T The world of information communication technology in Indonesia has now entered a new phase with the presence of 3.5G UMTS-HSPA technology (3rd Generation Universal Mobile Telecommunication System-High Speed ​​Packet Access) or better known as UMTS-HSPA or HSPA. This HSPA technology consists of HSDPA and HSUPA which are the development of 3GPP Rail 6 which is able to provide a significant increase in data rate in the downlink and uplink directions. Theoretically, HSDPA technology is able to provide a maximum data rate in the downlink direction reaching 14.4 Mbps, while HSUPA technology in the uplink direction is theoretically able to provide a data rate of up to 5.8 Mbps. This thesis discusses the performance analysis of the implementation of the HSPA network on the UMTS network in the Balikpapan area. The analysis will focus on Node B HSPA which is the base station on the UMTS-HSPA network. The analysis will begin with the HSPA network configuration, link budget calculations to measure the maximum pathloss in order to get a cell radius based on pathloss. Then the traffic and capacity estimates per service provided by the WCDMA-HSPA network will be estimated based on the number of subscribers and throughput demand of customers. In addition, the performance of the HSPA network will also be analyzed based on the parameters of the drive test results, namely RSCP, Ec/No and OSS statistical analysis, including call setup success rate (CSSR) and call completion success rate (CCSR) which are limited to KPI (Key Performance Indicator). . From the results of the analysis and calculations, the downlink pathloss reaches 146.32 dB with a radius of 1.18 km and the maximum pathloss for the uplink direction reaches 131.4 dB with a radius of 0.543 km. Meanwhile, customer throughput needs reach 168.17 Mbps where one sector is able to provide a throughput of 42.768 Mbps so that 4 sectors per site are needed in the Balikpapan area. Traffic per service during busy hour is 33.33 mErlang for voice, 8.95 mErlang for video and 43.61 mErlang for data. The coverage performance for the RSCP parameter at the SutomoMW site has exceeded the lock value set by the operator, which is 95.25%, while the CSSR and CCSR performance has exceeded the KPI lock value, which the average value is above 99%.
