Samsung and Korea Telecom are to deliver NB-IoT services through a public safety LTE (PS-LTE) network. Samsung has signed an expansion contract with KT to provide PS-LTE network services based on 3GPP standard release 13 for ten major metropolitan regions in South Korea including Seoul by 2020.
This marks the third project in which KT and Samsung’s networks business unit have partnered on PS-LTE network deployments. The two previous projects were the world’s first PS-LTE network throughout Gangwon (Pyeongchang) province of South Korea using 700MHz based on the 3GPP standard in 2016, and the 2017 delivery of an LTE railway service on a high-speed train traveling at up to 250km/hr using MCPTT (mission critical push to talk).
The two companies are now aiming to expand the PS-LTE network further into the metropolitan areas around the country, including 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,” said GY Seo, senior vice president at Samsung Electronics. “Samsung is honoured to take part in this important mission with KT by providing PS-LTE solutions that will ensure seamless and stable connectivity across the nation.”
In addition to LTE radio base stations that support 700MHz, Samsung is providing KT with virtualised core and the latest features of PS-LTE based on the 3GPP standard. Some of the key features include MCPTT, 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) networking.
“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,” said Yoon-Young Park, senior executive vice president at KT. “These first-of their-kind networks help responders connect with those in need.”
D2D and NB-IoT play crucial roles in creating public safety network by ensuring stable, seamless and reliable network in unfavourable environments. For instance, D2D allows direct and undisrupted communications between any two devices without traversing radio base stations or core network even in areas where bases stations are not provided.
For the first time, NB-IoT has been applied to the public safety network to help prevent natural disasters such as fires as hundreds of IoT sensors are deployed to sense even the smallest size of embers or people that have been stranded in remote areas of mountains that are hard to spot in general.
Samsung Electronics has announced the latest addition to its range of semiconductor products. The Exynos i T100 chip joins the previously launched Exynos i T200 and Exynos i S111 to form an integrated range designed to optimise IoT connectivity.
