A Comparative Analysis of Cell Planning for Path Loss Reduction

Nagendra Sah
Abstract—In this paper, an optimized cell planning for path loss reduction has been proposed. A 10 by 10 Km square block is considered as Traffic Required Area (TRA) which consists of number of base stations (BSs) and mobile stations (MSs). The optimization algorithm: Tabu search, is used to optimize the position of base stations in such a way that the path loss (or reciprocal signal strength) between the BS and MS is minimum (or maximum). In order to accommodate large number of users, algorithm adds new BSs and also drops existing BSs. Then, the propagation path loss from a base station to a receiver point was calculated according to Okumura-Hata and Walfisch-Ikegami model. These are empirical models based on the measurement data. In order to improve the efficiency of the Tabu search, intensification through dynamic Tabu list and Tabu time have been used. Results obtained showed that proposed algorithm is highly effective. There is a capacity improvement by 14% at 900 MHz and 15% at 1800 MHz and the corresponding reduction in outdoor propagation path loss varies from 1 to 15 dB.
