Outline
• In this presentation, we discuss the risk of a long timeline for 802.11ax, especially with regards to the early needs of densification
• We discuss some ways to speed up the improvement of user experience in dense environments, through the adjustment of 802.11ax timeline.

Risk of a too long timeline for 802.11ax
• If we take the example of 802.11ac to plan the timeline for 802.11ax– first products will reach market in 2018 and certified ones in 2019– there will probably be two waves of certifications as for 802.11ac
• This time-to-market is not so long for the long-term needs– building the Wi-Fi generation for the incoming 10 years.
• But we believe that 11ax brings improvements to Wi-Fi user experience that will be needed earlier than 2018-19
– Looking at operators needs for carrier grade Wi-Fi– Looking at the growing densification and demand in public places which impacts WiFi user
experience– Considering also alternative technologies on unlicensed bands– this is even more risky if we experience timeline drift as 802.11ah
This time-to-market is too long for these early needs

802.11ax should have multiple waves of certification
• 802.11 works with generations every 4-5 years– this model of generation has a very strong marketing value– it however creates long time between generations
• 802.11ac evolved on this point by creating different waves of certifications (releases) in WFA
• We believe it is important for 802.11ax to have also multiple waves of certifications in WFA (mix of generations and releases)
– with all features defined in 802.11ax that end-up in these certification programs: feature selection directly at 802.11 level
• But we need to see how to speed up the pace and reduce the time for the first wave of certification
– we would like to see propositions on this

Speed up the improvement of user experience in dense environments (1/2)
• Speed up the first wave of certification of 802.11ax
– WFA created 2 waves of certifications for 802.11ac, with 2 different timelines, but 802.11 worked on a single spec with a single timeline
– We consider that there will be multiple waves of certification for 802.11ax also
• with every wave having a set of PHY&MAC features taken from 802.11ax specification
– Why not taking this model to the next step by applying it, not only to WFA, but to IEEE 802.11 work as well

• Speed up the first wave of certification of 802.11ax
– Once the overall set of features has been agreed for 802.11ax, • the TG could decide at some point to split these features in 2 waves• and to validate the part of 802.11ax specification related to the
features of wave 1 before the one related to wave 2.– development towards draft 1.0 should focus on providing a mature spec for
the features targeted at 11ax wave 1
– This could reduce the time-to-market for the first wave of 802.11ax• some features don’t need a very long time to be standardized
Speed up the improvement of user experience in dense environments (2/2)

Conclusion
• 802.11ax has to set an ambitious timeline that it will respect– strict selection of the features that will reach market (as for 11ac)
• We also believe that 11ax brings improvements to Wi-Fi experience that will be needed earlier than 2018-19– we propose an approach to speed up that process
• some thinking is needed to see how to make it possible– and hope to see some discussion/propositions towards this goal
