On the power efficiency of sensory and ad-hoc wireless networks [PDF]

open access: yesIEEE International Symposium on Information Theory, 2003. Proceedings., 2003
We consider the power efficiency of a communications channel, i.e., the maximum bit rate that can be achieved per unit power (energy rate). For additive white Gaussian noise (AWGN) channels, it is well known that power efficiency is attained in the low signal-to-noise ratio (SNR) regime where capacity is proportional to the transmit power.
