Abstract

fetched live from OpenAlex

Aborda el estudio y la evaluación de los modelos de pérdida de \npropagación para los sistemas de comunicación móvil de Quinta Generación (5G) que están \nsiendo desarrollados por los principales proyectos y grupos de investigación a nivel mundial \ncomo el 3rd Generation Partnership Project (3GPP), International Mobile \nTelecommunications 2020 (IMT-2020) y Mobile and Wireless Communications Enablers for \nTwenty –Twenty Information Society (METIS). Los canales de radio objeto de este estudio \ncorresponden a entornos urbano-densos en las bandas 28 GHz y 73 GHz para caracterizar la \npropagación a gran escala. En ese sentido, se ha considerado como escenario de simulación \nrealista 3D al centro comercial Gamarra, el cual se encuentra en el distrito de La Victoria en \nLima-Perú, por presentar tales características. \nCabe mencionar que los modelos de pérdida de propagación a gran escala en bandas \nmilimétricas proporcionan una caracterización más compleja para el tipo de servicios y retos \nque 5G promete soportar a diferencia de los modelos en bandas inferiores a 6GHz. \nLa investigación se desarrolla bajo un enfoque cuantitativo e incluye fenómenos asociados \nal canal de radio con línea de vista (LOS) y sin línea de vista (NLOS), donde las pérdidas de \npropagación son obtenidas usando los modelos de canal. Finalmente, los resultados son \nevaluados en las bandas de frecuencia mencionadas partiendo de un escenario real.

Not 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.
