Measurement and analysis of 3G WCDMA network performance case study: Yogyakarta Indonesia

Yogyakarta is an education and tourism city. The quality of internet services is needed to support the education quality and tourist services. These services are supported by 3G WCDMA technology. This paper will discuss the need of Information Technology (IT) for education and tourism sector, and also assesment of the IT performance in Yogyakarta, specially data sevices for mobile devices. The most of user using 3G WCDMA technology, so we focus measure and evaluate the performance of 3G WCDMA services. In Yogyakarta, education and tourism sector spread to many places like urban, sub urban, and rural area. So In this research we investigate the performance at that areas. Some parameters were measured and analyzed is RSCP (Received Signal Code Power), Ec/No (Energy perchip to Noise ratio), CCSR (Call Completion Success Rate), CSSR (Call Setup Success Rate), and SHOSR (Soft Handover Success Rate). This research find that the lowest of CSSR and CCSR percentage is in urban areas, about 90.41% and 91.78%. Some call requests in this area that can be served, but its still upper than CSSR standards (CSSR ≥ 90%). While in Sub-urban, the value of CSSR about 97.33%. SHOSR percentages in all three areas is very good, there aren´t soft handover failure. So by this result, we recommend that services in urban areas should be improved as an impact of large number of user and contour of buildings.
