Towards greener Cable with adaptive powering

Energy consumption in broadband networks is significant and so is their environmental impact. According to some studies, the carbon footprint of the Internet already exceeds that of global air travel [1], which poses a challenge to the traditionally energy-dependent cable industry. Despite the accelerating environmental concerns, operators need to build more network capacity to maintain high availability of broadband services and keep pace with the increasing online activity. New solutions are needed to manage the growth while taking the environmental issues into serious consideration.
