Abstract :
Results of measurements at 917 MHz, performed mainly in two large buildings of similar design, are presented, and by an empirical attenuation model based on estimates of transmission, refraction, and diffraction phenomena occurring in the transmission path is elaborated. The modeling fits the data with ±2 dB for 68% of the 729 measurements, the standard deviation between measurements and prediction being slightly less than 3 dB
