Technique for locating a target tag

A method for locating a target tag using a short range radio based positioning system comprising a plurality of localization components, the target tag and the plurality of localization components being configured to perform ranging measurements among each other using short range radio technology, the method comprising the target tag:

• receiving, using long range radio technology, a ranging plan from an orchestration component of the positioning system, the ranging plan instructing the target tag to perform, using the short range radio technology, ranging measurements with one or more of the plurality of localization components enabling to locate the target tag, wherein, upon receiving the ranging plan, the target tag switches into a sleep mode and wakes up at the at least one timeslot in which the ranging measurements are to be performed with the one or more of the plurality of localization components.

• receiving, using long range radio technology, a ranging plan from an orchestration component of the positioning system, the ranging plan instructing the localization component to perform, using the short range radio technology, a ranging measurement with the target tag to be used in locating the target tag;
• and
• receiving from the orchestration component, prior to receiving the ranging plan and using the long range radio technology, an indication of a listening timeslot to listen for a ping sent out from the target tag using the short range radio technology, wherein, upon receiving the indication of the listening timeslot, the localization component switches into a sleep mode and wakes up at the listening timeslot.
