Abstract

ABSTRACT

This research investigated the effects of foliage on mobile networks. The wet season is known to be characterized by increase in foliage due to increased moisture content. Global System for Mobile Communications (GSM) signal strength measurements of two networks were taken during the dry season and repeated during the wet season at the same point. These data were then analyzed using the systematic approach of collecting and collating relevant data to determine the relationship between the signal strength loss, foliage depth and frequency. To ensure greater accuracy of results, two networks (Airtel and MTN) were considered. Furthermore, signal strength measurements were conducted in Maiduguri city and Auno rural area around Maiduguri. GSM signals were discovered to suffer greater losses during the rainy season due to increased foliage. Losses of between -4dBm and -10dBm were observed in rural and suburban areas while the losses observed in the metropolis were between -0dB and -4dBm These losses, though not significant in urban areas, were significant in the rural and suburban areas. The result obtained for the developed Maiduguri model is observed to be within the range when compared with Wiessberger and ITU models.
