An electronic device is operated by determining its location on a body of a human or an animal, as an ending point of a path from another electronic device. The path is predetermined by measuring at multiple frequencies, a property indicative of loss of an AC signal that propagates through the body along the path between the pair of electronic devices, to obtain measurements. The multiple measurements are thereafter used to select a particular path through the body, from among a group of paths through the body which are characterized in one or more training phases, e.g. by use of a classifier. After a particular path through the body is identified, based on an ending point of the particular path, an electronic device at that ending point is configured, e.g. by turning on or turning off a specific sensor, or by setting a rate of transmission of data.
