For the purpose of this final work a wireless local area network simulation was made in a closed laboratory on the Department of electronics and information technology. The theme of the final work is „Prototype of a wireless local area network for a sports field“. Simulation was made with the resources that were available at the Department of electronics and information technology and with additional resources which were generously borrowed by mentor, senior lecturer Listeš Tatjana, senior lecturer Pezelj Alen and professor Kovačević Tonko. Since the simulated network is actually a prototype of a wireless local area network for a sports field, efforts have been made in the simulation to use equipment that would be used in practice when building the network. The assembly components used in prototyping were: copper cabels, fiber cabels, media converters, wireless access points, switches, router and personal computers. The functionality of this simulation is to get as close as possible to the wireless local area network, which in reality should be built for networking projects of smaller open locations. Goal of this prototype is that the wireless local area network is working in order with opportunities and conditions which are founded in a laboratory on the Department of electronics and information technology. Simulation in the easy way actually tries to explain how hard would it be in the real world to develop this project without real resources and financial assets.
