2 What you expect here Tizen 1.0 Tizen 2.0 Tizen 3.0 Tizen Next Platform Smart Devices Connect Everything Optimized IoT OS

3 IoT and Connectivity 3 3

4 Internet of Things? ITU-T Y.4000/Y.2060 reads A global infrastructure for the information society, Enabling advanced services By interconnecting things based on existing and evolving interoperable information and communication technologies 4 4

5 Internet of Things! It provides convenience By talking each other Home 5 It s time to clean the house~! 5

6 Why connected? Get and Set See what status things are, and tell what they do Collaboration Provide more value than each value Beyond own resource Handle tasks, borrowing others capabilities 6 6 Rob Chandhok, A fast track to the Internet of Everything, Oct. 18, 2013

7 Connectivity Diversity Various home High-end TV vs. toaster Whatever high-end devices want Wi-Fi too heavy for toaster Streaming video vs. notification Heavy traffic Light traffic AC vs. Battery-powered Almost unlimited power Life-limited battery 7 No single connectivity makes everything(!) happy 7
