Sommario
On June 9th, 2025 at 1.00 pm will be held the seminar on "Towards 6G Analog Backscatter Networks" at DEIB 3B Room (Building 20).
Analog backscatter tags are ultra-low-power, resource-constrained devices that can operate using harvested energy. They are well-suited for low-cost sensor data collection. However, their simple design poses fundamental networking challenges as it comes with trade-offs such as the lack of identification mechanisms. Our work addresses these limitations by reimagining analog sensing and communication system architectures. We introduce a harmonics-based tag identification method, high-resolution sensing, and a querying mechanism for analog backscatter tags. As we move toward future 6G networks, a key goal is to accommodate a large number of ambient IoT devices through backscatter communication. Analog backscatter tags can enable large-scale, cost-effective sensor data collection. This talk highlights our group’s contributions and ongoing work on integrating analog backscatter into 6G network infrastructure.
