Submission Slide 2 Monisha Ghosh (InterDigital) September 2014 doc.: IEEE 802.11-14/1249r1 Recap of Backhaul Usage Model • Small cells are becoming increasingly important for cellular and Wi-Fi [1]. • Requirements: • • • • ~ 2 Gbps peak per small-cell data rate 100 m – 150 m cell size Latency: ~ 5 ms, one way, end-to-end. Support for bursty traffic • mmW backhaul enabled by 802.11ad/NG60: • Leverage availability of low-cost chipsets, driven by volume (ABI Research: 1.5 billion chipsets by 2018) Submission Slide 3 Monisha Ghosh (InterDigital) September 2014 doc.: IEEE 802.11-14/1249r1 What does backhaul need from NG 60? • Multi-hop capability. • Existing 802.11ad specification may not be sufficient for extended range applications. • Enhanced QoS guarantees: • Beyond current 802.11ad specification. • Higher data rate • Will be addressed by planned high-data rate enhancements (MIMO, channel bonding, etc.). MU-MIMO may be beneficial as well. • Enhanced discovery methods for longer range • Discovery range = Communication range. Submission Slide 4 Monisha Ghosh (InterDigital) September 2014 doc.: IEEE 802.11-14/1249r1 Use cases enabled • Solutions that meet the backhaul requirements will also provide benefits to other use cases of interest: • High-data-rate indoor applications [2], such as video streaming, would benefit from extended range. • Deployment of infrastructure NG60 APs would benefit from the possibility of self-backhaul, leading to lower-cost. Submission Slide 5 Monisha Ghosh (InterDigital) September 2014 doc.: IEEE 802.11-14/1249r1 Conclusions • Support for backhaul in NG60 may require MAC only or PHY/MAC enhancements to current 802.11ad. • Support for backhaul in NG60 will enable new deployment and use scenarios that may not be fully served by 802.11ad. • Support for backhaul is complementary to high-rate enhancements such as MIMO, higher-order constellation, channel bonding etc. Submission Slide 6 Monisha Ghosh (InterDigital) September 2014 doc.: IEEE 802.11-14/1249r1 References [1] 11-14/0579r1, A Backhaul Use Case For NG 11ad, Joseph Levy et al, May 2014.
