5G connected autonomous car trial (2018.2, SKT))

Built 5G pilot networks with Samsung and demonstrated world 1st 5G connected autonomous car with Korean Transportation Safety Authority

- Set up a self-driving car pilot city in Hwaseong, covering 363,000m2 with 28GHz 5G trial N/W - HD map provides detailed traffic info. including reports of accidents on real-time

Network functions will increasingly be running in cloud environment for efficiency.The cloud environment will be programmed and orchestrated by intelligent orchestrator.
