Operator’s Demand
Operator’s Demand
Per-user power reduced by 20% @ 2020 ()
CO2 emission reduced by 80% @ 2020 ()
“Green Action Programme ”starts up now!
“power consumption per traffic in 2010 lower 40% than 2005
Lower power consumption, save source, CO area and cost, waste recycle
“Low energy is key performance”, said by TI CTO Stefano Pileri
Develop energy saving plan for NGN2
Improve equipment EE by 20% in 2009
, ON, DC as pliance
“Green plan”–change work environment to energy saving mode
Cooperate with Verizon, anize ATIS NIPP TEE standard
Take energy consumption as key element
CO2 emission in 2010 lower 50% than 1995
Initiate CO900 project
Improve equipment EE by 30% energy saving -- CEO Cesar Alierta
Total power, petrol, water consumption
Energy consumption per unit in 2011 lower by 40% than that of 2005
Lower power consumption and improve EE

Green Radio – A key enabler
Green Radio --
A key enabler for sustainable munication business
Big gap
Traffic
Data
Voice
Revenue
Trends
Exponential growth in data traffic
Number of base stations / area increasing for higher capacity
Revenue growth constrained and dependent on new services
Carriers under pressure to dramatically reduce TCO and energy bill
Consequences
Energy use cannot follow traffic growth without significant increase in energy consumption MUST REDUCE Energy Per Bit
Number of base stations increasing MUST REDUCE Operating Power Per Cell to save TCO
