Aspects of the subject disclosure may include, for example, adaptively modifying a rate at which anchors broadcast messages into an area of interest based on tag presence status, where the messages may be used by tags to estimate tag position. Tag presence status may include an indication of whether a tag is present, a tag's position, velocity, acceleration, history, and the like. Areas of interest may be redefined based at least in part on tag presence status. Other embodiments are disclosed.

Method and system to adaptively localize a radio device

Aspects of the subject disclosure may include, for example, estimating a location of a mobile device based on a first wireless signal transmitted by one of a first group of wireless anchors of a first location service operating within a first area. Ranges between the mobile device and a group of wireless reference devices are determined responsive to the location indicating the mobile device is proximate to a predetermined transition region. A handover requirement is identified according to the range information and, responsive to this requirement, the mobile device is configured to receive a second wireless signal transmitted one of a second group of wireless anchors of a second location service operating within a second area. The location of the mobile device may be determined according to the second wireless signal, without reference to the first wireless signal. Other embodiments are disclosed.

Area handover management in real-time locating system (RTLS) networks

Aspects of the subject disclosure may include, for example, selecting, according to selection information wirelessly transmitted from one or more anchors, a particular position estimation mode from among a group of position estimation modes that are each associated with a different radio measurement locating process. One or more radio measurements can be obtained from at least one of the one or more anchors and position information can be determined for the mobile device based on the one or more radio measurements by applying a particular radio measurement locating process of the particular position estimation mode. Other embodiments are disclosed.

Method and system to select a process for estimating the location of a radio device

Aspects of the subject disclosure may include, for example, obtaining a location of a first mobile tag, responsive to detecting a second mobile tag crossing a threshold relative to the location of the first mobile tag, determining according to an activity associated with the first mobile tag, the second mobile tag, or both whether there is an association event between the first mobile tag and the second mobile tag, and responsive to determining the activity corresponds to the association event, determining whether to associate the first mobile tag and the second mobile tag. Other embodiments are disclosed.
