"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."
Ah yes:

Looks very cool. Thanks for posting this.
