Introduction and Objectives - Evolution of current

is required to transfer weightless information?

4 Introduction and Objectives - Evolution of current router technology may fail in Why so much energy is required to transfer weightless information? The broadband subscribers in the world=215m in 2005(Penetration=3.35%:WHITE PAPER Information and Communications in Japan). World Population in 2020=7,500M. Energy consumption per capita =1/35 Assuming 30% penetration ratio, Energy consumption per capita in 2020=1/10 of that in 2005 (per capita) 4
