    Future wireless local area networks (WLANs) are expected to serve thousands of users in diverse environments. To address the new challenges that WLANs will face, and to overcome the limitations that previous IEEE standards introduced, a new IEEE 802.11 amendment is under development. IEEE 802.11ax aims to enhance spectrum efficiency in a dense deployment; hence system throughput improves. Dynamic Sensitivity Control (DSC) and BSS Color are the main schemes under consideration in IEEE 802.11ax for improving spectrum efficiency In this paper, we evaluate DSC and BSS Color schemes when physical layer capture (PLC) is modelled. PLC refers to the case that a receiver successfully decodes the stronger frame when collision occurs. It is shown, that PLC could potentially lead to fairness issues and higher throughput in specific cases. We study PLC in a small and large scale scenario, and show that PLC could also improve fairness in specific scenarios

    Conference proceedings info: ICICT 2023: 2023 The 6th International Conference on Information and Computer Technologies Raleigh, HI, United States, March 24-26, 2023 Pages 529-542We provide a model for systematic implementation of telemedicine within a large evaluation center for COVID-19 in the area of Baja California, Mexico. Our model is based on human-centric design factors and cross disciplinary collaborations for scalable data-driven enablement of smartphone, cellular, and video Teleconsul-tation technologies to link hospitals, clinics, and emergency medical services for point-of-care assessments of COVID testing, and for subsequent treatment and quar-antine decisions. A multidisciplinary team was rapidly created, in cooperation with different institutions, including: the Autonomous University of Baja California, the Ministry of Health, the Command, Communication and Computer Control Center of the Ministry of the State of Baja California (C4), Colleges of Medicine, and the College of Psychologists. Our objective is to provide information to the public and to evaluate COVID-19 in real time and to track, regional, municipal, and state-wide data in real time that informs supply chains and resource allocation with the anticipation of a surge in COVID-19 cases. RESUMEN Proporcionamos un modelo para la implementaci贸n sistem谩tica de la telemedicina dentro de un gran centro de evaluaci贸n de COVID-19 en el 谩rea de Baja California, M茅xico. Nuestro modelo se basa en factores de dise帽o centrados en el ser humano y colaboraciones interdisciplinarias para la habilitaci贸n escalable basada en datos de tecnolog铆as de teleconsulta de tel茅fonos inteligentes, celulares y video para vincular hospitales, cl铆nicas y servicios m茅dicos de emergencia para evaluaciones de COVID en el punto de atenci贸n. pruebas, y para el tratamiento posterior y decisiones de cuarentena. R谩pidamente se cre贸 un equipo multidisciplinario, en cooperaci贸n con diferentes instituciones, entre ellas: la Universidad Aut贸noma de Baja California, la Secretar铆a de Salud, el Centro de Comando, Comunicaciones y Control Inform谩tico. de la Secretar铆a del Estado de Baja California (C4), Facultades de Medicina y Colegio de Psic贸logos. Nuestro objetivo es proporcionar informaci贸n al p煤blico y evaluar COVID-19 en tiempo real y rastrear datos regionales, municipales y estatales en tiempo real que informan las cadenas de suministro y la asignaci贸n de recursos con la anticipaci贸n de un aumento de COVID-19. 19 casos.ICICT 2023: 2023 The 6th International Conference on Information and Computer Technologieshttps://doi.org/10.1007/978-981-99-3236-
