Title: Sensitivity of Received Power in Antenna Down-Tilt in Cluttered Mobile Environments a case study Of West Africa Telecom Industry
Authors: Dotche, Koffi Agbeblewu
Issue Date: 11-Aug-2010
Abstract: In Code Division Multiple Access (CDMA) mobile environment, transmitter and receiver signals are heavily influenced by the effect of clutter surrounding both the transmitter and the receiver. Therefore the ability to optimize a CDMA system is dependent on the initial system configuration at the deployment stage. This includes the site location, antenna type, orientation, down-tilt and the choice of propagation model which contributes greedily to a better optimization of the network. It is a very important function in cellular radio system design. For the prior optimization of the network, the propagation parameters should be optimized. The parameters that influence the received signal such the terrain topology with regard to the mechanical down-tilt are presented. In incorrect coordinate of the BTS cell site, a poor coverage was also observed. Furthermore, the measurement of the received power from CDMA pilot carried out during the drive-test in Greater Accra was used to evaluate the excess path loss. This excess path loss in value was obtained from the comparison between Hata-Okumura Models and the measured path loss. The prediction response was not satisfactory in the study area therefore the prediction model was then tuned by the use of the least square algorithm.
