10. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 10 The 802.11 WG has developed questions related to the proposed 802.21 Emergency Services project –The 802.21 WG has proposed a PAR and 5 criteria for Emergency Services 21-09-0027-r6 PAR and 5CPAR and 5C –The 802.11 WG has reviewed these documents and have developed variety of questions for consideration by the 802.21 WG –This document lists those questions

11. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 11 What are the specific requirements being addressed (by regulatory domain)? Situation –5.4 defines a purpose for the proposed standard that includes references to requirements related “Next Generation E911”, “Emergency Alert Broadcast” and “Authority to Authority” Complication –However, nowhere does the PAR or 5 criteria provide references to any documents that specify these requirements or associated regulations –This makes it difficult to measure the success of the project. Question/comment –What are the specific requirements or regulations that this project is proposed to satisfy? –How do these requirements or regulations vary in different regulatory domains?

12. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 12 Is a new MAC and PHY in scope … or not? Situation –5.2 defines the scope of the proposed standard, including a statement that the project will not include a new MAC and PHY Complication –However, 5.5 states that they will provide new PHY and MAC functionality Question/comment –WG21 proposed changes to the WG11 PHY are not acceptable. Remove suggested or implied PHY changes from the PAR scope and purpose.

13. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 13 How can the project goals be achieved without changing 802.3/11/15/16/20/22 Situation –5.5 states that the project will provide new PHY and MAC functionality, presumably in 802.3/11/15/16/20/22 Complication –However, it is not within the scope of 802.21 to make changes to any of these standards Question/comment –How is it intended that the project accomplish the provision of new PHY and MAC functionality without changing any existing MAC or PHY, or defining a new MAC and PHY?

14. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 14 What does “parity with traditional emergency service transport functions” mean? Situation –5.5 states that the project will achieve “parity with traditional emergency service transport functions” Complication –However, it is unclear what this means given “traditional emergency service transport functions” is not defined –It is also not clear that parity can even be achieved between a system based on 802.11 in unlicenced spectrum (for example) and traditional wire-line and cellular systems Question/comment –How is “traditional emergency service transport functions” defined? –What does “parity” mean in this context? We suggest “sufficiency” as a substitute because providing parity with circuit switched or licensed band services is not achievable when using unlicensed spectrum.

15. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 15 What about ECRIT … ? Situation –7.1 states that there are no other projects or standards with similar scope Complication –However, IETF ECRIT is a project with a scope that is arguably greater that the proposed scope of this project Question/comment –Why was ECRIT not referenced? –Have the layer 2 requirements implied by ECRIT been considered in developing this project proposal? –Please identify any functionality or interfaces that 802.21 ES could provide at layer 2 that would support ECRIT at layer 3?

16. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 16 Does the project have measurable goals that can be achieved within three years? Situation –It is “best practice” to define a project for a new standard such that it is able to be meet measurable goals within three years Complication –However, this PAR and 5 criteria does not define any measurable goals and it is unclear whether it can be done within three years Question/comment –Please define measurable goals? –Please explain how the scope of the project is such that it can be completed within three years? –Given the vagueness of the goals of the proposed project, why haven’t you considered defining a recommended practice?

17. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 17 What work is the WFA undertaking? Situation –In the 5 criteria in the broad market potential section it is claimed “This proposed standard may simplify changes currently under consideration by external organization such as IETF ECRIT, WiFi Alliance and WiMAX Forum Complication –However, the WFA has not announced any such work Question/comment –Please justify the claim? –Have the WMF announced any such work?

18. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 18 PAR Project Scope Situation –The current PAR scope is too broad and should focus on the highest priority, shortest to market objective Complication –It is believed that addressing “citizen-to-authority (e.g. packet data encoded 911/112 calls), authority-to-citizen (e.g. emergency alert broadcasts for weather or tsunami) and authority-to-authority (e.g. priority override)” (Scope 5.2) in the same project is too grand an undertaking. Question/comment –We support pursuing exclusively the citizen-to-authority project only in this PAR

19. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 19 PAR Wording The current wording of the scope statement reads: 5.2 Scope of Proposed Standard: This standard will define mechanisms that support compliance within IEEE 802 to civil authority requirements for local and national emergency services such as citizen-to- authority (e.g. packet data encoded 911/112 calls), authority-to-citizen (e.g. emergency alert broadcasts for weather or tsunami) and authority-to-authority (e.g. priority override). This project does not propose a new MAC and PHY. Wording normally acceptable to NesCom /Standards Board might be: 5.2 Scope of Proposed Standard: This standard defines mechanisms that support compliance within IEEE 802 to civil authority requirements for local and national emergency services such as citizen-to- authority (e.g. packet data encoded 911/112 calls), authority-to-citizen (e.g. emergency alert broadcasts for weather or tsunami) and authority-to-authority (e.g. priority override). 5.2 & 5.4 should address the document specifically. 5.5 should address the need for the project and may include restrictions on the group.

20. doc.: IEEE 802.11-09/0778r1 Submission July 2009 Bruce Kraemer (Marvell), Jon Rosdahl (CSR)Slide 20 Where should the work be done? Situation –The 802.21 WG current scope and name is limited to handover Complication –It is recognised that the proposed emergency services project is outside the scope of 802.21 as currently named and understood Question/comment –Is the proposed emergency services project within the scope of 802.21? –Would the proposed work better suited to some other 802 WG?
