Demo - PicoScenes - Enabling UWB Sensing Array on COTS Wi-Fi Platform.

Radio Frequency (RF) sensing based on Commercial OffThe-Shelf (COTS) Wi-Fi devices is recently a hot research topic. However, the pursuit of higher sensing accuracy is severely hampered by the limited spectrum and insufficient number of antennas. In this paper, we release PicoScenes, a sophisticated NIC control and CSI measurement tool that overcomes the above limitations. PicoScenes comprises a three-layered architecture, i.e. PicoScenes Driver, Platform and Plug-in Development Kit (PSPDK). In the bottom layer, we unlock the Ultra-wideband (UWB) access for Atheros 9300 NIC (a.k.a QCA9300), and enable the multiNIC CSI measurement for both Intel 5300 (a.k.a IWL5300) and QCA9300. In the middle layer, PicoScenes Platform wraps all the low-level NIC controls, and provides a powerful and efficient runtime APIs for PSPDK. And in the upper layer, we develop PSPDK-based plug-ins and achieve msgrade UWB spectrum sensing on a large-scale NIC array.
