ABSTRACT

This research work presents gsm pathloss through Kwara State Polytechnic permanent site, Ilorin. The study area is between latitudes 080 321 37.611 and 080 341 27.911, longitudes 040 381 07.711and 040 381 17.311. The elevations of the two reference points were 350 and 364 meters respectively. The signal strength of MTN, GLO, AIRTEL and ETISALAT networks were measured with TECNO D3 Android mobile receiver from Base Transceiver Station (BTS) at intervals of 100 meters. The linear distance covered from the array of cell site was 3,100 meters. The signal strength data obtained were used with appropriate equation to determine the pathloss in the study area. The path losses obtained were compared with the path loss computed from COST-231 HATA and LEAST SQUARE MODELS for the suburban area where the measurements were taken. The results proved that the predicted and the measured path loss were intertwine and close to each other and the values obtained shows that the people living in the study area are suffering from the poor gsm communication system. This paper is recommended for radio engineers and gsm telecommunication companies for effective planning.
