LoRa and modern transport infrastructure

LoRa is a promising new technology based on low power and spread spectrum modulation. It is promising and will help connect and manage the next billion IoT devices. In this paper, we address the implementation of LoRa in modern maritime infrastructure.
The modern maritime ecosystem consists of many elements that work together to process a large amount of data and achieve the desired situational awareness and system management on smart ships. LoRa devices are perfect for this purpose because they are cheap, have long battery life, and are produced in large quantities. We will focus on implementing a LoRa chipset that operates on the globally accepted 2.4 GHz band. Its wireless capability allows sensors to be placed in locations where it was previously not cost-effective, providing a better view of the system, increasing security, and even opening the door for effective predictive maintenance. Two systems are briefly described: a large-scale LoRa pilot project to equip a mid-sized RoRo vessel with LoRa sensors, and the only known commercial solution for monitoring refrigerated containers onboard container ships.
Finally, the use of LoRa is not limited to the transmission of ship or cargo metric sensor data but can also be used for navigation aids. We will present the development of a simple GNSS tracking application and the results of experimental range tests at sea.
