This paper determines the path loss exponent of the GSM 900 MHz and 1800 MHz bands in Ilorin, Kwara state of Nigeria. A comprehensive signal strength measurement campaign, using an Agilent spectrum analyzer, was carried out in 12 different routes representing, virtually, the entire metropolis of Ilorin. In computing the path loss exponent, a different approach from the more frequently used linear regression approach, was used. The experimental data reveal a lot of findings, chief amongst which is the strong influence of the terrain profile on the path loss of the environment. Consequently, the path loss exponent obtained, especially for the GSM 900, is lower than the expected value as reported in the literatures.enPath loss exponent,Free Space Path Loss,Article
