Abstrak – Spatial reuse (SR) merupakan salah satu fitur pada standar IEEE 802.11ax WiFi 6. Secara umum, SR digunakan untuk meningkatkan jumlah transmisi paralel yang dapat dilakukan antara node (AP maupun STA) dalam jaringan yang overlap (OBSS) satu sama lain dengan cara melakukan adjustment terhadap Clear Channel Assignment (CCA) threshold-nya. Peningkatan jumlah transmisi paralel ini pada akhirnya akan memaksimalkan penggunaan channel untuk transmisi data, sehingga dapat meningkatkan throughput. Penelitian ini bertujuan untuk melakukan studi mengenai operasi SR dan pengaruhnya pada throughput. Simulasi dilakukan menggunakan simulator ns-3 dengan topologi jaringan yang terdiri dari dua Basic Service Set (BSS) yang overlap. Hasil simulasi menunjukkan bahwa penggunaan SR meningkatkan nilai throughput hingga 13 Mbps pada topologi jaringan yang digunakan dibandingkan jika SR tidak digunakan atau diaktifkan. Abstract – Spatial reuse (SR) is one of the features of the IEEE 802.11ax WiFi 6 standard. SR is used to increase the number of parallel transmissions between nodes (AP and STA) in networks that overlap (OBSS) with each other by adjusting the Clear Channel Assignment (CCA) threshold value. Increasing the number of parallel transmissions will maximize the channel utilization for data transmission, thereby increasing network throughput. This research aims to study SR operations and their effect on throughput. The simulation was carried out using the ns-3 simulator with a network topology consisting of two overlapping Basic Service Sets (BSS). Simulation results show that using SR increases the network throughput value by up to 13 Mbps in the simulated network topology compared to if SR is not used or activated.
