KT and Samsung to Expand Public Safety LTE Network Coverage

Going Above and Beyond Public Safety Limitations by way of Key Features of PS-LTE Based on 3GPP Standard Release 13

Samsung Electronics in the present day introduced that it has signed an enlargement contract with KT Corporation (KT) to supply public security (PS-LTE) community options primarily based on 3GPP commonplace Release 13 for 10 main metropolitan areas in South Korea together with Seoul by 2020. In addition, the 2 firms shall be delivering the world’s first Narrowband Internet of Things (NB-IoT) service by way of the PS-LTE community.

This marks the third mission during which KT and Samsung’s Networks Business unit have partnered on PS-LTE community deployments. The two earlier tasks have been the world’s first PS-LTE community all through Gangwon (Pyeongchang) province of South Korea utilizing 700MHz primarily based on the 3GPP commonplace in 2016 (Link), and the 2017 supply of LTE-Railway service on a high-speed prepare touring at as much as 250 km/hour (155 mph) utilizing MCPTT options for the primary time (Link). The two firms at the moment are aiming to develop PS-LTE community additional into the metropolitan areas across the nation, together with Seoul, Gyeonggi, Gangwon, Jeolla, Gyeongbuk and Chungnam provinces.

“Samsung is thrilled to see such a significant achievement in the country’s public safety where our continuous efforts and innovation on technology have advanced the safety of the world,” mentioned GY Seo, Senior Vice President and Head of Global Sales & Marketing, Networks Business at Samsung Electronics. “Samsung is honored to take part in this important mission with KT by providing PS-LTE solutions that will ensure seamless and stable connectivity across the nation.”

“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,” mentioned Yoon-Young Park, Senior Executive Vice President and Head of Enterprise Business Group at KT. “These first-of their-kind networks help responders connect with those in need.”

In addition to LTE radio base stations that assist 700MHz, Samsung is offering KT with virtualized core and the newest options of PS-LTE primarily based on the 3GPP commonplace. Some of the important thing options embody MCPTT options, RAN Sharing, advanced Multimedia Broadcast Multicast Service, Public Network IoT primarily based on NB-IoT, Isolated eUTRAN Operation for Public Safety (IOPS), and system to system (D2D) community options.

D2D and NB-IoT play essential roles in creating public security community by making certain steady, seamless, and dependable community in unfavorable environments. For occasion, D2D permits direct and undisrupted communications between any two units with out traversing radio base stations or core community even in areas the place bases stations usually are not offered.

For the primary time, NB-IoT is utilized to the general public security community to assist forestall pure disasters like fires as lots of of IoT sensors are deployed to sense even the smallest measurement of embers or folks which were stranded in distant areas of mountains which are laborious to identify usually.
