Abstract

A system and a method for providing the extensibility of an RF(Radio Frequency) bandwidth on the wireless Internet are provided to offer a wider RF bandwidth to an electronic communication equipment, which uses the wireless Internet, by installing a control part in a mobile terminal, connecting the electronic communication equipment with plural mobile terminals, and expanding an RF bandwidth using the control part. A main mobile terminal, if a wireless Internet access request signal from an electronic communication equipment, confirms whether sub mobile terminals exist(S300,S302). In case it is confirmed that sub mobile terminals exist, the main mobile terminal initializes a communication interface with each sub mobile terminal and grants a unique ID to each sub mobile terminal(S306). Then the main mobile terminal receives raw data from the electronic communication equipment, converts the received data into IP packet data, and executes indexing work to grant sub mobile terminal IDs to the converted IP packet data(S308). Then the main mobile terminal respectively transmits the indexing-completed IP packet data to the sub mobile terminals according to the IDs. The main terminal and the sub mobile terminals transmit the received IP packets using a mobile communication network(S310). Each sub mobile terminal, if IP packet data are received through the wireless Internet, transmits the received IP packet data to the main mobile terminal. The main mobile terminal converts the received IP packet data into raw data and delivers the converted data to the electronic communication equipment(S312).
