US 2026/0312840 A1 · METHOD, APPARATUS, AND SYSTEM FOR WIRELESS SENSING BASED ON MULTIPLE GROUPS OF WIRELESS DEVICES

Abstract

Methods, apparatus and systems for wireless sensing using multiple groups of wireless devices are described. In one example, a described system comprises: heterogeneous wireless devices in a venue, and a processor. A particular device is configured to communicate with a first device through a first wireless channel based on a first protocol using a first radio, and configured to communicate with a second device through a second wireless channel based on a second protocol using a second radio. The processor is configured for: obtaining a time series of channel information (TSCI) of the second wireless channel based on a wireless signal communicated between the particular device and the second device; computing a pairwise sensing analytics based on the TSCI; and computing a combined sensing analytics based on the pairwise sensing analytics. The particular device transmits the combined sensing analytics to the first device, to perform a wireless sensing task.
