Data communication, parametric sensing and remote powering are the three fundamental functions of wireless technology. Such functions and operations have been enabled independently so far by various RF and wireless transceivers. On the other hand, the recent research of transceiver architectures has spurred the development of emerging system solutions featuring lowpower, self-adaptation and scalable integration. Smart system fusion of multiple wireless functions would definitely generate many inestimable lasting benefits within those novel transceiver design frameworks such as architecture unification, simplification, miniaturization and reconfiguration in addition to efficiency enhancement, function interplay and cost reduction. This presentation presents and discusses a number of emerging advances in the development of multi-function transceivers and system integrations over MHz-through-THz. State-of-the-art linear and non-linear techniques are reviewed with reference to multi-band and multi-structure transceiver hardware development. Theoretical and experimental demonstrations are exemplified and provided in connection with current wireless system development such as 5 G, IoT and beyond. Future research topics in this direction are also highlighted.
