Abstract

This paper presents a propagation model for prediction of path loss and performance parameters (throughput and frame loss) on OFDM-based networks. For this study, measurements on a 5.8 GHz Wimax network were carried out. The proposed model parameters have been adjusted by LS (Least Squares) optimization, using measured data as reference. The results show that the proposed model has a good agreement with the measurements. Futures works can consider an adjustment for a set of frequencies. For this purpose, extensive measurements campaigns will be carried out.
