Abstract
The present teaching relates to collecting and processing location-specific wireless waveforms for use in wireless communication, components, methods, apparatuses, servers, and systems. In one embodiment, a disclosed system comprises a first wireless transceiver of a first device, and at least one second wireless transceiver of at least one second device. The first wireless transceiver of the first device is wirelessly coupled to the at least one second wireless transceiver through a wireless multipath channel associated with a space. The first device with the first wireless transceiver comprises a processor and a memory, which are configured to obtain a set of channel information (CI) and perform a task associated with the space based on the set of channel information. The set of channel information is captured when at least one probing signal is either (1) sent from the first wireless transceiver to a particular second wireless transceiver through the wireless multipath channel associated with the space, or (2) sent from the particular second wireless transceiver to the first wireless transceiver through the wireless multipath channel. The set of CI comprises a channel impulse re…
