Solar radio emission as a disturbance of radiomobile networks

Abstract

Abstract This paper analyses the effects of solar radio emissions in the radiomobile context, for the first time leveraging massive European Telecommunications Standards Institute (ETSI) 3rd Generation Partnership Program (3GPP) Minimization of Drive Test (MDT) radio measures produced by 4G LTE (Long Term Evolution) terminals and by 4G LTE Base Station cells. A method to study solar noise effects starting from radiomobile 3GPP standard MDT measures is illustrated and correlated with the excellent 10.7 cm (2800 MHz) indicator of solar activity (National Research Council Canada). The effects of solar disturbance on the LTE radio access network for mobile services are analysed, and possible countermeasures are presented from the perspective of radiomobile network evolution to 5G and 6G.
