Abstract :
High quality wireless audio transfer is essential for external digital audio products. There are two kinds of methods for transferring audio data. One is using proprietary RF channel and protocol for reliable audio transfer, the other is using preexisting 802.11 WiFi Network. Audio transfer via WiFi network is more general and preferred method compared to proprietary wireless transfer. But when WiFi traffic is getting heavy, it is difficult to guarantee QoS of audio Data. In this paper, we have proposed independent data transfer using additional USB endpoint for ensuring QoS of data.
