Low power may refer to:
* Radio transmitters that send out relatively little power:

QRP operation
In amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range. QRP operation is a specialized pursuit within the hobby that was first popularized in the early 1920s. QRP operators gener ...
, using "the minimum power necessary to carry out the desired communications", in amateur radio.

Cognitive radio
A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best wireless channels in its vicinity to avoid user interference and congestion. Such a radio automatically detects available channels in wireless spe ...
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 commonly " ...
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 communication device
A short-range device (SRD), described by ECC Recommendation 70-03, is a radio-frequency transmitter device used in telecommunication for the transmission of information, which has low capability of causing harmful interference to other radio equ ...
, a radio transmitter used in low-power broadcasting.

Low-power electronics
Low-power electronics are electronics, such as notebook processors, that have been designed to use less electric power than usual, often at some expense. In the case of notebook processors, this expense is processing power; notebook processors usu ...
, the consumption of electric power is deliberately low, e.g. notebook processors.

Power (statistics)
In statistics, the power of a binary hypothesis test is the probability that the test correctly rejects the null hypothesis (H_0) when a specific alternative hypothesis (H_1) is true. It is commonly denoted by 1-\beta, and represents the chances ...
, in which low power is due to small sample sizes or poorly designed experiments
