Locating RFID-Tagged Objects: Last Seen, Zones, and Coordinates

Updated September 11, 2026

Purpose: Compare asset-location results with independently recorded reference information. This worksheet sets no universal accuracy or safety threshold.
Instructions: Define thresholds before testing. Use the same coordinate frame and units for any coordinate comparison. Keep every scheduled check, including missing and stale results. Use synthetic identifiers in shared examples.

Task / asset type / intended user / location granularity:
System and tag models / firmware / configuration:
Tag position / battery status where relevant:
Reference method / reference uncertainty / coordinate frame / units:
Required freshness (seconds) / error or room criterion / task time target:
Test area / route or check schedule / conditions:

Copy this block for EACH scheduled check:
Test ID / reference timestamp and time zone / true room or coordinates:
System observation timestamp / receipt timestamp / displayed value:
Freshness in seconds / room match or calculated positional error:
Outcome: fresh correct / fresh wrong / stale / missing:
Asset found? Search time in seconds / manual effort / exception:

Summary: total scheduled checks / fresh correct / fresh wrong / stale / missing:
Fresh-correct coverage = fresh-correct checks / ALL scheduled checks x 100.
Define any accuracy denominator explicitly and report missing/stale counts separately.
Invented arithmetic example: 18 fresh correct, 0 fresh wrong, 0 stale, 2 missing across 20 checks gives 90% fresh-correct coverage and 100% correct among the 18 returned results.

Boundary-crossing and stationary-stock results:
Outage / degraded coverage / recovery tests:
Attachment/reassignment and battery-service owner:
Accepted conditions / unresolved issues / retest trigger:
