    CTS 341: Meter Command – Dynamic and Adaptive Network Management (Sponsored)

    https://youtu.be/8u0hXi-tMIk Meter is going one step beyond AI chat bots with their product Command. It’s a generative UI that goes beyond command line interface and adds visuals to create custom dashboards using a natural language interaction. A network operator can make queries for their network, configure SSIDs, new networks, and other network changes by using plain English. Meter Command allows a network operator to be highly efficient and productive. A simple English query can yield results of the network. Or if you need to build a custom dashboard for a CTO, you can ask Meter Command to build that for you. No extra coding experience required. Another great aspect of Meter Command is it is built to be collaborative with other team members. Troubleshooting can be kept in a single canvas and updated dynamically. Dashboards can be created and modified on the fly by collaborating with other team members. Check out the episode and the screenshots below. Resources * https://meter.com/command

    CTS 340: Wi-Fi 7, MLO, and Preamble Puncturing (Sponsored)

    Wi-Fi 7 is just around the corner. It offers new features and complexities to help increase throughput and maintain low latency. In this episode, we’re joined by Arista Networks who gives us a run down on the different versions of MLO. With their testing, they’ve seen a few versions of MLO being used. As well as seeing when MLO gets triggered and how much throughput you can acquire when connecting to the same AP on different bands. For stability, Arista Networks displays how preamble puncturing works when interference is detected in a wide channel. The specific channel seeing the interference is removed from the channel width without affecting the other channels. Check out the video to see it in action.
