Marine Wireless Communication
A long-distance communication
A new concept of multimedia marine wireless communication system that enables Internet service
from coast to coast using our tracking antenna + MariCom station without using a high-cost satellite
Characteristics
| Antenna Tracking | A technology to automatically control the position and position of the antenna in a node (base station) that is fluctuating |
|---|---|
| System Bridge | Channel signal code, range analysis, automatic detection from existing channel zone to next channel zone when node is moved, connection to and conversion to the best channel |
| Load Balancing | Maximize communication speed with distributed data transmission for each connecting channel |
| Ad-Hoc | Ability to serve as a communication base for other nodes (base station) |
Influence
- Extensibility to a wide range of fields Overcoming poor marine communications environment,
expected to serve as a springboard for the fourth industry - Low cost, high cost use systems that overcome the limitations of satellite communication used for high cost
Applications
-
Ships
Yacht/reservorboat, Doseons group, General cargo ship, Coastal Passenger ship, Special vessel, drilling vessel
-
Coastal business operators and related authorities
Dongho Society operators such as shipyard, fish farms, fishing, etc., Maritime Police Agency, Port Authority/ Customs

Coastal LTE
It is a communication system optimized for poor marine environment
so that small and medium sized vessels can easily access and receive data through land LTE network.
It can be monitored for the purpose of preventing maritime crime
and protecting offshore environment and fish resources.
Characteristics
| Portable | optimized for poor marine environment by small and medium-sized vessels and offshore operators, enabling connection with existing ISP networks |
|---|---|
| Fast speed and reliability | Secure essentially in hacking as LTE network is connected in an environment separate from the general wireless Internet network. |
Influence
- engine room, wheelhouse / Remote management of loading and operating conditions
- Labor cost savings for barge and special ship / Improving ship owners' management efficiency
- Expansion of human network, such as domestic ship owners and associations
- Protect coastal environment and fish resources
- the prevention of marine crime
Applications
-
Ships
Small to medium size ships, offshore operators, farms
-
Marine technology
smart buoys, ocean wind power generation
Low power communication
LoRa-based low power long distance IoT communication system technology for identification of fishing vessels in offshore environment,
can be applied to various services of long distance communication based on 900MHz license-free frequency band
Characteristics
| High-efficiency structural design | Easy to change structure with flat type dipole array structure and reduce manufacturing cost |
|---|---|
| Using long distance communication module | use Multi-channel base station long distance communication module used for performance enhancement for large-scale IoT terminal identification |
| LBT | Wireless channel collision avoidance and interference avoidance algorithm(LBT : Listen Before Talk) |
| Optimize communication function | Speed dynamic control to extend transmission distance and optimize wireless resource occupation time |
Influence
- Acquisition of maritime IoT technology for marine / fisheries such as fishery, fishing nets, and aquaculture
- Proliferation of IoT service through application of various IoT applications in marine and terrestrial
- Expect new business creation and employment effects such as fishery and farm management services
Applications
-
Real-time monitoring service
for landslide-based or landfill-based landslides / of underground facilities on the road / of ground displacement in tunnel
-
long distance communication technology
Utilization of remote meter reading high reliability long distance communication technology
-
Other
Inter-vehicle communication based on IOT / Inter-vehicle communication
Maritime satellite communication
Cube Satellite - It is called Cube Satellite or CubeSat. It has a volume of
exactly 1 liter of 100mm x 100mm x 100mm high. It uses 1U (Unit) and its weight does not exceed 1 ~ 1.33kg
Characteristics
| High efficiency | Due to the nature of Cubesat, it is more efficient than existing satellite due to the increased performance |
|---|---|
| Low cost | Unlike large satellites that require tens of billions of won, development costs can be as low as 1 ~ 200 million won |
| Activation of high value-added industry | Expected to activate the high value-added industry in Korea |
Infuence
- It is expected to make a lot of contribution from the upcoming 4th industry by increasing the utilization of communication by using the miniaturized satellite to track the position of the ship in the sea, measuring the sea surface water temperature, and monitoring the infrared wide area water temperature.
- We are developing core technology to lead commercialization of low-cost ultra-small marine satellites. We use various high-quality maritime information for various purposes
Applications
-
Autonomous vessel
-
Marine Big-Data
-
Disaster, disaster forecast
