  8. Monday 802.24.1 Smart Grid TG Tim Godfrey, EPRI

  9. Collaboration with 802.21AR/VR Vertical Applications • 'Network Enablers for Seamless HMD-based VR (Virtual Reality)’ • Subir Das • 21-19-0009-01-0000 Was presented in 802.11 and 802.15. Subject of discussion • Vertical Applications Collaboration Opportunities • Relates to activities in Real-time. • New activity just starting on Real Time (by Oliver Holland) • Will include text contributions in March 2019. • 802.11 RTA has moved into EHT Task Group • 802.21 will provide use cases for VR into the Real-Time White Paper • 802.21 white paper already written. Includes data on 802.11ay Tim Godfrey, EPRI

  10. Goals for AR/VR collaboration in 802.24 • IEEE 802 can create a community for developing a suite of capabilities suited for this class of applications • Moving the focus from maximizing throughput only to also consider quality of experience and reliability. • Build on 802.24 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

  11. Goals for AR/VR collaboration in 802.24 • 802.21 plans to provide the services layer above the MAC/PHY • AR/VR is an identified vertical application for Smart Grid (electric utilities) for field force, safety, and training • 802.24 will liaise to other WGs if they develop amendments to their standards to support RTC. • 802.21 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 • 802.24 will provide a venue for collaboration (joint meetings) at Plenary Tim Godfrey, EPRI

  12. 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. Resolultion 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

  13. Liaison with IEC SEG8 • Scope of SEG8: • Assess, provide an overview and prioritization of the evolution of technical development and standardization in the field of communication technologies and architectures • The report includes aspects relevant to both Smart Grid and IoT. • Document shared in 802.24 Private Area • IEC_SEG8_Deliverable2_draft_181118_ext_clean.pdf • Updated version uploaded to private area with annotations • Key chapters relevant to input from 802.24 • IoT Technologies • Single-pair Ethernet (SPE) • Deterministic Networking • Low-Power Wide-Area Networks (LPWAN) • V2V, V2I, V2P and V2N communication technologies • Final Opportunity to review and comment as SEG8 is finishing in next few months Tim Godfrey, EPRI

Tim Godfrey, EPRI

  15. Tuesday 802.24TAG Tim Godfrey, EPRI

  16. “Network Integration” action item • Action assigned from 802 EC leadership conference in July. • Discussion on role and positioning of IEEE 802 in standards, especially with respect to 3GPP and the publicity on “5G” • What is meant by Network Integration? • Does the IEEE 802 architecture provide a unique value to vertical market? • Is IEEE 802 more suited to deployment in the communication infrastructure of private enterprise, industry, and the individual user? (Compared to 3GPP, which is more oriented towards service providers?) • The IEEE 802 architecture enables networks that are like Ethernet: Well understood, mature, predictable. A “cleaner” integration of disparate technologies under the common architecture and addressing. • Can we develop a clearer definition and description of this distinction and the value for the user / implementer? • Can this be developed into a white paper? Tim Godfrey, EPRI

  17. Review of 802.1CF in this context • November Presentation • Max Riegel “Thoughts on IEEE 802 network integration with respect to P802.1CF” 24-18-0026r0 • Discussion • Based on many discussions of the place of 802.11 in 5G. • 5G SC • Conclusions – AANI integrating 802.11 into 5G domain. Nothing corresponding in 3GPP • Industry connections – NENDICA • Flexible Factory IoT, Data Center Bridging • What’s missing – a picture of 802 as a peer to 5G • 5G promises they will do “everything” • But, they don’t do anything wired • 5G requires an extensive PLMN to support it. • It is designed to help the cellular operator grow their market • Verticals might not want an operator in the middle of their network • Value proposition: 802 networks are customer-owned • Example – Santa Clara Emergency services issues Tim Godfrey, EPRI

  18. Key Points from Discussion • IEEE 802 is a transport network • IEEE 802 is Layer 2 • 3GPP RAN is layer 3 only, Layer 2 is not available • Direct support of IPv4 and IPv6 or pure layer 2 protocols • Trade-off between flexibility (L2) and scalability (L3) • Routing provides path to higher scale • Smaller scale provide more flexibility • Smaller scale provides opportunity for real-time • IEEE 802 can route via L3 when needed. 3GPP cannot offer L2 • IEEE 802 can also offer L2 routing when appropriate (e.g. 802.15.10) • Not an alternative to L3 routing, but there to address a different problem Tim Godfrey, EPRI

  19. Key Points, contd • 802 does not provide as many means control a specific end device and it’s traffic on a path. • There are some management facilities in some standards • 3GPP networks provide more tools for subscriber management • 802 provides local networks that may be (but don’t have to be) connected into an Internet. • Operator networks are focused on services for single devices, while 802 networks support and include multiple devices (networks of networks) – devices can communicate with each other as well as with other networks Tim Godfrey, EPRI

  20. Non-802 wireless IoT networks • Commercial, proprietary IoT services • They don’t have an ethernet like L2. The system does not have the concept of a LAN. It is terminal to central “gateway” only. Star topology only. • Similar to LTE UE to UE traffic that must route through core. (DTD Proximity services have addressed that to some extent) • 5G URLLC, and MMTC. • IEEE 802 has already developed TSN in wired, and now being developed for wireless. • Latency is impossible to guarantee in unlicensed, shared spectrum. However it can be highly optimized by the MAC layer. • IEEE 802 has a history and internal coordination of coexistence between different standards operating in unlicensed spectrum. 3GPP is oriented towards exclusively licensed spectrum, “sharing” is a foreign concept. • 3GPP has a common strategy for the three use cases. IEEE 802 has a common architecture, but not a common business strategy. • License exempt can provide higher economic value per MHz of spectrum. • See WFA economic value. Cisco Visual Networking Index. Wi-Fi carries more data than all cellular spectrum • Wi-Fi created the expectation of broadband wireless that led to the development of LTE • What would it look like to combine multiple IEEE 802 standards into a single offering? • Some vendors already do that – integrating 802 technologies into systems. • The “Package” offered by the “5G” ecosystem is clearly articulated. • What is the comparable offering from IEEE 802? Tim Godfrey, EPRI

  21. Key Points, contd. • IEEE needs to think about how to create that package without a “subscription model” • IEEE 802 is often free • IEEE 802 is deployed in vertical markets, where the network is owned and operated by the user of the services. • Are there other models for IEEE 802 other than subscription that can provide ancillary economic value? • Is management of shared spectrum a candidate? • IEEE 802 and unlicensed spectrum enables faster innovation • Many of the breakthrough innovations were not as planned • The story of why IEEE 802 complements everything else, and everything else (alone) is not sufficient. • IoT is built around many specialized niches. The challenge is meeting the diverse requirements. IEEE 802 provides multiple standards to address multiple IoT applications. Tim Godfrey, EPRI

  22. Next Steps • Do we pursue a white paper in this area? • Yes, there is a good reason, and a starting point • Volunteers to assemble notes into a draft white paper • Next meeting of IoT - May in Atlanta? or Vienna? Tim Godfrey, EPRI
