Abstract

Computer-readable media, systems, and methods for wirelessly communicating between a tractor and a set of trailers in a tractor-trailer environment are described. In embodiments, a tractor wireless communication device associated with a tractor is initialized and associated with a tractor initialization time. Additionally, a trailer wireless communication device associated with at least one trailer is initialized and associated with a trailer initialization time. In various embodiments, it is determined whether the tractor wireless communication device and the trailer wireless communication device are in physical proximity by comparing initialization times. Further, in various embodiments, tractor-trailer information events are communicated wirelessly between a tractor and a trailer.
