The Internet of Things (IoT) continues to grow at remarkable speed, connecting different devices and facilitating communication and data exchange. Ambient Backscatter Communication (AmBC) has emerged as a low-power, low-cost alternative suitable for the connectivity of IoT. However, this technology still requires development to be adopted on a large scale. In this paper, we present a brief overview of AmBC, and highlight how it is appealing for IoT. We then go over the major challenges that AmBC faces with a concise explanation for each, as well as outline the directions future research should take to enhance the performance AmBC and push its integration with IoT forward. We also include a survey of some contributions in this domain. © 2025 IEEE.
