Truck trailer tracking

Necessity is the mother of invention, or so we're told. Schneider National Inc. needed to know what the hell was going on with their trailers so they devised a tracking system with Qualcomm to figure it out. The new trailers include sensors to tell if they're empty or full, as well as sensors to detect if they're connected to a truck or riding on a railroad car. All this data is paired with a tracking system that transmit this data over cellular networks. Makes Smoky and the Bandit seem kind of primitive, doesn't it?
