  1. Sub 1 GHz PAR comment responses Authors: Date: 2010-07-13 David Halasz, Aclara

  2. The following are responses to the IEEE 802.11 S1G PAR review comments received on 10/0001r8. The comments received are in submission 10/0871r1. The changes to the PAR are in 10/0001r9. Abstract David Halasz, Aclara

  3. 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 Comment 1 from James Gilb David Halasz, Aclara

  4. 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 Comment 2 from IEEE 802.15 Working Group David Halasz, Aclara

  5. Comment 3.1: I disagree with the 802.11 S1G 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 Comment 3 from Roberto Aiello David Halasz, Aclara

  6. Comment 3.4: recommend that the scope includes co-existence requirements with 802.15.4g at 900MHz • 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 Comment 3 from Roberto Aiello David Halasz, Aclara

  7. Comment 4.1: The PAR should clearly reference Utility requirements - until the 5c 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 1GHz“ • Decline: S1G focusing on OFDM Comment 4 from IEEE 802.15.4g David Halasz, Aclara

  8. 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 900MHz 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. Comment 4 from IEEE 802.15.4g David Halasz, Aclara

  9. 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, 802.15.4c, 802.15.4d and 802.15.4g systems" • there should be a limit to the bandwidth used by each channel within the band, for example "not to exceed 1.2MHz" • 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 802.15.4g common signalling mode • Counter: The CA document statement has been strengthened Comment 4 from IEEE 802.15.4g David Halasz, Aclara

  10. 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 802.11af Comment 5 from IEEE 802.22 WG David Halasz, Aclara

  11. Comment 5.2: Section 8.1 - Please replace "P802.11af is limited to the TV White Space. This PAR is for other license-exempt bands below 1 GHz, excluding the TV White Space" with "P802.11af 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 Comment 5 from IEEE 802.22 WG David Halasz, Aclara

  12. Comment 5.3: Please specify all the targeted bands below 1-GHz band where these systems are likely to operate • Accept: These are now called out in the scope • Comment 5.4: Please specify the transmission distances / range over which these systems will operate • Accept: These are now called out in the scope Comment 5 from IEEE 802.22 WG David Halasz, Aclara
