- Characterization of WiMAX propagation in microcellular and picocellular environmentsPublication . Barbiroli, Marina; Carciofi, Claudia; Degli-Esposti, Vittorio; Fuschini, Franco; Grazioso, Paolo; Guiducci, Doriana; Robalo, Daniel Luís Silveira; Velez, FernandoIn this paper different propagation models for coverage prediction of WiMAX microcellular and picocellular urban environments and for WiMAX indoor femtocells at 3.5 GHz are compared with experimental data. Results obtained for different urban and indoor environments show that statistical models are quite far from good agreement with experimental data while deterministic ray-tracing models provide appropriate prediction in all different complex analyzed environments.
