4. 802.15.3d 100Gbps wireless switched point-to-point physical layer, PAR and CSD 5.2.a and 5.2.b The scope is not bounded sufficiently.

5.2a and 5.2b Stakeholders will not be able to determine if this is a project if of interest with the scope as written.

5.2a and 5.2b It would seem that this project may overlap other projects .

5.2.b – The scope is not defined to a range that is definitive. Remove “or more” as a start, but the scope would need to be defined more crisply.

5.5 The last sentence is not true. (i.e. 802.11ad)

5.5 “guaranteed” is not possible when using unlicensed wireless bands.

5.1 Would you check the number that is actively involved? 100 seems high (only 20 people from 11 organizations attended the Study Group in January)

7.1 – There would seem to be some projects of similar scope – i.e. 802.15.3c, 802.11ad, Transferjet, etc.

General Question – Is this the project that is getting the .1AC MAC address space correction?

General: The CSD includes a suggested range of “up to several 100m”

1.2.1 a) “guaranteed” – this is not possible – reword sentence.

1.2.1 a) The use cases seem too broad to be believable.

1.2.2 – Is 48-bit addressing required to be conformant with 802.1AC, if so, is this PAR proposing to use 48-bit addressing?

1.2.5 Is the proposed application consistent with modern data centers? Does this apply more to older deployed data centers for retro upgrade? If the data center is wired up, the change of configuration is typically done via software. So does this wireless technology provide a benefit given the wired connectivity?

• This statement does not seem to indicate a distinct identity, but rather a change to the radio being used.

• “needs of IEEE 802.15.4” - the standard has not the “need” but rather the users of the standard.

• Could this statement simply be that you are adding ranging to your 802.15.4 radio?

General – This seems to be a word document that does not capture the correct PAR format. Please put into myProject and allow it to generate the proper output file to give the correct change bars and edit changes.

2.1 Title – dropping the TV from the “TV bands” leaves the title without bound of the frequencies being used. Suggest add “bands between 1300 MHz to 1750 MHz, 2700 MHz to 3700 MHz and 54 MHz to 862 MHz. “ to the title to ensure people know what this standard is covering.

7.1 802.11af should be lower-case.

8.1 the text there does not belong – it does not indicate which section it is giving extra explanation to.

Delete all the text in 8.1 – consider adding to CSD or to section 5.5 Need for project.

Use approved CSD form:

CSD 1.2.2 – missing template or question…not from the approved template?

CSD 1.2.4 missing template or question…not from the approved template?

CSD 802.11af should be lowercase letters. Change all instances.

CSD 1.2.4 last sentence does not parse correctly . Look at how this “802.22 (Wi-Far)” is described.

7. 802.1Qcd Par Modification5.2b – this section does not read correctly.

The “Minor addition” seems like an editorial instruction or an informative word that should be removed.

Are you changing the scope of the project as shown in both paragraphs in 5.2b?

Is the scope change just the addition of the new text .

It seems to be a summary for the scope of the project (potentially) or if it is the incremental addition to the scope, then just rewrite the scope of the project as such.

8.1 -- PAR modification form requires a statement of what and why (rationalization) the PAR is being changed be included in 8.1. Please add.

Comment Text in PAR/CSD Remarks / Answers to the Comments

In response to the comments from IEEE 802.11:

PAR 5.2.a and 5.2.b The scope is not bounded sufficiently.

PAR 5.2a and 5.2b Stakeholders will not be able to determine if this is a project if of interest with the scope as written.

PAR 5.2a and 5.2b It would seem that this project may overlap other projects

PAR 5.2.b – The scope is not defined to a range that is definitive. Remove “or more” as a start, but the scope would need to be defined more crisply.

General: The CSD includes a suggested range of “up to several 100m”

5.2.a. Scope of the complete standard: This project will define the PHY and MAC specifications for high data rate wireless connectivity with fixed, portable and moving devices. Data rates will be high enough to satisfy a set of consumer multimedia industry needs, and to support emerging wireless switched point-to-point applications.

