CTS 194: State of Wi-Fi 6 from WLPC




Clear To Send: Wireless Network Engineering show

Summary: <br> From the WLPC Prague presentation. We’ll go over our presentation and what we’ve found about Wi-Fi 6 from our testing.<br> <br> <br> <br> You can watch our WLPC Prague presentation on YouTube from the WLAN Pros channel. It will include a live Wi-Fi 6 demo where we include the audience.<br> <br> <br> <br> The demo consisted of 10 WLANpi running iPerf3 servers. We asked people in the audience to connect their Wi-Fi 6 devices to an Aerohive AP broadcasting Wi-Fi 6, of course. A Jetson Nano was used to capture frames.<br> <br> <br> <br> The presentation slides can be found <a rel="noreferrer noopener" href="https://www.cleartosend.net/wp-content/uploads/2019/10/Wi-Fi6_in_the_real_world_wlpc_prague_2019.pdf" target="_blank">here</a>.<br> <br> <br> <br> Watch the presentation below:<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> Our process included:<br> <br> <br> <br> * Theory* Lab* Test<br> <br> <br> <br> As of this recording, Wi-Fi 6 still remains in draft. It is not expected to become a standard until late 2020. Today, we are currently over the peak of inflated expectations. <br> <br> <br> <br> At WLPC Prague, we asked the audience three questions:<br> <br> <br> <br> * Do you own a Wi-Fi 6 device?* Have you deployed a Wi-Fi 6 network?* Have you ever connected to a Wi-Fi 6 network that wasn’t yours?<br> <br> <br> <br> Theory<br> <br> <br> <br> To start learning about Wi-Fi 6, we had to start with the theory. That meant getting the source of all information regarding 802.11ax. There were other resources we used as well:<br> <br> <br> <br> * <a rel="noreferrer noopener" href="https://standards.ieee.org/project/802_11ax.html" target="_blank">802.11ax Draft 4</a>* Aruba’s <a rel="noreferrer noopener" href="https://www.arubanetworks.com/products/networking/802-11ax/" target="_blank">802.11ax document</a>* Cisco’s IEEE 802.11ax – The <a rel="noreferrer noopener" href="https://www.cisco.com/c/dam/en/us/products/collateral/wireless/white-paper-c11-740788.pdf" target="_blank">Sixth Generation of Wi-Fi</a>* Aerohive’s <a rel="noreferrer noopener" href="https://content.aerohive.com/802.11ax_dummies_book" target="_blank">802.11ax for Dummies</a>* National Instruments’ <a rel="noreferrer noopener" href="https://www.ni.com/en-us/innovations/white-papers/16/introduction-to-802-11ax-high-efficiency-wireless.html" target="_blank">Introduction to 802.11ax High-Efficiency Wireless</a>* <a rel="noreferrer noopener" href="https://wballiance.com/resource/wi-fi-6-deployment-guidelines-scenarios/" target="_blank">Wireless Broadband Alliance’s Wi-Fi 6 white papers</a>* <a rel="noreferrer noopener" href="https://amzn.to/2WKFA0X" target="_blank">CWNA Study Guide</a> (Chapter 19)* <a rel="noreferrer noopener" href="https://gjermundraaen.com/thewifiairtimecalculator/" target="_blank">Gjermund’s Airtime Calculator</a><br> <br> <br> <br> What about the Wi-Fi Alliance?<br> <br> <br> <br> * Marketing 802.11ax* Wi-Fi 6 certification* What makes a device Wi-Fi 6 certified?* How many are certified today?* Wi-Fi 6* Compatible* Certifiable* Certified<br> <br> <br> <br> Equipment<br> <br> <br> <br> We needed to get our hands on Wi-Fi 6 equipment.
