Solution Overview
Problem
Small boats navigating at sea face challenges in communicating with a land-based base station due to limited communication range, making real-time data exchange and group communication difficult, as existing solutions like high-power wireless terminals are costly and satellite phones are not viable for them.
Innovation Solution
A marine telecommunications network system that enables communication between small boats and a land-based base station by using telecommunications terminals mounted on each boat to establish communication paths with nearby boats within range, allowing them to relay data to the base station, eliminating the need for high-power terminals and enabling real-time data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a high-power wireless terminal is used to extend communication range, then communication capability beyond base station range is improved, but cost increases significantly
Solution Approach 1:
The communication path is segmented into multiple hops through intermediate boats. Instead of one high-power terminal covering the entire distance, multiple low-power terminals collectively bridge the gap by relaying signals sequentially, reducing individual terminal power requirements and overall system cost.
Solution Approach 2:
Other boats in the vicinity serve as intermediary relay nodes. These intermediate boats receive signals from the boat beyond range and forward them to the base station, enabling extended communication without requiring the original boat to have high-power transmission capability.
2Reliability
If a boat approaches land to within communication range of the base station, then communication is enabled, but real-time data capability is lost
Solution Approach 1:
The system establishes communication paths and relays in advance before the boat needs to communicate. Intermediate boats are positioned and ready to serve as relays, so when data needs to be transmitted, the communication path is already established, enabling real-time capability without requiring the boat to physically approach land.
Solution Approach 2:
Other boats act as mobile intermediaries that bridge the gap between distant boats and the land-based base station. This eliminates the need for boats to physically approach land while maintaining continuous real-time communication capability through the relay network.
3Length of stationary object
If satellite telephones are used for communication at sea, then communication beyond base station range is achieved, but cost becomes prohibitive for small boats
Solution Approach 1:
The system uses multiple inexpensive, low-power wireless terminals on small boats as temporary relay nodes. These terminals are much cheaper than satellite phones and can be easily deployed on small boats, providing cost-effective extended communication through cooperative relaying rather than expensive individual satellite equipment.
Solution Approach 2:
Multiple boats combine their communication capabilities to achieve extended range. Instead of each boat having its own expensive satellite phone, the fleet merges their low-power terminals into a collective communication network, achieving satellite-like range at fraction of the cost through cooperative relaying.

AI summary
There is provided a marine telecommunications network building system to communicate from one of boats navigating on sea to a base station on land with a telecommunications terminal mounted on each of the boats. The telecommunications terminal is configured to build the telecommunication network to establish a communication paths enabling mutual communication between one of the boats exists out of the communication range with the base station and other of the boats that exists within the communication range such that the one of the boats communicates with the base station.
