A survey on implementation of audio over 802.15.4

Streaming an audio over wireless networks is gaining very popularity now days. In view of this IEEE 802.15.4 standard is most used protocol for streaming an audio. It is the Wireless Personal Area Network (WPAN) providing low data rate, low power which is need for long battery life. While streaming an audio the most important factor is the available bandwidth, so the speech samples must be compressed. By compressing an audio a lot bandwidth can be saved, this results in the more samples of speech to be sent on the available bandwidth. In this paper we present a survey on the implementation of audio over 802.15.4 by considering different parameters and speech vocoder because of availability of limited bandwidth.
