New research brings better wireless to remote locations, 80 percent faster GoT downloads
Not getting the bandwidth you need, Heidi? Then maybe the folks at North Carolina State University can help. They've figured out a way to boost multi-hop networks, where data is forwarded across two or more nodes (hops) in order to reach far-flung users. Networks like this can often get bogged down by interference between neighboring nodes. But by using algorithms to automatically modulate the power of each link, the NC State scientists have managed to jump efficiency by up to 80 percent. This has the effect of not only increasing speed, but also saving juice if the systems are battery powered -- like those used by the US Army, which sponsored the research. After all, just because you're away from the throne doesn't mean you have to be out of the game.
Sony unveils 15.5-inch VAIO NW with BD-ROM and $880 price tag, we go hands-on
Sony announced today a new entry into its VAIO series, the NW, complete with a Blu-ray drive and what they're hoping is an aggressive pricing point. It's packing a 15.5-inch WXGA display with XBRITE, 2GHz Intel Core 2 Duo P7350, ATI Mobility Radeon HD4570 with 512MB VRAM, a 4x BD-ROM drive, 4GB of DDR2 RAM, webcam, 802.11a/b/g/n, a 400GB HDD, and a Li-ion battery that's at best 5.5 hours in large capacity and at worst 1.5 hours with the standard-sized version. Port-wise, we've got VGA and HDMI output and Memory Stick Pro, ExpressCard, and SD card slots. We got a chance to get some hands-on time with the portable, and we gotta say, it's a pretty impressive little number. It's not the most slender 15-incher, but at six pounds, it's lighter than we expected. The chiclet keys -- dubbed "isolated keyboard" by Sony PR -- are comfortable to use, as is the textured trackpad. Body and hinge felt sturdy, with an intentionally rugged and stylistic feel to it, and as one rep was excited to show, the metallic "Vaio" logo on the back makes a great reflection in the sun. From what we saw, Blu-ray playback was smooth, but we did notice horizontal viewing angles weren't the best. We'll reserve judgment when we get some play time with the unit and see how hard we can push the software, but for now we're pretty happy with what we've seen. Starting price isn't too shabby, at $880 equipped with the BD-ROM and $800 without, and it comes in three colors: white, grey, and dark brown. Striking your fancy? Look for it to ship out pretty quickly, as in some time next month.
