Efficient energy utilization is among the main challenges of future communication networks to extend their lifetime and reduce operating costs. Networks are generally populated by battery-dependent devices. In some cases, such dependency is relevant at a point in which the battery lifetime often represents a bottleneck for the network lifetime as well. Within this context, wireless energy transmission becomes an alternative to eliminate the need for in-situ battery recharging. Nonetheless, for decades, the traditional engineering perspective was to design separately information transmission systems and energy transmission systems. However, this approach has been shown to be suboptimal. Indeed, a radio frequency (RF) signal carries both energy and information. From this standpoint, a variety of modern wireless systems and proposals question the conventional separation approach and suggest that RF signals can be simultaneously used for information and energy transmission. This tutorial starts from this observation and aims at familiarizing the attendees with the new communication paradigm of simultaneous wireless information and energy transfer (SWIET) in wireless networks, and its associated challenges.
