Hi Bo,
Could you please add the following new PHY SP into 27 Jan teleconference:
Do you agree to add the following text to TG bp SFD?
- 11bp recommend following WPT channels for WPT transmission in US
- Three channels with BW 500kHz and center frequency being 902.5MHz, 909.5MHz, 915.5MHz
- Three channels with BW 1MHz and center frequency being 902.5MHz, 909.5MHz, 915.5MHz
- Three channels with BW 500kHz and center frequency being 902.5MHz, 909.5MHz, 915.5MHz
[Ref: 11-26/0131r0]
Some highlights of this updated SP:
- Existing motion (page 69 in 11-25/1692r17) already support that “existing and future agreed sub-1GHz channelization schemes can be applied to WPT”
- The above proposed WPT channel recommendation aims to obtain specific benefit for specific regulation body (avoid FH in US).
- The above updated scheme define three channels per BW with pretty wide separation, which may effectively mitigate frequency selective fading problem.
- The above three 1MHz channel are also with alignment to 802.11ah channels.
- We think communication is in higher priority than WPT in sub-1GHz. Defining too many WPT channels may bring interference to communication.
Best regards,
Panpan
