KT and Samsung to expand Public Safety LTE network coverage

3 May 2019

South Korea’s Samsung Electronics has signed an expansion contract with mobile network operator (MNO) KT Corp to provide public safety (PS-LTE) network solutions based on 3GPP standard Release 13 for ten major metropolitan regions in South Korea by 2020. In a press release the companies say they aim to expand the PS-LTE network into metropolitan areas around the country, including in the Seoul, Gyeonggi, Gangwon, Jeolla, Gyeongbuk and Chungnam provinces. In addition to LTE radio base stations that support 700MHz, Samsung will reportedly provide KT with virtualised core and the latest features of PS-LTE based on the 3GPP standard. Some of the key features reportedly include MCPTT solutions, RAN Sharing, evolved Multimedia Broadcast Multicast Service, Public Network IoT based on NB-IoT, Isolated eUTRAN Operation for Public Safety (IOPS), and device to device (D2D) network solutions. In addition, under the latest deal, KT and Samsung will also seek to deliver ‘the world’s first Narrowband Internet of Things (NB-IoT) service through the PS-LTE network’.

This latest agreement between the two companies marks the third time that KT and Samsung’s Networks Business unit have partnered on PS-LTE network deployments. Previously, the companies rolled out what was claimed to be the world’s first PS-LTE network throughout the Gangwon (Pyeongchang) province of South Korea using 700MHz based on the 3GPP standard in 2016, while 2017 saw the delivery of an LTE-Railway service on a high speed train using MCPTT solutions for the first time.

Commenting on the most recent development, Yoon-Young Park, Senior Executive Vice President and Head of Enterprise Business Group at KT, said: ‘By acquiring innovative wireless communications from Samsung, we are able to aid in life-threatening situations where data traffic is severely congested or connection is completely out of reach … These first-of their-kind networks help responders connect with those in need.’
