CC3351: CC3351 02.11 ax TB measure with WiFi analyzer(EVM)

Part Number: CC3351

Tool/software:

Hi Ti Experts.

Because our company is developing the cc3351 module, we purchased a WiFi EVM device that supports WiFi 6.

When we asked EVM Instrument Company to measure the CC3351 dk board, we currently encountered the TB mode in 802.11 AX, and EVM was currently unable to demodulate the data.

The EVM manufacturer is asking whether all RU allocations have been turned on in the following settings of smart rf studio?

  • Hi Weli,

    Yes all of these should be enabled in our Radio Tool Gui - I recommend downloading our latest version which came out last week: www.ti.com/.../SIMPLELINK-WIFI-TOOLBOX

  • Hi Ti exerts.

    We have downloaded the latest version,
    Then we are trying to use .11ax tb mode.

    We still can't decode .11ax tb mode data properly.

    Have you ever used a WiFi analyzer to demodulate the data of 11ax tb mode?
    If so, can you tell me which brand and model of WiFi analyzer you use?

  • Hi Weli,

    Yes, I have tested 11ax TB using our newest Radio Tool. I use a Litepoint test to test the Wifi signaling.

    In my tester I have to match the GI/LTF settings to what I set in Radio Tool, here is a screenshot of the settings:

    Everything I highlight in Yellow are the settings I have to ensure match up to the Radio Tool settings. Do you have these types of settings in your tool? How do you typically test 11ax TB?

  • Dear Ti Experts.

    Thanks for your support.

    I have feedback on your parameter setting to the WiFi Analyzer manufacturer.

    They will confirm their instrument parameters,
    I'll close this question first. If you need any help, I'll ask another question.
