Still 99% of THINGS are not connected
• Gartner: around 4.9 billion connected ”things” in use by the end of 2015,
up 30% from 2014.
• IDC: worldwide IoT market worth $656 billion in 2014.

5G Use cases
Enhanced Mobile Broadband 10/20 Gbps, 1000x more capacity/area
Massive Machine Type Communications 106 devices/km2
Ultra-reliable and Low Latency Communications >99.999 and <1ms
Fundamental change in research approach
Start from end user QoE
Unlike 2G….4G , designed for end device
Data to Information trandormation
Start from density cell network technologies
Scalable to macro cells-----------unlike previous generations
New waveform scalable from IoT to Broadband, spectrum aggregation ….
Capacity & Energy efficiencies, Latency , Reliability
Speed is not the differentiator between 5G and previous generations
Spectrum and system agnostic
Uniformity operation across licenced and licenced-exempt bands
Broadcast, Cellular, WiFi technologies all support: Data, Video, Audio
