Capacity Analysis of Wi-Fi 802.11 b, n and ac

This white paper presents a capacity analysis of Wi-Fi standards 802.11 b, n, and ac using the NetSim simulation tool. It outlines various scenarios that simulate and analyze the PHY rate and UDP download throughput as the distance between the access point (AP) and the Wi-Fi device varies. The document details the configuration settings for each standard, including parameters such as operating frequency, channel, and transmitter power. It provides results for different distances and path loss exponents, illustrating the relationship between distance, PHY rate, throughput, and received power. The analysis includes detailed tables and figures that summarize the performance metrics for each standard under varying conditions. Additionally, the paper discusses the radio propagation model used in the simulations, emphasizing the log-distance model for calculating received power. Overall, the document serves as a technical reference for understanding the performance characteristics of these Wi-Fi standards in different operational scenarios.
