3 Contenido por planta N 1. Nombre de la planta Survey routes and access points Recorrido realizado en la planta N del edificio para hacer el estudio. N.1 Overall network health Tabla que contiene los posibles problemas globales que pueda tener la red en el gráfico posterior. Network health Lugares del edificio donde se puede realizar una conexión satisfactoria. Network issues Motivo por el cual no es posible establecer una conexión satisfactoria. Dicho gráfico hace referencia a la tabla que se explica en el primer apartado de esta sección, y cuya leyenda es la siguiente: o Rojo: Potencia de señal insuficiente. o Azul: Relación señal ruido demasiado baja. o Turquesa: Velocidad de conexión menor a 1 Mbps. o Amarillo: Número de punto de acceso insuficientes N.2 Coverage overlap and performance Data rate Velocidad máxima de conexión posible desde cada lugar del mapa. Number of APs (Access Points) Número de puntos de acceso visibles desde cada lugar del mapa. Signal strengh Potencia de señal o cobertura en cada lugar del mapa. El gráfico varía desde rojo hasta verde. El rojo significa mayor dificultad para conectarse, pero no por ello imposibilidad (ver sección N.1 apartado 2). Signal to noise ratio Relación que existe entre la señal wireless útil y el ruido existente en el medio, debe ser una relación positiva para permitir la transferencia de datos. En caso de que la señal esté cercana al nivel de ruido o cerca del mínimo exigido, es posible que se produzcan cortes en la conexión. Strongest Acces Points Punto de acceso que proporciona mayor cobertura en la zona. Cada zona está delimitada por colores. 1. N es el número de planta 1

4 N.3 Access Points Colocación aproximada de los puntos de acceso de la planta N. N.3.1 My Access Points Listado con los puntos de acceso mostrados en la sección N.3, las redes y el canal en que emite. Plantas estudiadas 1. Planta-1 2. Planta-2 3. Planta-3

6 1.1. Overall Network health Requirement criteria for Basic Connectivity signal strength at least dbm signal-to-noise ratio at least 5.0 db when data rate 1.0 Mbps data rate at least 1.0 Mbps number of access points at least 1 when signal strength at least dbm Network Health for Planta-1 Wi-Fi is typically built for a certain purpose or several purposes, such as VoIP, web browsing, or location tracking. With Network Health, you can, with a single visualization, display whether the network meets your requirements or not. 3

7 Network Issues for Planta-1 Network Issues complements Network Health by showing the requirement that is below the threshold level at each location. Whereas Network Health answers the question "Does it work?", Network Issues answers the question "If it doesn't work, why?". 4

8 1.2. Coverage, Overlap and Performance Data Rate for Planta-1 Data Rate is the highest possible speed (measured in megabits per second) at which the wireless client devices will be transmitting data. Typically the true data throughput is about half of the data rate or less. 5

9 Number of APs for Planta-1 Number of Access Points indicates the number of access points audible at each location. 6

10 Signal Strength for Planta-1 Signal Strength - sometimes called coverage - is the most basic requirement for a wireless network. As a general guideline, low signal strength means unreliable connections, and low data throughput. 7

11 Signal To Noise Ratio for Planta-1 Signal-To-Noise Ratio indicates how much the signal strength is stronger than the noise (co-channel interference). Signal must be stronger than noise (SNR greater than zero) for data transfer to be possible. If the signal is only barely stronger than noise, you may encounter occasional connection drop-offs. 8

12 Strongest Access Point for Planta-1 Strongest Access Point displays the access point that is the strongest per location. Strongest access point can thus be used for load balancing purposes, and to predict roaming patterns of client devices. 9
