Download or read book Estimates of Satellite EHF Communication Outages Due to Attenuation by Rain written by Paul Tattelman and published by . This book was released on 1987 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides estimates of outage frequencies, durations, and probabilities at eight United States locations for a satellite EHF communication system employing a frequency of 30 GHz and a fade margin of 15 dB. Ten years of 1-min rain rates at each location were used in conjunction with a attenuation model to make the estimates. One-min rates are recognized as most practical for these calculations, but are ordinarily unreadable from original recordings is described. Analyses of the 1-min rain rates and outage estimates for elevation angles of 10 deg, 30 deg, 50 deg, and 70 deg are presented. Keywords include: Rainfall, Attenuation, EHF communications, and Satellite communications.

Download or read book New Rain Rate Analyses to Assess Rain Attenuation on Satellite EHF Communications written by and published by . This book was released on 1989 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimates are provided on the frequency of occurrence, duration and probability of satellite EHF communication outages due to attenuation by rain. These can be used to determine optimum frequencies, power levels and the need for space diversity of terminals or other alternatives to maintain reliable communications. Ten years of 1 min rain rates at each of 12 U.S. cities were used in conjunction with an attenuation model to quantify communication outages at locations representing a variety of climatic regimes. Analysis of the 1 min rain rates and outage estimates at 10, 30 and 45 GHz for elevation angles of 10, 30, 50, and 70 are presented. Keywords: Satellite communications; Extremely high frequency; Radio signals; Alternatives; Rain.
Download or read book Effects of Rain Attenuation on Satellite EHF Communications in the United States written by Paul Tattelman and published by . This book was released on 1989 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: One-minute rain rate data over a 10-year period-of-record at each of 41 locations in the contiguous U.S., and for a 6 1/2-year period-of-record at 1 location in Puerto Rico, were extracted from original weighing raingage recordings. The data were analyzed to determine monthly, seasonal, and annual rain-rate frequencies, durations, and probabilities at locations representing a large variety of climatic rainfall regimes. These analyses are particularly useful for estimating EHF (Extremely High Frequency) communication outages due to the increasing effects of attenuation caused by rain at frequencies above 10 GHz. An attenuation model was used to estimate the effects of rain attenuation at all 42 locations. Analyses of the 1-min rain rates, and outage estimates for various frequencies and propagation-path elevation angles are presented.
