Overall Comments on Proposed ProjectThe 4.9 GHz band is allocated for public safety use in theUS. I am concerned that Japanese laptops with 802.11acards may be used in ad hoc mode in the US by visitors andmay interfere with public safety radios.
Use a band that is not allocated for public safety in the US.
The PAR and the 5 criteria are only going to cover standardchanges according to Japanese specific regulations. If inother parts in the world (e.g. in Europe) individual countriesalso come up with different regulatory requirements howdoes the WG plan to deal with those? Would that alwaysrequire a new project request or shouldn’t we try to find ageneral solution for that issue (e.g. a kind of informativeannex).
Clarification required.
if we ammend the IEEE802.11 standard to comprehendinteroperating in the new bands at 4.9 and 5.03 GHz inJapan then we should update the standard to comprehendthe existing unique channels in Japan - channel 14 in the2.4 band and channels 34,38, 42 and 46 in the 5.15-5.25band. It is implied that the requirements for Ch 14 are thesame as those for Chs 1-13; that is not the case. Similarlythe power and channelization for the 5.15-5.25 band inJapan is not the same as that for the US. In fact, the existing spec only reflects requirements for the US in the 5 GHzband.
update the existing standard to include normative andinformative text that reflects the existing rules in Japan foroperating WLANs in the 2.4 GHz band and the 5.15-5.25 GHzband. Treat all WLAN channels for J apan uniformly in the spec.
To many task groups running Wait until other TG's finished

WG11 Comments on PAR
I would change the title to reflect the actualfrequency ramge: 4.9-5.05 GHz
Make the change in the title of all documents and alsoedit where needed.
Another standard that currently exists, and whichis called out as needing "modification", is 802.11d.I would guess that this implies it has a "similarscope".
Add a reference to 802.11d.
The PAR indicates that channel selection is one ofthe purposes of the project (item 10). It thengoes on to indicate that 802.11h contains powercontrol features which will be used. There are also channel selection features of 802.11h which isseems to
Change item 12 to be more specific in stating that thechannel selection features of 802.11h will be utilized ifthat functionality is required rather than inventing "yet another channel selection" mechanism.

WG11 Comments on 5 CriteriaThe term "laptops" is too constraining (and isnot a defined term in 802.11).
Change "laptops" to "stations (STAs)".
The statement is made "The PAR will defineonly one radio extension to 802.11a, suchthat laptops can be operated…". As astandards committee are we not interested inhaving ALL 802.11a devices capable of beingoperated?
Replace the term "laptops" with the phrase"802.11a based devices".
The word "laptop" is too restrictive. All WLANdevices should be included instead.
The word "laptops" in section 3(b) of doc IEEE 802.11-02/565r0 should be replaced by "WLAN devices".

Other 802 Comments
802.15 WG Comments (1 Total)Since this band overlaps the public safety band in the US, it would be good
to ensure that the PAR incorporates mechanism to not allow operation of devices in this band while in the US.
SEC Comments (1 Total) We develop standards for world wide use. We should not be developing standards for particular countries. If JIS or some other interested party wishes to develop a "profile" of the 802.11 standard that changes parameters for a particular market that is fine but not appropriate business for 802.The "compatibilty" response in the 5 Criteria is not appropriate. The correct response is that this project will destroy compatibility at the air interface for 802.11

Comment on Formation (1 of 13)Comment1. Too many task groups running. Wait until other TGs finished.
Move to reject the comment with the following response and proceed with no changes to PAR or 5C.
We recognize that plenary and interim meetings are busy periods of time. We deem that proceeding with this activity now is the best course of action. The WG chair will continue to manage the meeting agenda to ensure that no more than four sessions meet concurrently.

Comments on Public Safety (6,7 of 13)Move to accept the comments and add the following text to: 5 Criteria Section 2. COMPATIBILITY
It is known that one of the US Public Safety bands overlaps the newly proposed Japanese WLAN bands. As one method of preventing a STA from becoming a source of interference with the US Public Safety band radios, the Japanese banded 4.9 & 5.0 GHz stations could employ passive scanning and read AP beacon information to determine legal bands before transmitting when operating in infrastructure mode. IBSS operating mode could also present a source of interference, however, it is not allowed in Japan in 4.9 & 5.0 GHz and therefore can be disabled in these new bands. Additional interference mitigation approaches will be considered in the task group
The base stations will not pose a problem since they are individually licensed and configured, while the client radios are not.

Regulatory ScopeProposed response :This project does not impair the CSMA air interface, nor interoperation in US bands, as the
changed behavior is keyed to knowing the country of operation (using ISO/IEC 3166-1:1997 Country codes) as well as the frequency band to attempt communication on. In every regulatory domain known , it is required to know the country of operation before attempting transmission of radio energy (active probing), so that the transmission can be lawful.
The PAR and Five Criteria intend to extend 802.11a to regulatory domains that regulate EIRP rather than Transmit Power, and recommend listening, which FCC and ETSI do not. Japan requires co-adjacent channel power restrictions (two channels away) and restricted modes (Peer-to-peer prohibited) rules that were not envisioned when .11a was created. The Scope of the PAR is limited to Japan, as that bounds the regulations that differ from existing US Part 15 rules and from Project 802.11h's scope.
WG 802.11 could use a maintenance PAR mechanism to address regulatory changes required in other bands or regulatory domains.
Move to use the above response with no document wording changes.Mover: Bruce Kraemer Second: Al PetrickYes 21 No 0 Abstain 14 Motion passes

Comment11. If we amend the IEEE802.11 standard to comprehend interoperating in the new bands at 4.9 and 5.03 GHz in Japan then we should update the standard to comprehend the existing unique channels in Japan - channel 14 in the 2.4 band and channels 34,38, 42 and 46 in the 5.15-5.25 band. It is implied that the requirements for Ch 14 are the same as those for Chs 1-13; that is not the case. Similarly the power and channelization for the 5.15-5.25 band in Japan is not the same as that for the US. In fact, the existing spec only reflects requirements for the US in the 5 GHz band.

Move to submit the following response with no changes to document wording
The PAR does intend to add the channel assignment and etiquette behavior in Japan for the previously allocated 5.15-5.25 band.
The scope of this PAR does not address changes required to meet Japanese regulatory requirements in the 2.4 GHz band.

Channel Selection (13 of 13)
Comment
13. The PAR indicates that channel selection is one of the purposes of the project (item 10). It then goes on to indicate that 802.11h contains power control features which will be used. There are also channel selection features of 802.11h which is seems to me should also be used if that is one of the purposes of the project.
