4. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 4 Home Networking Orange provides services to more than 170M clients over five continents With activities in Home Networks… –European leader for high speed internet (ADSL) with ~ 12M subscribers –6.1M Livebox units(WiFi homegateway) –N°1 in Europe for TV over ADSL with more than 1.2 million subscribers … always looking for new technologies for Home Networking to provide more services, with better QoS

5. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 5 Objectives for home networking Technologies satifying our use cases: –With guaranteed QoS no service interruption –With guaranteed coverage providing high data rates wherever required –While using sustainable technology Avoiding over-consumption of resources (power, spectrum..) optimizing available resources to adjust to varying traffic conditions and service requirements (data rates, range,…)

7. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 7 Presentation of Use Case Family: Peter and Jane, their son John (11), their daughter Mary (14) Wireless home network with their Home Gateway John Mary Peter and Jane Kitchen Living Peters office

8. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 8 Living Peters office Family wake up Scenario –7:00am // Parents wake up with music. Soon after they wake up the children –Parents go downstairs. Music follows them from their bedroom to the kitchen –Children decide to watch a movie on the bedroom TV –Time for breakfast: children go to the kitchen. Their movie follows them to be transmitted on the kitchen TV –8:30am // Time to go to school for children ZZZ … Music

9. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 9 Family wake up What's happening here (11ac/ad)? –Long range medium data rate applications:  60GHz 11ad is insufficient: combination with 11n or 11ac –When applications are in short range:  over-consumption of bands if both 11ac and 11 ad are active  by using 11ad, decrease chance of OBSS Conclusion This can be implemented with dual radios (11ac and 11ad) without a specific "fast session transfer"

10. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 10 Back Home Scenario –5:00pm // Jane is watching a cooking show downstairs on a web-tablet. Peter is downloading a 3D movie for the evening and joins her in the kitchen. –Children come back from school with a friend of theirs. –Mary, in the patio, starts a video phone call with a friend of her. She decides to go to her room where she transfers the communication from her iPhone to her big screen. –John and his friend want to play a 3D game in the living (uncompressed) –Mary goes upstairs to finish view cooking show because 3D game is too loud –Mary hears John going to room and decides to returns to kitchen to finish watching show and start cooking dinner with Peter

11. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 11 Back Home General constraints –Uncompressed video + multiple high throughput applications Solutions to avoid saturation QoS and no service interruptions in case of mobility What happens with 11ac/ad? –Uncompressed video: Need 11ad –Long range high throughput: Need 11ac –Saturation/overload –Coverage limit of 11ad Dynamic transfer to and from 11ac on the same device

12. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 12 Solutions?

13. doc.: IEEE 802.11-09/0835r0 Submission July 2009 John Benko, Orange LabsSlide 13 Conclusions 11ac and 11ad, independently, do not enable the use cases with required QoS in future home environment Both are required –11ad: For high throughput –11ac: For long range We believe that fast session transfer between 11ac   11ad is necessary –Beneficial for: –Coverage –Saturation of bands –Interference reduction/OBSS Questions that still need to be addressed: –How fast is needed, for "fast session transfer"? Is a mechanism built without modifying 5GHz system (11a,n and ac) sufficient? Or do we need to modify 5GHz systems (11ac)?
