Abstract
According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: obtaining a position of a user device; locating one or more surfaces providing one or more putative reflection points for a non-line-of-sight (NLOS) path between the user device and a wearable device; conditional upon locating the one or more surfaces, causing ranging signals to be exchanged between the user device and the wearable device to determine a relative position of the wearable device with respect to the user device; determining, from at least the relative position and position of the user device, data that enables calibration of one or more sensors of the wearable device; and causing transmission of the data to the wearable device.
