WLAN & Bluetooth ?Which Network?GPRS, UMTS, WLAN, Bluetooth, Ethernet ? Which Device? Phone, PDA, Tablet, Laptop, Desktop, Xbox ?How to maintain Connectivity? ?How to get one unified experience?

  4. The Achievements • Complete end-to-end mobility management solution without changing the network infrastructure • Received MIT Technology Review world’s top young innovator award (TR100) in 2004 • Received the Best Asia Pacific Young Researcher Award elected by IEEE Communication Society in 2005 • Core technologies transferred to Microsoft product • International patents for related technologies

  5. Spectrum, Spectrum, Everywhere, but . . . Dynamic Spectrum Access and Spectrum Management is the way to GO!

  6. Real Road Spectrum Road Dynamic Spectrum Management PRI SEC Dynamic Spectrum Access and Management • Spectrum users • Primary (PRI) user (with license) uses spectrum when desired • Secondary (SEC) user opportunistically uses remaining spectrum • Goals: • maximize spectrum utilization while minimize interference • Road analogue (spectrum bands  lanes, spectrum users  vehicles)

  7. CRN and DSA: A Multidimensional Activity Spectrum /channel usage understanding and modeling

  8. The Achievements • Work on multiple aspects related dynamic spectrum management, including spectrum usage modeling, policy/marketing, core technologies, testbed/platform, etc. • Received the Overseas Young Investigator Award from the National Natural Science Foundation of China (NSFC) in 2007 • Received the Chinese Young Scientists Award by China Association for Science and Technology in 2011 • Received the Best Paper Awards from various international conferences, including Globecom, ICC, ICDCS, Qshine, etc. • Core technologies transferred to Huawei Corp. and Alcatel-Lucent Corp. • International patents for related technologies
