- W2146388675 abstract "Path-loss in urban area small and microcell environments is discussed. Results from dual-frequency measurements performed in urban areas at 955 MHz and 1845 MHz are presented. The mean difference in path loss between the two frequencies was found to be 10 dB, whereas the free-space loss is only 6 dB. The shadow-fading at the two frequencies was highly correlated. Therefore much of the experience from the 900-MHz band can be used for planning of new cellular systems in the 1800-2000-MHz band. M. Hata's (1980) prediction model was fitted to the data at both frequencies, but predicted too-low path loss at 1845 MHz. A modified Hata prediction model is proposed for use in the frequency range 1500 to 2000 MHz. The effect of low base station antenna heights is also discussed.< <ETX xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>></ETX>" @default.
