Modelo de afectación de calidad de servicio en redes Wi-Fi en coexistencia con redes LTE en banda no licenciada

Abstract

Initiatives for LTE transmission in the 5 GHz unlicensed band are subject of discussion as could represent an increase in terms of capacity to mobile LTE operators of around 500 MHz but also a potential degradation in terms of quality of service of technologies operating in the 5 GHz unlicensed band such as Wi- Fi, with presence in the market for more than 15 years as one the fastest growing wireless technologies. In this document, quality of service of Wi-Fi network in coexistence with LTE network over unlicensed band is evaluated through quantitative affectation index for network throughput. Coexistence was simulated by using NS-3 software following 3GPP-TR069 recommendations. In all cases, network throughput degradation was found over Wi-Fi operator during its coexistence with LTE operator.
