Abstract
A communication apparatus includes a wide-area wireless communicator to transmit and receive information to and from a transport vehicle via a wireless access point through wide-area wireless communication, a short-range wireless communicator to transmit and receive information to and from a communication device through short-range wireless communication with a communication range narrower than a communication range of the wide-area wireless communication, and a controller configured or programmed to convert the information received by the wide-area wireless communicator from wide-area wireless communication information into short-range wireless communication information, and output the short-range wireless communication information to the short-range wireless communicator, and convert the information received by the short-range wireless communicator from short-range wireless communication information into wide-area wireless communication information, and output the wide-area wireless communication information to the wide-area wireless communicator.
