Guidelines for IEEE-SA Meetings All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws. Don’t discuss the interpretation, validity, or essentiality of patents/patent claims. 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.

ITU and Radio Regulatory Items Update from 802.18 – Jay Holcomb 900 MHz licensed spectrum NPRM (Broadband) Will be discussed at Open Meeting of FCC Interference with ISM? OFCOM – 2390-2400 MHz consultation Tim Godfrey, EPRI

Collaboration with 802.21 AR/VR Vertical Applications 'Network Enablers for Seamless HMD-based VR (Virtual Reality)’ Subir Das Tim Godfrey, EPRI

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

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

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

“Network Integration” action item Define the value and differentiation of the IEEE 802 architecture in the context of vertical markets How is IEEE 802 better suited to deployment in the communication infrastructure of private enterprise, industry, and the individual user?  Compared to network architectures 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. Tim Godfrey, EPRI

Review of 802.1CF in this context Introductory 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

Points For Whitepaper Outline 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

Points For Whitepaper Outline 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

Points For Whitepaper Outline: Re: 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

Points For Whitepaper Outline 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
