Green, Soft, and Rethink Shannon

The rapid adoption of Smart Phones has triggered an explosive growth of mobile Internet applications. China Mobile has observed 81 times traffic growth over past 5 years, and it has been a common consensus that there will be another 1000x traffic load increase by year 2020. Unfortunately, the ARPU growth curve is believed to be much flatter. As the world largest mobile service provider, China Mobile is facing a big challenge to figure out a technical road map to increase its network capacity dramatically while keep the TCO at a reasonable level to maintain its viability. To this end, we envision increasing importance of making our network “green & soft”. The extension of classic Shannon theory from scalar domain to vector domain 20 years ago gave the birth of MIMO system, and has been supporting the sustainable development of wireless system all long. How will Shannon theory perform in new “green & soft” era? Is it out-of-date or reborn as a new “the one”? This presentation will share our vision and staged R&D effort marching toward “green & soft”.

Worldwide electricity consumption of ICT: figures and trends

ICT devices and services are penetrating more and more in all aspects of human life. Following an increased worldwide focus on the environmental impacts of energy consumption in general, there is also a growing attention to the electricity consumption associated with ICT equipment. This keynote speech will present an extensive study on the worldwide ICT electricity consumption in the use phase, ranging from 2007 to 2012. Three main ICT categories will be elaborated in more detail: communication networks, personal computers, and data centers. Our estimates show that the yearly growth of all three individual ICT categories (10%, 5%, and 4% respectively) is higher than the growth of worldwide human electricity consumption in the same time frame (3%). When we include all ICT equipment, its use phase represents about 9% of the global electricity consumption today. This percentage is expected to grow further in the years to come. These numbers clearly indicate the need and urgency for further research and actions to improve the energy efficiency of future ICT devices and solutions. The talk will present some promising research directions and future trends.

Dr. Thierry E. Klein
Head of Green Research,

GreenTouch Consortium: Overview, Vision and Recent Results of Green Meter Research Study

With the continued exponential growth of applications, services, devices and machines all being connected to the network, the total Internet traffic in the next decade is expected to grow to a level that is 30 to 100 times that of current levels. One of the challenges for next-generation networks is the ability to support the predicted traffic in a sustainable and economically viable way. In addition to the resulting increased energy consumption, the rising energy costs, the environmental impact of networks, and more so cially conscious consumers and service providers demand that our future communication and data networks are greener and more sustainable. During this  presentation, Thierry will review some of the current trends in communication and data networks and discuss the latest research to improve energy efficiency and reduce power consumption in mobile, wireline access, packet data and optical networks. He will also provide an overview and a status update of the GreenTouch consortium, an industry-wide initiative founded under the leadership of Bell Labs with the mission to deliver architectures, solutions and specifications, and to demonstrate key technologies, to improve the network energy efficiency by a factor 1000 compared to 2010 levels. In particular he will discuss the results of the Green Meter research study and the recent GreenTouch announcement that it is possible to reduce the net energy consumption in communication networks by up to 90% by 2020.

If telecommunication is such a good substitute for travel, why does congestion continue to get worse?

Saving travel has always been a motivation for the creation and use of information and communication technologies. So with the ongoing spread of ever-improving technologies, why do travel and congestion continue to increase? Twelve reasons for this paradoxical result are presented, as well as four reasons why some substitution can be expected.
