Re: [STDS-802-11-TGBP] Latest revision PDT AMP PHY Introduction.



Thank you Nelson,

 

I think the current version lakes fundamental non-normative aspects of the PHY clause.

I suggest the following changes:

40.1 Introduction to the AMP PHY

This clause specifies the PHY entity for an Ambient Powered (AMP) system operating in the 2.4 GHz and sub-1 GHz bands.  An AMP non-AP STA can operate using energy harvested from wireless signals of the AMP DL PPDU and/or using Wireless Power Transfer (WPT) waveforms described in this clause.

Using this defined PHY entity at the non-AP STA is allowing it to work without filtering, mixing, accurate clock or amplification, getting orders of magnitude improvements in power consumption and complexity 

 

For each operating band, the AMP PHY is described separately in the downlink and uplink directions.  Here, the downlink direction generally refers to messages transmitted from an AMP AP to a non-AP AMP STA or an AMP-enabled non-AP STA using AMP downlink (DL) PPDUs.  The uplink direction generally refers to communications in the opposite direction using AMP uplink (UL) PPDUs.
