Korrelation av lokala väderförhållanden och prestanda för mobilnätverk (Swedish)
Abstract [en]

In this thesis, the relationships between local weather and the performance of a cellular telecommunications network were investigated by means of data analysis. Models of the average daily cycles in the data were developed accounting for cyclic behaviour and seasonal trends. Several different analysis methods were then performed on data measuring deviations from these average cycles. The methods used were multiple linear regression, partial least squares regression, calculation of Spearman's correlation coefficients, and regression by artificial neural networks.

Some of the results indicate that the number of calls being attempted in the network is related to the local weather conditions. Additionally, small indications were found that the percentage of failed calls in the network was related to the amount of precipitation. These findings could potentially be valuable for network operators.

Abstract [sv]

I detta examensarbete undersöktes samband mellan lokala väderförhållanden och indikatorer på nätverksprestanda för ett mobilnätverk. Undersökningen genomfördes med hjälp av dataanalys. Modeller för den genomsnittliga dagliga variationen i de undersökta parametrarna utvecklades där hänsyn togs till cykliska trender och säsongsberoende. Ett flertal analysmetoder tillämpades sedan på data som mätte avvikelser från de genomsnittliga variationerna. Metoderna som användes var linjär regression, ’partial least squares’ regression, uträkning av Spearmans rangkorrelation, och regression med hjälp av artificiella neuronnät.

Resultaten indikerade att antalet samtal som försökte kopplas upp i nätverket influerades av väderförhållandena. Dessutom kunde små indikationer urskiljas på att nederbörd påverkade andelen misslyckade samtalsuppkopplingar i nätverket. Resultaten kan potentiellt vara av värde för nätverksoperatörer.
