During the keynote at 5G World 2019, Youngsoo Seo, SVP, Head of Regional Network O&M Headquarter, KT explained that one of the main differentiation for KT 5G network is the reduced latency. While a normal 5G network would take 18 ms, KT 5G network takes only 10ms.
Latency is a big area of focus for KT. Their announcement on 5G commercial network launch had 8 mentions of latency. Mainly:
KT’s ‘5G First’ Network Strategy Focuses on Latency and Speed
KT unveiled its “5G First” strategy to focus on providing the best network, with an emphasis on latency. By favoring the 5G network, this new strategy makes the best of 5G’s ultra-low latency and helps conserve smartphone batteries about 25 percent.
The press release also mentioned:
To better support 5G’s ultra-low latency, KT also operates mobile edge computing (MEC) telecom centers in eight major cities, including one on Jeju Island, the country’s southernmost territory. Using the largest number of MEC centers, the company can process data from handsets closest by to enable more reliable and seamless transmission.
Low latency is vital for 5G users to enjoy immersive media such as cloud-based streaming games and AR/VR as well as other key services such as autonomous driving.
One of their 5G adverts focuses on AR & VR apps that definitely requires low latency
Netmainas has a good summary of the South Korean giants SK Telecom and KT here. In a recent article, they outlined the KT's 5G NSA Network architecture as shown above. Their website provides much more details.
With the Standalone 5G network, they will be able to reduce this latency much further once the UPF can be optimally located to reduce latencies where really needed.
