NTIA Report TR-04-407Relative Propagation Impairments Between 430 MHz and 5750 MHz for Mobile Communication Systems in Urban EnvironmentsDecember 2003Peter Papazian, Michael Cotton |

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. |
