In this paper, the authors present a measurement campaign in a complex urban propagation scenario in downtown Patras, Greece, where a community-based metropolitan area Wi-Fi/WLAN operates at 2.4 GHz. Path losses and shadow fading characterization has been accomplished and the fine-tuning of respective models and distributions has taken place in order to compare empirical data with theoretical assumptions. These measurements have allowed for an extension of well-known path loss models from their established cellular-frequency operating range to the 2.4 GHz channel, and the relative mean error has been calculated for each model employed in their case study.
