It is critical for the competence of robotic soccer that the wireless communication system transmitts and receives the command-data precisely and rapidly. How to construct a wireless communication system based on Conrad-433/868 wireless communication module in addition to the circuit of the transmitter and the reciever is presented in detail. This system is of advantages such as tiny volume, high integration, high communicating-rate and robustness, easy construction，low cost and without regulating- device，The performance of this system has been verified by the experiments and the competences.
