Abstract: Building penetration measurements were taken simultaneously at three potential Personal Communications Services (PCS) frequencies: 912, 1920, and 5990 MHz. The continuous wave (CW) measurement system employed a fixed outdoor transmitter and a mobile indoor receiver. The goal was to quantify building penetration losses at these frequencies to determine the viability of indoor coverage using street microcells and base antenna heights below the roof level of surrounding buildings. Eleven different buildings representing typical residential and high–rise office building environments were used for the measurements. Vertically polarized transmit and receive antennas were used for all measurements. Statistical analyses of the data include mean building attenuation losses, standard deviations, cumulative probability distribution functions, and correlation coefficients. The analyses were used to characterize propagation effects and provide a comparison between three frequencies, two cell environments, and two transmission paths
