A method, system and apparatus are provided for estimating at least one characteristic of a wireless communication channel between at least two passive backscattering radio frequency (RF) nodes, the method including measuring backscatter channel state information (BCSI) during communication between the at least two passive RF nodes; estimating, by at least one RF node of the at least two passive RF nodes, the at least one characteristic of the wireless communication channel based on the measured BCSI.

Method for passive wireless channel estimation in radio frequency network and apparatus for same

A method, system and apparatus are provided for estimating characteristics of a wireless communication channel between at least two passive radio frequency (RF) nodes. Backscatter channel state information (BCSI) is measured during communication between the at least two passive RF nodes using the wireless communication channel. An RF node aggregates the measured BCSI and the aggregated BSCI is analyzed to detect at least one activity of a plurality of activities.
