SKT Trials Public-Safety LTE Technology in 3 South Korean Cities
Wednesday, April 11, 2018 | Comments

SK Telecom (SKT) and Nokia are conducting a trial of Long Term Evolution (LTE) public-safety technologies in South Korea. The trial in Pyeongchang, Jeongsun and Gangneung is being conducted with first responder teams to enhance communications and response time in emergency situations.

Nokia deployed its ViTrust public-safety solution, including LTE radio access, Cloud Packet Core and other commercially available technologies in the network trial. Working with local vendors to deliver services for the trial, Nokia is deploying its mission-critical push-to-talk (MCPTT) technology to allow one user to simultaneously connect with multiple first response personnel on a network.

Last year, the companies demonstrated a MCPTT solution at Nokia's research and development (R&D) center in Kraków, Poland.

Using enhanced multimedia broadcast multicast technology, high-definition (HD) video and other data can be transmitted efficiently to all devices even in high-traffic situations, to give all first responders a clear and complete view of an emergency and its needs.

The trial involves one of the world's first public-safety networks to interwork with SKT’s existing evolved packet core (EPC) system. This interworking will ensure network reliability, coverage and availability ensuring public-safety workers can communicate at all times.

“We are pleased to be leading the way with this important public-safety LTE trial,” said Sang-soo Shim, senior vice president of infrastructure business at SK Telecom. “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.”

South Korea first announced city trials in 2015.
