Abstract
A communication system includes multiple first communication devices and second and third communication devices. Each first communication device performs first wireless communication using a directive radio wave using first and second function modules; performs second wireless communication wider in communication range than the first wireless communication using a third function module; and generates different network cells. The second communication device performs the first wireless communication with the first function module and connects to one of the network cells. The third communication device manages a multi-hop communication path using the second wireless communication. Each first communication device collects, in the first wireless communication, peripheral communication device information; transmits the information to the third communication device in the second wireless communication; and transfers, in the first wireless communication, data received in the first wireless communication to another communication device, through the communication path instructed by the third communication device.
