Cognitive radio
A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best channels in its vicinity to avoid user interference and congestion. Such a radio automatically detects available channels, then accordingly change ...
transceivers typically automatically reduce the transmitted power to much less than the power required for reliable one-way broadcasts.

Low-power broadcasting
Low-power broadcasting is broadcasting by a broadcast station at a low transmitter power output to a smaller service area than "full power" stations within the same region. It is often distinguished from "micropower broadcasting" (more common ...
that the power of the broadcast is less, i.e. the radio waves are not intended to travel as far as from typical transmitters.

Low-power electronics
Low-power electronics are electronics designed to consume less electrical power than usual, often at some expense. For example, notebook processors usually consume less power than their desktop counterparts, at the expense of computer perform ...

Power (statistics)
In frequentist statistics, power is the probability of detecting a given effect (if that effect actually exists) using a given test in a given context. In typical use, it is a function of the specific test that is used (including the choice of test ...
