摘　　要：设计并实现了一种基于VoWPAN的新型蓝牙语音中继系统,包括蓝牙电话、网关、耳麦和中继器4种设备.在先期实现蓝牙网关和蓝牙耳麦通信的基础上,进一步实现了蓝牙电话、网关和耳麦任意两者之间的全双工通信,系统内设备通过网关可以接入市话网.系统采用了无中心的通信模型,中继器的使用提高了系统的通信容量和通信距离,设备能够自主选择跳转路径进行通信.阐述了中继器的硬件和软件设计方案,分析了实现的过程、系统干扰情况以及建链时延等参数.A novel Bluetooth relay system based on voice over wireless personal area network （VoWPAN） is designed and implemented. Four kinds of equipments are included in the system, including Bluetooth telephone, audio gateway, Bluetooth headset, and repeater. Based on the communicate between audio gateway and Bluetooth headset, Bluetooth telephone, audio gateway and Bluetooth headset could communicate with each other in full duplex mode. The equipment in this system could communicate with public switched telephone network by audio gateway. A distributed voice communication system module is adopted in the system. The capacity and communication distance of the system are increased by using repeater. The equipment could choose the route by itself. The hardware and software schemes of the repeater design are described in detail and the process for operation is analyzed. The interferences in the system and the delay in linking are studied.
