2. 2 Content  IEEE 1609 Project update  Thinking Beyond IEEE 802.11p Amendment to IEEE 802.11-2007  Supplemental Slides

3. 3 P1609 Project Status Update  IEEE Std 1609.2-2013 - WAVE Security Services –Revision approved, January 2016 –Essential changes determined, need to accommodate results from security studies were by end of 2015 –Additional functionality discussed during February 2016 meeting as an amendment, any planned changes will preserve backward compatibility  IEEE Std1609.3-2010 – WAVE Networking Service –Revisions approved, January 2016  Expect 1609.2-2016 and 1609.3-2016 published copies available within approximately 2 months (by end of April 2016)

4. P1609 Project Status Update -2  1609.0-2013, WAVE Architecture –Published March 2014  Useful guidance about the 1609 family of standards  Harmonization discussions on-going for WSMP and FNTP and respective service announcements  Alignment with NHTSA regulatory decision on Connected Vehicle for V2V deployment  Working Group consensus to submit revision PAR in 2016 to align with changes to 1609.2-2016 and 1609.3-2016 approved in January 2016 4

5. P1609 Project Status Update-3  1609.12-2012, Identifier Allocations –Revision approved January 2016 –Future coordination of allocations required with ISO TC204 WG18, allocations are currently posted to the ISO website, freely accessible –IEEE WG obligation to work with IEEE Registration Authority for registration of PSIDs –Continue to work allocations in ad hoc mode until ISO TC204 or another entity establishes a comprehensive central registry and registry procedures for ITS identifiers, keeping the IEEE RAC advised Note. IEEE Registration Authority Committee (RAC) has first right of refusal for IEEE standards with registration requirements when a global ITS registry is established 5

6. Strategy for Revisions  Beyond FY2015 –Additional bug fixes –Functionality enhancements, that does not to break backward compatibility –Consider pilot deployment site feedback and issues –Cooperate with entities testing devices for conformance –Maintain standards –Consider U.S. Federal Communications Commission (FCC), National Highway Transportation Safety Administration (NHTSA) and other regulatory decisions 6

7. Safety Channel 172  Proposal to develop a standard that addresses difference between DSRC switched channel and “always on” channel on one radio dedicated to Channel 172 (5.855-5.865Hz) in US channel plan  To address upper layer profile, security and channel congestion mitigation features, and identifies lower layer features used  Proposal supported by US CV Program  Priority to include specifications in proposed NHTSA NPRM  Presented, discussed, and accepted in SAE J2735 with a contract editor familiar with 1609 standards 7

8. Consider When Thinking 802.11p  Background –One of the changes that affected IEEE 802.11p was that all primitives that were previously labeled as “OCBEnabled were changed to “OCBActivated” throughout the standard –Primitives that returned no value, or caused nothing specific to happen were deleted, there were at least two of these in IEEE 802.11p-2010 –Any 802.11 feature used has to consider if it can be implemented with no BSS and no AP, according to 802.11p  Specifying “OCBActivated=True” is necessary, but not sufficient to define WAVE/DSRC operation in 802.11™-2012  Selection of which PHY to use may have to incorporate the required parameters from regulatory tables in the annexes  Awareness of adjacent channel and alternate adjacent channel interference, and selecting appropriate transmission masks 8

9.   IEEE 802.11p amendment defines the timing advertisement frame use and other management frames and not beacon frames   Building a radio that uses the OFDM PHY, the 802 MAC, using several management frame types, and operates without a beacon covers quite a bit of a very large standard   Each change to the base standard when amendments are incorporated may have to be evaluated – –Amendment 802.11ai, Fast Initial Link Setup (FILS), may fill gaps in ITS use – –Latency reduction and scalability potentially offered by FIA would enable many public sector, commercial, and public transit IP-based applications that could leverage off of 802.11p-based devices that may become OEM equipment in the future – –Both USA and Europe have ITS spectrum allocations in 5.9 GHz band to support both sets of applications (low-latency safety of life and IP-based) 9 Consider When Thinking 802.11p
