A Zigbee Based Framework for Low Power Voice Communication System

Abstract

IEEE standard 802.15.4 defines two layers for low rate WPANs, which are physical layer and media access control layer, which restrict the data rate to 250 kbps. This alliance took low level PHY and MAC layers as the base for the development of the network protocol, security and application for the Zigbee. To solve the Problem of reduce cost and power consumption to make this technology easily available for common crowd. This system shows the total working details of the network, i.e., wireless voice communication. This work has been done to reduce the cost of entire production of such devices that contributes in home automation system and similar projects. The main objective of the research was to transfer voice over low-power micro-controller such as 8-bit micro-controller by the implementation of Zigbee.
