Design And Implementation Of Wireless Voice Communication System Based On Zigbee

With the development of science technology, wireless communication is more diversified to meet the needs from the people in different occasions:The traditional telephones, cellphones and others to meet the needs of normal life; at the same time, some self-organization communication systems come out which can work without base stations to deal with several special occasions, such as military and natural disaster relief application, mines, etc.. In this paper, introduces a short distance self organizing wireless voice communication system based on Zigbee technology to achieve the automatic network voice communication in the small scope.This paper analyzes the current development of short distance wireless communication technology, puts forward the overall design scheme of wireless voice communication system based on Zigbee chip CC2530. The system uses CC2530Zigbee chip as the wireless transceiver and network core, FM34NE500B, digital microphone and headset to constitute the voice module, and make the voice module and Zigbee module connected by IIS and SPI ports of STM32F103ZET6to achieve the self-organization voice communication in2000m scope.After the system finished and hardware and software test, it can realize the expected function, meet target of the design. The system has the advantages of low cost, low energe consumption, good communication distance, and it can meet the needs of voice conference, relief and field trips.
