VTC 2011 – GREENET Workshop Sunday

Confernces start at weekends,thats the new rule! At least the special workshop do. This year I was invited to give a plenary talk at the workshop on our (i.e. eWIN project) paper  on the characteristics of “clean slate” system design for energy and cost efficiency in mobile broadband.

The workshop was organized by the Mobile VCE and chaired by John Thompson from the Univ of Edinburgh.  The first keynote by the operator perspective from Vodofone (Davis Lister) followed by Huawei (Shugong Xu and later by Yan Chen) that presented their GREAT project. Interestingly enough in this project there is significant effort put on establishing the fundamental limits of energy efficient systems – the ideas are quite close to the ideas in the eWIN project. The energy models were, however, very detailed – I think you loose in simplicity and explanation power if you include to many details.

Ericsson representatives gave several interesting presentations  on enegry conservation techniques related to the EARTH FP7 project- in particular sleep mode techniques that seem to have a significant potential to lower energy consumption.
The final panel with the keynote speakers had some interesting questions – “what is your favourite “green technology”. Which was mine?  Save energy by predictively distributing content when the energy consumption is low !
