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

摘要

The propagation loss into ten medium-sized buildings innSchaumburg, IL, has been measured. At 900 MHz, the mean penetration lossnin the lower enclosed floors at or near ground level was found to ben10.8 dB with a standard deviation of 5.8 dB. At 1500 MHz, penetrationnloss was found to be 10.2 dB, and the standard deviation was 5.6 dB.nData was also taken up to 12 floors (with a higher concentration of datanon the first five floors) to show higher elevation trends in thenpenetration loss. The measured building penetration loss was combinednwith data from other references, and the slope of a best fit curve as anfunction of frequency is found to be -7.9 dB per decade
