KT tested 5G network slicing technology at a World Cup street-cheering site packed with large crowds.
KT said on the 28th that it carried out a 5G standalone-mode network slicing demonstration at a street-cheering event held around Gwanghwamun in Seoul on the 25th.
Network slicing is a technology that divides a single 5G network to be used like multiple virtual networks. For example, by separating communications used by general spectators from those for event operations, it can keep communications for specific purposes relatively stable even when crowds swell and traffic increases.
At this event, KT allocated dedicated network resources, separate from general users, to staff and to officials of the Seoul Metropolitan Government and Jongno District. Through this, it checked whether communications needed for event operations—such as push-to-talk contact, on-site situation sharing, and emergency response contact—were carried out stably even in a congested environment.
KT also compared the communication quality of devices with network slicing applied and ordinary devices. It said devices with slicing applied were relatively less affected by increases in surrounding traffic and maintained a stable communication channel.
KT said, "We confirmed the potential of 5G technology to provide different communication quality depending on the purpose, even in the same network environment," and added, "Based on slicing technology, we will offer new solutions in both B2B and B2C areas and expand the value of communications into various fields, including mega events, industrial sites, and public safety."
