Space characterization using electromagnetic fields

摘要

The space characterization system may obtain readings from devices with electromagnetic (EM) field radios. Based on the readings, static and moving objects may be detected. The space characterization system may allow EM-based sensing of objects and room configuration, which may be based on collaboration of devices with EM radios across different EM spectra. The EM-based sensing of objects and room configuration may be used by vehicles for navigation.
