6. Goals for AR/VR collaboration in 802.24
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
will liaise to other WGs if they develop amendments to their standards to support RTC.
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
will provide a venue for collaboration (joint meetings) at Plenary
Tim Godfrey, EPRI

7. 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

11. “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

12. Review of 802.1CF in this context
November Presentation
Max Riegel “Thoughts on IEEE 802 network integration with respect to P802.1CF” r0
Discussion
Based on many discussions of the place of in 5G.
5G SC
Conclusions – AANI integrating 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

13. 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 )
Not an alternative to L3 routing, but there to address a different problem
Tim Godfrey, EPRI

14. 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

15. 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

16. 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

17. 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
Discuss at next meeting of TAG - May in Atlanta, and also in July in Vienna
Tim Godfrey, EPRI

18. Wednesday TAG
Tim Godfrey, EPRI

19. ITU and Radio Regulatory Items
Update from – Jay Holcomb
900 MHz licensed spectrum NPRM
Will be discussed at Open Meeting of FCC
Call 900 MHz Broadband, but is not related to ISM band.
and MHz. Propose to transition part of band from channelized LMR to 3x3 MHz. Move LMR into remaining portion of band.
Up to 400W/MHz PSD ESD on towers 304m. (similar to narrowband paging at 1KW)
Is there a possible interference concern with ISM systems in MHz?
OFCOM – MHz consultation
High power devices could interfere with lower end of 2.4 GHz ISM band
This is planned as licensed spectrum
will consider a late filing
Tim Godfrey, EPRI

20. Liaison with ATIS TOPS Council IoT Categorization Focus Group
ATIS: Alliance for Telecommunications Industry Solutions
Review and comment on IoT Characteristics Matrix provided by ATIS
Review completed and matrix with comments posted as r4
Will be forwarded back to ATIS committee
Tim Godfrey, EPRI

21. “Low latency” White Paper
Achieving low latency with IEEE 802 standards
Including wired and wireless communications
An alternative (or complement) to 5G URLLC
A set of vertical applications enabled by low latency
The challenges of reliable low latency in unlicensed spectrum.
Adapting TSN’s “FRER” feature
Adapting 802 wireless to licensed spectrum?
Operating over multiple bands or channels?
Special cases for high data rates for immersive video
Oliver Holland is leading white paper development
Outline draft discussed, edited, and updated as r1
Tim Godfrey, EPRI

22. 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
project schedule:
A draft ready by April
WG Ballot Sept 2019
