| Abstract: | : | Wireless radios form the fabric of connected devices today. However, such radios have traditionally been used for data communication tasks. This talk will focus on exploring the re-use of these radios as a potential sensing modality. Given the pitfalls of visual sensing that includes privacy regulations, dependency on blockages/lighting conditions, bandwidth usage, local/edge compute load and so on, wireless sensing fundamentally addresses some of these challenges. This creates a context where wireless sensing, independently or in augmentation to existing visual sensing can robustly "IoT-ize" sensing solutions. We will look at the systems challenges to perform such sensing locally on low-end embedded devices or at the edge. Second, given the inherent broadcast nature of the wireless medium, we will introduce situations when wireless sensing can be adversarially exploited leading to leakage of sensitive contextual information. Overall, the talk will encompass wireless communication radios as an upcoming sensing modality and related end-to-end system design challenges. |
