Methods and devices related to determining a propagation time of wireless transmissions between wireless communication devices are provided. A propagation time of wireless transmissions between a first wireless communication device and a second wireless communication device is determined. The determining is based on a roundtrip time of a wireless transmission exchange between the first wireless communication device and the second wireless communication device, a reply time of the wireless transmission exchange, and on the first time interval and the second time interval. The first time interval is a time interval between a first transmit event at the first wireless communication device and a second transmit event at the first wireless communication device. The second time interval is a time interval between a first receive event at the second wireless communication device and a second receive event at the second wireless communication device.

Embodiments generally relate to a machine-implemented method of automatically adjusting the range of a depth data recording executed by at least one processing device. The method comprises determining, by the at least one processing device, at least one positions of a subject to be recorded; determining, by the at least one processing device, at least one spatial range based on the positions of the subject; receiving depth information; and constructing, by the at least one processing device, a depth data recording based on the received depth information limited by the at least one spatial range.
