A Call for More Energy-Efficient Apps

by: Staff with Alexandre Gerber, Subhabrata Sen, Oliver Spatscheck, April 7, 2011

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 

Understanding Internet Traffic


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.

Free iPad app for displaying TeX documents


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.  

AT&T Research projects featured in AT&T ads


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.
