The seventh in a series of ITU-T Technology Watch Briefing Reports covers next generation networks (NGN) and energy efficiency.
The report examines the relationship between climate change and NGN by analyzing energy efficiency and applications.
NGNs are seen by many as the new network architecture that will unify today’s fixed, mobile and broadcast networks. This innovative technology is expected to bring about greater energy efficiency than legacy networks by, for example, reducing the number of switching centres and increased temperature tolerance within those centres. NGNs are expected by some commentators to reduce energy consumption by 40 per cent compared to today’s public switched telephone network (PSTN).
This report presents an overview of the main characteristics of NGN and looks at how NGN can minimize the power consumption of the network, transmission and end-user equipment and in data centres. It examines the energy savings that can be indirectly obtained from greater NGN usage, such as remote collaboration and ITU-T standardization work on NGN and climate change.
