This work is part of a project where the goals are: designing energetically-optimum domestic WiFi routers; obtaining real and accurate power consumed models as a function of router configuration, and providing the community with an active power waveforms database, useful for considering power consumption as a part of WiFi networks design and optimization. In particular, in this paper we started by measuring the active power consumption of a standard router under several scenarios. These take into account physical transmission rates, operation modes (transmitting/receiving), transmission powers, compatibility modes, type of traffic, packet sizes, encryption, ethernet connections, ... The paper reports the setup, measurement method, the first results and conclusions where the impact of the AC/DC converter on the power consumed is also considered.
