    Rain Dependant Site Diversity Outage Improvements Statistics for Systems Working in Millimeter-Wave Band

  • Original language description

    The signal propagation at the frequencies above 10 GHz suffers from significant attenuation due to rain, which in case of point-to-multipoint systems is unlikely to be compensated for by available fade margin alone. For this reason and especially thanksto the non-uniform spatial distribution of the rain rate, it is suitable to utilize site diversity concept during planning of point-to-multipoint wireless systems. A database of radar data for numerous types of rain events has been established to enablesystem testing under different conditions. Outage improvement was studied using space-time simulations of point-to-multipoint systems in a specific area under a specific rain conditions. System outage improvement probability was derived as a straightforward function of the rain fade margin, angle separation and distances of main and diversity hubs. Some of the simulation results at 42 GHz and corresponding outage improvement probability using the site diversity are presented as well.

    Statistiky zlepšení výpadků systémů pracujících v milimetrových pásmech použitím prostorové diverzity během dešťových událostí

  • Czech description

    Spolehlivost systémů pracujících v kmitočtových pásmech vyšších než 10 GHz bývá velmi ovlivněna meteorologickou. Na základě časoprostorových simulací byla provedena analýza zlepšení výpadků systémů typu point-to-multipoint pracujících v milimetrových pásmech pro specifické oblasti a za daných dešťových podmínek.
