Advanced PicoScenes (2): Arbitrary Carrier Frequency Tuning

Enabling UWB Sensing on Commodity Wi-Fi Devices

In this tutorial, we explore a much more valuable feature of PicoScenes: arbitrary carrier frequency tuning, or enabling Ultra Wide Bandwidth (UWB) sensing on commodity Wi-Fi devices. Two ways are provided to access this feature: Carrier Frequency Direct Tuning, and Carrier Frequency Scanning. In the following text, I use CF for the abbreviation of Carrier Frequency. Carrier Frequency Direct Tuning Tuning NIC phy0 to an arbitrary CF demands only one argument: –freq. [Read More]

Advanced PicoScenes (1): Injection with ACK

ms Grade BI-DIRECTIONAL CSI Measurement

The previous tutorial introduces PicoScenes and exemplify the simple injector and logger modes. In this tutorial, we move forward to an advanced feature of PicoScenes: Injection with ACK, or chronos-initiator and chronos-responder modes. For a simple description, these two modes working together enable BI-DIRECTIONAL CSI measurement with ms grade round-trip delay (RTD). This tutorial is an extended topic on PicoScenes. You should refer the previous tutorial for basic usage of PicoScenes. [Read More]
