Abstract

This letter presents the experimental characterization and modeling of the radio channel for outdoor-indoor communications, within the framework of broadband fixed wireless access (BFWA) systems. Five models based on tapped delay lines have been proposed. These models provide a good fit of the measured rms delay spread. The time delay values are considerably lower than the typical values for outdoor channels in urban and suburban environments. In quasi-line-of-sight (LOS) situations, it is not necessary to distinguish between open and closed environments, while this is necessary in the case of NLOS and hard-NLOS situations
