Monitor Wi-Fi 6E and 6 Readiness

About Wi-Fi 6E and 6 Readiness and Its Benefits

You use the Wi-Fi 6E and 6 Readiness feature to determine the following:

  • The percentage of clients that are Wi-Fi 6E and 6 capable.

  • The percentage of AP infrastructure that is Wi-Fi 6E and 6 ready.

  • Based on the preceding information, recommendations are provided about the actions that you can take to experience the full benefits of the Wi-Fi 6E and 6 network.

To provide these recommendations, Cisco DNA Center does the following:

  • Assesses the Wi-Fi capabilities of wireless clients.

  • Collects AP inventory to determine which of the APs are managed by Cisco DNA Center, and then assesses the Wi-Fi capabilities of those APs.

  • Determines the types of wireless controllers that are in the network and whether the software that is installed on the wireless controllers is Wi-Fi 6E and 6 ready.

  • Determines the wireless LAN configuration and whether are not Wi-Fi 6E and 6 features are enabled.


Note

Under certain conditions, Wi-Fi 6E wireless client latency or airtime efficiency data might be less optimal than Wi-Fi 6 or legacy Wi-Fi, regardless of the capability of the AP platforms. For example, Wi-Fi 6E might be less optimal when:

  • Significantly more clients are connected to Wi-Fi 6E APs than to non-Wi-Fi 6E APs.

  • There is more interference from poor RF design in the Wi-Fi 6E environment than in the non-Wi-Fi 6E environment.

  • Clients connected to Wi-Fi 6E are positioned to have poor signal strength (RSSI).

The preceding scenarios also apply to Wi-Fi 6 versus legacy Wi-Fi.

Step 7

Use the Wireless Airtime Efficiency dashlet to compare the Average Airtime Efficiency between Wi-Fi 6E, Wi-Fi 6 traffic and non-Wi-Fi 6 traffic for each of the access categories (voice, video, best effort, and background).

Wireless Airtime Efficiency Dashlet

You can view the wireless airtime efficiency for the following access categories: Voice, Video, Best Effort, Background, and All. Default is Voice.

This dashlet includes the following tabs:

  • Latest: Displayed by default. The bar graph allows you to compare the average airtime efficiency (in units of Bytes per mill-seconds) between Wi-Fi 6E, Wi-Fi 6 traffic and non-Wi-Fi 6 traffic for the chosen access category.

    The spectrum is efficiently used if the APs radios can send more traffic (successful Bytes transmitted to the client) in less airtime (microseconds) than other networks under similar RF conditions. An efficient network might allow more video or voice calls.

    Traffic is classified as the following:

    • Wi-Fi 6E traffic is the traffic sent from Wi-Fi 6E APs to clients that are associated as Wi-Fi 6E.

    • Wi-Fi 6 traffic is the traffic sent from Wi-Fi 6 APs to clients that are associated as Wi-Fi 6.

    • Non-Wi-Fi 6 Traffic is the aggregate of the following:

      • Wi-Fi 6 APs to non-Wi-Fi 6 capable clients.

      • Non-Wi-Fi 6 APs to non-Wi-Fi 6 capable clients.

      • Non-Wi-Fi 6 APs to Wi-Fi 6 capable clients.

    Note

     

    A Wi-Fi 6 capable client operates in non-Wi-Fi 6 mode when it connects to a non-Wi-Fi 6 AP.

  • Trend: Click the Trend tab to display a trend chart. This color-coded trend chart shows the number of clients that are associated to the different wireless network modes (Wi-Fi 6E, Wi-Fi 6 or non-Wi-Fi 6) over a time range.
