Abstract
At the advent of 5G mobile communication systems, reliable and fast wireless communications for the user equipments onboard a train is crucial. One of the desirable cost-effective solutions is to use dedicated antennas installed along the train tracks. This is known as so-called antenna corridor. Usually, the antenna corridor solution is used in combination with an antenna on the roof-top of the wagon and a repeater plus one (or few) leaky feeder cables inside the compartment. Nevertheless, for certain reasons, it is more desirable to receive signals into the wagon directly through its window panes. The latter causes extra losses due to the wide (i.e., ≈ 90°) arrival angles between incoming waves and the window panes’ surface vector. In this paper, we propose to use a passive reflector which is installed alongside the railway track to forward the incoming waves towards the wagon. We use a simple 45° slanted plane reflector and quantify the reduction it yields in pathloss between an arbitrary transmit antenna and an ideal dual-port dual-polarised isotropic antenna within a selected wagon.

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
