Opening of PS-LTE standard network covering land and sea
By dividing the control center into three and redundant communication equipment
Non-stop operation even in traffic surge situations


On the 26th, KT and Samsung Electronics launched the world's first nationwide National Disaster and Safety Communication Network. The National Disaster and Safety Communication Network is a next-generation wireless communications network, built by the government to efficiently prevent and respond to various major disasters, including natural disasters. It will secure an integrated on-site command system in the event of a disaster and facilitate close cooperation between disaster response agencies.

The disaster safety communications network built by the two companies complies with the 3GPP disaster safety communications standard (PS-LTE). Covering the entire country and sea, the network began pilot and reinforcement projects in 2015. In just six years, it has integrated the wireless communications networks of 333 government agencies across eight sectors, including police, fire departments, national defense, railways, and local governments.

A multi-communications network structure and technology were implemented to support rescue operations even in the worst-case disaster scenarios. Control centers were also established in three locations: Seoul, Daegu, and Jeju. Each station's equipment was also redundant, ensuring uninterrupted operation even in the event of a failure in one unit.

To ensure smooth communication even during peak traffic conditions, eMBMS technology enables real-time communication between up to 2,500 devices. This is more than double the existing TETRA method, which limited the number of devices to 1,200. It also supports direct communication between terminals, enabling communication between field personnel even in areas where wireless base station connections are difficult, such as in mountains or underground.
