Multi-band wi-fi fusion for wlan sensing

Abstract

A system for fusion of Wi-Fi measurements from multiple frequency bands to monitor indoor and outdoor space is provided. The system includes a multi-band wireless network comprising a set of radio devices to provide coverage in an environment, wherein the set of radio devices are configured to establish wireless communication or sensing links over multi-band wireless channels, wherein the multi-band wireless channels use a first radio band at a millimeter wavelength and a second radio band at a centimeter wavelength. The system further includes a computing processor communicatively coupled to the set of radio devices and a data storage, wherein the data storage has data comprising a parameterized model, modules and executable programs. The computing processor is configured to receive measurement data over the multi-band wireless channels to obtain a set of heterogeneous sensor data, network transferred data, or wireless channel attribute data, fuse at least two types of measurements from the first and the second radio bands at one or more steps in a parameterized model to generate an estimated environmental state in the environment.
