The trials in Pyeongchang, Jeongseun and Gangneung are using Nokia's ViTrust public safety LTE network – which includes LTE radio access, cloud packet core and other commercially available technologies – interworking in the multi-vendor environment comprising SKT's existing evolved packet core system.
Nokia is also deploying its mission-critical push-to-talk technology to allow one-to-many communications using enhanced multimedia broadcast multicast services (eMBMS) technology to transmit HD video and other data.
"We are pleased to be leading the way with this important Public Safety LTE trial. Working with Nokia we have been able to ensure fast deployment of technologies and enable the delivery of services that will transform the way public safety workers operate,” SK Telecom SVP of infrastructure Sang-soo Shim said.
