A SYSTEMATIC EVALUATION OF LINK BUDGET FOR EFFECTIVE 900MHz GSM COMMUNICATION SERVICES
Abstract
This paper describes the various basic parameters necessary to determine a high level link budget for radio communication operating at 900MHz spectrum band. It considers a typical Lagos terrain by using the Okumura and Hata prediction model in calculating the path loss between a transmitter and mobile receivers. In this paper, the rain attenuation calculation from the updated ITU model was incorporated into the link budget to improve GSM communication during rainfall. These parameters can be used to predict a reliable communication ranges for the design and implementation of future GSM communication systems.
Keywords: 900MHz Spectrum Band, Prediction model, Link-budget, Path loss, Rain attenuation, Communication ranges, GSM Communication.
