Study of Simultaneous Wireless Information and Power Transfer (SWIPT) in 5G - IoT

Abstract

The SWIPT technology, recognized as a wireless energy harvesting technique to steer the advancement of subsequent generations of wireless systems, namely 5G and its successors. The Internet of Things is anticipated to enhance the life of human quality, though IoT devices are confronted with energy limitations stemming from available resource constraints. In recent years, SWIPT-based radio frequency will be regarded as a promising energy harvesting technique likely there will be an increase in number of devices connected to networks and applications in near future, which will increase the demand for next-generation wireless communications, causes an increase in energy consumption. As a consequence, energy harvesting and data transmission are necessary for the energy-efficient communication, therefore, green communications based on SWIPT are expected to become an essential component of both 5G and 5G+. SWIPT systems conventionally utilize ambient signals for both information transfer and energy supply. As such, the present dissertation endeavors to scrutinize SWIPT communication with the aim of engendering enhanced comprehension of the system's operation and performance. This paper reviews two levels of literature on multiuser SWIPT communications for 5G. First, SWIPT enabled the selective OFDM model. Second, SWIPT-enabled mm-wave propagation was reviewed for system characterized to 5G IoT devices.