5.2.b. Scope of the project: This amendment

defines a wireless switched point-to-point

physical layer to IEEE Std. 802.15.3 operating

at PHY data rates typically in the range of 1

Gbps at the low end, and up to 100 Gbps at

the high end. Operation is considered in bands

from 60 GHz up to and including optical

wireless at ranges as short as a few

centimeters and up to several 100m.

Additionally, modifications to the Medium

Access Control (MAC) layer, needed to

support this new physical layer, are defined.

8.1 Additional Explanatory Notes (Item Number and Explanation): 5.2b: In this context the term switching is used to describe the reconfiguration of a set of elsewise fixed wireless links. This means that the physical beams of a device at one end of the wireless links are switched between stationary devices at the other end of the links resulting in an different configuration.

5.2.a, various comments: This is the general scope of 802.15.3, which was cleaned up a bit to remove language and references that might have been helpful 11 years ago, but are just irrelevant or confusing today.. Our Proposal is to leave it as is for now and address it in more detail in the next revision of 15.3

5.2.b, various comments: In response to your comments we have made edits to 5.2b and in 8.1 to clarify the differentiation with other existing standards or projects. These are shown to the left.

General comment: For the backhauling/fronthauling application ranges of several 100m are suitable. We have also added this range to the scope 5.2b of the PAR.

PAR 5.5 The last sentence is not true. (i.e. 802.11ad)

PAR 5.5 “guaranteed” is not possible when using unlicensed wireless bands.

5.5 Need for the Project: In data centers

wireless links will make frequent

reconfiguration easier and more cost-

effective. In the case of backhaul and

fronthaul, wireless solutions will reduce

costs for the case when installing a fiber

network is not cost-effective. In the cases

of close-proximity kiosk-downloading and

intra-device communication, a minimum

data rate achievable with high probability

is required, which should be possible

because of the operation in a controlled

environment. No wireless standard with all

these properties within the whole range of

targeted data rates from 1 to 100 Gbps

suitable for operation in a switched point-

to-point-configuration exists today.

Adding a sentence to 8.1: In close proximity kiosk-downloading the link distance is at the order of a few centimeters.

5.5, various comments: In response to your comments, we have made the edits to 5.5 and 8.1 shown to the left

PAR 5.1 Would you check the number that is actively involved? 100 seems high (only 20 people from 11 organizations attended the Study Group in January)

5.1 Approximate number of people expected to be actively involved in the development of this project: 100

802.15 has typically used the average number of WG voting members in the response to this question.

802.15.3 new proposed scope

Scope:

This amendment defines a wireless switched point-to-point physical layer to IEEE Std. 802.15.3 operating at a PHY data rates typically in the range of 1 Gbps at the low end, and up to 100 Gbps at the high end with fallback to lower dates rates as needed. Operation is considered in bands from 60 GHz up to and including optical wireless at ranges as short as a few centimeters and up to several 100m. Additionally, modifications to the Medium Access Control (MAC) layer, needed to support this new physical layer, are defined.

• 802.22 Response: 802.22 WG Rejects this comment. We believe that we have provided the frequency range in Section 5.2, the Scope. Also as required by the NESCOM convention, the Title is within the Scope. As such, this standard is going to be used in the Bands that Allow Spectrum Sharing in which Communications Devices may Opportunistically Operate in the Spectrum of a Primary Service. This bounds the scope for this project.

It seems to be a summary for the scope of the project (potentially) or if it is the incremental addition to the scope, then just rewrite the scope of the project as such.

Response: Yes we are changing the scope of the project. They changed the way the system generates a PAR modification. It used to show the old text on the left and the new text on the right with the changes highlighted. Now it shows the new scope in plain text on the left and change marked on the right so the contents of both boxes is the same.
