What is 4G?
“4G to me is not about the next radio link; it is much more about how you deal with a set of heterogeneous networks and get bits to and from the device in the most cost-effective way”
Paul Jacobs, Chief Executive Officer, Qualcomm

Highlighted Use Cases Enabled by the Connected Home
• User selects an internet radio station and pushes it to the Roku to listen while making dinner in the kitchen. Does this from a mobile phone.
• Vacation slideshow is pushed to a digital picture frame located in the living room. Does this from a mobile phone.
• High Def video is sent to playback on the large screen TV in the den for the kids. This is done from the user’s PC.

What are the hurdles in front of 4G?
• Technical– Interoperability (mobile and CE)– Scalability
• Multi-device• QoS
– Power consumption– New industrial designs and user interface (next
iPhone)
• Business– ROI for 3G– Penetration/Saturation of multimedia vs. other
applications
