4. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 4 Comments from Paul Nikolich on PAR Clause 5.2.b: One of the requirements is to maintain or improve power efficiency per station. Power efficiency is defined in the notes, but it is not clear to me what the baseline against it will be assessed. Is it any battery powered device with an 802.11 interface or some subset thereof (e.g. existing 802.11 based devices in and around 60GHz)? [Response] Power efficiency of devices compliant with the project will be compared against the power efficiency of devices compliant with the IEEE 802.11ad- 2012 amendment. We accept your comment and please refer to the updated PAR. Edward Au (Marvell Semiconductor) March 2015

5. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 5 Comments from Paul Nikolich on PAR Clause 5.2.b: Coexistence. Will coexistence with 802.15.3c & d based devices be evaluated? [Response] Yes, coexistence with other systems for license-exempt bands above 45 GHz, including 802.15.3c & d and other future amendments, will be evaluated and documented in Coexistence Assurance document. It is documented in clause 1.1.2 of CSD. Edward Au (Marvell Semiconductor) March 2015

7. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 7 Comments from 802.3 on CSD Clause 1.2.3: The title of the amendment is temporary and irrelevant to the CSD question so the latest sentence of the first paragraph should be deleted. [Response] We accept the comment and delete the latest sentence of the first paragraph. Clause 1.2.4.a): An amendment amends the base standard, not another amendment. Something like “add refinements to” instead of “amend” in the second sentence would be an improvement. [Response] Thank you for your comment. We made the suggested change. Edward Au (Marvell Semiconductor) March 2015

8. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 8 Comments from 802.3 on CSD Clause 1.2.4.b): The answer is not really responsive. This question seeks evidence that technology is sufficiently proven to allow a project to be completed in a reasonable amount of time without need for research, fundamental simulation and modeling. The response indicates that these tasks will be done as part of standards development not as proof of feasibility, leading to the conclusion that it is too early to approve a project. (It is unnecessary to indicate that additional simulation and modeling will be used to validate and refine selected specifications.) [Response] We accept the comment. Please refer to the updated PAR.

10. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 10 Comments from 802.15 on PAR Clause 7.1: 802.11ay looks similar to 802.15.3c and 802.15.3e. Please note similarities and differences. [Response] IEEE 802.15.3c-2009, which is an amendment to IEEE 802.15.3-2003, defines operations in 60 GHz bands with a peak PHY date rate of around 5.8 gigabits per second. The similarities are that both IEEE 802.11ay and IEEE 802.15.3e define operation in license-exempt 60 GHz band. IEEE 802.11ay is differentiated itself from IEEE 802.15.3c that it is the only for 802.11 WLANs that aims to provide data rates in excess of 20 gigabits per second for point- to-point and point-to-multipoint indoor and outdoor usages for license- exempt bands above 45 GHz. Edward Au (Marvell Semiconductor) March 2015

11. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 11 Comments from 802.15 on PAR [Response (Cont’d)] IEEE 802.15 Study Group 3e (SG3e) is established in December 2014, which works on the PHY and MAC amendments of the IEEE 802.15.3 for close proximity high-data rate systems. The similarities are that both IEEE 802.11ay and IEEE 802.15.3e define operation in license-exempt 60 GHz band. The difference is that the primary objective of IEEE 802.15.3e is to enable close-proximity point-to-point communications with a typical range of 10cm or less, mainly to replace physical connection. IEEE 802.11ay, on the other hand, is part of the WLAN network and ecosystem. IEEE 802.11ay defines standardized modification to IEEE 802.11 PHY and MAC for license-exempt bands above 45 GHz and enables point-to-point and point-to-multi-point indoor and outdoor usages with data rates in excess of 20 gigabits per second and a range of 1km, while fully integrated with all other IEEE 802.11 components and standards.

13. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 13 Comments from 802.22 on PAR Clause 2.1 and 5.2.b: It will be great if you can specify what ‘in and around’ means. Recommendation: Remove ‘in and around’ and change to in the 60 GHz Band as defined by the regulatory requirements. [Response] We address this comment and please refer to the updated PAR.

15. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 15 Comments from Annette Reilly (NesCom member) on PAR Clause 2.1: The title of the standard refers to “ultra high” throughput. Could this be replaced with a quantified range of throughput? [Response] Unlike standards related to frequencies or voltages, a quantified range of throughput is hard to know in advance. While the scope of work includes a target figure of 20 gigabits per second, the resulting amendment might do substantially better than that and we expect that the range of throughput will be determined by technologies considered during the creation of this amendment. Building a quantified range of throughput into the title of the amendment now might result in a misleading or misrepresentative title. We are changing the title of the amendment to “Enhanced throughput for operation in license-exempt bands above 45 GHz”. Edward Au (Marvell Semiconductor) March 2015

16. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 16 Comments from Annette Reilly (NesCom member) on PAR Clause 5.5: Is swath rather than swathe what is intended? [Response] We address your comment and change the word to “portion”. Edward Au (Marvell Semiconductor) March 2015

17. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 17 Comments from Osama Aboul-Magd (NesCom member) on PAR Clause 2.1: “Ultra high” needs to numerically defined. [Response] Unlike standards related to frequencies or voltages, a quantified range of throughput is hard to know in advance. While the scope of work includes a target figure of 20 gigabits per second, the resulting amendment might do substantially better than that and we expect that the range of throughput will be determined by technologies considered during the creation of this amendment. Building a quantified range of throughput into the title of the amendment now might result in a misleading or misrepresentative title. We are changing the title of the amendment to “Enhanced throughput for operation in license-exempt bands above 45 GHz”. Edward Au (Marvell Semiconductor) March 2015

18. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 18 Comments from Osama Aboul-Magd (NesCom member) on PAR Clause 5.2.b: Second paragraph: change “shall enable” to “enables”. [Response] “Shall enable” is replaced with “while ensuring”. Edward Au (Marvell Semiconductor) March 2015

19. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 19 Comments from Osama Aboul-Magd (NesCom member) on PAR Clause 7.1 IEEE 802.15.3e PAR seems to be of similar scope. May add to section 7.1. [Response] We accept the comment and include IEEE 802.15.3e as a project with similar scope. Edward Au (Marvell Semiconductor) March 2015

20. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 20 Comments from Osama Aboul-Magd (NesCom member) on PAR Clause 7.1 How this project is different from those identified with similar scopes? [Response] IEEE 802.15.3c-2009, which is an amendment to IEEE 802.15.3-2003, defines operations in 60 GHz bands with a peak PHY date rate of around 5.8 gigabits per second. ECMA TC 48 60 GHz specifies a PHY, distributed MAC sublayer and an HDMI protocol adaptation layer for 60 GHz wireless network that supports a maximum achievable PHY throughput of 6.35 gigabits per second. IEEE 802.15.3d is an ongoing project that defines wireless switched point-to- pint PHY to IEEE 802.15.3 at a nominal PHY data rates of 100 gigabits per second with fallbacks to lower data rates as needed. Operation is considered in both licensed and unlicensed bands from 60 GHz up to and including optical wireless. Edward Au (Marvell Semiconductor) March 2015

21. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 21 Comments from Osama Aboul-Magd (NesCom member) on PAR [Response (Cont’d)] IEEE 802.11aj is an ongoing project in IEEE 802.11 specifically focused on the Chinese market. It defines standardized modifications to IEEE 802.11 PHY and MAC that allows applications to operate in the Chinese 45 GHz and 59-64 GHz frequency bands. IEEE 802.15.3e is established in December 2014, which works on the PHY and MAC amendments of the IEEE 802.15.3 for close proximity high-data rate systems. Their primary objective is to enable close-proximity point-to- point communications with a typical range of 10cm or less. IEEE 802.11ay is different from the aforementioned IEEE 802 wireless standards/projects and ECMA projects in that it is specific for 802.11 WLANs and aims to provide data rates in excess of 20 gigabits per second for point-to- point and point-to-multipoint indoor and outdoor usages for license-exempt bands above 45 GHz. Edward Au (Marvell Semiconductor) March 2015

22. doc.: IEEE 802.11-15/0271r4 SubmissionSlide 22 Comments from Andrew Myles (NesCom member) on PAR Clause 2.1: What is “ultra high”? [Response] Since this project will result in a wireless LAN system with significantly higher throughput than is provided by 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, and 802.11ad wireless networks, the term “ultra high” was used to differentiate itself from other IEEE 802 wireless standards, which stresses the specification of higher throughput wireless LAN technology for license-exempt bands above 45 GHz. Unlike standards related to frequencies or voltages, a quantified range of throughput is hard to know in advance. While the scope of work includes a target figure of 20 gigabits per second, the resulting amendment might do substantially better than that and we expect that the range of throughput will be determined by technologies considered during the creation of this amendment. Building a quantified range of throughput into the title of the amendment now might result in a misleading or misrepresentative title. However, we are changing the title of the amendment to “Enhanced throughput for operation in license-exempt bands above 45 GHz”. Edward Au (Marvell Semiconductor) March 2015
