  • 6. Our Topics For Today…  New technologies in .11ac – a quick review  How will 802.11ac impact enterprise wireless LANs?  Capacity, not just throughput  Evolution, not revolution  Increasing demands – users, devices, applications  What should the enterprise do now?  Wired infrastructure  Network management  Logistics  Initial and dense deployments  Conclusions and recommendations

  • 10. It’s Not Really About Throughput – It’s About Capacity Dense Deployments • Driven by BYOD • Time-bounded traffic (streaming video; voice) • Maximize channel efficiency • Maximize throughput/reliability by minimizing range RF Management Techniques • Beamforming • Beamsteering • Bandsteering • Auto channel/power selection • Spectral analysis Traffic prioritization/Airtime fairness Load balancing Source: Farpoint Group
  • 11. 1. Wired Infrastructure Consider Two Cat-6 Cables To Each AP Location Backhaul Capacity – Identifying Bottlenecks Consider 802.3at PoE Router Capacity Switch Capacity • Gig-E switches remain fine for the near term • Consider 10+ Gb uplinks Source: Farpoint Group

  • 18. Conclusions (for now…)  802.11ac will replace 802.11n – but not for many years  802.11n projects should continue to be evaluated (and deployed) based on current ROI  Go through the checklist items presented here – make sure your network is ready  Talk with your vendor about coexistence/migration plans  And remember: there’s more to successful WLAN deployments than radios!  Think architecture
