Institutional Repository UIN Sunan Kalijaga YogyakartaANALISIS PERFORMA DAN OPTIMALISASI ACCESS POINT DI FAKULTAS SAINS DAN TEKNOLOGINIM.: 22106050065Muh Alwizariel Fauzil Syamil FaradhisauthorThe availability of a stable wireless network Wi-Fi in a high-density environment, such as the Faculty of Science and Technology at UIN Sunan Kalijaga, plays an important role in supporting academic activities. Although 40 Access Point (AP) units have been installed, the existing network infrastructure still experiences several problems, such as uneven signal distribution, blank spot areas, and unstable connections during peak usage hours. This project aims to analyze the performance of the existing Wi-Fi network based on the Received Signal Strength Indicator (RSSI), Signal-to-Noise Ratio (SNR), and channel interference parameters, as well as to design an optimization scenario for AP configuration and placement without adding new hardware devices. This project uses the Continuous Passive Site Survey method with the help of Ekahau AI Pro software. Data collection was carried out in four different time periods to compare network performance under low traffic conditions during Ramadan and high traffic conditions after Eid al-Fitr. The optimization process adopts the PPDIOO (Prepare, Plan, Design, Implement, Operate, Optimize) framework by adjusting AP placement, channel planning, and transmit power configuration. The evaluation results show that the existing network experiences severe saturation and Co-Channel Interference (CCI) in the 2.4 GHz frequency band. In addition, the 5 GHz frequency band experiences coverage reduction due to signal attenuation caused by reinforced concrete walls. Through redesign simulation, this project proposes an optimization solution to ensure the network coverage meets the Quality of Service (QoS) standards, namely RSSI ≥ -65 dBm and SNR ≥ 25 dB. The final results of this project provide several technical recommendations, including AP relocation, frequency management, band steering activation, and transmit power adjustment to improve network stability and user access quality.005.12 Software System Analysis and Design/Sistem Analisa dan Desain Perangkat Lunak2026-06-02UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SAINS DAN TEKNOLOGIThesis
