    Abstract: Examples of a system and wireless RF device having an extended operational life are provided. The wireless RF device includes a substrate, at least one sensor configured to detect an occurrence of an event, a RF transceiver arranged on the substrate and configured to transmit and receive RF signals in an area, and a power supply coupled with the substrate. A processing device is coupled to the at least one sensor and the RF transceiver, and configured to: in response to expiration of a time period or the detection of the occurrence of an event, transition the RF device from a sleep or standby mode to an active mode; configure the RF transceiver to receive or transmit a data packet; obtain a status of an occurrence of another event from the at least one sensor; and transition the RF device from the active mode to the sleep or standby mode.

    Abstract: In response to receiving a lighting system element request message from a gateway to detect a subset or all wireless RF floor beacons in the space, a lighting system element receives via a local wireless communication network, a respective floor beacon identification message including a detected respective wireless RF beacon identifier transmitted from a detected respective wireless RF floor beacon. The lighting system element determines a respective RF signal strength between the detected respective wireless RF floor beacon from the respective lighting system element based on the respective floor beacon identification message. The lighting system elements transmits, via the local wireless communication network, to the gateway a respective lighting system element report message including the detected respective wireless RF beacon identifier of the detected respective wireless RF floor beacon, the respective RF signal strength, and the respective lighting system element identifier.
