dc.description.abstractOptimal planning for the integration of WiMAX (Worldwide Interoperability for Microwave Access) and Wi-Fi (Wireless Fidelity) technologies enables real technical conditions to make a hybrid Wi-Fi/WiMAX network available at the Health Sciences Faculty of University of Beira Interior, supporting nomadic applications like videoconference, voice over IP and communication of high resolution video/image. A simple wireless planning tool is designed and used in this optimal planning, which facilitates the design and implementation of Wi-Fi and WiMAX networks in indoor and outdoor environments. The tool gives useful information through quick coverage/capacity based procedures, as the output is the number and position of the APs (access points)/BSs (base stations) or an estimation of the total cost of implementation, based on data provided by different manufacturers. While planning methodologies are already stable for Wi-Fi, and propagation models have already been widely validated, the propagation models available for WiMAX still need to be tuned, which motivates the need to carry out propagation measurements. For IEEE 802.16-2004 networks operating at 3.5 GHz, by comparing the measurement results with the ones obtained using the modified Friis and the SUI (Stanford University Interim) models, it was concluded that, for a suburban area of Covilhã, Portugal, the use of the modified Friis model with a propagation exponent ~3 is more appropriate than the use of the SUI one, although for coverage distances between 275 and 475 m the SUI model (SUI-B and mainly SUI-C) may still be used. WiMAX cellular planning exercises are presented for the zone of Covilhã. Carrier-to-noise-plus-interference issues are discussed, and Geographic Information Systems are applied to determine the existence of line-of-sight in rural and sparse urban areas. One of the main conclusions arising from this work is the strong need of using sectorial antennas to guarantee an adequate coverage and interference mitigation for several terrain types and environments, including hilly terrain.pt_PT
