Session Introduction

• The “Internet of Things”, “Smart Objects”, Smart Utility Networks,

and M2M are common buzz words in today’s technical vocabulary.

This presentation will give context to those terms in relation to

developing IETF and IEEE standards.

• Freescale has made partnerships to come up with a joint solution to

address these networks with IPv6 standards based networking

software and Freescale Kinetis Processors and Sub-GHz radios.
