An apparatus configured at least to perform: receiving a signal constituting a positioning packet at a positioning device; processing the signal by: demodulating a header of the positioning packet from the signal; extracting an identifier from the header of the positioning packet; part processing samples of the signals; and forming a message from the part-processed samples; in response to receiving the signal, deactivating a receiver circuit of the positioning device for a period of time, the period of time constituting a sum of a time taken by the positioning device to process the signal and a preconfigured or random delay time; and activating the receiver circuit of the positioning device immediately subsequent the period of time.

Positioning devices

A system for implementing a positioning functionality. An apparatus (e.g. a directional transceiver) () may receive a signal () for positioning and measure characteristics associated with the received signal (). If the directional transceiver () then determines that the received signal () comprises calculator identifier information, the apparatus may forward the measured characteristics based on the calculator identifier information. Otherwise, the directional transceiver () may forward the measured characteristics to a buffer (). From the perspective of the apparatus () transmitting the signal () for positioning, a determination may be made as to whether calculator identifier information is known. If determined to be known, the transmitting apparatus () may include the calculator identifier information in the signal () for positioning. Otherwise, the other apparatus may transmit the signal () for positioning without any calculator identifier information.
