7. The apparatus of claim 1 , wherein the tag participant correlator is configured for storing with a participant profile comprising biometric data and role data.
8. The apparatus of claim 1 , wherein the tag derived data and the second tag derived data comprise time of arrival measurement data and tag information packets.
9. The apparatus of claim 1 , wherein the at least one processor is further configured to cause the apparatus to:
determine whether one of the two or more unique participant identifiers is associated with the malfunctioning RF location tag by comparing a known number of participant-associated RF location tags to the second tag derived data.

an unassociated RF location tag configured to transmit blink data;
a plurality of associated RF location tags, each of the plurality of associated RF location tags associated with a participant identifier, and wherein each of the plurality of associated RF location tags are configured to transmit second blink data;
a plurality of receivers that are configured to:
receive the second blink data transmitted by the plurality of associated RF location tags and receive the blink data transmitted by the unassociated RF location tag;
determine tag derived data from the blink data; and
determine second tag derived data from the second blink data;
a receiver processing and distribution system configured to:
receive the tag derived data originating from the unassociated RF location tag;
determine unassociated tag location data for the unassociated RF location tag based on the received tag derived data;
receive the second tag derived data originating from the plurality of associated RF location tags;
determine associated tag location data for the plurality of associated RF location tags based on the received second tag derived data;
determine tag proximity location data for each of the plurality of associated RF location tags by comparing the unassociated tag location data to the associated tag location data;
determine a constrained set of associated RF location tags from the plurality of associated RF location tags based on determining whether the tag proximity location data for each of the plurality of associated RF location tags satisfies a proximity radius;
identify the participant identifier for each associated RF location tag of the constrained set of associated RF location tags;
in a circumstance where two or more unique participant identifiers are identified from the constrained set of associated RF location tags, determine whether one of the two or more unique participant identifiers is associated with a malfunctioning RF location tag;
in a circumstance where one of the two or more unique participant identifiers is associated with the malfunctioning RF location tag, output a tag participant correlator for associating the one of the two or more unique participant identifiers with the unassociated RF location tag.
11. The system of claim 10 , wherein the unassociated RF location tag comprises an ultra-wideband (UWB) transmitter.
12. The system of claim 11 , wherein the UWB transmitter is configured to transmit blink data comprising a plurality of time of arrival (TOA) timing pulses.
13. The system of claim 11 , wherein the UWB transmitter is configured to transmit an information packet comprising 112 bits.
