An example radio frequency (RF) positioning node system calculates a respective distance between an uncommissioned RF positioning node to each of neighboring commissioned RF positioning nodes based on a respective received signal strength indicator (RSSI) measurement. Based on the calculated respective distance to each of the neighboring commissioned RF positioning nodes and a set of commissioned location coordinates of each of the neighboring commissioned RF positioning nodes, the RF positioning node system estimates a set of uncommissioned location coordinates of the uncommissioned RF positioning node. The RF positioning node system determines a best fit assignment of the set of uncommissioned location coordinates of uncommissioned RF positioning nodes in an uncommissioned RF positioning node list to the set of commissioned location coordinates of non-operational commissioned RF positioning nodes in a non-operational RF positioning node list to adjust an RF positioning node map for each of the non-operational commissioned RF positioning nodes.

Self-healing in a luminaire or other radio frequency positioning node based system

A luminaire-based positioning system including a plurality of luminaires, each respective luminaire including a luminaire identifier. The system includes a gateway including a luminaire node map of commissioned luminaires with a commissioned luminaire identifier and commissioned location coordinates of each commissioned luminaire. The gateway includes an undesignated luminaire roster of undesignated luminaires with a set of undesignated location coordinates. Further, the gateway includes a plurality of projected received signal strength indication (RSSI) values. Additionally, the gateway includes programming to determine an association of an uncommissioned luminaire to a safest fit undesignated luminaire of the undesignated luminaire roster. Further, programming to assign to the uncommissioned luminaire the set of undesignated location coordinates of the safest undesignated luminaire. Additionally, programming to adjust the luminaire node map by adding a new set of commissioned location coordinates with the uncommissioned luminaire identifier that most safely fit the determined set of uncommissioned location coordinates.

An example luminaire-based positioning system calculates a respective distance between an uncommissioned luminaire to each of neighboring commissioned luminaires based on a respective received signal strength indicator (RSSI) measurement. Based on the calculated respective distance to each of the neighboring commissioned luminaires and a set of commissioned location coordinates of each of the neighboring commissioned luminaires, luminaire-based positioning system estimates a set of uncommissioned location coordinates of the uncommissioned luminaire. The luminaire-based positioning system determines a best fit assignment of the set of uncommissioned location coordinates of uncommissioned luminaires in an uncommissioned luminaire list to the set of commissioned location coordinates of non-operational commissioned luminaires in a non-operational luminaire list. The luminaire-based positioning system adjusts a luminaire node map for each of the non-operational commissioned luminaires based on the determined best fit assignment.

The disclosure provides an example of a system including a radio frequency (RF) nodal network and a gateway coupled to the RF nodal network. The gateway is configured to transmit control packets the control packets having an initial parameter setting for each node in the RF nodal network. The selected nodes among the network of nodes are configured to transmit a number of test packets for each of a plurality of tests is greater than throughput saturation of the RF nodal network. The system includes a server coupled to the gateway and is configured to perform network performance analysis based on the test packets for each of the plurality of tests received by the gateway. The server updates parameter settings to optimize performance of the nodes of the RF nodal network to attain the target network performance metric based on a result of the network performance analysis.
