Don’t discuss specific license rates, terms, or conditions.
Relative costs, including licensing costs of essential patent claims, of different technical approaches may be discussed in standards development meetings.
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

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.

10. Collaboration with 802.21 AR/VR Vertical Applications
'Network Enablers for Seamless HMD-based VR (Virtual Reality)’
Presentation of contributions
r0 VR Display Specification
r0 White Paper on Use Cases and requirements for supporting HMD-based VR Applications
Tim Godfrey, EPRI

11. 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

12. 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

13. 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.
Tim Godfrey, EPRI

14. Discussion Notes
