Abstract: The present invention relates to a method, a system and a computer program product for determining a position relative to a confined space. For this purpose, one or more UWB anchors are provided on the confined space, a distance of the UWB item relative to the one or more UWB anchors is repeatedly determined, a variability is determined based on the repeatedly determined distances and it is determined whether the UWB item is in the confined space, by comparing said variability with a predetermined variability limit value.
Abstract: The invention relates to a method, system and computer program product for determining a distance between persons by means of a plurality of battery powered devices. The device is configured to perform a typical and atypical operating pattern, with the advantage of a longer device operating time.
