RF body reflections ... so radar? Ah yes: "To address these challenges, WiZ builds on Frequency Modulated Carrier Waves (FMCW), a radar technique that provides TOF measurements. WiZ introduces multi-shift FMCW, a multi-antenna extension to FMCW where the signal transmitted by different antennas is structured in a particular way to disentangle the TOFs corresponding to different people and eliminate the impact of fictitious TOFs that do not correspond to a physical target." Looks very cool. Thanks for posting this.
