摘　　要：由于蓝牙工作于极易受干扰的ISM开放频段,所以,研究这一频段设备的干扰特征,对如何提高蓝牙工作性能具有实际意义。首先探讨了蓝牙干扰的理论分析模型,在这个模型的基础上,从IEEE802 11b射频信号发射功率、距离、包长、包速率4个方面对蓝牙的干扰进行了分析。这些干扰因素的分析,对于探讨蓝牙如何与同频段设备共存具有实际意义。Because Bluetooth operates in ISM frequency band, it is important to conduct the research into device interference character of this frequency band for improving Bluetooth performance. On the basis of analyzing Bluetooth interference model, Bluetooth cofrequency equipment interference in the transmit power,distance,packet length and packet speed is analyzed and simulated .The analysis of interference is of significance in exploiting how Bluetooth coexists with cofrequency equipment.
