Abstract

Information carried through the wireless medium are subject to impairments due to several events along the route of transmission, leading to path losses. For effective network planning therefore, these events and their effects on radio propagation need to be known and accounted for.  In this work, we studied the radio propagation profile, along selected routes in Ilorin, Kwara State due to transmissions from the NTA, Ilorin, the Harmony FM and the University of Ilorin FM transmitters. Each of the routes are divided into segments, as seen, in the figures. The measurements were made, using the N9432C Agilent spectrum analyzer. Analysis, of obtained data, showed that the nature of the environment, affects radio propagation. Even within the same route and all other conditions the same, the models’ relative performances vary, from one segment to the other. The performances of the models corroborate the notion that empirical models are environment-specific.
