In the ever-evolving landscape of maritime technology, a recent study has shed light on the potential of LoRa (Long Range) technology to revolutionize wireless communication within vessels. The research, led by Kun Yang from the Department of Information Engineering at Zhejiang Ocean University in China, explores the use of LoRa bands for internal wireless networks on ships, aiming to cut down on construction and maintenance costs.
The study, published in the journal “Sensors” (translated from the original Chinese title), delves into the performance evaluation of radio propagation in a vessel cabin using LoRa bands. The researchers measured and analyzed the received signal strength (RSS) and signal to interference plus noise ratio (SINR) to understand the communication link between the deck and the cockpit.
The findings are promising. The mean value of the RSS and the SINR in the cockpit were found to be above -81.70 dBm and 4.45 dB, respectively. This indicates a robust communication link between the deck and the cockpit. “The RSS value acquired by the nodes located on the same side of the gateway is stronger than that of the other nodes,” Yang noted. Additionally, nodes close to the windows showed RSS values that were 6–9 dB higher than those in the middle of the cockpit.
So, what does this mean for the maritime industry? The implications are significant. LoRa technology offers a long-range, low-power, secure, scalable, and robust solution for wireless communication on vessels. This could lead to reduced construction and maintenance costs, as well as improved communication efficiency.
For maritime professionals, this research opens up new avenues for integrating IoT and wireless networks into vessel operations. The potential for enhanced communication links could transform how ships are managed and operated, leading to increased efficiency and safety.
As the maritime industry continues to embrace digital transformation, studies like this one are crucial. They provide a roadmap for adopting new technologies and highlight the commercial impacts and opportunities that lie ahead. With the findings from Yang’s research, the future of wireless communication in the maritime sector looks brighter than ever.
