Abstract

With the increase in multimedia content and gaming, the bandwidth used by a household has increased considerably. With HD video and gaming using up to 25Mbps per host , and with services like cloud gaming demanding of high network performance with a tolerance of delay ranging from 300ms to 25ms, the improvement on the network devices and network protocols and firmware are always under the development. Because of these requirements, there is a need for high bandwidth, high performance wireless router systems for the home network to handle more and more traffics in many cases. Wi-Fi 6, also known as 802.11ax, is the newest implemented IEEE 802.11 standard wireless network protocol that has been used in devices in the market. Its maximum link speed is 9608Mbps or 9.6Gbps. Wi-Fi 6 is much faster than Wi-Fi 5, however speed wasn’t necessary it’s main goal. Wi-Fi 6 was created to make a wifi network perform better when a lot of devices are connected. Wi-Fi 6 has MU-MIMO (Multi-User, Multiple-Input Multiple-Output) technology and higher bandwidth channels, therefore shows much better performance. Our goal for this project is to see how is Wi-Fi 6 implemented in ns-3 and also test some scenarios to see its performance. In our test scenarios, we will use ns-3 simulate a geographic region covered by Wi-Fi 6 with several game users and other stream users who share the same network to see how throughput and latency is affected.
