2.1 Title: Standard for Local and metropolitan area networks--Part 15.4: LowRate Wireless Personal Area Networks (LR-WPANs) Amendment: Physical
Layer Utilizing Dedicated Medical Bands in China
5.2 Scope: This amendment defines a physical layer for IEEE Std. 802.15.4
utilizing the approved 174-216 MHz, 407-425 MHz and 608-630 MHz
medical bands in China. This amendment defines modifications to the Medium
Access Control (MAC) layer, if any, needed to support this new physical layer.
5.4 Purpose: This document will not include a purpose clause.
5.5 Need for the Project: The Chinese Radio Administration committee has
approved the 174-216 MHz, 407-425 MHz and 608-630 MHz bands for
medical information transmission. IEEE Std. 802.15.4 has always supported
operation in appropriate frequency bands and an opportunity is now available
to extend the operation of IEEE Std. 802.15.4 into the bands approved for
Chinese medical use. It is a good extension to amend the IEEE Std. 802.15.4
standards for MBAN systems using devices in the above Chinese medical
bands. This Project will define an alternate PHY and the necessary
modifications to the MAC that are needed to support the PHY operation
according to the Chinese Radio Administration rules doc. # 423-2005 in the
Chinese medical bands.
5.6 Stakeholders for the Standard: The stakeholders include medical
equipment manufacturers, patients and healthcare providers both within
hospitals and in residential environments along with service providers that
offer remote support facilities

Title: Add numeric range for band
Title: Is 802.15 using a new short version of titles?
5.2 Scope: delete “, if any, “
5.5 Need: Check title of Chinese Regulator reference. (Expected to see a SRRC
reference)
5.5 expand first use of Acronym “Medical Body Area Network (MBAN)”
5.6 Stakeholders: Suggested replacement: “The stakeholders include medical
equipment manufactures, patients and healthcare providers both within hospitals
and in residential environments. Stakeholders also include remote support
facilities service providers.
7.1: delete “Technically the answer is no, but”
7.1: change “15.j” to “IEEE P802.15.4j”
7.1: remove the “P” from “P802.15.16” and note that “IEEE Std.” is missing from
the Project Standard Number field and in the Project title. Add “IEEE Std.” to
“802.15.16” appears. (2 times)
7.1 Add a “IEEE P” to “802.15.4j” appears 3 times.
8.1: The Note for 5.2 would be better as part of the Coexistence statement in the 5c.
And 7.1 is more appropriate for Unique Identity in the 5c. Delete both paragraph
1 and 2.
8.1 Add “7.1” prior to paragraph 3, and change the “P802.15.6” to “IEEE Std.
802.15.6” and change “15.4” to “IEEE Std. 802.15.4”
8.1 Add “7.1:” prior to paragraph 4, and change “is a similar amendment to 15.4n”
to “is similar to this amendment,”

802.15.4n 5C comments
1.a) Change “802.15.4” to “IEEE Std. 802.15.4” or Delete
“802.15.4 is already used for this”.
Change “802.15.4/LR-WPAN” to IEEE Std.
802.15.4” Change “Industries” to “industries”.
Expand first use of LR-WPAN or replace with “IEEE
Std. 802.15.4”
3.a) change “in these” to “in the”
Coexistence: A Coexistence Assurance document is
needed even if it is a very short one that states the
information listed here…
5 a) this does not make sense. Rewrite. Look at using text
from b)

802.15.8 PAR
• 4.3 consider submission date to RevCom being at least
Oct 2015, but March 2016 may be more realistic.
• 5.2: change “defines the PHY” to “defines PHY”,
change “specification” to “mechanism”
• 5.4: break into succinct sentences
• 5.5: Listed in Need, but not in Scope: “proximity
awareness, Signaling overhead reduction”….things in
the Need statement should probably be in the Scope
statement if planning to meet the need.
• 5.6 Change “Content/Internet” to two separate lines
• 8.1 these paragraphs do not really add to the PAR
delete them or move to 5C.

802.15.8 PAR: Scope
• Proposed replacement for Scope statement (collapse the bulletlist to
sentence fragments):
• This standard defines PHY and MAC mechanisms for Wireless
Personal Area Networks (WPAN) Peer Aware Communications (PAC)
that are optimized for peer to peer and infrastructureless
communications with fully distributed coordination.
• PAC features will include:

discovery for peer information without association;
discovery signaling rate of greater than 100 kbps;
discovery of the number of devices in the network;
scalable data transmission rates up to 10 Mbps;
group associations with simultaneous membership in up to 10 groups;
relative positioning;
multihop relay;
security;
proximity aware; signaling overhead reduction;
and operational in selected globally available unlicensed/licensed
bands below 11 GHz capable of supporting these requirements.

5.2
• typo: PHYsical should probably be Physical.
• Insert “Std.” to IEEE 802.15.4….
• typo: lower case the Medium Access Control….
• What is the range of the channel Bandwidth limits?
• Consider changing “accommodates transmit power levels greater
than the 1 watt typical of US FCC Part 15 devices” to indicate the
standard that you will actually be using (are you targeting Part 80
and/or Part 90 devices?)
• Change “and to meet United States” to “, primarily to meet United
States”
• And delete “and similar regulatory requirements in other parts of the
world.”
5.5 Insert “Std.” to IEEE 802.15.4….

4.2 and 4.3 not enough time for Sponsor Ballot indicated.
5.2 Is multicast and group the same thing? So the parsing of the
sentence is a bit confusing.
• Suggested change to Scope statement:
This amendment defines support for: group management using
multicast frames, handover of users from one group to another in the
same access network, and secure multicast MIH (Media-Independent
Handover) protocol exchange.
5.4 suggest that you move the first 2 sentances to 5.5, and put “this
amendment will not contain a Purpose Statement”.
5.5 Add text from 5.4.
• insert “Std.” to “IEEE 802.15.4”
• Check that the proper version of the PAR is being used.

802.1Qbu
5.2: Should “the transmission of the preempted frame”
really be “the transmission of the preempted frames”?
Singular seemed incorrect.
5.3 Would other 802 WGs need to provide “support of
pre-emptive forwarding in MAC Services” for end
stations? Why only 802.3?
5.3 Why should this PAR start prior to 802.3 being ready
to start?

4.2 and 4.3 the time for doing sponsor ballot seems too
short. NesCom generally expects as a minimum 6
months between dates.
