Bell Labs’ lensless camera takes photos with a tiny amount of data
Although there have been attempts at lensless cameras before, few of them would replace our point-and-shoots when they're frequently expensive, or capture photos outside of the visible light spectrum. We shouldn't have either of those problems with Bell Labs' new prototype. The experiment uses an LCD as a grid of apertures that filter the light reaching a sensor. As that sensor can piece together an image simply by grabbing random aperture samples and correlating the data, it only needs a sliver of the usual information to produce a usable shot. The lens-free, mostly off-the-shelf approach could lower the costs of both the sensor and the overall camera, but it could also lead to simpler comparison tools: the correlation makes it easier to tell if an object is missing, for example. Bell Labs hasn't talked about any production plans, but we have a hunch that Alcatel-Lucent would rather not let its research wing's technology go to waste.

Bell Labs doubles beams in fiber optic lines to reach 400Gbps on a global scale
It's comparatively easy to run fiber optic lines at high speeds; it's another matter to sustain that pace between continents. Alcatel-Lucent's Bell Labs has found a way to go that extreme distance by relying on the basic concept behind noise-cancelling headphones. When the researchers send data across two light beams in opposing phases, they can superimpose the signals and neutralize the distortion that would normally occur at long ranges. Such clean output lets Bell Labs ramp up the signal strength and maintain high speeds across whole oceans: its test pushed 400Gbps through 7,954 miles of fiber. There's no word on how soon we'll see twin-light technique put into practice, although we suspect that a networking giant like Alcatel-Lucent wants the extra bandwidth as quickly as possible.

Alcatel-Lucent’s latest lightRadio development aims to spread TD-LTE across China
We've yet to hear much about Alcatel-Lucent's lightRadio since it's original introduction in early 2011, but here in Barcelona, the outfit has announced (in cooperation with China Mobile, no less) that its latest innovation could help spread the wondrous waves of TD-LTE across China. Available now for large-scale commercial deployment in China Mobile's first trial TD-LTE network, which spans 13 cities in China, lightRadio Metro Radio will bring legitimate 4G services to residents in densely populated areas of Shanghai, Nanjing and Qingdao.
China Mobile itself has over 722 million subscribers, and a huge swath of those are no doubt clamoring for faster transmission speeds. In China, lightRadio Metro Radio will be deployed in bustling indoor and outdoor locations, such as shopping malls and stadiums, but there's no word on when the masses might expect this stuff to launch in earnest. Here's hoping for a speedy trial, eh?
