Abstract
This paper compares the various temporal characteristics of radio channels for a broad range of frequencies, including 2.45, 5.25, 29 and 60 GHz, in various foliage and weather conditions. A substantial number of data points, in excess of 1.9 billions at 500 samples per second (equivalent to 45 days), was collected and analyzed for three particular types of channels: foliated deciduous trees, non foliated deciduous trees and coniferous trees. The radio channels are statistically analyzed and the resulting PDFs (probability density functions) and CDFs (cumulated density functions) are compared against existing models. Furthermore, wind speeds and rain precipitation are correlated with the power samples to consider RF propagation dependencies. Second order statistics are derived including level crossing rate (LCR) and average facie duration (AFD). The power profile is analyzed for spectral components. The frequency characteristics of the RF propagation channel are evaluated. Finally, channel-specific RF propagation attributes are presented.

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
