 Adding IoT devices can drastically improve your supply chain, allowing you to manage where items are, plan transport and goods handling better, and respond quicker to problems.
 
 When managing a fleet of vehicles such as trucks, it is helpful to know where each vehicle is at a given time. Vehicles can be fitted with GPS sensors that send their location to IoT systems, allowing the owners to pinpoint their location, see the route they have taken, and know when they will arrive at their destination. Most vehicles operate outside of WiFi coverage, so they use cellular networks to send this kind of data. Sometimes the GPS sensor is built into more complex IoT devices such as electronic log books. These devices track how long a truck has been in transit to ensure drivers are in compliance with local laws on working hours.
