In electronics, low power may mean:

  • Radio transmitters that send out relatively little power.
    • QRP operation, using "the minimum power necessary to carry out the desired communications", in amateur radio.
    • Cognitive radio transceivers typically automatically reduce the transmitted power to much less than the power required for reliable one-way broadcasts.
    • Low-power broadcasting 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 radio transmitter used in low-power broadcasting.
  • Low-power electronics, the consumption of electric power is deliberately low, e.g. notebook processors.
