The future of Internet of Things
2
Future IOT requires new network capabilities to
support massive number of devices, and efficient
SW/HW platforms for both devices and networks
Future IOT requires close partnership among many
industries and ecosystems to offer integrated
compute and communication capabilities

IOT requires end-to-end design considerations, from
sensors to the cloud
Standards collaboration and regulatory compliance
are essential

5G
• Future applications require intensified compute and
communication but often smaller device form factor
• 5G high data rate + low latency radio links enable mobile
device + access virtualization across the air interfaces
• 5G services are immersive. Sensing, intelligence and contents
require edge cloud and device + access virtualization
• Breaking computing barrier through communication may
transform consumers’ relationship with network
5G device+access virtualization for scalability, versatility, energy efficiency
