Experimental Coverage Measurements on a Commercial 5G Network in the 28 GHz mm-Wave Band
Bibliographic record
Abstract
This paper presents the coverage measurements and path loss results of a 5G indoor and outdoor signal within the 5G Laboratory located in the Department of Electrical Engineering of the University of Chile. An Ericsson AIR 5121 antenna and commercial base station that is in a fixed position inside the laboratory and a 5G router equipment (5G NR mmWave Mobile Hotspot) are used to perform measurements in the 28 GHz frequency band. Both Line of Sight (LoS) indoor and Non-Line of Sight (NLoS) scenarios were considered within the laboratory and in a hall next to the it and Line of Sight (LoS) outdoor the laboratory. The measurement results show acceptable data rates in DL and UL, however a deviation of 20 dB to 30 dB with respect to the 3GPP TR 38.901, METIS and NYU model. These results are expected to be important to review the coverage behavior of a commercial 5G network at the 28 GHz band millimeter wave frequency.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
