Abstract
This paper reports initial results of wireless data center (WDC) 60 GHz radio channel measurements in a real data center. A channel sounder based on a vector network analyzer is used to measure the channel transfer function. In addition, ray-tracing simulations are conducted to verify the measurements accuracy. Data post processing procedure is presented to derive the power delay profiles (PDP). PDPs are processed using a peak detection algorithm for quick clusters enumeration. Two measurement sets are considered, namely neighbor racks scenario set and cross aisle scenario set. It is found that ray-tracing simulations results show a reasonable agreement for both sets. Cluster number and path loss results exhibit a slight difference for the two sets. Moreover, path loss results of neighbor racks scenarios show a 3 dB better link budget compared to cross aisle scenarios.

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
