Towards 6G Ambient IoT with Backscatter and Intermittent Computing
6G Ambient IoT is expected to enable a wide range of new IoT applications across various industries, driven by the ability to deploy and manage billions of interconnected devices.
6G Ambient IoT devices rely on energy harvesting rather than batteries which makes ultra-low power consumption a key issue. To address this challenge, 6G Ambient IoT devices use backscatter communication which reduces the energy consumption by several orders of magnitudes compared to conventional active radios. As the telecommunications industry drives the development of 6G, the primary focus remains on efficient communication. In this talk, I first present some key technologies of 6G Ambient IoT. I will discuss harmonic backscatter, an approach that avoids self-interference between the carrier and data radio frequency waves. I will then present TaDA, a task decoupling architecture for energy harvesting devices and discuss its potential role in 6G Ambient IoT.
