Possible 5G Techniques
4G
OFDMA、SDR、MIMO
Fast moving transmission capacity =
100MBps
Stationary state capacity = 1GBps
Cellular mobile communication systems
5G
Upgrade 100-1000 times than 4G
Connect billons of devices in same time
D2D
mmWave
Massive MIMO
Smarter devices
M2M
1.Device-centric architectures
Need additional spectrum
Centralized baseband
CoMP
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
4. Smarter devices
D2D
Local caching
Advanced interference rejection
5. Native support for machine-tomachine
A massive number of connected devices
Very high link reliability
Low latency and real-time operation

Why We Need 5G ?
● IoT
● 4K Video Stream
● Alternative Solution of Last Mile
IoT (Internet of Things)
● Internet of Internets
● Every things on the
