ACM MobiSys is a top international conference in the field of mobile computing and is a CCF B, CUITS-recommended Class A conference that focuses on innovative, important research in areas such as mobile computing and wireless systems.The MobiSys2023 conference was held in June 2022 in Portland, Oregon, USA. The lab presented this work at the conference.
Existing backscatter systems using commodity radios all have a limited throughput, which prevents their usage in high-rate scenarios. We present SubScatter, which realizes a high throughput and keeps commodity-radio compatibility at the same time. Specifically, SubScatter boosts throughput for 11× by using 802.11b WiFi as excitation (11/8×) and designing sub-symbol modulation (8×).
