Microwave link rain fade
Rain fade is not limited to satellite uplinks or downlinks, as it can also affect terrestrial point-to-point microwave links (those on the earth's surface). Rain fade is usually estimated experimentally and also can be calculated theoretically using scattering theory of raindrops. Meer weergeven Rain fade refers primarily to the absorption of a microwave radio frequency (RF) signal by atmospheric rain, snow, or ice, and losses which are especially prevalent at frequencies above 11 GHz. It also refers to the … Meer weergeven It is possible to extrapolate the cumulative attenuation distribution at a given location by using the CCIR interpolation formula: Ap = A001 0.12 p . where Ap is the attenuation in dB exceeded for a p percentage of the time and A001 is … Meer weergeven • Fresnel zone • Diversity scheme • Drop size distribution (DSD) • IndoStar-1, first direct broadcasting satellite that used S-Band that can efficiently reduce rain fade Meer weergeven The simplest way to compensate the rain fade effect in satellite communications is to increase the transmission power: this dynamic … Meer weergeven In terrestrial point to point microwave systems ranging from 11 GHz to 80 GHz, a parallel backup link can be installed alongside a … Meer weergeven According to the ITU-R, rain attenuation statistics can be scaled in frequency in the range 7 to 55 GHz by the formula where and f is the … Meer weergeven http://da.fmuser.net/content/?7721.html
