Abstract: Radiowave propagation measurements made in an urban area of Denver, Colorado, are described. Wideband, impulse response measurements were made at 4 carrier frequencies from 420 MHz to 5750 MHz. Basic transmission loss slope and delay spread statistics are used to characterize propagation conditions. By analyzing these results versus carrier frequency the relative propagation impairments for communication systems at 430, 1350, 2260 and 5750 MHz are compared. It was found that the path loss slope increased on average by 11 dB/decade and the delay spread decreased from 33% to 65% over the decade of frequencies measured.

Keywords: impulse response; basic transmission loss; radio wave propagation; delay spread; urban environment; path loss
