7. Possible 5G Techniques

8. 4G OFDMA 、 SDR 、 MIMO Fast moving transmission capacity = 100MBps Stationary state capacity = 1GBps Cellular mobile communication systems

9. 5G Upgrade 100-1000 times than 4G Connect billons of devices in same time D2D mmWave Massive MIMO Smarter devices M2M

10. 1.Device-centric architectures Need additional spectrum Centralized baseband CoMP

11. 2. Millimeter wave (mmWave) To repurpose or refarm spectrum To share spectrum utilizing 28-30, 60, 71-76, 81-86, 92-95 GHz 3. Massive MIMO Having many more base station antennas

12. 4. Smarter devices D2D Local caching Advanced interference rejection

13. 5. Native support for machine-to- machine A massive number of connected devices Very high link reliability Low latency and real-time operation

14. Application of 5G

15. Why We Need 5G ? ●IoT ●4K Video Stream ●Alternative Solution of Last Mile

16. ●Internet of Internets ●Every things on the Internet IoT (Internet of Things)

17. Devices Growing Rapidly

18. IoT (Internet of Things) IoT helps people collect Data, and then Improve Human’s live.

19. 4K Video Stream ●Every thing on the Cloud --> HD Video Stream o 4K Streaming : 14 Mbps o 8K Streaming : 18 Mbps

20. Alternative Solution of Last Mile ●The Physical Last Mile is not Necessary. ●The Operators- builded Wireless network is Everywhere
