A Wi-Fi assessment project that also required measuring network performance, including jitter (variation in latency) and packet loss. iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. h for AP information to be connected. iperf -c 192. One way to use the iPerf tool is testing between an iPerf Server and an iPerf Client on the same wired segment. When using Iperf to test the speed, we need to set one PC as a server and another PC as a client, in this FAQ we set PC A as server and PC B as a client. 11ac Wave 2 Wi-Fi products with advanced management capabilities deliver high capacity and fast installation in an affordable package – to connect people, places and things. The downstream test is vice-versa, meaning that the iPerf server is set on the wireless client itself and the iPerf client is on the wired side pushing the traffic to the wireless client, in this scenario this is considered downstream. 11b, for which we collect our results. Measurement Tools - Iperf. 11 traffic and interference, nd the APs using each channel. Using a completely different set of computers I was getting very similar results with them connected via a Gigabit link. WIFI Modules Test with ODROID Series We used the iperf utility to measure wireless network performance. Measuring TCP, UDP and SCTP bandwidth performance.
