COMMUNICATION DEVICE, COMMUNICATION METHOD, COMMUNICATION SYSTEM, AND COMPUTER PROGRAM PRODUCT

摘要

A communication device includes: a first communication unit that performs wireless communication through a first communication scheme; a second communication unit that performs wireless communication through a second communication scheme in a second communication range; and a connecting module configured to establish a communication connection that forms an external network. The second communication unit transmits setup information for establishing a communication line through the first communication scheme. The first communication unit performs wireless communication through the first communication scheme with another communication device that has received the setup information. The connecting module forms an exclusive external network to establish a communication connection with an external device disposed in a communication system that exists at a physically different place.
