Korean researchers have achieved a global breakthrough by successfully verifying the world’s first real-world Maritime Internet of Things (MIoT) communication network. Developed by the Electronics and Telecommunications Research Institute (ETRI), the system collects environmental and safety data using sensors installed on ships, ports, and maritime facilities, supporting marine monitoring, navigation, and emergency response.
Long-Distance, Real-Time MIoT Network Achieved in Open Seas
ETRI built and tested an MIoT network across the West and South Seas, achieving communication distances of up to 35 km and simultaneous connection of 30 devices. This marks the first real-ocean verification of IoT technology standardized by 3GPP.
Using the 450 MHz public maritime frequency secured in 2023, researchers established independent base stations at Odongdo Lighthouse (Yeosu) and Maldo Lighthouse (Gunsan). Devices installed at ports and AtoN sites transmitted real data including GPS, battery levels, shock detection, and light status every three minutes.
Successful long-range communication included:
-
27 km between Odongdo base station and Nangdo port
-
35 km between Maldo base station and Janghang port
Commercial testing further confirmed that up to 1,000 IoT devices could connect simultaneously, paving the way for dense maritime IoT coverage similar to land networks.
Foundation for National Maritime Big Data and Safety Infrastructure
The MIoT network is designed as a standalone low-power, low-cost system, optimized for maritime conditions unlike land-based NB-IoT or LTE-M, which either use more power or transmit larger data volumes. The technology enables:
-
Efficient monitoring of weather, ecology, and marine environments
-
Smarter management of lighthouses, aquaculture, fishing gear, and uninhabited islands
-
Public safety applications such as tracking boats, life jackets, and floating debris
The government has aligned with this progress through initiatives including the 3rd Basic Plan for Navigational Aids (2025–2029) and the Marine Navigation Information System Innovation Strategy, with IALA already working toward international standards.
ETRI aims to build MIoT pilot networks in the East, West, and South Seas starting 2026, expanding nationwide after 2030. The achievement may help Korea attract the International Cooperation Center for Navigational Aids and advance overseas technology exports.
ETRI’s successful real-world verification of the maritime IoT network represents a major leap toward a fully connected ocean environment. The technology will strengthen Korea’s maritime safety, support climate response systems, and establish a strong foundation for maritime big-data industries. As Korea advances toward a national MIoT infrastructure, it positions itself as a global leader in next-generation maritime digital transformation.
