PLANNING OF OUTDOOR BROADBAND FIXED WIRELESS ACCESS SYSTEMS OPERATING AT 10-66 GHZ BAND
The development of outdoor fixed broadband wireless access (BWA)systems operating at 10-66 GHz frequency requires a carefully planning in orderto maximizing the use of the bandwidth, maximizing network capacity, assuringminimum requirements of availability and minimizing costs in an environmentand in a frequency band where the propagation of electromagnetic waves aresubjected to specific issues. This work presents the aspects related to thedevelopment of this kind of system in a point-to-multipoint architecturestandardized by the IEEE 802.16 recommendation. Models to predict coverage,estimate differential rain attenuation and predict rain attenuation considering theun-homogeneity of the rain in horizontal plane. The effects of interference in thesystem performance are discussed with some examples of cell planning. The mainaspects of capacity planning are described and techniques to maximize capacityare presented. In order to helping the planners in practical situations theinformation are organized in a proposal of planning methodology that includestechnical, business and marketing issues.
