The centres will allow the telco to process data from handsets close by, which is important for 5G that has ultra-low latency.
Previously, processing wireless data for 4G LTE involved having data traffic nationwide be sent to the central telecom centre in Seoul which often caused delays.
Those living in Jeju Island, the island region at the south of South Korea, will see internet access speeds be boosted by 44 percent compared to LTE as there will be an MEC centre there, KT said.
The telco said it also applied its 5G core equipment in the control and user plane separation (CUPS) architecture, as well as in the network virtualisation technology of the MEC centres.
CUPS separates devices that process signals from those that process traffic so that each can be expanded independently from each other. This helps centres expand their traffic processing capacity independently, which is very important for 5G mobility, KT said.
KT added that it plans to use MEC centres actively for the deployment of its own autonomous cars, smart factory, augmented reality, and virtual reality services.
Samsung's mmWave radio frequency integrated circuits (RFICs) and digital/analog front end (DAFE) ASICs supports 28GHz and 39GHz bands, which can reduce 5G base station size, weight, and power consumption by 25 percent.
LG's 6.26-inch Q60 and K50, along with the 5.7-inch K40 smartphones will have premium camera, AI, and sound features, LG Electronics has said, leaving everything out in the open ahead of the G8 ThinQ launch at Mobile World Congress.
