Abstract
Methods, systems, and devices for automatically changing the manner in which a tag unit communicates with one or more access points based on the tag unit's mobility state are described. A tag unit may transmit ultra-wideband (UWB) signals in a low update mode while in a stationary state. The tag unit may transmit UWB signals in a high update mode while in a mobile state. The tag unit, an access point, and/or a tracking management server may determine a tag unit's mobility state and adjust an update mode based on the mobility state.
Claims40
A method of communicating with a location tracking tag in a location tracking system, comprising:
- determining a mobility state of the location tracking tag comprising at least a narrowband transceiver and at least an ultra-wideband (UWB) transmitter;
- upon determining the mobility state of the location tracking tag is stationary, operating the location tracking tag in a low update mode while the tag is stationary;
- and
- upon determining the mobility state of the location tracking tag is mobile, operating the location tracking tag in a high update mode while the tag is mobile.
A system for communicating with a location tracking tag in a location tracking system, comprising:
- means for determining a mobility of the location tracking tag, the locating tracking tag comprising at least a narrowband transceiver and at least an ultra-wideband (UWB) transmitter;
- means for operating the location tracking tag in a low update mode while the tag is stationary, the means for operating configured to operate upon a determination that the mobility state of the location tracking tag is stationary;
- and
- means for operating the location tracking tag in a high update mode while the tag is mobile, the means for operating configured to operate upon a determination that the mobility state of the location tracking tag is mobile.
A location tracking tag apparatus for communicating in a location tracking system, the apparatus comprising:
- a processor in electronic communication with at least a narrowband transceiver and at least an ultra-wideband (UWB) transceiver;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- determine a mobility state of the location tracking tag;
- upon determining the mobility state of the location tracking tag is stationary, operate the location tracking tag in a low update mode while the tag is stationary;
- and
- upon determining the mobility state of the location tracking tag is mobile, operate the location tracking tag in a high update mode while the tag is mobile.
A computer-program product for operating a location tracking tag in a location tracking system, the computer-program product comprising a non-transitory computer-readable medium storing instructions executable by a processor to:
- determine a mobility state of a the locating tracking tag, which comprises at least a narrowband transceiver and at least an ultra-wideband (UWB) transmitter;
- upon determining the mobility state of the location tracking tag is stationary, operate the location tracking tag in a low update mode while the tag is stationary;
- and
- upon determining the mobility state of the location tracking tag is mobile, operate the location tracking tag in a high update mode while the tag is mobile.
