POWER EFFICIENT AND FLEXIBLE UPDATE RATE POSITIONING SYSTEM |
摘要 |
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. |

1. 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. |
