SK Telecom along with Korea Transportation Safety Authority (KOTSA) has successfully deployed 5G infrastructure in K-City, the country’s pilot city for self-driving. K-City, located in Hwaseong, southwest of Seoul, has a total area of around 363,000㎡. 

The operator has deployed 5G infrastructure, including test network with 20 Gbps download capacity, 5G communications control center that transfers data to a test vehicle in less than 0.001 second, and 3D HD map with high accuracy of less than 20cm.

K-City achieved an end-to-end system, meaning that both wireless and wired slots in the facility are connected in 5G network. To realize its 5G infrastructure, the latest 5G technologies -- 5G virtualization, beamforming and beam-tracking -- were adopted.

K-City has a variety of test driving lanes that resemble real world driving conditions such as a school zone and bus-only lane.
