Measurement of building penetration into medium buildings at 900 and 1500 MHz

The propagation loss into ten medium-sized buildings in Schaumburg, IL, has been measured, At 900 MHz, the mean penetration loss in the lower enclosed floors at or near ground level was found to be 10.8 dB with a standard deviation of 5.8 dB, At 1500 MHz, penetration loss was found to be 10.2 dB, and the standard deviation was 5.6 dB, Data was also taken up to 12 doors (with a higher concentration of data on the first five floors) to show higher elevation trends in the penetration loss, The measured building penetration loss was combined with data from other references, and the slope of a best fit curve as a function of frequency is found to be -7.9 dB per decade.
