Previously, in NPM Javascript to compute Attenuation By Atmospheric Gases ( ITU-R P.676-9), the Javascript Library is published on NPM that computes the attenuation (unit of dB loss per km) given the frequency, temperature and the atmospheric pressure (unit of hPa). with the latest commits to the package AttenuationByAtmosphericGases version 2.0.0, the library allows also Continue Reading »
ITU-R P.676-9 is proposed by International Telecommunication Union that recommends the Attenuation by atmospheric gases which are influenced by frequency, temperature and atmospheric pressure (unit of hpa). In case of temperature is not known, the mean temperature can be used, where this can be found in document ITU-R P.1510. In here, we know that the Continue Reading »
With 5G networks, there are a few potential challenges for the channel/propagation modelling due to the radiowave behavior and characteristics under 5G frequency bands. Weather The radiowave propagation for millimeter wave for 5G networks is likely to be affected by the weathers. The raining, snowy and windy days may influence the attenuation depending on how Continue Reading »
