GREEN RADIO NETWORK ARCHITECTURE APPROACHES

Base Station Hardware • Ultra Low-Power Base-Station on a Chip • Photonic Enablers for RF Systems • High Efficiency RF-Power Amplifiers • Renewable Energy Powering • New Architectures such as lightRadio™

Green Air Interface • Large Scale Antenna Systems • Very High Bandwidth

Rethink entire wireless access for energy efficiency

Network Architecture & Mgmt • Dynamic Management for Energy

Efficiency • Small Cells, Relays and Repeaters • New BS Architecture – Cloud Computing

for Signal Processing


13

WIRELESS PROJECTS PORTFOLIO

•Large Scale MIMO Demo (Feb. 1st 2011 in London)

•Large scale antenna systems (LSA) • Massive MIMO • Distributed Antenna Systems

•Green transmission technologies (GTT) • Very high bandwidth wireless systems • Tradeoff btw. energy efficiency and spectrum efficiency,

bandwidth, service delay

•Beyond cellular green mobile networks / architectures (BCG) • Green Network Management / Intelligent Power

Management • Independent network configuration for data and signaling


14 14

Concept: Ultra high energy-efficiency wireless through

selective beam-forming, in highly cluttered environments,

using base-stations with hundreds of antenna

Expectation: ~100x improvement in energy efficiency in

highly mobile, multi-user systems

Challenges: • Base-station design • Acquiring CSI, calibration, … • Total power reduction • New standards

First Year Demo


A Network That Behaves Like A Full Mesh

Macro Base Station

Small Base Stations

• In real networks (mesh in the core, tree at the edges), dynamically allocate/switch a virtual fiber link between the two end-points of a transaction, with minimum routing

• Bring antenna as close to user as economically feasible; design for high antenna gains; opportunistic use of high BW

• Service aware and adaptive network with ultra-low energy information and content delivery

• Low Power, ultra-high energy efficiency, energy-follows load components everywhere

Still challenging ourselves to think beyond the full mesh


18

SUMMARY

• Ensuring sustainable ICT network growth is necessary to enable large reductions in global carbon footprint, and for economic and societal growth

• GreenTouch™ consortium is a game-changer, focusing on innovation that will increase network efficiency a thousand-fold

• Green access is key to GreenTouch™ goals

• GreenTouch™ is starting to deliver and will need more partners and support. For more info, please visit www.GreenTouch.org

• Customer pull will accelerate commercialization of green innovations
