  1. 1. Future Wireless Broadband AccessThinking Beyond LTEMay 24, 2012Alan CarltonSenior Director, Corporate Planning © 2012 InterDigital, Inc. All rights reserved.
  2. 2. Wireless Broadband: Where we stand today  Cisco projects an 18-fold increase in mobile data traffic over the next five years. Video will be by far (70.5%) the dominant traffic profile driving this demand explosion  Wireless Service Providers are moving to tiered service levels & traffic shaping to manage spectrum resources in response to this growing demand for data connectivity  Urbanization, shift of traffic indoors & need for better use of spectrum is driving small cell technology, a network-of-networks & a blurring of the once cellular-WiFi divide  Digital immigrants are giving way to the digital natives who are reinventing the media experience that will challenge even the most aggressive infrastructure investment  Today’s wireless technology & spectrum roadmaps will struggle to keep ahead of demands & shifting user behavior. New thinking on spectrum & architectures required2 © 2012 InterDigital, Inc. All rights reserved.
  3. 3. The Bandwidth Crunch Challenge More spectrum debate continues but we believe it will only be part of the solution Average Population Devices/ Busy Required Area Speeds* Density Person Hour Capacity** 2012 0.3Mbps x 4984/km2 x 1.20 x 15% 0.26Gbp/s/km2 2016 2.9Mbps x 5191/km2 x 1.40 x 20% 4.2Gbp/s/km2 2020 30Mbps x 5477/km2 x 1.70 x 25% 69.8Gbp/s/km2 Assuming state of the art LTE-A** today  In 2016 we may need 317MHz of spectrum London  In 2020 we may need more than 5GHz! More spectrum and new thinking is required to meet this challenge* Cisco Visual Networking Index 2012 **Assumes 2.6b/s/Hz/cell with 500m ISD 3 © 2012 InterDigital, Inc. All rights reserved.
  4. 4. InterDigital Communications Research: What We Do InterDigital develops fundamental wireless technologies that are at the heart of mobile devices, networks, & services worldwide.
