802.11ac Customer Use Cases

• Higher bandwidth use in Hotspots provides a differentiation from

the competition

• Generate more revenue by charging for more bandwidth

• Customer get a much better user experience through

hotspot access to high BW Apps such as Netflix or Hulu

Plus

• Continued shift to 5 GHz will offload the already crowded 2.4 GHz

Higher Education K-12 Education

• Hospitals can transfer large MRI Images or provide live viewing

from remote locations in the hospital.

• Deploy in Density high-density conference areas and meeting

rooms to address issues resulting from more devices

• Faster File transfer means less contention on the network for

other applications

• Collaborative Classrooms with HD Video

• Example: Multi-screen HD video is streamed live to

802.11ac and 802.11n enabled devices in classrooms
