Dear 802.11 participants,

There is a new revision of two documents related to of the liaison response to ETSI TC BRAN's liaison on Solid-State Weather radar operations in 5 GHz that affect DFS operation (TR 104 893):

Technical considerations document (link): I have added a new part (#2) to the technical response section of the document. This new part addresses comments for TR 104 893 in a more direct and structured fashion. Part 1 still exists in the document for some general comments, but I intend to remove it as part #2 is better structured wrt comments.
Liaison response letter (link)

Please do review both the documents and send me your comments at your earliest as we may consider a motion to approve them in IEEE 802.18 RR-TAG during the plenary next week.

For those who are traveling to Montreal, have a safe flight!

Regards,

Gaurav

Hi Gaurav,

Thank you for referring to Japan MIC’s material in your slides!

But it would be better to refer to p.8 of the following MIC material which reflects the final approval.

# In the final version, we’ve changed two conditions for the minimum number of pulses per cycle under the pulse patterns and the last item under the detection conditions…

Best regards,

tomo

Hi Marc,

I would like agenda time to present the technical considerations for operation of solid-state weather radars in DFS channels. This has been a topic under discussion within the IEEE 802.18 RR-TAG and I would like to present to 802.11 COEX SC for more feedback on the same. If you could add me to the agenda for the (newly added) Tue AM1 slot, that would be great! DCN: 18/26-0055 (https://mentor.ieee.org/802.18/dcn/26/18-26-0055-04-0000-considerations-for-solid-state-weather-radar-operation-in-dfs-channels.pptx)

Regards,

Gaurav

Coex SC will meet during the July 802.11 meeting.

Please let me and CoexSC know by replying to this mail if you would like to contribute with a submission to the meeting.

For planned submissions, please provide the Title / DCN number and a rough estimate how much time I should allocate for your presentation.

Coex SC is scheduled to meet during the Wednesday PM2 slot (16.00h local time of the meeting venue).

All the best,

Marc
