1. A method comprising:

  • generating a tag-sensor correlator indicative of an association between a sensor and a radio frequency (RF) location tag, wherein;

    the sensor includes a first transmitter configured to wirelessly transmit signals to a first type of wireless receiver,the RF location tag includes a second transmitter configured to wirelessly transmit blink data packets to a second type of wireless receiver different than the first type of wireless receiver, andthe second type of wireless receiver is configured to measure times of arrival corresponding to the blink data packets;

    generating, using the sensor, sensor data including an environmental measurement;

    transmitting the environmental measurement from the sensor directly to the first type of wireless receiver;

    generating sensor metadata that identifies the sensor data; and

    transmitting the sensor metadata from the sensor to the RF location tag, wherein the RF location tag is to transmit the sensor metadata to the second type of wireless receiver, and the tag-sensor correlator is used by a processor to associate the environmental measurement with location data derived from the blink data packets transmitted by the second transmitter and generated by the RF location tag.
