3. Challenge Multiple Input Multiple Output (MIMO)
Arbitrary: 제멋대로
In Wi-Fi technology, MIMO is used since n, LTE and Wi-MAX as well.
How can we use full duplex technic in MIMO?

4. Wireless Full Duplexing
Full-Duplex Design
C(3*10^8)/F(3G= 3*10^9) = 10cm

Their Design
Full-Duplex Design with MIMO
We can get a real-time in-band feedback and control channel in the reverse direction with a high speed forward direction data channel.

7. Application
