COMMUNICATION SYSTEM, AND COMMUNICATION DEVICE

摘要

The present invention provides, at a low price, a flexible communication network with a simple configuration for a communication system using wired communication and wireless communication. A communication system (1) contains a first communication device (10) configured so as to be able to perform wired communication and a plurality of second communication devices (20) configured so as to be able to perform not only wired communication but also wireless communication. Each second communication device (20) relays a packet (100) transmitted from the first communication device (10) via wireless communication when said packet (100) was received via wired communication. Each second communication device (20) relays the aforementioned packet (100) via wireless and wired communication when said packet (100) was received via wireless communication.
