Bell Labs and net mobile Improve In-Car Streaming Video QoE

Alcatel-Lucent announced that "Bell Labs and net mobile AG (net-m) have reduced the probability of poor video streaming quality on the move with a new technology that can deliver a six-fold improvement over today’s streaming levels - without consuming any extra network capacity.

The new technology – Context-Aware Video Streaming - is based on Bell Labs’ Context-Aware Radio Access (CARA) solution. This makes smart use of location-based information, including road and network coverage maps and radio performance data, to deliver algorithms that predict upcoming network performance. Based on this prediction, more seconds of the video are downloaded to the consumer’s device in areas of good coverage before the vehicle enters a poor coverage area. This results in a dramatic reduction in video stalling and the quality of experience is greatly improved for the consumer.

The gains in quality were measured during test drives across Düsseldorf in Germany over a conventional mobile network. The routes consisted of highways, tunnels and other typical areas for consumers travelling through the city in a car or public transport vehicle. A video shows the difference in quality of video streaming on-the-road between two devices, one with context-aware technology and one without"

  1. You’re so cool! I don’t suppose I’ve read anything like this before. So nice to find somebody with some original thoughts on this subject. Really! Thank you for starting this up. This website is something that is needed on the used car exporter, someone with a little originality. Useful job for bringing something new to the internet!
