Samsung Electronics announced on February 2 that it has signed a contract with KT (Korea Telecom) to provide communications equipment for the disaster relief network of the South Korean government.
Under the contract, Samsung will provide KT with 3GPPR-based LTE network solutions in the top 10 major cities in Korea (Seoul, Daejeon, Daegu, Gwangju, Gyeonggi, Chungnam, Gangwon, etc.) by the end of 2020. At the same time, the two companies will also provide "the world's first narrowband Internet of Things (NB-IoT) business" on the PS-LTE network to help prevent and respond to natural disasters such as fires and trapped in remote mountain areas.
The communication equipment of the South Korean home disaster safety communication network provided by Samsung Electronics is composed of 3GPP standard technology, public Internet, mobile radio and other base station sharing technologies, and multiple simultaneous video transmissions, which are applied to the LTE public network.
In this way, even in extreme environments such as complex terrain, data explosion, and loss of centralized state, the emergency communication network can be effectively protected, thereby establishing a network that can guarantee people's lives in an emergency.
First, the “personal and group emergency call” technology that handles voice and video calls used by field workers is a top priority, ensuring seamless communication between field personnel and ensuring high quality video calls in all situations.
The “Base Station Sharing Technology” can utilize the operator's existing commercial network for national disaster safety network services, providing nationwide services at a lower cost and minimizing shadow areas such as mountains, buildings and underground areas.
Samsung Electronics and KT are using "base station sharing technology", which is used in government departments (police, fire, maritime, municipality, military).
The National Disaster Safety Communication Network uses Internet technology for the first time to connect public Internet objects to low-power and wireless communication devices. It can not only detect rescue activities after an accident, but also detect fire accidents and facility management in real time.
In an emergency, the vehicle type mobile station and the device-to-device that establish the communication network support the mobile rescue operation even in areas where coverage such as mountainous areas is not reached.
In addition, even when multiple simultaneous image transmission technologies optimized for disaster-safe communication characteristics of one-to-many communication are applied for the first time in the national disaster safety communication network and the structural manpower is concentrated at the accident site, more than 2,500 inter-terminal communication can be supported.
In 2017, Samsung successfully tested Mission Critical PTT (MCPTT) technology for seamless video streaming on PS-LTE networks for the first time. These solutions will also be provided in the expansion, as well as multimedia broadcast multicast services.
“The South Korean home disaster safety communication network will become the world's best LTE public network with advanced mobile communication technology,” said Samsung Electronics Strategic Marketing Director. “We have been actively investing in the development of solutions and coexistence with small and medium-sized domestic companies. We will continue to develop technologies and industries that protect people's lives and property.”
