Dear all,

I have read through the paragraphs regarding PLC, and following are my comments:

1. IEEE 1901.1(PLC-IOT) is missing in the reference, and the recommended reference format can be as below:
[IEEE1901.1] "IEEE Standard for Medium Frequency (less than 12 MHz) Power Line Communications for Smart Grid Applications", 2018, https://standards.ieee.org/standard/1901_1-2018.html.

2. In section 6.6, there is one typo in the paragraph as below. This paragraph is introducing 1901.1, thus the " variant (IEEE1901.2)" should be " variant (IEEE1901.1)"
//////Example: Use of PLC (IEEE1901.1) for WASA in Smart Grid
   ///Many sub-systems of Smart Grid require low data rate and narrowband
   ///variant (IEEE1901.2) of PLC fulfils such requirements.  Recently,
   ////more complex scenarios are emerging that require higher data rates.

3. There is a small error in the table in section 3.6. The frequency range for IEEE1901.1 is smaller than 12MHz, not 15MHz

4. In section 3.6 PLC, there are 2 paragraphs introducing IEEE1901 and IEEE1901.2, but the introduction for IEEE1901.1 is missing. Here I write an example:
[IEEE1901.1] defines a medium frequency band (less than 12 MHz) broadband PLC technology for smart grid applications (SGPLC) based on orthogonal frequency division multiplexing (OFDM). By achieving an extended communication range with medium speeds, this standard can be applied both in indoor and outdoor scenarios, such as Advanced Metering Infrastructure (AMI), street lighting, electric vehicle charging, smart city etc.

B.R.

主题: [6lo] 2nd WGLC for draft-ietf-6lo-use-cases

This initiates a 2nd WGLC on the use-cases and applicability draft:

https://datatracker.ietf.org/doc/draft-ietf-6lo-use-cases/

The first WGLC initiated in November 2018 didn't conclude due to lack of responses. However the workgroup has reviewed the latest revisions and authors have addressed the comments in -09 pending one comment https://mailarchive.ietf.org/arch/msg/6lo/Ib4P3Zq-CCf6Ye4uKLU-NIHlp_I/#<https://mailarchive.ietf.org/arch/msg/6lo/Ib4P3Zq-CCf6Ye4uKLU-NIHlp_I/>

As per the discussion at the 6lo session during IETF 108, this starts a WGLC. This WGLC will conclude in two weeks on Monday October 19th.

Please send your comments to evaluate progressing this draft.

Thanks,
Shwetha
