Amazon said to have tested technology for its own wireless network

Amazon may not be happy with just piggybacking on other wireless carrier’s signals for Whispernet-style offerings, as Bloomberg has heard it’s trying out technology that would let it create its own wireless network. The technology used in the tests is from Globalstar, which is seeking to convert its spectrum — intended for use by satellite-connected devices like the Global Phone pictured above — for strictly ground-based use. The report points out a letter from Globalstar technical adviser Jarvinian to the FCC indicating it was helping a “major technology company” assess the performance benefits available earlier this year. The usual people with knowledge of the situation have filled in the blanks, however whether the tests are continuing or if Amazon will ever make real use of it is unknown. If things do move forward Amazon would hardly be alone in its efforts with Dish Network’s similar push to use spectrum it owns for LTE. If Globalstar really can do LTE / public WiFi better we’re ready to hear about it, although hopefully it will connect to more hardware than just some future Kindle Fire 4.

Real Life Death Star? No, It’s How GE Tests Jet Engines

To ensure the safety of America’s 730 million annual air travelers, all new jet engines must undergo arduous FAA safety testing—including a grueling series of static ground tests subjecting them to everything from gale force winds to simulated bird strikes. But how does one reproduce the identical test conditions needed for accurate performance measurements? You use a 32-foot wide wind baffle, of course. More »

AMD FX-8350 review roundup: enthusiasts still won’t be totally enthused

DNP AMD's refreshed FX 'Vishera' processor benchmarked, enthusiasts not enthused

Now that AMD’s fresh new FX processors based on the Piledriver architecture are out in the wild, the specialist hardware sites have seen fit to benchmark the top-lining FX-8350. Overall, the group feels that AMD has at least closed the gap a bit on Intel’s Core juggernaut with a much better FX offering this time around, but overall the desktop CPU landscape remains unchanged — with Intel still firmly at the top of the heap. Compared to its last-gen Bulldozer chips, “in every way, today’s FX-8350 is better,” according to Tom’s Hardware: cheaper, up to 15 percent faster and more energy efficient. Still, while the new CPUs represent AMD’s desktop high-end, they only stack up against Intel’s mid-range Core i5 family, and even against that line-up they only edge ahead in heavily threaded testing. But if you “look beyond those specific (multithreaded) applications, Intel can pull away with a significant lead” due to its superior design, says Anantech. As for power consumption, unfortunately “the FX-8350 isn’t even the same class of product as the Ivy Bridge Core i5 processors on this front,” claims The Tech Report.

Despite all that, Hot Hardware still sees several niches that AMD could fill with the new chips, as they’ll provide “an easy upgrade path for existing AMD owners and more flexibility for overclocking, due to its unlocked multipliers.” That means if you already have a Socket-AM3+ motherboard, you’ll be able to do a cheap upgrade by swapping in the new CPU, and punching up the clock cycles might close the performance gap enjoyed by the Core i5. Finally, AMD also saw fit to bring the new chip in at a “very attractive” $195 by Hexus‘ reckoning, a much lower price than an earlier leak suggested. Despite that, however, the site says that AMD’s flagship FX processor still “cannot tick as many desirable checkboxes as the competing Intel Core i5 chips.” Feel free to scope all the sources below to make your own conclusions.

Colombia to start testing 700MHz LTE, joins a Latin American trend in 4G

Colombia to start testing 700MHz LTE, joins a Latin American trend in 4G

Those in the US can brag about having the range, indoor friendliness and other advantages of 700MHz LTE, but few other countries have that edge so far: Latin Americans who have any LTE at all usually have to contend with less tolerant 2.6GHz bands. Colombia isn’t happy with that state of affairs, and its National Spectrum Agency is spearheading a rapidly growing 4G movement in the region by testing 700MHz LTE between the fall and winter. Its strategy echoes proposals from Brazil and Mexico that will use the Asia-Pacific Telecommunity band plan, providing more efficient airwaves as well as wider device and network coverage. It will take beyond early 2013 before Colombia and its neighbors are actively using 700MHz bands — the digital TV transition is one of the bigger obstacles — but there’s desires for a fast-track spectrum handout that could bring blazing speeds to Bogota before too long.
