    Abstract: A system includes radio frequency (RF) communication devices, for example, in luminaires, located in a service area offering a location determination service, and a portable device used in commissioning the communication devices. The communication devices transmit a primary location determination system's RF signals for receipt by the portable device. The portable device determines its location using a secondary system. The RF communication devices' transmitted RF signals include an identifier. A received signal strength indication (RSSI) of each signal received by the portable device is measured, and stored with an estimate of the portable device's corresponding location. The portable device is moved to another location to measure RSSI of RF signals. When the number of measurements or number of locations is sufficient, the locations of each of the respective luminaires or communication devices may be determined using the RSSI values and the portable device's estimated indiscriminate location.

    Abstract: A system includes a plurality of lighting devices connected in a network to communicate in a service area, and a smart tag configured to communicate with one or more of the lighting devices. Each respective lighting device is configured to transmit a radio frequency signal including a device identifier of the respective lighting device. In response to expiration of a time period or an occurrence of an event, the smart tag is configured to transition from a low power consumption sleep mode to an awake mode. During the awake mode, the smart tag is configured to provide information that enables a processor or other computing device to determine a position of the smart tag or any asset associated with the smart tag in the service area. Upon transmission of the information, the smart tag is transitioned from the awake mode back to the low power consumption sleep mode.
