CDSUMMIT 2015: Ruckus Wireless' David Wright

  1. 1. Dave Wright Advanced Technologies Update on Unlicensed Spectrum and Wi-Fi
  2. 2. 2 CommsDay Summit 2015 Looks can be Deceiving 2
  3. 3. 3 CommsDay Summit 2015 Unleashed Access “Wi-Fi has cemented its position as the dominant wireless access technology, with cellular playing a vital yet supporting role.” Mike Roberts, Practice Leader OVUM
  4. 4. 4 CommsDay Summit 2015 13.8 4219.2 25 Leading in Service Provider Wi-Fi Ruckus Vendor Market Share Cisco HP Others 24.4 34.7 11.7 29.2 Ruckus Cisco Ericsson Others 4 10.7 Unit ShipmentsMFG Revenue
  5. 5. 5 CommsDay Summit 2015 Some of our Operator Deployments MNO Cable/Fiber Operator Large MSP/WISP
  6. 6. 6 CommsDay Summit 2015 Simply Better Wireless THEM US 1.Stronger Wi-Fi signals at longer ranges 2.Adapts automatically to environmental changes 3.More concurrent users per access point 4.Stable connections at higher data rates 5.Unmatched scalability 6
  7. 7. 7 CommsDay Summit 2015 A Perfect Storm − Carrier Wi-Fi 7
  8. 8. 8 CommsDay Summit 2015 The Value of Unlicensed Spectrum o Wi-Fi has seen unprecedented success o Simple integration – over 10 Billion Wi-Fi enabled devices o Widespread adoption across virtually every market segment o Massive scale with ~$140B/year economic impact in US o LTE is jumping into 5 GHz spectrum o LTE-U, LTE-LAA, LWA o Fair sharing is the future 8
  9. 9. 9 CommsDay Summit 2015 The Future of Spectrum o Spectrum Sharing highly favored by regulatory agencies o Sharing regimes can provide: o Access Flexibility: e.g. 3.5 GHz Incumbent, priority, and general authorized o Frequency Flexibility: e.g. Priority access to 10 MHz paired in various areas o Time Flexibility: e.g. Long-term, short-term, or on-demand o Sharing regimes require careful coordination o 3.5 GHz is a high priority for shared access, dense deployments
  10. 10. 10 CommsDay Summit 2015 LTE in Unlicensed Spectrum o Fair Access is critical to protecting Wi-Fi users and services o Listen before talk (LBT) is not supported in pre-standard LTE-U proposals o CSAT is an optional best effort technique o LBT must be mandatory to ensure fair sharing for LTE-LAA o Wi-Fi community will lobby for LBT as part of 3GPP standard o LWA utilizes 802.11 CSMA/CA for medium access 10
