July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 1 from James Gilb • Accept – The scope has been replaced for clarification. – Included in the scope clarification are, • Target range • Target data rate • Usage of the IEEE 802. 11 MAC with only changes to support the PHY • Target application Submission Slide 3 David Halasz, Aclara

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 2 from IEEE

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 2 from IEEE 802. 15 Working Group • Accept – The scope has been replaced for clarification. – Included in the scope clarification are, • Target range • Target data rate • Usage of the IEEE 802. 11 MAC with only changes to support the PHY • Target application Submission Slide 4 David Halasz, Aclara

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 3 from Roberto

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 3 from Roberto Aiello • Comment 3. 1: I disagree with the 802. 11 S 1 G PAR because it is too vague – Accept: The scope has been clarified • Comment 3. 2: I recommend that the PAR specifies: data rates, and outdoors or indoors operation – Accept: These are called out in the scope • Comment 3. 3: I recommend that the PAR specifies: simultaneous operation for at least 3 co-located orthogonal networks – Counter: The CA document statement has been strengthened Submission Slide 5 David Halasz, Aclara

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 3 from Roberto

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 3 from Roberto Aiello • Comment 3. 4: recommend that the scope includes coexistence requirements with 802. 15. 4 g at 900 MHz – Accept: The CA document statement has been strengthened • Comment 3. 5: recommend that the scope explicitly states that the amendment is to create a new PHY for 802. 11, not limited to re-banding existing 802. 11 PHY, so that the best PHY to meet the application requirements can be specified. References to 802. 11 OFDM operation in 5. 5 should be removed. – Counter: New OFDM PHY Submission Slide 6 David Halasz, Aclara

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 4 from IEEE

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 4 from IEEE 802. 15. 4 g • Comment 4. 1: The PAR should clearly reference Utility requirements - until the 5 c clearly defines how the requirements of the Smart Grid are addressed by this PAR, this particular application should be excluded. – Counter: Removed references to Smart Grid • Comment 4. 2: Suggest removing from 5. 5 of the PAR the requirement for " OFDM " from " OFDM operations below 1 GHz“ – Decline: S 1 G focusing on OFDM Submission Slide 7 David Halasz, Aclara

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 4 from IEEE

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 4 from IEEE 802. 15. 4 g • Comment 4. 3: If OFDM remains, then there should be a better justification concerning the use of current proven indoor technology for outdoors in the 900 MHz band. – Accept: OFDM remains. But acknowledge that the OFDM PHY will need to be changed for outdoor operation in new bands and with new channelization. The scope is not limited to the current IEEE 802. 11 OFDM PHY. Submission Slide 8 David Halasz, Aclara

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 4 from IEEE

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 4 from IEEE 802. 15. 4 g • Comment 4. 4: • We recommend including a stronger coexistence statement: – "Provides mechanisms that enable coexistence with other systems in the band including IEEE 802. 15. 4 -2006, 802. 15. 4 c, – – – 802. 15. 4 d and 802. 15. 4 g systems" there should be a limit to the bandwidth used by each channel within the band, for example "not to exceed 1. 2 MHz" simultaneous operation for at least 3 colocated orthogonal, non-interfering networks in the same band is a Smart Grid requirement. support of well-behaved coexistence method such as the 802. 15. 4 g common signalling mode – Counter: The CA document statement has been strengthened Submission Slide 9 David Halasz, Aclara

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 5 from IEEE

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 5 from IEEE 802. 22 WG • Comment 5. 1: Please replace the words "TV White Spaces" with words "TV frequency bands" in the Scope and the Purpose – Declined: We used “TV White Space” since this is the term used by IEEE 802. 11 af Submission Slide 10 David Halasz, Aclara

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 5 from IEEE

July 2010 doc. : IEEE 802. 11 -10/0878 r 0 Comment 5 from IEEE 802. 22 WG • Comment 5. 2: Section 8. 1 - Please replace "P 802. 11 af is limited to the TV White Space. This PAR is for other license-exempt bands below 1 GHz, excluding the TV White Space" with "P 802. 11 af is limited to the TV White Space. This PAR is for other license-exempt bands below 1 GHz, excluding the TV frequency bands. “ – Counter: We deleted the extra explanation and clarified the explanation in 7. 1 Submission Slide 11 David Halasz, Aclara
