  20. NG60 SG status review • Next Generation 60GHz (NG60) Study Group • Duration: September 2014 – March 2015 • Interest continues to be high in the Study Group • An average of 3 meeting slots assigned every F2F meeting • Average attendance per time slot is in the neighborhood of 70 • PAR and CSD • Approved by IEEE 802 EC, IEEE-SA NesCom and IEEE Standards Board in March and April 2015 • PAR: 14/1151r08 • CSD: 14/1152r08 Edward Au (Marvell Semiconductor)

  21. PAR NG60 SG status review • Supporting a maximum throughput of at least 20 Gbps • Throughput is measured at the MAC data service access point • Expected to provide improvements of over 3 times • Maintaining or improving the power efficiency per station • Indoor and outdoor operations in license-exempt bands above 45 GHz • Enabling backward compatibility and coexistence with legacy directional multi-gigabit devices (defined by IEEE 802.11ad-2012 amendment) operating in the same band Edward Au (Marvell Semiconductor)

  22. CSD: Technical Feasibility NG60 SG status review • The principle of scaling the IEEE 802.11 PHY and MACs to higher throughput is well established by previous amendments, such as IEEE 802.11ac-2014 and IEEE 802.11ad-2012 • NG60 builds on the broad knowledge base and system design experience of IEEE 802.11ad devices. • For example, NG60 will consider MIMO and channel bonding that not only significantly improve throughput, but also allow reuse of technologies and testing being used in the previous amendments. Edward Au (Marvell Semiconductor)

  23. CSD: Distinct Identify & CompatibilityNG60 SG status review • NG60 is different from other IEEE 802 wireless standards/projects in that it is specific for 802.11 WLANs and aims to provide data rates in excess of 20 gigabits per second for point-to-point and point-to-multipoint indoor and outdoor usages for license-exempt bands above 45 GHz. • NG60 will ensure coexistence and backwards compatibility with IEEE 802.11ad, thus creating a solution compatible with existing IEEE 802.11 deployments. • Coexistence with other systems for license-exempt bands above 45 GHz will be evaluated and documented in Coexistence Assurance document.

  33. Usage Model • Consolidated document: 15/0328r4 • Tentative Purposes: • Consolidate the usage models presented by different participants into a single document • Prioritize the usage models so as to have a clear understanding of key categories • Questions: • Once the usage model document is finalized, does the Task Group prefer to establish a liaison with Wi-Fi Alliance requesting feedback on usage scenarios? • If so, what is the expected timeline? Edward Au (Marvell Semiconductor)

  34. Channel Modeling Document • Consolidated document: No • Tentative Purposes: • Select a few representative usage models for modeling channels appropriate for NG60 • Describe channel models based on the results of experimental measurements Edward Au (Marvell Semiconductor)

  35. Functional Requirements Document • Consolidated document: No • Tentative Purpose: • List of functional and system performance requirements for the task group Edward Au (Marvell Semiconductor)

  36. Simulation Scenario & Evaluation Methodology Document • Consolidated document: No • Tentative Purposes: • Identify a minimum set of representative simulation scenarios from usage models • Identify performance comparison metrics to evaluate gains of different technical proposals Edward Au (Marvell Semiconductor)

  37. Straw Poll #1 • Do you agree with the proposal to develop documentscovering the following components? • Usage model • Channel model • Functional requirements • Simulation scenario and evaluation methodology • Yes: 51 • No: 0 • Abstain: 1 Edward Au (Marvell Semiconductor)

  38. Straw Poll #2 • Do you agree to send a liaison to the Wi-Fi Alliance in the May session requesting feedback on usage scenarios? • Yes: 51 • No: 0 • Abstain: 0 Edward Au (Marvell Semiconductor)

  39. Selection Procedure • Two approaches have been in use in the IEEE 802.11 WG to develop various amendments • Call for proposals (CFP): • Proposals may be complete or partial proposals. • Proposals are submitted by a deadline, which is determined by the TG. • Requires the harmonization between various proposals in case multiple proposals are received. • Specification framework document (SFD): • SFD is a high level requirement document describing features related to MAC, PHY, MIMO, etc. Allows participants who may only be interested in specific features and not on others to submit their proposals. • A gradual approach for developing main features of the amendment as the work in the TG progresses. • Consensus is built gradually as it relates to a specific feature. Edward Au (Marvell Semiconductor)

  40. The CFP Approach • CFP was the approach followed in TGn. Three full proposals and many partial proposals were submitted. • None of the full proposals achieved the required 75% approval ratio. • Much time was spent to harmonize complete proposals and come up with a single proposal. • CFP was also used for TGad. One complete proposal was submitted and it absorbed a number of partial proposals. • Once the complete proposal was approved, the development of IEEE 802.11ad amendment progressed relatively fast. Edward Au (Marvell Semiconductor)

  42. The SFD Approach • SFD was used in the development of 802.11ac amendment • MAC, PHY, MU, and Coexistence features were developed gradually and in parallel. • Proposed specification, which includes all the items in SFD, was introduced and approved by the TG • TGah and TGai have also used the SFD approach. • TGax is also now busy in developing its SFD Edward Au (Marvell Semiconductor)
