Demonstrate Key Technologies to Increase Network Energy Efficiency by a Factor 1000 Compared to 2010

GreenTouch™ (www.greentouch.org)

• Bell Labs Initiated Global Research Consortium representing

industry, government and academic organizations

• Launched in May 2010 with focus on energy efficiency,

sustainability and growth

• Holistic and ambitious goal of 1000x
• 53 member organizations with 350+ leading scientists
• New innovation model for sustainability
• Recognized by the World Economic Forum as an industry-led best

practice toward sustainability

• Leading Green ICT: cooperation with other NGOs such as GeS

I, ITU-T , GreenGrid, Carbon Trust, ITRS

Large Scale Antenna System

• Use many more service-antennas than terminals

with data beams directed towards the terminals

• Increased spectral efficiency (bits/ s/ Hz) and

radiated energy efficiency (bits/ Joule)

• Technological advantages:
• Only needs cheap, single-antenna terminals
• All complexity at the base station
• Expensive power amplifier amplifiers replaced by many

low-power low-precision units

• Important to consider total system energy

consumption and energy efficiency:

• Radiated power
• LS

AS-critical computing processing power

• Internal per-antenna power consumption

(RF chains, analog blocks, A/ D)

Signaling Data sleep sleep sleep sleep sleep

Separate

Beyond “cellular” coverage with data capacity on demand

Opportunities for sustainability:

• System designed for energy efficiency
• Separate capacity from coverage
• Optimise signalling transmission
• Lean access to system
• Cope with massive amount of low

data rate services Challenges:

• New system architecture
• Re-invent mobility management
• Agile management, context aware,

network with memory

• Hardware for fast reconfiguration
