Design and Planning of IEEE 802.16 Networks

This paper addresses aspects of design of WiMAX wireless networks to establish a point-to-point, PTP, link with Alvarion BreezeNET B equipment, from the Health Sciences Faculty of University of Beira Interior to Hospital Sousa Martins (Guarda), and also presents a field trial with pre-WiMAX PTP equipment. The design of the link with relays had into consideration the carrier to noise ratio, C/N, and the minimum carrier to noise ratio with fading, C/Nminjad. From the dimensioning process, with gamma = 2, for the second clause, the three types of modulations (low to high order ones) can be used. Field trials results are similar to the ones extracted from the theoretical model. Cellular WiMAX planning and tests were also addressed and there is a need of using sectorial antennas to optimize coverage and interference.
