In this paper, we propose a dual mode simultaneous wireless information and power transfer (SWIPT) system in which a sensor node monitors the received power and adaptively controls the communication mode. To this end, we design two types of single and multi-tone waveforms and propose a new transceiver architecture that realizes adaptive power management and information decoding (adaptive PM-\&-ID) module. On top of this, we implement adaptive PM-\&-ID policy algorithm which reflects non-linear energy harvesting (EH) model for both single and multi-tone waveforms. Our newly designed SWIPT can be applied to Internet-of-Things (IoT) network with RF EH capability for self-powering, leading to battery-free network. Numerical results show that significant performance gain can be achieved by the proposed dual mode SWIPT over the existing SWIPT design.
