Abstract

A computerized method of mapping a plurality of anchor devices in a space. The method, providing a plurality of anchor devices which are set to be detachably deployed in a plurality of locations in a space, capturing by the plurality of anchor devices a plurality of relative distance indication messages transmitted from the plurality of anchor devices, calculating, based on each the relative distance indication message, distance indicative parameters indicative of a distance between a pair of anchor devices from the plurality of anchor devices, aggregating the distance indicative parameters, and calculating a dataset which maps a location of each one of the plurality of anchor devices in the space according to the aggregated distance indicative parameters.

Claims

aggregating said distance indicative parameters Which are relayed over said wireless me sh; and

calculating a dataset which maps a location of each one of said plurality of anchor devices in said space according to said aggregated distance indicative parameters.

3. The method of claim 1, further comprising:

receiving reference location coordinates of one of said plurality of anchor devices; and

setting said location of each one of said plurality of anchor devices according to said reference location coordinates.

4. The method of claim 3, wherein said reference location coordinates are received from an external mapping device.

5. The method of claim 1, wherein each said anchor device is housed in a housing having an attachment element for detachably deploying said anchor device to an object within said space.

6. The method of claim 1, wherein said aggregating comprises transmitting said distance indicative parameters from each one of at least some of said plurality of anchor devices to a location computing unit.

14. The method of claim 1, wherein said plurality of anchor devices are divided into a plurality of groups so that some of the members of said group is in an effective transmission range from each another member of said group;

and wherein said calculating a dataset that comprises generating a plurality of subset datasets each of another said group and combining said plurality of subset datasets.

16. The method of claim 1, wherein said space is a multi-storey building and said plurality of anchor devices are divided into a plurality of groups so that each said group is located in another storey if a multi-storey building;

and wherein said calculating a dataset that comprises generating a plurality of subset datasets each of another said group and combining said plurality of subset datasets.

17. The method of claim 1, wherein said plurality of anchor devices comprises a plurality of intermediate anchor devices that belong to more than one group of anchor devices, and enables to map the locations of anchor devices in one group relative to the locations of anchor devices of another group.

18. The method of claim 1, further comprising:

receiving a plurality of signals indicative of a movement of at least one entity in said space using at least one tracking unit in at least some of said plurality of anchor devices; and

wherein said tracking is performed using said dataset.

23. The method of claim 18, further comprising adding at least one posteriori reference location point according to the location of said at least one entity in an event triggered by said at least one entity, said at least one posteriori reference location point maps a location of an object in said space.

24. The method of claim 1, further comprising receiving distance indicative parameters indicative of a new distance between a new anchor device and at least three of said plurality of anchor devices and updating said dataset to map the location of said new anchor device in said space according to said new distance and data from said dataset.

26. The method of claim 1, further comprising detecting a relocation of one of said plurality of anchor devices and repeating said capturing, said calculating, said aggregating, and said calculating in response to said detection.

27. The method of claim 1, wherein said calculating a dataset comprises setting said location of each one of said plurality of anchor devices according to a physical location of one of said plurality of anchor devices.
