Site-specific validation of ITU indoor path loss model at 2.4 GHz

This paper presents a site-specific validation of the ITU indoor path loss model at 2.4 GHz. Based on measurements acquired in a recent experiment for a WLAN indoor office environment, we are able to accomplish a numerical adjustment of the Site-general ITU model to the specific measured data that reflect the intrinsic characteristics of the complex indoor topology, thus validating the Site-Specific ITU model at 2.4 GHz. For the first time, we are in position to provide values for the model´s parameters that concern specifically this frequency band, which is of utmost importance for wireless networks, mostly for WLAN channels. This marks a major step towards an even greater degree of precision and reliability in the usage of indoor RF models for link budget design in modern wireless communications.
