It seems one use-case would be exfiltrating and C&C of an APT hosted on a wifi device, where IDS would not see any exfil traffic on the wifi, yet the wifi device could use the doppler side channel as a covert channel.
I'm not so sure about the practicality, as the authors claim it would be useful for integrating into existing networks, but it would mean updating the firmware of the devices (both WiFi and BLE devices) anyway. At that point you might simply add BLE capabilities to WiFi routers, which takes half the time or less... or am I missing an obvious use-case here?
