Abstract

The research study was carried out by measuring Received Signal Power along the propagation path of an Outdoor Environment of two GSM Network Service Providers in Abavo, Ika, South Local Government Area of Delta State, using a Network Monitor. The difference in signal levels in relation to distances of the Network Service Providers Base Stations (BS) to the Mobile Station (MS) were closely studied. The effects of the main characteristics of radio wave signal  in relation to that of natural environment were examined. For these effects to be studied, Measurements of Received Signal Power were taken in Open and Built Up Environment by moving away from the Network Service Provider Base Station. Using the standard parameter and the computed values of the Free-space and HataModels obtained; values of the Received Signal Power and Path-losses were found to fall short significantly from average values obtained from Measurement. For the Open Environment, the mean variation was around 57.72 dBm and 47.21dBmfor Received Signal Power and Path-losses respectively. The corresponding values of the Received Signal Power was 9.8 dBm for the Built-up Environment: hence, the Received Signal Strength of all the Network Service Providers were generally below standard for optimum service delivery in all the areas investigated.
