Operator’s perspective on 5G

The three core values of 5G are customer experience enhancement, new business opportunity, and efficient/intelligent operation

from massive IoT,mission-critical IoT

3) Innovative Services

2) All-IT Infrastructure

1) S/W-defined RAN

for virtual experience, massive IoT, & critical IoT

for value creating network,monetization

Openstack/SDN/NFV based S/W Defined Access Network with Open Fronthaul Interface

5G architecture

SK Telecom’s 5G architecture consists of 3 layers:

1) S/W-defined RAN (SDRAN), 2) All-IT infrastructure, and 3) Innovative services
