Hi,
Apparently for tethering my laptop to my mobile phone I can configure to use 2.4 or 5 Ghz. So I wonder which uses less battery - on each side. If it is a significant difference.
Normally on radio higher frequency uses less energy (and reach less distance and is more directive)
Just curious! :-)
I don't know if there is more than a 'general' answer to the question. Your frequencies are generally controlled by a small clock oscillator chip (which I guess you have more than one -- they used to look like a little silver tic-tac or grain or rice, but with vertical sides. Power consumption would depend more on the specific combination of electronics needed to control a 2.4 or 5 -- and depending on the components used -- you may have results that are very different for different wifi of the same frequency (and different within the same wifi boards between versions just based on the different junk they put it together with) I wonder if you laptop power consumption widget could be fine-grained enough to tell a difference?
