    Abstract: This paper presents an efficient algorithm for determination of optimal path length of terrestrial line of sight microwave communication link. The algorithm computes and adjusts the path length based on the difference between the maximum fade depth the link can accommodate and the actual fade depth that is expected in the link. The algorithm uses N... Show More

    Abstract: In this paper, an approach for optimizing Hata pathloss model based on terrain roughness parameter is presented. The study is based on field measurement of received signal strength and elevation profile obtained in a suburban area for a GSM network in the 800 MHz frequency band. Mostly, standard deviation of elevation is used to characterize terrai... Show More
