When apps aren’t designed to work efficiently with the cellular network, performance suffers for the end user, batteries drain faster, and network resources are not well-utilized.
The issue has always been a lack of visibility into the complex interactions between apps and the lower-layer protocols normally hidden by APIs.
New technology created by AT&T researchers with colleagues from the University of Michigan is now making these interactions visible, and showing developers how simple design changes can result in energy-efficient apps that use less battery power and respond faster to user input. Read more
Internet traffic growth is slowing, but video is growing more than 80% annually. These findings and others were made by Alexandre Gerber and Robert Doverspike after analyzing Internet traffic over AT&T Networks. Their analysis, which has implications for efficient use of backbone capacity, is detailed in a paper presented at OFC/NFOEC.
The iTeX iPad app, from William Cheswick and available on iTunes, displays technical documents exactly as rendered by TeX. Land- scape and portrait formats are supported as are larger type sizes. Text is rendered as images, making iTeX language-independent.
Source code will soon be available from the iTeX webpage.
Some of the futuristic technologies featured in AT&T's Network of Possibilities ads are based on projects from AT&T Research.
One ad features AT&T's real-time speech translation and its AirGraffiti augmented-reality app (built to demonstrate network support for location-based services). Another ad shows Geocast for outdoor GeoGaming.
Lead Member of Technical Staff
Each year, the President of AT&T Labs awards the AT&T Fellow Honor to a few selected recipients.
One of three honorees this year, Mikkel Thorup is being honored "for outstanding innovation in algorithms, including advanced hashing and sampling techniques applied to AT&T's Internet traffic analysis and speech services."
Lead Member of Technical Staff
The AT&T Fellows Honor traces its tradition from Bell Labs and is awarded for extraordinary technical breadth and depth demonstrated over a career of achievement.
Theodore Johnson is being honored "for outstanding contributions in database and data stream processing systems."
Edward Amoroso, Senior VP and Chief Security Officer
A dinner to celebrate this year's recipients will be held March 30, attended by current Fellows and AT&T upper management, with a speech by CTO John Donovan.
Ed Amoroso is being honored "for a distinguished career in pioneering contributions and innovations in the architecture design and development of information security."
