[maemo-developers] [maemo-developers] WLAN reciever and battery.

[From: Charles 'Buck' Krasic]

I've read several research papers that claim that WLAN power consumption 
makes the biggest jump from completely off to online, and that the 
incremental power consumption between passive online (mainly receiving) 
and active online (transmitting) is not nearly as large.   This is why 
TDMA schemes may have major advantages for power consumption, they have 
more opportunity to turn the radio completely off.
