An Ocean of RF
Imagine our world filled with invisible waves from smartphones, routers, and thermostats, creating a vast ocean of RF signals. This sea of connectivity isn't just for browsing the internet or adjusting the temperature; it's also smart enough to sense everything happening inside your car. Using these signals, cars can now detect if there's a kid or a pet in the backseat, ensuring the climate control is just right and that safety features like airbags are primed perfectly based on who's onboard. It's a brilliant way to make everyday devices work together for our safety and comfort.

Synaptics' Wi-Fi SoCs output the CSI data via targeted APIs
CSI provides the knowledge of a channel through which a signal is propagating
Obstructions present in an environment cause reflection, diffraction, scattering, etc. Subtle changes to CSI can be leveraged to detect human presence or other changes to environment

Channel State Information (CSI) Based Sensing Algorithms
Managing all of the variables-the amplitudes, phases, frequency response, and SNR of potentially dozens of separate signals-to most efficiently utilize the bandwidth in the physical space requires a lot more information than just RSSI. The collected dataset aggregating all of this information is called the channel state information (CSI).
Digital Signal Processing/Machine Learning techniques decode this change in CSI components to detect motion, presence of people etc.
