AbsfracfThis paper presents the results of average and impulsive noise measurements inside several office buildings and retail stores. The noise measurement system operated at 918 MHz, 2.44 GHz, and 4 GHz with a nominal 40 MHz 3 dB RF bandwidth. Omnidirectional and directional antennas were used to investigate the characteristics and sources of RF noise in(More)
This paper presents results of wide-band path loss and delay spread measurements for five representative microcelMar environments in the San Francisco Bay area at 1900 MHz. Measurements were made with a wide-band channel sounder using a 100-ns probing pulse. Base station antenna heights of 3.7 m, 8.5 m, and 13.3 m were tested with a mobile receiver antenna(More)
This paper studies the impact of surrounding buildings on path loss and multipath delay spread for Personal Communication Services (PCS) operating inside of buildings. Measurements conducted inside three large office buildings in the San Francisco Bay area provide an extensive database for propagation models at 915 MHz and 1900 Wlz, and show variability in(More)
This paper presents results of wide band path loss and delay spread measurements for two representative microcellular environments in the San Francisco Bay area in the 1900 MHz band. The results presented in this paper provide insight into the statistical distributions of measured path loss by showing the validity of a double regression model with a break(More)
