Abstract

Methods, apparatus and systems for qualified wireless sensing are described. In one embodiment, a described method comprises: transmitting a wireless signal from a Type 1 device to a Type 2 device through a wireless multipath channel of a venue; obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the wireless signal; performing a qualification test based on the TSCI for at least one to-be-qualified device, which is at least one of: the Type 1 device, a module of the Type 1 device, an integrated circuit (IC) of the Type 1 device, the Type 2 device, a module of the Type 2 device, or an IC of the Type 2 device; determining that each of the at least one to-be-qualified device is a qualified device based on a determination that a respective qualification criterion associated with the to-be-qualified device is satisfied, to obtain at least one qualified device; and performing a task based on the TSCI using the at least one qualified device.
