The Drive for Bandwidth

Faster, fatter = higher power(unless we change)

Bigger, better amplifiers

Power hungry base stations

Going Green

Efficient wireless

Backhaul challenge

Energy efficient multipliers

Spectrum awareness

Green = Reduced OPEX !

- 2020 Vision -

Environment/Energy/Spectrum

Arguably what is needed are wireless access systems that can supportmultimedia

service data rates attwo or three orders of magnitude lower transmission powerthan

currently used. Performance of todays radio access technologies is in fact already

approaching the Shannon Bound such an advance will not come simply from more

traditional research on single aspects of the physical layer, but will require holistic,

system-wide, breakthrough thinking that challenges basic assumptionsMobile VCE consultation paper, 2020 VisionEnabling the Digital Future Dec07

Embodied energy Energy used in raw material

extraction, transport, manufacture,

assembly, installation of a product orservice including disassembly,

deconstruction and decomposition.

In VLSI devices the embodied energy can be 2.5

3 times the operating energy, recycling helps

But.Dont forget customer

premises energy bill. This is

not about bill offload.
