Abstract
A method for an electronic device to join a downlink-time difference of arrival (DL-TDoA) network as an ad hoc anchor device is provided. The method includes, determining a location of the electronic device, and determining whether a condition to operate as the ad hoc anchor device in the DL-TDoA network is satisfied. The method also includes, in response to the condition being satisfied, transmitting a request message to operate as the ad hoc anchor device in the DL-TDoA network to a server device.

A method for an electronic device to join a downlink-time difference of arrival (DL-TDoA) network as an ad hoc anchor device, comprising:
- determining a location of the electronic device;
- determining whether a condition to operate as the ad hoc anchor device in the DL-TDoA network is satisfied;
- and
- in response to the condition being satisfied, transmitting a request message to operate as the ad hoc anchor device in the DL-TDoA network to a server device.
A method for adding an electronic device as an ad hoc anchor device to a downlink-time difference of arrival (DL-TDoA) network, comprising:
- receiving a request message to operate as the ad hoc anchor device in the DL-TDoA network from an electronic device;
- determining whether the electronic device is located in a predetermined area;
- and
- in response to the electronic device being located in the predetermined area, transmitting a confirmation message to the electronic device to allow the electronic device to operate as the ad hoc anchor device.
An ultra-wideband (UWB) device, comprising:
- a transceiver operable to perform a UWB communication;
- a memory for storing program instructions, device information, device locations, conditions required for operating as an ad hoc anchor in a downlink-time difference of arrival (DL-TDoA) network;
- and
- a processor coupled to the transceiver and to the memory, wherein the processor is operable to execute the program instructions, which, when executed by the processor, cause the UWB device to perform the following operations to join the DL-TDoA network as an ad hoc anchor device, comprising:
- determining a location of the UWB device;
- determining whether a condition to operate as the ad hoc anchor device in the DL-TDoA network is satisfied;
- and
- in response to the condition being satisfied, transmitting a request message to operate as the ad hoc anchor device in the DL-TDoA network to a server device.
