Don't listen, talk: A comparative study of transmit and receive power for low power radios
Adam Greenhalgh, Stephen M. V. Hailes · UCL Discovery (University College London) · 2004
In this paper we investigate the energy consumption of a low power radio device in its three modes of operation: transmission, reception and idle. We identify these modes of operation from the traces of the energy consumption of the device by modifying the device’s firmware to include and exclude certain events. We present energy consumption measurements two orders of magnitude lower than an 802.11 device and question whether the use of 802.11 figures in simulations of low power radio systems is realistic. Contrary to 802.11 models, we show Prx > Ptx > Pidle.
