〈WiMAX Near LOS Measurements and Comparison with Propagation Models〉

Worldwide Interoperability for Microwave Access (WiMAX), as an open standard IEEE 802.16, offers a low cost wireless broadband access suitable for the emerging countries in the Latin America market. This paper analyzes the challenges imposed by the RF propagation environment, through field measurements, when using high frequencies such as 3.5 GHz, to a non line of sight (NLOS) WiMAX transmission condition, and suggests the importance of understanding the Near LOS conditions, as the transition region between LOS and NLOS, comparing with existing propagation models. The measurements where carried out in Brazil and in Mexico during 2008, and portrait the WiMAX propagation channel in typical suburban environment in Latin America.
