  3. 802.15.4n PAR • 2.1 Title: Standard for Local and metropolitan area networks--Part 15.4: Low-Rate 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 Jon Rosdahl, (CSR)

  4. Comments on 802.15.4n PAR • 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,” Jon Rosdahl, (CSR)

  5. 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) Jon Rosdahl, (CSR)

  6. 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. Jon Rosdahl, (CSR)

  7. 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. Jon Rosdahl, (CSR)

  8. 802.15.4p PAR 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…. Jon Rosdahl, (CSR)

  9. 802.21d PAR 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. Jon Rosdahl, (CSR)

  10. 802.3bk Jon Rosdahl, (CSR)

  11. 802.1AX-Rev Jon Rosdahl, (CSR)

  12. 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? Jon Rosdahl, (CSR)

  13. 802.1AEbw Jon Rosdahl, (CSR)

  14. 802.1Xbx 4.2 and 4.3 the time for doing sponsor ballot seems too short. NesCom generally expects as a minimum 6 months between dates. Jon Rosdahl, (CSR)

  15. 802.1Qbv Jon Rosdahl, (CSR)
