RFID read map: INVENTED teaching data
Guide: https://yenra.com/rf-id/visualization.html

No hardware was measured. Each tested coordinate has ten two-second trials. Coordinate origin is an illustrative floor-grid corner; x/y units are metres. Target height, orientation and reader settings are held constant in this fictional experiment. Out-of-zone test tags stay fixed. This dataset specifies outcomes, not a RF propagation model.

SUMMARY CSV: x_m/y_m = known test coordinates; trials = number of windows; target_success_trials = windows with the intended target seen at least once; unwanted_read_trials = windows with at least one known outside tag seen. A trial can count toward both. At (1,2), trials=0, counts blank, because access was blocked; this is not zero success.

TRIAL CSV: one row per tested window; target_seen and any_out_of_zone_tag_seen are 0/1 indicators. trial is sequential within a coordinate; window_seconds is 2. Repeated tag reports never increase an indicator above 1.

To reproduce: group trial rows by x_m/y_m, count rows and sum the two indicator columns. Divide each sum by the number of rows for that position and multiply by 100. Add the explicitly untested grid point from the summary. Keep all untested values absent from rate calculations.

Expected totals: 80 trials, 48 target-success trials (60%), 9 unwanted-read trials (11.25%). Counts describe this grid only, not general system performance.

For real work add raw tag IDs, reader/antenna/model/firmware, settings, coordinate origin, target construction/surface, height/orientation, timestamp basis, reset procedure and reasons for exclusions in a controlled test record.
