Abstract: In this paper, development of path profile for 6GHz C-band terrestrial line-of-site microwave link is presented. The path (elevation) profile data set is obtained using Geocontext online elevation software. With the path profile, the minimum antenna elevation and the minimum antenna mast heights for effective line of site installation are determined. According to the results, when path inclination is greater than zero, antenna elevation is 105.873m and 88.528m at the transmitter and receiver respectively, with antenna mast height of 36.712m at both the transmitter and the receiver and critical clearance of 4.787m at a distance of 1897.626m from the transmitter. However, when path inclination is equal to zero, antenna elevation is 88.528m at both the transmitter and receiver with antenna mast height of 19.367m and 36.712m at the transmitter and receiver respectively. In this case, the critical clearance is 0 m (zero meter) at a distance of 686.641m from the transmitter.

Abstract: This paper investigated the factors affecting students brand choice for mobile phones among university students at the University for Development Studies, Navrongo Campus in the Upper East region of Ghana. The research was a cross-sectional design with 300 students. The students were chosen using stratified random sampling. Statistical Package for Social Sciences version 20 was used to analyze the data. The results show that three major factors directly influencing students choice of brand of mobile phones in this study were user-friendliness, quality and price. Among all the mobile phone brands, the most used brands by the students were Nokia and Samsung. Nokia and Samsung together constituted 56 percent of phones used by the respondents. However, for future use, 45 percent are planning to use Nokia while 61 percent for Samsung. The price of mobile phones ranged between GH₵ 50.00 and GH₵ 301.00. Fashion and durability were factors that correlated and have relationships with the decision to buy a brand of mobile phone. This is one of the few studies in consumer behavior to assess preferences in a consumption context of mobile phone industry. The findings are useful for mobile phone dealers and manufacturers to incorporate these preferences by diversifying the types of mobile phones with different ranges of corresponding prices to meet consumers’ needs and income levels.
