1. A method for updating a positioning configuration in a positioning system comprising a plurality of anchor nodes for determining positions of tag devices within a localization area using radio technology, the method comprising:
determining an updated positioning configuration for at least one of a set of tag devices and a set of anchor nodes of the positioning system based on predefined positioning requirements that depend on a zone of the localization area in which the set of tag devices is currently located; and
applying the updated positioning configuration to the at least one of the set of tag devices and the set of anchor nodes,
wherein the updated positioning configuration comprises at least one updated setting regarding at least one of: a ranging configuration used for positioning, and a communication configuration used for communication within the positioning system,
wherein the updated settings regarding the ranging configuration include updated settings regarding a specific positioning technology to be used for positioning, including at least one of: a ranging protocol to be used for positioning, a ranging frequency to be applied for positioning, a ranging trigger mechanism to be used for triggering ranging measurements used for positioning, a selection of one of a tag-to-tag ranging mode and a tag-to-anchor ranging mode to be used for positioning, and a power saving mode to be applied when performing ranging measurements, and
wherein the selection of the tag-to-tag ranging mode includes determining a master tag device among the set of tag devices with which the remaining tag devices of the set of tag devices perform pairwise proximity based ranging measurements, wherein only the master tag device is configured to perform tag-to-anchor ranging measurements representative for the whole set of tag devices, whereas positioning of other tag devices in close proximity to the master tag device is performed relative to the master tag device instead of relative to the set of anchor nodes.
