SYSTEM AND METHOD FOR TRANSMITTING AND RECEIVING DATA

摘要

PURPOSE: Data transception system and method thereof are provided to make all nodes objecting to data transmission to transmit an electromagnetic wave interference frame by having an electromagnetic wave interference frame during control frame exchange. CONSTITUTION: A judgment unit (320) whether a collision warning message is received in a second time or not. If it is judged as a response message is not received or the collision warning message is received, a third jamming unit (330) transmits a jamming signal to a data reception node. If it is judged as the response message is received and the jamming signal or collision warning message is not received and the data channel use is available, a data transmission unit (340) transmits data to the data reception node.
