Re: [v6ops] Interest in energy consumption of IPv6 smartphones (vs. IPv4)

[Olivier MJ Crepin-Leblond <[e-mail]>]

Hello all,

it is also worth noting that 3G & 4G in particular appears to drain
battery more than 2G. Results could be flawed because due to novelty, in
most places 4G signal strength is not yet at the level of 2G or 3G
signal strength. A study under controlled environment would be somehow
interesting indeed although I fail to see the end goal for performing
such a study? Do we want to prove that longer addresses mean more power
requirements? I would have thought the end point really relates to
chipset architecture, not bits transmitted.
Kindest regards,

Olivier
