DATA COMMUNICATION SYSTEM AND DATA COMMUNICATION METHOD

摘要

A system and a method for data communication are provided to process network connection by using a heterogeneous network having short communication distance and simplified authentication processes such as an NFC(Near Field Communication), thereby removing the complexity that a user has to set network connection information one by one and quickly processing network connection. A data communication system comprises first to fourth communication modules. The first communication module(100) forms a first communication network(400). The second communication module(200) forms a second communication network(500) and transmits pre-stored network setup information of the first communication module. The third communication module(340) receives the setup information through the second communication network. The fourth communication module(320) receives the setup information by being the third communication module and forms the first communication network together with the first communication module by using the setup information.
