    Performance Evaluation and Optimisation of JAWWAL 3G Mobile Network
    (Engineering for Palestine Conference, Palestine Polytechnic University, 2025-09-29) Tarteel Khaled Sider; Safa Nassereldin; Ali Jamoos
    In this paper, a comprehensive research study is carried out on the performance evaluation and optimization of the JAWWAL 3G mobile network in Palestine. Particularly, we present a case study on the planning, evaluation, optimization, and implementation of a 3G mobile network in Idna village, Hebron city, Palestine. The 3G mobile network performance is evaluated by using the so-called drive test through the key performance indicators (KPIs). After a driving test was conducted in the region, the initial network analysis and evaluation showed that the network coverage ratio is 21.5%, the network service quality ratio is 11.1%, the downlink throughput ratio is 6.1%, and the uplink throughput ratio is 35%. Based on these ratios, which are considered to be poorly evaluated, the area lacks coverage and quality of the network service. To overcome these drawbacks, we propose to plan and implement a new cell site in this area. Accordingly, after the planning and construction of the new cell site, the network has been analyzed and evaluated through a driving test. The results show considerable improvement in all KPIs. Indeed, the network coverage ratio is increased to 58.7%, the network service quality ratio is increased to 61.1%, the downlink throughput ratio is increased to 69.5%, and the uplink throughput ratio is increased to 74.5%.

    Propagation Model Tuning for Terrestrial Microwave Links in Palestine
    (IEEE, 2022-07-26) Ali Jamoos
    In this paper, we have studied the terrestrial microwave links operated by the Palestinian mobile network operator (JAWWAL). Particularly, we have analyzed the path loss power measurements from 90 active terrestrial microwave links at three different frequencies which are 15GHz, 18GHz and 23GHz covering all geographical locations in the West Bank. The length of these microwave links varies from about 0.174Km to 33.864Km. The path loss power measurements were compared with that of the theoretical free-space propagation model as well as with the results obtained from Mentum Ellipse software simulation tool. The root mean square error results show that the free-space model is far away (7.64 dB) from the measured data. Therefore, we have suggested to tune the free-space propagation model based on linear least squares method. The proposed tuned free-space model yields better fit to the measured data with reduced root mean square error of 5.84 dB. In addition, the suggested tuned model yields comparable results to that obtain by Mentum Ellipse simulation.
