With the availability of so many high-density, wire-speed Layer 3 switches, why would a network administrator choose to implement Virtual LANs (VLANs) today? The first (and most obvious) answer is cost. Layer 3 switches cost more than Layer 2 switches, and usually have less density, making them a natural fit at the very core of the network, leaving Layer 2 switches to handle Distribution Layer aggregation of wiring closet switches or Data Center switching. Layer 2 switches are often much simpler to implement, and can be implemented with less technical difficulty than routing. VLANs have also recently been reborn in Metropolitan Area Networks (MANs) based upon Ethernet technology as a Virtual Private Networking (VPN) solution. VLANs are now a required feature in any switched LAN solution. The increasing capacity and performance of switches has enabled users to dedicate switch ports to every user on the network, increasing the need for control over broadcast and multicasts throughout the network. To best understand VLANs, it is useful to study how networks evolved into needing VLANs.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.

Este articulo presenta el proceso de desarrollo de un módulo de capacitación en redes de área local (LAN: Local Area Networks), cuyos contenidos son de fácil entendimiento, que es posible tomarlo en un periodo muy corto de tiempo, que no depende directamente de un tutor para poderse realizar y que además tiene incluido un desarrollo práctico para la utilización del Laboratorio de Telemática de Fundación Universidad Autónoma de Colombia. Para poderlo realizar fue necesaria una indagación previa acerca del aprendizaje, la selección un plan temático, realizar la correspondiente recopilación bibliográfica para la creación de un marco teórico que fuese acorde con la teoría del aprendizaje y crear unas prácticas de laboratorio adecuadas que reforzaran el conocimiento adquirido. Como resultado se obtuvo un software didáctico que contiene todo el marco teórico distribuido en temáticas y prácticas de laboratorio que conjugan la parte teórica con la parte práctica.
