MAC protocol, termed Dual Busy Tone Multiple Access(DBTMA), is a random access mechanism with high channel utilization for WLAN.
双忙音多址信道接入（DBTMA）协议是一种信道利用率较高的无线局域网信道随机接入控制方案。
The operation of Dual Busy Tone Multiple Access(DBTMA) is based on the RTS/CTS packet and two narrow bandwidth, outofband busy tones. The RTS/CTS dialogue is used to reserve the channel.
双忙音多址接入（DBTMA）协议是采用RTS/CTS对话机制来预约信道，通过引入两个窄带带外忙音信号来避免分组间冲突，解决了隐藏终端和暴露终端问题。
