Voice quality measurements on a GSM network through free softwareMedidas de calidad de voz en una red GSM sobre software libreThis article presents the results obtained by measuring the quality parameters of a telecommunications network on GSM (Global System Mobile) in the DCS-1800 (Digital Cellular Service - 1800MHz) band; which is used in order to articulate a system of disaster relief in emergency situations, using a USRP (Universal Software Radio Peripheral) in conjunction with IP telephony system based on Asterisk. The USRP is responsible for emulating the operation of a BTS (Base Transceiver Station) performing the functions of a PBX (Private Branch Exchange). The measurements of network performance were made from three probabilistic parameters: GoS (Grade of Service), DCR (Dropped Call Rate) and MOS (Mean Opinion Score). Traffic was generated using an 8 terminals and choosing a GoS of 2% to 3.6 Erlang, this measurement was performed using probabilistic models of Erlang B. The network coverage was obtained using the Okumura-Hata model for both indoors and outdoors, without the use of amplifiers. The consumption of power in the system was also measured.En este artículo se presentan los resultados obtenidos al medir los parámetros de calidad de una red de telecomunicaciones sobre GSM (Global System Mobile) en la banda DCS-1800 (Digital Cellular Service - 1800MHz); utilizada con el objetivo de articular un sistema de atención de desastres en situaciones de emergencia, empleando un USRP (Universal Software Radio Peripheral) en conjunto con sistema de telefonía IP basado en Asterisk. El USRP se encarga de emular la operación de una BTS (Base Transceiver Station) ejecutando las funciones de un PBX (Private Branch Exchange). Las mediciones del desempeño de la red se realizaron a partir de tres parámetros probabilísticos: GoS (Grade of service), DCR (Dropped Call Rate) y MOS (Mean Opinion Score). Con el uso de 8 terminales y escogiendo un GoS del 2% se generó un tráfico de hasta 3,6 Erlang, esta medición se realizó empleando modelos probabilísticos de Erlang B. La cobertura de la red se obtuvo aplicando el modelo Okumura-Hata tanto para interiores como exteriores sin el uso de amplificadores, también se realizaron mediciones del consumo de potencia del sistema.Universidad Católica de Pereira2023-08-29T03:49:06Z2023-08-29T03:49:06Z2019-07-25Artículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/resource_type/c_2df8fbb1application/pdfhttps://revistas.ucp.edu.co/index.php/entrecienciaeingenieria/article/view/610http://hdl.handle.net/10785/13472Entre ciencia e ingeniería; Vol 7 No 14 (2013); 58-65Entre Ciencia e Ingeniería; Vol. 7 Núm. 14 (2013); 58-65Entre ciencia e ingeniería; v. 7 n. 14 (2013); 58-652539-41691909-8367spahttps://revistas.ucp.edu.co/index.php/entrecienciaeingenieria/article/view/610/616Derechos de autor 2019 Entre Ciencia e Ingenieríahttps://creativecommons.org/licenses/by-nc/4.0/deed.es_EShttps://creativecommons.org/licenses/by-nc/4.0/deed.es_ESinfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Gaona G., Elvis E.Cárdenas V., SantiagoMuskus R., Elkin G.oai:repositorio.ucp.edu.co:10785/134722025-01-27T23:59:16Z |
