Aplicação de modelos de predição de programação a redes de computadores sem fio.

Abstract

In this analyse is showed the prediction models for propagation loss for a wireless computer network, working in urban area. Using a 802.11b wireless equipments adapted for a function in a outdoor urban environments. For this, standart equipments antennas are changed for external antennas installed in the user edification rooftop connected by appropriate cable and connectors. Then, power signal level received, user antenna height and distance between clients and base station was measured. These parameters are used in propagations lost equations and then graphics are plotted for decribed situation. At last, the data information's and graphics are plotted together in a power versus distance graphic to compare results. At last, results are analysed to show which models are good for comportamental description for power lost with distance for the situation describred here.
