Resumen Voz sobre IP, VoIP, es uno de los servicios con mayor desarrollo bajo plataformas inalámbricas; actualmente se ha iniciado su implementación como alternativa frente a la PSTN (red pública conmutada). El interés por VoIP radica en su relación costo-beneficio, ya que las organizaciones pueden utilizar la misma plataforma de su red de datos para transmitir voz. Por lo anterior, es importante que la organización tenga claro que, para garantizar el buen funcionamiento del servicio de VoIP, es decir para ofrecer QoS, se debe realizar la medición de parámetros que afectan la calidad del servicio como lo son: el retardo, la variación del retardo, el ancho de banda y la pérdida de paquetes. Este artículo analiza y valida los parámetros de QoS necesarios para garantizar el buen funcionamiento del servicio de VoIP sobre la red inalámbrica del campus de la Universidad Icesi. Se realizan pruebas en diferentes escenarios para mostrar que no solo factores como el retardo, y su variación, influyen en la calidad de servicio, sino que también la intensidad de la señal que recibe el cliente desde los puntos de acceso.Palabras Clave: Voz sobre IP, Calidad de servicio, Pérdida de paquetes, Retardo, Variación del Retardo, Intensidad de Señal. Abstract VoIP is one of the services that has been developing over under this type of wireless platforms and today has begun to implement as an alternative to the PSTN (Public Switched Telephone Network). The interest in VoIP is its cost-benefit ratio, and that organizations can use the same platform for their data network to transmit voice. Therefore it is important that the organization is clear that to ensure the smooth operation of the VoIP service, ie provide QoS, you must perform the measurement of parameters that affect the quality of service such as: delay, jitter, bandwidth, packet loss. In this paper we analyze and validate the QoS parameters needed to ensure the smooth operation of VoIP over wireless network on the Icesi University campus. We performed a series of tests in different scenarios to show that not only factors such as delay and jitter influencing the quality of service, but also the client signal strength received from of the AP (Access Point).Keywords: Voice over IP, Quality of service, Packet Loss, Delay, Delay variation, signal intensity.

Abstract The paper presents a new concept, Usability Monitoring, and applies it for situational awareness applications in military Command, Control, Communication, Computers, Intelligence, Surveillance and Reconnaissance systems (C4ISR). Usability Monitoring means taking measurements of technical Quality of Service (QoS) parameters in end systems and comparing them to target values of reference cases. The concept differs from QoS monitoring in the goal and in the placement of measurement points: In QoS monitoring the goal is to verify that the network provides the promised service quality in the user system - network interface. QoS monitoring does not capture the actual end user experience, which is influenced also by the end system, and therefore it does not directly correspond to the service quality that a user sees. Usability Monitoring has exactly this goal. The Observe-Orient-Decide-Act-Loop (OODA) is a decision making concept that is widely used in the network-centric approach and it emphasizes fast decision making. The presented model for Usability Monitoring is based on the OODA-loop. It includes QoS measurements not only in the Act-phase, i.e., can the user perform the actions s/he wants or are there delays and losses that make the system less usable, but also in the Observe-phase, i.e., does the user get the information s/he subscribes to, and in the Orient-phase, i.e., does the user get confusing information and cannot orient, and also the Decide-phase, i.e. is the user able to make right decisions based on the previous steps. The measured technical QoS parameters are connected to user experience by Mean of Score (MOS) functions that are obtained by usability tests. A case study for partially evaluating the Usability Monitoring concept is from MNE5 MSA (Multinational Experimentation 5, Maritime Situational Awareness) Experimentation Event 3 that was conducted in partnership with the Navy Command Finland, Naval Warfare Centre of Sweden and NATO Allied Command Transformation (ACT) and the Singaporean Armed Forces (SAF) Future Systems Directorate. In the MNE5 MSA experimentation we were able to monitor end user experience, how the user sees the services and is able to work with the current tools and capabilities. In this article we describe how Usability Monitoring was addressed in the MNE5 MSA case study: meters for Usability Monitoring were selected and we investigated what aspects of usability affect the phases of the OODA-loop.
