Technical considerations remain primary focus
Don’t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets.
Don’t discuss the status or substance of ongoing or threatened litigation.
Don’t be silent if inappropriate topics are discussed… do formally object.
If you have questions, contact the IEEE-SA Standards Board Patent Committee Administrator at or visit
See IEEE-SA Standards Board Operations Manual, clause and “Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy” for more details.

November 2016
doc.: ec EC
Participation in IEEE 802 Meetings
Participation in any IEEE 802 meeting (Sponsor, Sponsor subgroup, Working Group, Working Group subgroup, etc.) is on an individual basis
• Participants in the IEEE standards development individual process shall act based on their qualifications and experience. ( section 5.2.1)
• IEEE 802 Working Group membership is by individual; “Working Group members shall participate in the consensus process in a manner consistent with their professional expert opinion as individuals, and not as organizational representatives”. (subclause “Establishment”, of the IEEE 802 LMSC Working Group Policies and Procedures)
• Participants have an obligation to act and vote as an individual and not under the direction of any other individual or group. A Participant’s obligation to act and vote as an individual applies in all cases, regardless of any external commitments, agreements, contracts, or orders.
• Participants shall not direct the actions or votes of any other member of an IEEE 802 Working Group or retaliate against any other member for their actions or votes within IEEE 802 Working Group meetings, see section and the IEEE 802 LMSC Working Group Policies and Procedures, subclause “Chair”, list item x.
By participating in IEEE 802 meetings, you accept these requirements. If you do not agree to these policies then you shall not participate.

11. Collaboration with 802.21 AR/VR Vertical Applications
'Network Enablers for Seamless HMD-based VR (Virtual Reality)’
Dillon Seo
Presentation to TSN May interim
802.11be will address AR/VR use cases
Tim Godfrey, EPRI

12. Goals for AR/VR collaboration in 802.24
AR/VR is an identified vertical application for Smart Grid (electric utilities) for field force, safety, and training
will liaise to other WGs if they develop amendments to their standards to support low latency.
The low-latency white paper will provide input on requirements to WGs
Vertical Application areas can provide input on specific use cases
Include representatives from related activities in other WG’s: TSN, be, e
will provide a venue for collaboration (joint meetings)
Build on Low Latency White Paper
Broadly define the set of applications (vertical and otherwise) around bounded / low latency
Look at the VR architecture diagram and consider the appropriate standard for each link. They will be a mix of wireless and wired.
In current white paper, latency limit is 5mS. Combination of wired/wireless.
Some use case may incorporate a WAN.
Existing testing shows challenges exceeding two hops (switches) in a network
IEEE 802 could provide comparable services to what is promised by 5G.
Tim Godfrey, EPRI

13. Discussion What are the key requirements for QoE for AR/VR?
Are latency and jitter separate?
Motion to Photon latency – 20mS Upper Bound
Jitter doesn’t really matter if latency bound is met
Dillon: Need for this work in IEEE 802 is based on prohibitive cost of serving these applications over commercial cellular
Consider an IEEE 802 scenario using existing standards:
802.1 TSN with 10G Ethernet, and ac, ad, or ax
Identify gaps and contribute to be as a proposed requirement.
Need to ensure that TSN end-to-end mechanisms can be adopted into
scenario with moving train – between heterogeneous networks
Tim Godfrey, EPRI

14. Next Steps 802.21 to provide text contributions
Goal is to have the real time white paper by 2020?
Bring together various working groups to solve issues for VR and performance.
Application space is driven by ever increasing resolution. Target HDMI 1.2 specification. Resolution and frame rate drive data rate. Can it be compressed?
This can be seen as alternative to 5G approaches, but standards-based and lower cost to use.
Show how Wi-Fi technology can provide an equally good or better result and performance (bandwidth and low jitter and low latency)
Map identified uses cases on to various IEEE 802 standards.

Influence be or other groups working in low-latency areas
Outreach to other standard groups
Review progress since meeting:
Dillon will take white paper “ a-white-paper-on-use-cases-and-requirements-for-supporting-hmd-based-vr-applications” and use as source text for next revision of White Paper draft “ low-latency-communication-white-paper”
Check with Alan Jones to see if there is an interest in creating a contribution based in RTA TIG output.
Tim will take some use cases from TSN white paper for utility applications
Consider a section to distinguish between latency and jitter implications.
Low latency also has implications on reliability, predictability, etc
Notes captured into draft: Current Draft r2
Tim Godfrey, EPRI

26. g and ah Coexistence ( )
will develop a whitepaper/document for application-specific use cases. Identifying where each standard is most suitable, and how to make best use of other changes.
Identify use cases where g is not sufficient and both are needed
Could be choices of applications, channel guidelines, duty cycle,
Avoid perception that 802 standards are unable to coexist
Evaluate and describe potential application-level implications of delay/latency increases due to mutual interference
