Re: [STDS-802-11-TGBE] PDT-PHY- Transmit specification: Clock frequency and modulation accuracy

Hi, Wookbook and MJ.

Thanks for the nice work.  Please see my comments attached. For 1253.

 

Regards,

Youhan

Hi all,

 

I just uploaded draft text proposal for PDT-PHY- Transmit specification: Clock frequency and modulation accuracy.

11-20/1252r0 PDT-PHY-Frequency Tolerance

11-20/1253r0 PDT-PHY-Modulation Accuracy

 

Please let us know if you have any comment.

 

Thanks MJ for your work.

 

Best regards,

Wook Bong Lee

Hello all,

This is for PHY- Transmit specification: Clock frequency and modulation accuracy.

As you can find in 11ax spec, we have following two sections for this.

  • 34.3.19 – Transmit specification
    • 34.3.19.3 Transmit center frequency and symbol clock frequency
    • 34.3.19.4 Modulation accuracy
      • 34.3.19.4.1 Introduction to modulation accuracy tests
      • 34.3.19.4.2 Transmit center frequency leakage
      • 34.3.19.4.3 Transmitter constellation error

 

There is one motion for these sections, i.e.

802.11be supports -38 dB as the Tx EVM requirement for 802.11be 4096 QAM.

[Motion 112, #SP20, [9] and [70]]

 

I have few things to discuss. For those thing, I am thinking we can make it TBD. Will write a contribution to discuss that.

 

Other than that, mostly it will be similar to 11ax.

 

MJ kindly volunteered for writing above sections.

He will share draft when it is ready.

 

If you have any suggestion, please let us know.

Best regards,

Wook Bong Lee
