  • 5. • Mobile Internet Demand is non-uniform • Peaks of demand in certain hotspots can exceed cell capacity • Baseball stadium deployment – 5500 devices generating 52 Mbps traffic • Some estimates predict that 12-sector cell in Olympic park will only be able to support 30% of mobile Internet traffic demand • 12,000 devices attached to WiFi during Superbowl XLV • How to scale metro – continuing splitting macro cells or do something different?© 2010 Cisco and/or its affiliates.

  • 7. • Future Networks supporting the Mobile Internet will need to seamlessly integrate a lot more smaller cells • Shifting from 104 cells to 106 cells will require a change of mindset and management tools • Key decisions that need to be considered: • Whether to use unlicensed, licensed technology or both? • If using unlicensed, what does the “SP WiFi” architecture look like?© 2010 Cisco and/or its affiliates.
