2. doc.: IEEE 802.11-02/759r0 Submission November 2002 Bruce Kraemer, Intersil TK Tan, PhilipsSlide 2 Background  In September, Japan allocated new spectrum for WLAN below 5GHz 4.9 to 5.0 & 5.03 to 5.091  Great opportunity for 802.11a but requires amendment  Development of PAR & 5C undertaken by WNG SC rather than creating a new SG

6. doc.: IEEE 802.11-02/759r0 Submission November 2002 Bruce Kraemer, Intersil TK Tan, PhilipsSlide 6 Comments on 5 Criteria (3,4,5 of 13) Comments 3. The word "laptop" is too restrictive. All WLAN devices should be included instead. 4.The statement is made "The PAR will define only one radio extension to 802.11a, such that laptops can be operated…". As a standards committee are we not interested in having ALL 802.11a devices capable of being operated? 5. The word "laptop" is too restrictive. All WLAN devices should be included instead.

7. doc.: IEEE 802.11-02/759r0 Submission November 2002 Bruce Kraemer, Intersil TK Tan, PhilipsSlide 7 5 Criteria wording (3,4,5 of 13) 3b) One unique solution per problem (not two solutions to a problem). The PAR will define only one radio extension to 802.11a, such that laptops can be operated in 4.9 GHz, 5.0 GHz as well as 5.15-5.25 GHz. The PAR will define only one radio extension to 802.11a, such that WLAN devices can be operated in 4.9 GHz, 5.0 GHz as well as 5.15-5.25 GHz. Move to accept the comments and replace the word “laptops” with “WLAN devices”. Mover: Bruce Kraemer Second: Kazuhiro Okanoue Yes 30 No 0 Abstain 2 Motion passes

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. 7. The 4.9 GHz band is allocated for public safety use in the US. I am concerned that Japanese laptops with 802.11a cards may be used in ad hoc mode in the US by visitors and may interfere with public safety radios.

9. doc.: IEEE 802.11-02/759r0 Submission November 2002 Bruce Kraemer, Intersil TK Tan, PhilipsSlide 9 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.

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.

11. doc.: IEEE 802.11-02/759r0 Submission November 2002 Bruce Kraemer, Intersil TK Tan, PhilipsSlide 11 Channel Selection (13 of 13) Response Move to accept the comment and provide the following response with a associated change to the PAR Section 15. The power control and channel selection mechanisms in 11h (draft) seem to be applicable for use and may be extended to the new channels. Current wording There are extensions in the 802.11 TGh draft for power control that will be used in this project. New wording The 802.11 TGh draft has power control and frequency selection mechanisms that may be used in this project. Mover: Bruce Kraemer Second: Kazuhiro Okanoue Yes 27 No 0 Abstain 10

12. doc.: IEEE 802.11-02/759r0 Submission November 2002 Bruce Kraemer, Intersil TK Tan, PhilipsSlide 12 Motion  Move that the WG approve the revised PAR (11-02-564r3) and 5 Criteria (11-02- 565r1) and forward them, with comment resolution responses (11-02-668r3), to the SEC for approval on Friday Nov 15 ‘02.
