Resumo(s)
This work intends to develop a WiMax (Worldwide Interoperability for Microwave Access) point-to-multipoint wireless network that includes all the district of Covilhã, and particularly the urban area of the city in detail, with the objective to guarantee a point-to-multipoint connection from the Health Science Faculty of the University of Beira Interior (HSF/UBI) / Hospital Pêro da Covilhã to all urban area of the centre of the city. The cellular planning of this WiMax mobile network was done having in account aspects related with the carrier-to-noise ratio and carrier-to-interference ratio, concluding that is necessary to consider a cellular structure with coverage distances of 3 km and sectorisation is needed to create a high capacity wireless network in the urban area of Covilhã. Because this zone is very hilly, the choice of the location for base stations is essential; one used the potentialities of the GIS (Geographic Information Systems) tools to optimize the line of sight coverage and, simultaneously, reduce the propagation exponent. A new mobile IP architecture for Wi-Fi/WiMax interoperability is being conceived, developed and implemented based in Media Independent Handover.
