To the knowledge of the authors, studies making use of cellular network counters to analyse the impact
of solar originated radio waves on cellular telecommunication systems are a relatively unexplored
area. This dissertation examines interference of solar originated radio waves with the radio aspect of
terrestrial cellular telecommunications systems. A theoretical analysis was performed and real world
data were also obtained from a cellular network. Solar parameters that have a potential relationship to
noise generated on the cellular network were analysed, making use of the position of the sun relative
to the radiation patterns of antennas of cellular network equipment.
The most sensitive cellular networks are those based on the long-term evolution (LTE) standard;
radio bursts of as little as 10 solar flux units (SFU), though beyond the range of the equipment, are
theoretically detectable by it and bursts of 100 000 SFU have been shown to be capable of producing
noise levels of -88 dBm, 13 dBm above the thermal noise level at 300 K. A comparison between sun
incident hours and others, when the sun is not in direct line of sight of cellular basestation antennas,
reveals increased interference, though the cellular network data do not correlate well with solar radio
burst and X-ray flares, owing to lack of sample diversity and low granularity of telecommunications
data and lack of extreme solar events during the period. However, potential susceptibly to solar radio
interference exists, especially in the case of lower frequencies (900 MHz) in telecommunication bands
(900 2100 MHz) with high bandwidth (20 MHz) applications.
Na die wete van die skrywer is studies wat van sellulêrenetwerktellers gebruik maak om die impak van
radiogolwe van sonoorsprong op telekommunikasiestelsels te analiseer n relatief swak bestudeerde
veld. Hierdie verhandeling ondersoek die steurings wat radiogolwe van son-oorsprong het op die
radio-aspek van aard-sellulêre telekommunikasiestelsels. n Teoretiese analise is uitgevoer en gemete
is verkry van n sellul êre netwerk. Sonparameters wat potensieel n verband het met ruis op die
sellulêre netwerk opgewek is, is geanaliseer deur gebruik te maak van die posisie van die son relatief
tot die stralingspatrone van antennas van sellulêrenetwerktoerusting.
Die sensitiefste sellulêre netwerke is gebaseer op die langtermynevolusiestandaard (LTE); radiouitbarstings
van so min as 10 sonvloedeenhede (SFE) is waarneembaar met LTE en daar is bewys
dat uitbarstings van 100 000 SFE in staat is om ruisvlakke van -88 dBm te veroorsaak, 13 dBm bo die
termiese ruisvlak by 300 K. n Vergelyking tussen son-insidensie-ure en ander, wanneer die son nie
in direkte siglyn is nie, toon verhoogde inmenging, alhoewel die sellulêrenetwerkdata nie goed met
sonradio-uitbarstings en X-straal fakkels korreleer nie, te danke aan die lae granulariteit van telekommunikasiedata
en die afwesigheid van uiterste son-insidente gedurende die tydperk. Daar is nietemin
potensieel vatbaarheid vir son-radio-steurings, veral in die geval van laer frekwensies (900 MHz) in
telekommunikasiebande (900 2100 MHz) met hoë bandwydtetoepassing (20 MHz).
