Emissions mask, channel width & numbering discussion
Brief discussion of Jan Kruy's input to TGy reflector
Discussion of bare bones i & j emissions mask for the 11y specific channel widths
Suggestion of having Filters only at channel edges
Discussion of section 68-69 in FCC 05-56, section 90.1323 page 45
Channel edge specification similar to UNII band 2 (at band edge ERP should not
be greater than FCC specified limits)
Channel numbering and widths: Page 1138 of Annex J of Draft 6.0 of Rev-ma is one example of a channel numbering scheme and their center frequencies. Specifically clauses 17.3.2.3, & 17.3.8.2
Channel numbering from 130 to 140 and their frequencies discussed. Channels numbering specifications differ slightly for each channel width specification (Note: See 802.11-06/0855r1 for Annex J summary info)
In Annex J of draft 6 in Rev-ma, page 1136 Table J.1 Regulatory Class 4 in is US 5.47 to 5.725. Its channel 100 is 5.5GHz center frequency. Also see table J.1, page 1138 3rd column
Regulatory Class 5 uses ISM channel rules (see Annex J summary 06/0855r0)
Discussion of beacon query "country information element" from Rev-ma draft 6
Country info element beacon frame can differentiate country channel class Pg 112 & 113 section 7.3.2.9 (3 octets of regulatory triplet, regulatory class, coverage class)
Brief discussion of smaller or dynamic channel width specifications. Suggestion that concept of a channel is changing. Reference to building a new PHY not realistic. Chair suggests informative annex for discussion of this concept and other info.
Discussion of next teleconf duration – add 30 minutes so more discussion can take place
Chair moves adjournment of telecom at 1503 ET
