Abstract

In one aspect, a controller associated with an Ultra-Wide Band (UWB) network may analyze plurality of ranging methods utilized by a plurality of anchors of the UWB network to synchronize respective timings for tracking one or more tags in a geographic area. The controller may also determine a first ranging round structure that accommodates a first pair of ranging methods of the plurality of ranging methods. The first pair of ranging methods may include two distinct ranging methods of the plurality of ranging methods. The controller may transmit a first synchronization signal based on the first ranging round structure to at least a subset of the plurality of anchors to synchronize transmissions associated with tracking the one or more tags.

2 . The computer-implemented method of claim 1 , further comprising:
determining a second ranging round structure that accommodates a second pair of ranging methods of the plurality of ranging methods, wherein the second pair of ranging methods includes two distinct ranging methods of the plurality of ranging methods; and transmitting a second synchronization signal based on the second ranging round structure to at least the subset of the plurality of anchors, wherein the second ranging round structure is sequential to the first ranging round structure, wherein the second ranging round structure accommodates a second pair of ranging methods, and wherein the second pair of ranging methods is comprised of two distinct ranging methods of the plurality of ranging methods.

3 . The computer-implemented method of claim 2 , wherein the second ranging round structure is different from the first ranging round structure, and wherein the second pair of ranging methods is distinct from the first pair of ranging methods.

4 . The computer-implemented method of claim 2 , further comprising:
transmitting, by the controller, instructions associated with the first ranging round structure or the second ranging round structure to at least the subset of the plurality of anchors of the UWB network.

5 . The computer-implemented method of claim 1 , wherein the first ranging round structure is transmitted by the controller using an out-of-band method.

6 . The computer-implemented method of claim 1 , wherein the plurality of ranging methods include at least Two-Way Ranging (TWR), Uplink Time Difference of Arrival (UL TDoA), and Downlink TDoA (DL TDoA).

7 . The computer-implemented method of claim 1 , wherein the first ranging round structure is sub-divided into one or more segments, wherein each segment of the one or more segments is associated with at least one of a respective ranging method and a synchronization signal.

8 . A system comprising:
one or more processors; and a memory storing instructions that, when executed by the one or more processors, configure the system to:
analyze, by a controller associated with an Ultra-Wide Band (UWB) network, plurality of ranging methods utilized by a plurality of anchors of the UWB network to synchronize respective timings for tracking one or more tags in a geographic area;
determine a first ranging round structure that accommodates a first pair of ranging methods of the plurality of ranging methods, wherein the first pair of ranging methods includes two distinct ranging methods of the plurality of ranging methods; and
transmit a first synchronization signal based on the first ranging round structure to at least a subset of the plurality of anchors to synchronize transmissions associated with tracking the one or more tags.

9 . The system of claim 8 , wherein the instructions further configure the system to:
determine a second ranging round structure that accommodates a second pair of ranging methods of the plurality of ranging methods, wherein the second pair of ranging methods includes two distinct ranging methods of the plurality of ranging methods; and transmit a second synchronization signal based on the second ranging round structure to at least another subset of the plurality of anchors, wherein the second ranging round structure is sequential to the first ranging round structure, wherein the second ranging round structure accommodates a second pair of ranging methods, and wherein the second pair of ranging methods is comprised of two distinct ranging methods of the plurality of ranging methods.

10 . The system of claim 9 , wherein the second ranging round structure is different from the first ranging round structure, and wherein the second pair of ranging methods is distinct from the first pair of ranging methods.

11 . The system of claim 9 , wherein the instructions further configure the system to:
transmit, by the controller, instructions associated with the first ranging round structure or the second ranging round structure to at least the subset of the plurality of anchors of the UWB network.

12 . The system of claim 8 , wherein the first ranging round structure is transmitted by the controller using an out-of-band method.

13 . The system of claim 8 , wherein the plurality of ranging methods include at least Two-Way Ranging (TWR), Uplink Time Difference of Arrival (UL TDoA), and Downlink TDoA (DL TDoA).

14 . The system of claim 8 , wherein the first ranging round structure is sub-divided into one or more segments, wherein each segment of the one or more segments is associated with at least one of a respective ranging method and a synchronization signal.

15 . A non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium including instructions that when executed by a computer, cause the computer to:
analyze, by a controller associated with an Ultra-Wide Band (UWB) network, plurality of ranging methods utilized by a plurality of anchors of the UWB network to synchronize respective timings for tracking one or more tags in a geographic area; determine a first ranging round structure that accommodates a first pair of ranging methods of the plurality of ranging methods, wherein the first pair of ranging methods includes two distinct ranging methods of the plurality of ranging methods; and transmit a first synchronization signal based on the first ranging round structure to at least a subset of the plurality of anchors to synchronize transmissions associated with tracking the one or more tags.

16 . The non-transitory computer-readable storage medium of claim 15 , wherein the instructions further configure the computer to:
