Abstract

The mobile network planner relies on a signal propagation path loss model to enhance the wireless communication system in order to avail an acceptable limit of quality of service for the mobile users. Hence, it is very crucial to find a robust propagation model suitable for a range of environmental conditions which may be implemented as guidelines for planning of cell in wireless communication systems. Path loss is the regulating factor in limiting the performance of the system in urban areas. It is essential to develop an appropriate path loss model which predicts the path loss values depending on the received signal strength. In the present paper, the COST 231 propagation model has been optimized by making use of Newton’s method. The statistical measures like absolute average error and root-mean-square error were calculated for the frequencies 800 and 1800 MHz. From the simulation results, it is found that the optimized model best acclimatizes with a smaller mean relative error. The lesser value of mean error supports successful implementation of the optimization technique and therefore suggested that the present optimized model can be useful for telecommunication providers to improve the service for mobile user satisfaction.
