Used to deal with lots of shipping containers that contained valuable perishable items. So saw the need for this early on. Tests were already underway then, and makes sense that they have progressed. See also the Maersk work recently mentioned here.
IoT-enabled shipping containers sail the high seas improving global supply chains. in 7wData
Global trade flows through shipping containers. Manufacturers depend on them to get raw materials in time and to ship finished products to market. IoT is being applied to monitor containers and make sure that their contents aren’t damaged or stolen.
Containers have standardized dimensions, which lets transporters easily ship, stack and store them. There are over twenty million containers in motion right now. Containers are pre-filled which reduces the time that trucks need to get loaded. Their standard size allows them to be easily transferred between trucks, planes, ships and trains.
Global supply chains based on containers enable manufacturers to minimize their costs with ‘just-in-time’ inventory. This makes it important to track containers’ location and the condition of their contents.
Containers are made of steel and stacked several deep making communications a challenge. LoRa and WiFi are used for shipboard communication with sensors. Container sensors monitor several parameters: ..... "
