Abstract
By measuring the time-of-flight (TOF) of ultra-wide bandwidth (UWB) signals, the distance between two transceivers can be obtained. A two-way ranging method has been considered because one-way ranging is susceptible to the network synchronization. However offsets between the crystal oscillators in different transceivers can generate frequency errors, which will influence the estimated round trip time of the signals. Temporal errors on the order of nanoseconds will eventually reduce distance errors on the order of decimeters. This paper presents a novel asymmetric double sided two-way ranging method, which enhances the tolerance for crystal offsets compared with the conventional two-way ranging method It also reduces the detection time of the symmetric double sided two-way ranging method by half.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
