A procedure to extract rain attenuation from MEO satellite signals is presented in the framework of MEKaP (MEO Ka-band Propagation), a European Space Agency (ESA) funded project. This task involves removing received signal effects induced by presence gases along path, change distance and variation onboard antenna gain as perceived at ground station. To this aim, ancillary data are exploited, such ephemeris, ERA5 products some basic information on antenna. Some preliminary examples derived...
A frequency scaling (FS) model is presented for the prediction of rain-induced attenuation affecting a short terrestrial link operating at D band, to be potentially used as backhaul in future sixth generation (6G) networks. The methodology, which aims estimating rain target higher from measurements collected lower requires input local time series rate and defines ratio function specific attenuations two frequencies. Data long-term propagation study, conducted collaboration between...
The path reduction factor (PRF), a key element of semi-empirical rain attenuation statistics prediction models, is investigated to shed some light on its value for links shorter than 1 km. PRF here calculated from simulations underpinned by the use Enhanced Synthetic Storm Technique (E-SST) take into account rate spatial distribution along path. This novel approach, in contrast with more customary one inferring model measurements, offers advantage avoiding considering any unwanted additional...
