Combining Leak feeder cable and Antenna to support Mobile network in underground mine environment
Bibliographic record
Abstract
This paper reports the measurements of a hybrid radiating LTE base-station (BS) based on Software Defined Radio (SDR) platform. The hybrid radiating elements consisted of a hybrid architecture of 2 antennas and a Leaky Feeder (LF) cable to support LTE technology operating in Frequency Division Duplex (FDD) on 850Mhz radio band. All the measurements were made in a former underground gold mine. The used LF cable aimed to enhance the radio signal propagation, particularly in Non-Line Of Sight (NLOS) areas where signal propagation has difficulty to reach the destination. Also, LF cable avoided increasing the number of deployed BSs to deal with NLOS areas and reduced the transmission power of the mobile user equipment (UE) without losing the quality of service(QoS).

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
