DATA COMMUNICATION SYSTEM, DATA COMMUNICATION DEVICE AND DATA COMMUNICATING METHOD

摘要

A data communication system, a data communication terminal, and a data communication method are provided to connect a computer and a data communication terminal and also connect the data communication terminal and a mobile terminal through a wireless network, thereby transmitting a data file of the computer through a single wireless communication system. The first local area communication module processes a communication protocol that requires an authentication procedure to establish the first communication network. The second local area communication module processes a communication protocol that does not require the authentication procedure to establish the second communication network, and transmits/receives network connection information of the first local area communication module through the second communication network. A transmission interface module is connected with an external terminal and transits data between the external terminal and the first local area communication module.
