Jaringan Wi-Fi berperan penting dalam mendukung aktivitas akademik kampus, namun implementasinya di Gedung A FPTI UPI, khususnya Lantai 4 dan Lantai 5, masih menunjukkan kualitas layanan tidak konsisten akibat penempatan access point yang tidak didasarkan pada analisis spasial, sehingga menimbulkan blind spot dan penurunan performa jaringan pada jam sibuk. Penelitian ini bertujuan memetakan distribusi spasial kualitas sinyal Wi-Fi, mengukur kualitas layanan (QOS) pada kondisi sepi dan ramai, menganalisis kesesuaian antara kualitas sinyal dengan QOS, serta menyusun rekomendasi penempatan ulang access point. Penelitian menggunakan pendekatan kuantitatif melalui site survey dengan NetSpot Pro untuk mengukur signal strength, SNR, dan SIR pada 21 titik di Lantai 4 dan 20 titik di Lantai 5, pengukuran QOS menggunakan Wireshark berdasarkan standar TIPHON, serta simulasi optimasi access point menggunakan Ekahau AI Pro. Hasil penelitian menunjukkan titik dekat access point konsisten memiliki RSSI dan SNR terbaik, sedangkan titik jauh yang terhalang partisi berpotensi menjadi blind spot, dengan SIR di Lantai 5 berada pada kategori kritis, yaitu rata-rata 3,1 dB pagi hari menurun menjadi 2,2 dB siang hari. Throughput menurun signifikan pada kondisi ramai, sekitar 69,0% di Lantai 4 dan 69,6% di Lantai 5, meskipun packet loss tetap sangat baik. Simulasi penambahan access point dari tiga menjadi 11 unit di Lantai 4 dan 10 unit di Lantai 5 mampu memperbaiki cakupan sinyal, dengan lebih dari 86% area kedua lantai mencapai signal strength dan SNR optimal. Penelitian menyimpulkan bahwa integrasi analisis spasial dengan pengukuran QOS memberikan dasar komprehensif dan terukur bagi optimasi jaringan Wi-Fi kampus. Kata kunci: Jaringan Wi-Fi Kampus, Site Survey, Quality of Service, Analisis Spasial, Access point Campus Wi-Fi networks play an important role in supporting academic activities; however, their implementation in Building A of FPTI UPI, specifically on the 4th and 5th floors, still shows inconsistent service quality due to access point placement that is not based on spatial analysis, resulting in blind spots and network performance degradation during peak hours. This study aims to map the spatial distribution of Wi-Fi signal quality, measure Quality of Service (QOS) under quiet and crowded conditions, analyze the correspondence between signal quality and QOS, and develop recommendations for access point repositioning. The study employs a quantitative approach through site surveys using NetSpot Pro to measure signal strength, SNR, and SIR at 21 points on the 4th floor and 20 points on the 5th floor, QOS measurements using Wireshark based on TIPHON standards, and access point optimization simulations using Ekahau AI Pro. The results show that points near access points consistently had the best RSSI and SNR, while distant points obstructed by partitions were prone to becoming blind spots, with SIR on the 5th floor falling into the critical category, averaging 3.1 dB in the morning and dropping to 2.2 dB in the afternoon. Throughput decreased significantly under crowded conditions, by around 69.0% on the 4th floor and 69.6% on the 5th floor, although packet loss remained very good. Simulated access point addition, from three to 11 units on the 4th floor and 10 units on the 5th floor, was able to improve signal coverage, with more than 86% of the area on both floors achieving optimal signal strength and SNR. The study concludes that integrating spatial analysis with QOS measurement provides a comprehensive and measurable foundation for optimizing campus Wi-Fi networks.
