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.

Yesterday’s lab installment gave us an opportunity to pit the Lumia 920 against competing smartphones in a low-light capture scenario, but Nokia’s standard battery of tests is used to evaluate and improve far more than stills shooting. Several stops throughout the day brought us to a foam-filled sound chamber tasked with analyzing call quality in a variety of environments, a room with industrial freezers and ovens used to push the limits of operability, and a rig that can shoot with interchangeable sensors and apply image quality algorithms in real-time, without a handset in sight. Unfortunately, due to proprietary technologies and processes, we weren’t permitted to photograph these first facilities, though we did manage to snap away at two other stations — a platform that shifted up and down at adjustable speeds to test the Lumia 920’s optical image stabilization, and a machine that drops smartphones against a block of concrete, used to simulate that all-too-frequent occurrence of handsets plunging towards pavement.

We’ve seen plenty examples of the 920’s OIS capabilities this week, so we won’t go into much more detail on that front, but specialized (and pricey) equipment enables engineers to introduce consistent processes — this machine simulated hand shake at different speeds, and even with exaggerated movement, the benefits were clear. A separate building contained the drop test contraption, which releases devices from an adjustable height, letting them land directly on a block of polished concrete. We tested both the 808 PureView and a Samsung Galaxy S III in this manner (with roughly 100 Lumia prototypes currently available, Nokia wasn’t quite willing to risk sending one to its death). Both smartphones remained in perfect working order following the drop, so it’s likely that they’ll be able to handle a similar fall during regular use as well (company reps offered to test our iPhone 5, but we declined handing it over). That wraps up our week at Nokia’s facilities in Finland — there will be plenty more to explore once we have a Lumia sample in hand, but you’ll find the OIS test and concrete plunge videos ready right now, posted just after the break.

The new iPhones are here for AT&T, Verizon, and Sprint and at long last, they’ve got 4G LTE. So which iPhone 5 is fastest? And does it make any difference that it supports both 5GHz Wi-Fi in addition to 2.4GHz. There’s pretty definite winner, but more importantly a very clear loser. More »

Road safety continues to be a major concern for both researchers and car makers alike. Yesterday saw yet another real-world trial kicking off, this time on a much grander scale. A total of 3,000 vehicles in Ann Arbor, Michigan are taking part in a 12-month project run by the state’s Transportation Research Institute. The vehicles have Dedicated Short Range Communications and video recording facilities, which means the cars can communicate with each other, traffic signals, and share data to a central platform — which in turn issues warnings when high risk situations, or if traffic problems occur. Of course, this trial will also create a massive data set, which researchers will be able to plunder, and help the National Highway Traffic Safety Administration (NHTSA) better determine the viability of such systems. So while it’s unlikely to lead to self driving cars just yet, it’s a step in the right direction.

Ever wondered why those crazy fools at Facebook think it’s a good idea to meddle with the timeline, or how you chat? Well you can blame yourself. Probably. The social network’s Director of Engineering, Andrew “Boz” Bosworth, reveals all in a recent blog post. By first explaining that the site evolves in a two-step process, “technology pushes people to move forward and then people move past technology and it has to catch up,” we can start to understand why constant user testing of new, often multiple, solutions is required. Boz goes on to explain that by using select groups, or even nations, the efficacy new features can not only be quickly, and solidly determined, it can actually supplant the need for weeks of boardroom debate. He goes on to say that the odds are that everyone on Facebook has been part of a test at some point. Curious to know more about the process, or just feeling a little bit used? Head over to the source link for the full post / comment thread.
