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.

Abstract
Systems, methods, apparatuses, and computer readable media are disclosed for improving, in some examples, backhaul of sensor and other data to a real time location system (RTLS) network. In the context of a method for communication by a tag, the method includes receiving, at the tag, sensor data from at least one sensor, generating, using a processor of the tag, a tag blink data packet, the tag blink data packet including a tag identifier and at least a portion of the received sensor data, and transmitting the tag blink data packet.
