Abstract
Fading is a concept that is associated with communications, be it digital or analogue. This work deals with the careful analysis, performance, and evaluation of fade margin on a particular mobile network in Nigeria, using Auchi as a case study. With the careful analysis that was carried out on three (3) different links using some collated data such as latitude, height of tower, power, antenna gain and model, frequency, path length and distance etc. It was discovered that the said mobile network fade margin across the three different links was within the acceptable range of 10db to 30db. Also, it was discovered that the longer the pathlength, the higher the fade margin value, as confirmed in the results. Thus, the major characteristics needed to determine the fade margin and evaluation process were effective and realizable.
