The design, development and exploitation of Romeo, a last generation ROV capable of supporting robotics research on intelligent/autonomous vehicles and to execute scientific missions in very harsh environment, are presented. The system’s mechanical and communication design is discussed with respect to basic end-user requirements. A three Local Area Networks system architecture is proposed, and the main sub-systems connected to the surface (supervision), on-board and lab Ethernet LANs are described. The vehicle’s exploitation in scientific missions in harsh environment (Ross Sea in Antarctica), Internet-based mission control demonstrations and the integration with a multidisciplinary scientific and technological payload proved the capabilities of the proposed architecture in matching operational and research requirements.

Local area networks (LAN) are extremely popular in both the consumer and enterprise markets. The LAN has become ubiquitous throughout both of these markets as the Internet has grown in size and use, PCs have become readily available at an attractive price point, and high-speed broadband connections have become readily available. Yet, with all the usage of LANs for connecting computer equipment of all types, there is no standard, formal industry accepted definition for a local area network (Comer, 2006, 15). According to the Institute of Electrical and Electronics Engineers (IEEE), a local area network is describes as being “distinguished from other types of data networks in that they are optimized for a moderate-sized geographic area, such as a single office building, a warehouse, or a campus” (2001). Some definitions include a distinction concerning physical proximity (Palmer & Sinclair, 2003, 2), while others provide definitions based on topology, physical medium, or performance characteristics. Vendors, governing/standards bodies, and even network managers have yet their own definition of the exact meaning of what a local area network is and means. These definitions tend to use terminology loosely and allow the end user to determine actual meaning based on context and technologies used. The following discussion will give the reader the foundational information of LANs, including LAN addressing (both MAC and IP addressing), architecture, and protocols.

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.
