed instructions on how to install it.
Today Nokia announced an agreement with Research In Motion to resolve all patent legislation between the two. The companies have been fighting over patents for almost a decade, most recently over devices with wireless LAN capabilities. The terms of today's agreement were not disclosed but it involved a one-time payment from RIM as well as ongoing payments. This agreement comes shortly after RIM's announcement that it pulled in $9 million in profit last quarter, down 97% from the $265 million they earned in the same quarter the year before. The company has pinned its hopes on BlackBerry 10, scheduled to launch next month: "So this is RIM at the end of 2012: losing subscribers and revenue, facing significant opponents, but with more cash on hand and at least one long-running lawsuit settled. If nothing else, it means the way is clear for RIM to launch its Hail Mary pass: BlackBerry 10."
coondoggie writes "Boeing calls it Project SPUDS — or rather, Synthetic Personnel Using Dielectric Substitution — that is, using sacks of potatoes perched on aircraft seats to test the effectiveness of wireless signals in an airliner cabin. Boeing said it was researching an advanced way to test wireless signals in airplanes and needed a way to effectively simulate 200-300 people sitting in seats throughout the aircraft."
SternisheFan writes "PCMag's Angela Moscaritolo writes: 'Samsung is expected to account for 29 percent of worldwide cell phone shipments, up from 21 percent in 2011, when it nabbed the No. 2 spot in the market. Meanwhile, Nokia's share this year will drop from 30 percent to 24 percent this year. Nokia had held the top spot in the mobile phone market since 1998.'" Not just highest sales of smartphones, but of all cell phones.
An anonymous reader writes with this IDG News report: "Samsung dropped all claims pending in European courts in which it asserted patents that are essential for mobile communication devices to prevent the sales of Apple products in Europe. The injunction requests against Apple, which aimed to get courts to impose sales bans on infringing products, were withdrawn in the U.K., France, the Netherlands, Germany and Italy. Samsung only withdrew the injunctions requests — other litigation against Apple in Europe continues, Anne ter Braak, a spokeswoman for Samsung in the Netherlands, said in an email on Tuesday. While Samsung said it withdrew its claims in the interest of protecting consumer choice, it could have to do with a European antitrust investigation."
An anonymous reader writes "Ars summarizes a new report into the common practice of ISPs implementing data caps, ostensibly to keep their network traffic under control. The report found a much simpler reason: money. Quoting: 'The truly curious thing about the entire debate has been the way in which caps have mostly remained steady for years, even as the price of delivering data has plunged. For example, paying for transit capacity at a New York Internet exchange costs 50 percent less now than it did just one year ago, and many major ISPs aren't paying at all to exchange data thanks to peering. So why don't prices seem to fall? ... The authors of the new paper contend that all explanations are more or less hand-waving designed to disguise the fact that Internet providers are now raking in huge—in some cases, record—profit margins, without even the expense of building new networks. ...While Internet users have to endure a ceaseless litany of complaints about a "spectrum crunch" and an "exaflood" of data from which ISPs are suffering, most wireline ISPs are actually investing less money in their network as a percentage of revenue, and wireless operators like AT&T and Verizon are seeing huge growth in their average revenue per user numbers after phasing out unlimited data plans—which means money out of your pocket. In the view of the New America authors, this revenue growth is precisely the point of data caps.'"
MrSeb writes "DARPA has begun development of a wireless communications link that is capable of 100 gigabits per second over a range of 200 kilometers (124mi). Officially dubbed '100 Gb/s RF Backbone' (or 100G for short), the program will provide the U.S. military with networks that are around 50 times faster than its current wireless links. In essence, DARPA wants to give deployed soldiers the same kind of connectivity as a high-bandwidth, low-latency fiber-optic network. In the case of Afghanistan, for example, the U.S. might have a high-speed fiber link to Turkey — but the remaining 1,000 miles to Afghanistan most likely consists of low-bandwidth, high-latency links. It's difficult (and potentially insecure) to control UAVs or send/receive intelligence over these networks, and so the U.S. military instead builds its own wireless network using Common Data Link. CDL maxes out at around 250Mbps, so 100Gbps would be quite a speed boost. DARPA clearly states that the 100G program is for US military use — but it's hard to ignore the repercussions it might have on commercial networks, too. 100Gbps wireless backhaul links between cell towers, rather than costly and cumbersome fiber links, would make it much easier and cheaper to roll out additional mobile coverage. Likewise, 100Gbps wireless links might be the ideal way to provide backhaul links to rural communities that are still stuck with dial-up internet access. Who knows, we might even one day have 100Gbps wireless links to our ISP."
hugheseyau writes "Dell vice chairman Jeff Clarke made a less than shocking announcement at this year's Dell World Conference in Austin. The company is officially giving up on Android phones and tablets. ... So if Dell is giving up on Android, what comes next? The company claims it's doubling down on Windows 8, and the enterprise market."

An anonymous reader writes "Germany has pretty much become the new Eastern District of Texas, the world's most popular patent battleground. After Apple, Samsung and Motorola, the Chinese are now going to Germany as well to sort out their domestic patent squabbles. Huawei and ZTE, arguably the People's Republic's leading wireless tech companies, started suing each other in April last year. On Friday the Mannheim Regional Court held a Huawei vs. ZTE hearing, reports a local patent watcher. Huawei says ZTE infringes a 4G/LTE handover patent and wants its rival's base stations and USB modem sticks banned in Germany. More clashes between the two are coming up in the same court and in other places in Europe, including France."
